INSTALLATION, OPERATING, MAINTENANCE—JCV 360
3. Operation
The engine is run-in at the factory for 2 hours and requires no further ”breaking in” after installation. All relevant items were adjusted for optimum performance and the carburetor is set to operate satisfactorily between sea level and 2000 meters MSL (6,514 ft MSL) without requiring different jetting or further adjustment. (See note below) Nevertheless, all gauges should be monitored with extra attention during the first few hours of service, with particular attention to the temperature and pressure limitations shown below:
Engine speed:
Maximum speed: 7800 RPM, for 3 minutes maximum Operating speed: 5500 - 6000 RPM It is recommended to maintain operating speed within the range of 5500 - 6500 RPM, where power, fuel consumption and engine wear are in ideal configuration.
Water temperature:
Maximum temp : 100 °C (212 deg F) - For 5 minutes maximum! Operating temp : 75 - 85 deg C (170 - 192 deg F) Minimum temp : 60 deg C (136 deg F) It is forbidden to exceed operating temperature 85°C during engine operation. The maximum temperature 100°C can be used only in the state of emergency and for 5 minutes maximum! Head deflection and other accompanying defects can occur when exceeding ope­rating temperature. The minimum operating temperature 60°C is measured during level horizontal flight and en­gine operation under lower temperature is forbidden.
Exhaust gas temperature:
Operating temp: 620 - 820 deg.C (1150 - 1300 deg.F)
Note:
For reference only: EGT gauge is not a mandatory requirement for this engine.
Oil temperature and pressure:
Oil pressure: 0.3 - 4.0 kg/cm2 (4.35 - 58 psi) Oil temperature: 50 - 85 °C, (122 - 185 deg F), 100° C (212 deg F) for short time only!
Note:
The oil temperature must reach the minimum temperature shown above before the carburetor throttle is wide open and it is the lowest temperature suitable for engine operation. The highest possible oil temperature during engine operation is 90°C and only in the state of emergency can it be exceeded up to 100°C for a short time.
Carburetor throttle must be reduced to minimum flight worthy revolutions and landing made at the nearest landing place if any of above mentioned values get near or reach maximal mentioned limits. Cause of the problem must to be identified and fixed before next flight.

INSTALLATION, OPERATING, MAINTENANCE—JCV 360
4. Items requiring periodic renewal
Some components require periodic renewal throughout the operational life of the engine and these items must be replaced at the intervals specified. Because of a number of operational variables, (atmospheric and weather conditions, frequency of operations, individual preferences, etc.) close and frequent inspection is mandatory to assure that they remain serviceable throughout the recommended replacement interval. Should anything abnormal be noted before the item is due for replacement, it must be replaced without delay. (The remote but realistic possibility of an impending premature failure of the drive belt is an example of this, as discussed below.)
Note:
It is pointed out here that the recommended replacement/renewal periods represent only the reasonably, EXPECTED and not the unconditionally WARRANTED service life of the component in question. In all cases where a component has to be repeatedly replaced sooner than in a specified time, the manufacturer must be notified to investigate the reason and offer a solution for the recurring problem.
Reduction drive belt
The Heavy Duty reduction drive cog-belt requires no maintenance except regular tension check-out and it is not subject to appreciable stretching during the recommended replacement intervals.
The producer is using the belt of kind: type POLY-V 240J/610PJ – width 42mm (USA 240J/18)
Reduction drive belt is tensioned by reduction unit gear shaft. This shaft can be turned after loosing 36S-06-03 and 36S-06-06 screws.
rotating against engine revolutions – reduction drive belt loose + changing rotating by engine revolutions – reduction drive belt tightening
REDUCTION DRIVE BELT HAS TO BE TIGHTENED IN THE DIRECTION OF ENGINE ROTATION!
Tightening strength is about 20 Nm. Tighten first 36S-06-03 screw for 20 Nm and than screw 36S-06-06 for 12 Nm after reduction drive belt exchange.
Check reduction drive belt tension and visual condition before every flight. Exchange reduction drive belt immediately (also independently of exchanging intervals) in case of any defect.
Squeaking sound after quick acceleration or higher revolutions, than maximal RPM adjusted on specific propeller – is caused by loosened reduction drive belt, which must be tightened immediately.

INSTALLATION, OPERATING, MAINTENANCE—JCV 360
Air filter
The air filters should be cleaned in clean solvent periodically. The recommended interval for cleaning the filters in normal conditions is every 25 hours. If the aircraft is operated in exceptionally dusty conditions They should be cleaned more frequently. This is especially true if the aircraft is used for frequent ”touch-and-go” operations in which case weekly clea­ning of the filters is not out of reason. The pulling torque 3 Nm maximum is used when tigh­tening filter clamps; stronger tightening could cut rubber filter cups.
Fuel filter
The fuel filter should be replaced at 25 hour intervals in situations when no pre-filtered fuel is available (e.g. the fuel is loaded from canisters) or at 50 hour intervals if the fuel is always loaded from a properly maintained and approved aircraft fuel tankers or pump.
NOTE: THE PRODUCER RECOMMENDS USING ONLY PAPER MESH FILTERS.
Ignition timing
The checking and adjustment of the ignition timing is illustrated in the Appendix. The adjustment is performed with stroboscope lamp in the way that we mark TDC on the starting disc against fixed point on the engine visible during engine run. Set the speed on 3000 RPM after engine start and read the ignition advance value on stroboscope lamp. This value should be within the range of 25 - 27°.
Spark plugs
The spark plugs should be cleaned in degreasing fluid, using only a stiff plastic brush, and They should NOT be cleaned by means of blasting or sand blasting or cleaned with a steel wire brush.
NOTE: NEVER REMOVE THE PLUGS FROM A HOT ENGINE.
Lubricate the threads of the plug with graphite grease before reinstalling them in the cold engine. Use only spark plugs recommended by a producer; they are checked out in operati­on tests. For cold and damp environment, it is recommended to use conventional spark plugs with earth electrodes NGK CRBE, NGK 9 EK or Champion RG 94 C, RG 92 DC of hotter values. Engine starting will improve even after longer down time.

INSTALLATION, OPERATING, MAINTENANCE—JCV 360
Electronic network, battery:
The engine is using two 12-V batteries that are connected to electronic network. Wiring diagram is on page 19. Recommended batery: 2 x 10 cell NiCad – sub C size cells. Start solenoid, rectifier and voltage regulator are built into the electronic unit. Rectifier/regulator charges both batteries to 12 V. Electric voltage to accessories is 12 V, but there is 24V volts to electric starter for engine starting.
Fuel system:
The engine must be connected to the fuel tank through a fuel filter with paper strainer inside. Fuel tank should be placed above engine – otherwise a check-valve must be installed in fuel hoses. Check-valve prevents drain of fuel back into the fuel tank. Engine electric star­ter can be overheated and battery can be discharged due to long starting caused by fallen fuel level. A plunge primer is suggested to pre-charge the carburetors.
NOTE: IN CASE OF ANY ENGINE FAILURE OR LEAKAGE—IT IS FORBIDDEN TO START ENGINE BEFORE FIXING EVERY PROBLEM
Carburetors:
Engine is equipped with two diaphragm carburetors Walbro WB-37-1. Carburetors are set to operate satisfactorily between the sea level and 2000 meters MSL (6,514 ft MSL). Nevertheless further adjustment is necessary on specific combination of aircraft, propeller and altitude.
Initial Carburetor Adjustment Procedure
For initial adjusting prior to engine start see below (see also illustration on page 21):
1. Idle screw—screw in for 2-3 turns. Procedure: Loosen idle screw so that screw point is gently touching throttle butterfly lever. Then screw idle screw in for 2-3 turns. Repeat same procedure on both carburetors
2. Lo screw— setting engine run on low RPM—loosen for 4-6 turns. Procedure: Screw Lo screw in to the limit— carefully or seat can be damaged— then loosen Lo screw for 4-6 turns. Repeat same procedure on both carburetors.
3. Hi screw—set engine to run at maximum RPM—loosen for 3-4 turns. Procedure: Screw Hi screw in to the limit— carefully or seat can be damaged— then loosen Hi screw for 3-4 turns. Repeat same procedure on both carburetors.

INSTALLATION, OPERATING, MAINTENANCE—JCV 360
IT IS FORBIDDEN TO START THE ENGINE WITHOUT PROPELLER TO PROTECT ENGINE OVERREVVING OR OVERHEATING, WHICH CAN CAUSE ENGINE DEFORMATION.
Adjusting carburetors while engine is running:
Set throttle in position, that engine is idling and let it warm up at least for 50°C (122F) - oil and water.
Set idle to 2300—2600 RPM by adjusting idle screw. (engine must run smooth— otherwise increase idle RPM)
Lo, Hi screws adjusting:
Increase throttle and watch engine run. Two options can happen:
A) Engine is hesitating to speed up and chokes. This is weak mixture case. There is a
serious risk of overherating and seizing of the engine. Engine should speed up easily. Loosen LO screw for 1/8 turn and check engine run again.
B) Engine speeds up easily, but vibrates too much (rough running). This is rich mixture
case. Engine has low power and creates too much carbon particles, which can damage piston and cylinder liner. Screw Lo screw in for 1/8 turn and check engine run again.
Lo screw must be adjusted, so that engine can speed up easily and run smoothly. Lo screw mustn´t be screwed too much in, because that can cause engine overheating
After the engine has been shut down and cooled, the spark plugs should be removed and the color of the ceramic at the points observered. A correct mixture will show a rusty brown color. Light gray to white color indicates a lean mixture that can result in overheating the engine. Dark brown to black color indicates a rich mixture that can result in excess carbon deposits. Note that the plug color test must be done at both low rpm and WOT (wide open throttle) by running the engine for 30-60 seconds at the rpm to be observed. A normal shutdown should be done by moving the throttle to idle, observing the engine is at idle rpm and then shutting down.

INSTALLATION, OPERATING, MAINTENANCE—JCV 360
Hi screw adjusting:
NOTE: THE Hi ADJUSTMENT SCREW WORKS MUCH THE SAME AS THE MIXTURE CONTROL ON A CERTIFIED AIRCRAFT ENGINE THAT IS USED TO LEAN THE ENGINE FOR BEST FUEL CONSUMPTION AND POWER. IF AN EGT GAUGE IS PRESENT IT SHOULD SHOW MAXIMUM TEMPERATURE AT THE MAXIMUM RPM.
- Tie aircraft down to protect from unexpected movement.
- Ensure propeller is clear of obstructions.
- After warmup, apply full throttle and turn Hi screw in or out until you find maximum power (RPM) setting (you can usually find maximum power setting by tightening Hi screw from original setting). This will also be the maximum temperature shown on the EGT gauge.
- Tighten Hi screw (lean the mixture) slowly from maximum rpm position until engine suddenly looses power (drop of RPM caused by excessive lean mixture).
CAUTION:
Immediately loosen Hi screw to maximum engine power setting (otherwise en­gine will overheat and be damaged due to excessive lean condition)!
- Loosen Hi screw for 1/8 of turn from maximal power setting. Never use maximal power setting! Always open (loose) Hi screw for a bit (make richer mixture). Maximal RPM fall about 100 RPM (1/8 Hi screw loosing) compared to maximal RPM setting. (The EGT gauge should show a temperature approximately 100 degrees F less than peak and on the rich side
of peak).
5. Water cooling system—first fill up and working principle
WARNING WARNING WARNING: THIS IS A CRITICAL PROCEDURE
The engine is cooled by liquid flowing through cylinders and cylinder heads. The water pump, which is located at the back side of the engine, pushes this liquid into the cylinders and cylinder heads. The thermostat, situated in each cylinder head, opens and redirects the liquid through the radiator and back into the water pump after heating to a certain level. The cooling system must be installed in such way that air bubbles from cylinders and cylinder heads can flow upwards through hose-pipes into the radiator or into the expansion tank.
11
INSTALLATION, OPERATING, MAINTENANCE—JCV 360
The system must to be perfectly deaerated after filling of the engine and radiator with cooling liquid. See also illustration on page 22. The correct procedure is:
1. Squeeze the hose-pipes until the air bubbles flow into the radiator or expansion tank.
2. Add the cooling liquid as needed.
3. Tilt the engine to one side 30 degrees and again squeeze the hose-pipes till the air bubbles flow out of the system.
4. Put the engine back into the horizontal position and add cooland as needed.
5. Repeat step 3. for 30 degrees tilt to opposite side.
6. Put the engine back into the horizontal position and add cooland as needed.
7. The system is deaerated after this step.
NOTE: IF YOU DO NOT COMPLY WITH THE DESCRIBED PROCEDURE THEN AIR POCKETS MAY FORM CAUSING THE ENGINE TO BECOME OVERHEATED, BE DEFORMED AND DAMAGED.
6. Oil system—first fill up and working principle
There are two outputs for connecting an oil cooler on the bottom of the engine. Oil cooler is not an obligatory part of accessories. Oil cooler does not need to be used if the oil temperature never exceeds maximum values. “Tubular organ“ type oil cooler, made of 8 mm diameter pipes. can be used instead classic oil cooler. Tubular organ type oil cooler functions similar to classic oil cooler, but with less efficiency and smaller space demands. Oil cooler should be placed as near to engine as possible and below the oil sump, otherwise oil pump efficiency can be reduced. Engine can be filled with new oil after oil cooler installation.
NOTE: SEMI-SYNTHETIC OR FULL-SYNTHETIC TYPE JASO MA CLASS OIL FOR 4 STROKE MOTOR­CYCLES CAN BE USED IN ENGINE ONLY.
Filling quantity is about 1 liter for engine and similar amount for oil pipes and oil cooler capa­city. There is an oil level dipstick for checking oil level. Remove spark plugs and crank engine by hand with ignition turned off after filling engine with oil. This procedure may help remove air pocket in the oil system. Then crank engine by electric starter – without propeller and still with ignition turned off. The oil pressure sensor gauge should turn off within 10 seconds. Stop cranking engine and wait a moment if oil pressure light doesn’t turn off by then a moment to allow starter motor to cool and crank engine with electric starter again and watch oil pressure sensor gauge. Always watch electric starter and never let it overheat. Stop cranking engine until electric starter gets cold again in case the electric starter temperature is high. Engine oil system is still aerated if oil pressure light doesn’t turn off.
12
INSTALLATION, OPERATING, MAINTENANCE—JCV 360
WARNING WARNING WARNING: THIS IS A CRITICAL PROCEDURE The correct procedure for deaerating oil system is:
1. Unscrew 36S-07-02 screw from oil filter cover
2. Crank engine by electric starter for 10 seconds. Air from oil system will blow out by the
hole in oil filter cover.
NOTE: engine will blow oil from hole in oil filter cover after blowing air inside oil system. Always catch oil in a container to protect enviroment.
3. Stop cracking engine after first oil blow.
4. Apply Loctite 577 glue on 36S-07-02 screw and screw it gently in
5. Apply graphitic or copper paste on sparkplugs and screw them in
6. Put high voltage cables on sparkplugs
7. Install propeller, torque and lock propeller screws
8. Check if engine satisfies each condition in section “first start“. Turn ignition on and start
engine.
The oil pressure sensor gauge should turn off after 10 seconds – if it does not turn off repeat above procedure!
Warm engine up for 5 minutes on idle and then turn it off. Check oil level on oil level dipstick and fill if needed (up to upper marker on oil level dipstick).
Always follow maintenance schedule for oil and oil filter exchanges. Always empty oil from engine by oil hoses. It is strictly forbidden to screw out oil outlet bushings on the bottom of engine.
NOTE: Producer recommends using Loctite 243 for locking screws on each rotating part. Use only thread lockers with low or middle release moment value, because some Loctite products can lock small diameter screws so firmly, that loosing will be very difficult if not impossible without using very high temperatures.
IT IS FORBIDDEN TO START THE ENGINE WITHOUT PROPELLER TO PROTECT ENGINE OVERREVVING OR OVERHEATING, WHICH CAN CAUSE ENGINE DEFORMATION.
THE ENGINE DOES NOT CONTAIN PRESERVATIVE WITHOUT WRITTEN REQUEST AT TIME OF ORDER — ENGINE MUST BE STARTED FOR THE FIRST TIME AT LEAST 1 MONTH AFTER SHIPPING FROM FACTORY. IF THE ENGINE MUST BE STORED FOR MORE THAN ONE MONTH BEFORE FIRST START PRESERVATIVES MUST BE ADDED TO PROTECT ENGINE PARTS FROM OXIDATION AND DAMAGE. IT IS FORBIDDEN TO START ENGINE WHICH FAILS TO MEET THE ABOVE MANDATE. ENGINE WHICH HAVE BEEN PRESERVATED MUST HAVE THE PRESERVATIVE REMOVED BEFORE FIRST START.
ALWAYS SECURE AREA AROUND ENGINE TO PROTECT FROM PERSONAL INJURY OR OTHER DAMAGE.
13
INSTALLATION, OPERATING, MAINTENANCE—JCV 360
7. Check before first start:
1. Fill engine with recommended type of motor oil (JASO MA 20W-50). Oil level must be up to top scale line of oil level dipstick (see Oil system section). Ensure oil system is de­aerated.
2. Tightness of entire oil system, including oil cooler
3. Fill water cooling system with coolant (specific type and mix according to weather conditions). Ensure water system is de-aerated. (see Water cooling system section)
4. Tightness of entire water cooling system
5. Tightness of exhaust system
6. Tightness and locking engine to engine frame
7. Electrical wiring
8. Tightness of fuel system
9. Operation and symmetry of throttle valves in both carburetors
10. Check torque of propeller bolts
11. Propeller setting (it is forbidden to start engine without propeller to protect engine from over revving, which can cause engine damage)
12. Tie aircraft down to protect from unexpected movement
13. Secure propeller area to protect from personal injury or another damage
NOTE: IN CASE OF ANY ENGINE FAILURE OR LEAKAGE—IT IS FORBIDDEN TO START
ENGINE BEFORE FIXING EVERY PROBLEM
8. First start
1. Hand crank engine at least for three revolutions with switch turned off.
2. Open fuel stopcock.
3. Splash 5 milliliters of fuel in each carburetor over the butterfly valve. (A plunge primer may be installed for this purpose).
4. Set main switch to ON position.
5. Set ignition switch to ON position.
6. Set throttle lever to minimum.
7. Make sure, that nobody is near the propeller before engine start.
8. Start engine.
9. Repeat step 3. if the engine is not able to start within 10 seconds.
10. Start engine and see if engine draws fuel by checking fuel filter .
11. Check oil pressure after engine start. Oil gauge must show required pressure at least 15 seconds after engine start. If oil pressure indicating light is installed, then it must turn off within 15 seconds. If it does not turn of the engine must be turned off and oil lubricating system must be rechecked before another starting. (see Oil system section)
14
INSTALLATION, OPERATING, MAINTENANCE—JCV 360
NOTE: LET ENGINE WARM UP
NOTE: IT IS FORBIDDEN TO TURN OFF THE ENGINE WITH OPEN THROTTLE BUTTERFLY
9.Shutting Down the Engine
It is imperative that the engine is allowed to cool down only gradually, before shutting down,to prevent warping or cracking of the cylinder heads. NEVER (only in the state of emergency) shut the engine down without sufficient cooling period (2 - 3 minutes at minimal speed).
1. Reduce the throttle to 3000 RPM and run the engine at this setting until both cylinder head temperature and cooling water temperature gauges register no more than 80 °C (152 deg F)
2. Switch off all radios and electronics.
3. Carry out the hold off 2 - 3 minutes at 2400 RPM.
4. Reduce the throttle to minimum.
5. Switch off the ignition.
6. Switch off the Master Switch.
7. Close the fuel feed.
NOTE: CHECK ENGINE FOR FAILURE OR LEAKAGE AFTER EACH FLIGHT — ITS FORBIDDEN TO START ENGINE BEFORE FIXING EVERY PROBLEM
!! IT IS FORBIDDEN TO TURN OFF THE ENGINE WITH OPEN THROTTLE BUTTERFLY !!
ALWAYS ADJUST THE PROPELLER BY CANTING THE PROPELLER BLADES SO THAT THE ENGINE SPEED LIMIT DURING LAND ENGINE TESTING DOESN´T EXCEED 7900 RPM. IN CASE OF USING FIXED-PITCH PROPELLER CHOOSE ANOTHER TYPE.
ACCEPTABLE PROPELLERS FOR ENGINE JCV 360 ARE UP TO 150 CM DIAMETER (63 INCH)
15
INSTALLATION, OPERATING, MAINTENANCE—JCV 360
10. Periodic maintenance
After the first flight the engine cowling should be removed, followed by a thorough inspecti­on of the engine compartment. Check the engine for signs of any oil leak at the joining faces of the crankcase, cylinder bases, valve covers and shaft seals. All hoses and wiring to and from the engine should be inspected for looseness, chaffing or any discoloration that might indicate these are routed where excessive heat from the engine could cause premature fai­lure. Check that all components mounted onto the engine mount and firewall have remai­ned securely fastened. Should anything be found damaged, loose, or otherwise indicating any abnormality, the reason for it must be found and the condition must be rectified before the next flight.
11. Major overhauls
The current TBO of the engine is 350 hours, with a view on extending this time in the future. For major overhaul of the engine it must be returned to the factory or to the fully authorized repair facility of VERNER-MOTOR in those countries where the manufacturer is represented by such an arrangement. In case the engine is impacted by a propeller strike or otherwise serious damage, it should be repaired by the manufacturer or authorized representative.
