GENERAL DESCRIPTION:

The Malabar Fixed Height Tripod Jack Model 795 is a 100 ton capacity single stage hydraulic jack
designed primarily for use in aircraft maintenance. It consists of a tripod structure, hydraulic cylinder
assembly, reservoir, valve block assembly, hand pump assembly, tow handle, swivel casters and the
following optional equipment:

*Air pump

*Electric motor operated hydraulic pump

*Load gauge

*Adjustable swivel foot

*Adjustable swivel foot with hydraulic caster

*Ladder

*Remote control (platform operated)
The jack tow handle readily connects to tow vehicle for ease of transport. The jack should never be used
as a personnel carrier while being towed or in motion. On jacks equipped with spring loaded swivel
casters, the jack leg pads are raised off the ground. The casters will retract and the pads rest on the
ground when a load is applied to the jack. On jacks equipped with adjustable swivel foot, the jack leg

pads have adjustable leveling feet for slightly uneven or sloping floors. On jacks equipped with hydraulic
casters, leveling of the jack is faster and easier by selectively extending or retracting the caster plungers
utilizing the caster hand pump or release valve. Extending the casters also increases the towing ground
clearance. For extended towing over rough surfaces, a hydro-pneumatic shock absorber is provided to
cushion against towing loads and improve caster life.

PREPARATION FOR USE:

Disregard the following erection procedure if the jack is shipped fully assembled. If the jack is shipped
partially assembled, erection is accomplished by following the suggested sequence below (also see
figures 1A & 1B):

1. Install sling under tripod head of cylinder assembly and support from a crane or forklift capable of
lifting 6000 pounds to a height of 12 feet.

2. Install legs, tripod head pins and retaining rings.

3. Install braces.

4. Tighten all bolts.

If jack is equipped with adjustable swivel feet, perform the following procedure to calibrate bubble level:

1. Hang 2 plumb bobs (at 90°) from the tripod head with the plumb bob strings approximately parallel to
the cylinder assembly (dial indicator magnetic bases work well as supports for the plumb bobs).

2. Stand on jack footpads and screw the footpad locknuts up to the end of the legs, continue turning
footpad locknuts until weight of jack is off casters (one end of the pump handle fits into the footpad
locknuts to provide extra leverage if required). Adjust footpad locknuts so both plumb bob strings are
parallel to the cylinder assembly (carefully measure top and bottom from cylinder assembly to
strings). Alternately, if jack is equipped with hydraulic casters, operate hydraulic caster hand pumps
and/or release valves to extend or retract casters until both plumb bob strings are parallel to the
cylinder assembly.

3. Remove cover from bubble level and adjust screws to center bubble. Lock adjustment screws and
replace cover. Tag with date of calibration.

4. Raise footpads fully to stow position and reinsert pump handle in handle holder. Remove plumb bobs.

5. Bubble level should be checked periodically as directed by cognizant quality control department.

Before placing jack in operation, perform the following procedure:

1. Remove filler cap from the filler spout located at the side of the reservoir.

2. Fill jack reservoir to mark on dipstick with MIL-H-5606 hydraulic fluid or approved equivalent
(reservoir capacity is approximately 26 gallons/98.4 liters). Jack plunger must be fully retracted before
filling reservoir. Replace filler cap.

3. Open release valve and operate hand pump a few strokes to bleed all air trapped under hand pump.

4. Close release valve and operate hand pump to raise plunger approximately 1 inch.

5. Open release valve to retract plunger fully to bleed all air trapped under jack plunger. Close release
valve.

6. If jack is equipped with hydraulic casters, perform the following procedure:

a. Remove the elbow/breather located on top of the reservoir.
b. Open release valve and fully retract caster plunger.
c. Fill reservoir to the top with MIL-H-5606 hydraulic fluid or approved equivalent. Replace

elbow/breather.

d. Open release valve and operate hydraulic caster hand pump a few strokes to bleed all air trapped

under hand pump.

e. Close release valve and operate hand pump to extend caster approximately 1 inch.

f. Open release valve to retract caster fully to bleed all air trapped under plunger. Close release

valve.

g. Repeat for other hydraulic casters.

7. If jack is equipped with shock absorbers for the hydraulic casters, remove valve cap at end of unit and
charge with nitrogen gas to 275 psig (19.3 kg/sq cm) using accumulator test gauge assembly (P/N

872845).

8. If jack is equipped with electric motor operated hydraulic pump, note factory wired for 460V. Internal
wiring changes are required for 230V.

PRE-OPERATION INSPECTION:

Each time the jack is to be used, inspect the following:

1. Check the tripod structure for rigidity. Make sure all bolts are tightened.

2. Check hydraulic line connections for leaks. Tighten as required.

3. Check for hydraulic fluid leaks around the base, reservoir, tripod head, hand pump, air pump (if so
equipped), hydraulic casters (if so equipped) and shock absorber (if so equipped).

4. Check hand pumps for proper operation.

5. Check swivel casters for proper operation.

6. Check jack reservoir fluid level with plunger fully retracted.

7. Check hydraulic caster reservoir fluid levels with caster plungers fully retracted (if so equipped).

8. Check nitrogen charge in shock absorbers (if so equipped).

OPERATION:

CAUTION: PRIOR TO TOWING, ENGAGE THE TWO TRAILING SWIVEL CASTER

LOCKS. ON JACKS EQUIPPED WITH ADJUSTABLE SWIVEL FOOT,
ALWAYS FULLY RETRACT THE FOOTPADS BEFORE MOVING OR
TOWING THE JACK. ON JACKS WITH HYDRAULIC CASTERS, FULLY
EXTEND CASTERS BEFORE MOVING OR TOWING JACK.

1. Position the jack under the jacking pad of the aircraft. For maximum maneuverability, verify all swivel
caster locks are disengaged.

2. Raise the extension screw by turning counterclockwise until the ship adapter contacts the jacking pad
or as far as the screw will travel (24 inches maximum).

3. Verify the jack is leveled (shim footpads if necessary). The jack plunger should be plumb during
lifting. On jacks equipped with adjustable swivel foot, check level using the bubble level mounted on
the jack. Adjust the footpads to contact the ground and plumb the jack. The footpads are adjusted by
standing on the footpad and adjusting the footpad locknut as required to extend the footpad. One end
of the pump handle fits the footpad locknut for final adjusting. On jacks equipped with hydraulic
casters, operate hydraulic caster hand pumps to extend casters to plumb the jack and then adjust the
footpads to contact the ground.

CAUTION: OPEN HYDRAULIC CASTER RELEASE VALVES TO ENSURE THE

WEIGHT IS TAKEN THROUGH THE FOOTPADS

CAUTION: ON JACKS EQUIPPED WITH AIR PUMP, AIR RELIEF VALVE MUST

BE INSTALLED AT ALL TIMES. IF AIR RELIEF VALVE IS REMOVED,
IT IS POSSIBLE TO OVER PRESSURIZE THE PNEUMATIC SYSTEM
WHICH COULD CAUSE EQUIPMENT FAILURE AND POSSIBLE
BODILY INJURY.

4. On jacks equipped with air pump, connect air supply (90-110 psig) to the 1/2 NPT air inlet at the air
valve (a minimum of 56 scfm is required). Air relief valve must be properly installed. Do not attempt to
remove air relief valve.

CAUTION: LOCKNUT MUST BE INSTALLED AND OPERABLE ON JACK AT ALL

Property of American Airlines

TIMES. ALWAYS MAINTAIN LESS THAN 2 INCHES BETWEEN THE
LOCKNUT AND THE TRIPOD HEAD IN ALL PHASES OF LOAD
RAISING AND LOWERING.

5. On jacks equipped with electric motor operated hydraulic pump, connect power supply (230/460V,
60 hertz) to the switch box. Note: Factory wired for 460V. Internal wiring changes required for
230V.

6. To raise the load manually:
a. The jack is equipped with an adjustable hand pump. The hand pump handle length can be varied

by inserting the quick release pin through the clamp and appropriate hole along the handle (see
figure 4). A longer handle length provides greater pumping leverage for high pressure pump
operation. A shorter handle will increase the plunger stroke and allow more oil pumped per stroke.

This permits a more rapid raising of the jack plunger under a light or no load.
b. Close release valve located on the panel.
c. Operate the air valve or electric motor or hand pump until the ship adapter contacts the jacking

pad. Insure the ship adapter and the jacking pad are correctly mated. The load may now be raised

by operating the air valve or electric motor or hand pump.
d. Do not lift a load greater than the rated capacity of 100 tons.
e. Do not attempt to raise the plunger beyond the rated hydraulic lift (72 inches maximum).

f. Avoid lifting with excessive side load on the jack.
g. Spin the locknut down to the tripod head, as plunger is extending.
h. Keep the release valve closed at all times.

7. To lower the load:
a. Operate the air valve or electric motor or hand pump to relieve pressure on the locknut.
b. Spin the locknut out of the way.
c. Slowly open the release valve located on the panel to lower the load. The speed of lowering is

controlled by the amount the release valve is opened.
d. Close release valve after the plunger is fully retracted.
e. Lower the extension screw by turning clockwise.

f. Fully retract the adjustable footpads (if so equipped).
g. Fully extend hydraulic casters (if so equipped).
h. Cover the jack when not in use to prevent entrance of contaminants and water into the cylinder.

SERVICING:

Servicing the jack consists primarily of the following:

1. When in use, the jack and hydraulic caster (if so equipped) reservoirs should be kept at the proper
level with hydraulic fluid MIL-H-5606 or approved equivalent. Always check fluid levels with jack and
hydraulic caster plungers fully retracted.

2. When in use, the nitrogen precharge in the hydraulic caster shock absorbers (if so equipped) should
be maintained at 275 psig (19.3 kg/sq cm).

3. Grease the swivel casters.

4. Lubricate hand pump pivot pins.

5. Fill pump lubricator with SAE #10 oil.

6. If the jack has been put into storage or has not been used, the plunger must be fully extended and
retracted every 90 days to exercise the seals. A portion of the lift should be operated by the air pump
(if so equipped) and a portion by the hand pump. Also, the hydraulic caster plungers must be fully
extended and retracted by operating the hydraulic caster hand pumps and release valves.

DISASSEMBLY INSPECTION:

± 20 psig (63.3 ± 1.4 kg/sq cm) IF ADJUSTMENT IS REQUIRED, SEE
PROCEDURE UNDER TESTING (SEE SHEET 5).

When necessary to disassemble the jack and/or the hydraulic casters (if so equipped), open all release
valves, drain all hydraulic fluid from reservoirs and carefully inspect the following:

1. Inspect interior walls of cylinders for smoothness and freedom from rust, nicks, scratches and
excessive wear.

2. Check plungers, extension screw, cylinders, tripod head, etc., for corrosion, wear and condition of
threads.

3. Verify that the extension screw has a positive stop to prevent it from being extended beyond its safe
thread engagement.

4. Inspect packings, seals, gaskets and wipers in the cylinder assembly, hand pumps and hydraulic
caster assemblies for cuts, scratches, deterioration and distortion.

5. Inspect upper and lower bearings for excessive scoring and/or wear.

6. Check oil screen located in the valve block for cleanliness.

7. Inspect valves and valve seats in the hand pump bodies and valve blocks for scratches, dents and
proper seating of the balls.

8. Inspect all pivot pins for wear, cracks, pits or evidence of damage or pending damage.

9. Check tripod structure for damages.

10. Inspect all areas for excessive dirt, oil, dust and chips.

REPAIR AND REPLACEMENT:

No definite time schedule can be established for the overhaul of the jack for replacement of the various
moving parts. The number of times the jack is raised and lowered and the amount of load raised at each
operation materially affect the life of the working parts. Do not overload the jack. Overloading is
dangerous, will hasten the need for overhaul and may damage the jack. During overhaul, replace all parts
that do not pass disassembly inspection requirements. Regardless of apparent condition, replace all parts
marked with (♦) and (✚) in the parts breakdown. A repair parts kit (P/N 795PK) which contains all of the
parts marked with (♦) and a hydraulic caster repair parts kit (P/N 8818PK) which contains all of the parts
marked with (✚) are available and recommended to keep on hand at your facility. Coat all O-rings and
back-up rings with hydraulic fluid MIL-H-5606 prior to assembly. Clean all metal parts with clean solvent
and dry with compressed air. Lubricate all threads. Use teflon tape carefully on all pipe threads. Remove
excess tape because it can clog valves and passages. If ball valves, located in valve blocks, do not seat
properly, they may need to be reseated by tapping the ball into the valve seat with a brass rod cupped at
one end.

TESTING:

Place jack in a load indicating test fixture. Make sure the test adapter is 1 1/4 inch female spherical
radius. Operate jack hand pump to extend plunger against the test adapter. Make sure ship adapter and
test adapter are correctly mated. Load test the jack at rated capacity of 100 tons. If the jack fails to
operate properly, check for trouble as indicated in the Trouble Shooting Chart (see sheet 12). With the
plunger extended and supporting the capacity load, allow the jack to stand for 10 minutes. Any excess
settling indicates leakage in the hand pump, check valves or jack packing seals. Check for hydraulic fluid
leaks and replace all defective parts.

If adjustment is required for the jack thermal relief valve, perform the following procedure:

1. Remove plug (figure 3, item 8) to expose thermal relief valve. Close release valve (figure 3, item 2).

2. Place jack in a load indicating test fixture. Make sure the test adapter is 1 1/4 inch female spherical
radius. Operate hand pump to extend plunger against the test adapter. Make sure ship adapter and
test adapter are correctly mated.
