IV. INSTALLATION of transmitters is normally done at the factory when
the meter is assembled, but may be made in the eld with the meter stopped (i.e. no ow). Depending upon what situation exists, various steps for installation apply and the procedures are outlined below.
1. REMOVE the existing totalizer or indicator or transmitter by removing all the mounting screws and lifting the unit o the meter head.
2. CLEAN METER HEAD of all dirt, glue, gaskets and other foreign material.
3. TOTALIZER DRIVE MAGNET must be removed from the vertical shaft tip of meters equipped with a totalizer so that the transmitter drive clevis (#35) can be installed on the vertical shaft tip. The total­izer drive magnet can be removed by loosening the set screw in the side of the magnet hub and sliding the assembly o the vertical shaft.
4. INDICATOR DRIVE GEAR must be removed from the vertical shaft tip of meters equipped with indicator-totalizers so that the transmitter drive clevis (#35) can be installed on the vertical shaft tip. The indicator drive gear can be removed by loosening the set screw in the side of the gear hub and sliding the assembly o the vertical shaft.
5. TRANSMITTER DRIVE GEAR must be removed from the vertical shaft of meters equipped with an old style McCrometer Model TR01 or TR06. The transmitter drive gear can be removed by loosening the set screw in the side of the gear hub and sliding the assembly o the vertical shaft.
6. VERTICAL SHAFT assembly must be removed from the meters equipped with an old style McCrometer CN06 indicator, TR01 or TR06 transmitter (.100” dia. vertical shaft tip) and replaced with a vertical shaft that has a 3/16” diameter tip. Vertical shaft removal can be ac­complished by removing the two vertical shaft collar bearing mount­ing screws in the meter head and pulling the vertical shaft directly out of the top of the meter. Remove the vertical shaft collar and bearing assembly from the vertical shaft by loosening the set screw in the side of the collar and sliding the assembly o the vertical shaft.
7. REPLACEMENT VERTICAL SHAFT for meters with old style McCrometer models CN06 indicators, TR01 or TR06 transmitters, should be inspected to be sure it is not bent or damaged. Install the vertical shaft collar and bearing assembly on the new (3/16” diameter tip) vertical shaft,
30119-33 Rev. 1.8/04-14

but do not tighten the collar bearing set screw yet. Insert the vertical
shaft assembly, plastic tip rst, into the meter head and rotate the shaft gently until it is engaged in the driven miter gear shaft of the miter gear frame assembly. Set the collar and bearing assembly into the hole in the meter head and replace and secure the two screws that hold the collar bearing in place. Do not over tighten the screws or the bearing can cock and cause drag. Turn the vertical shaft to check for bind or drag. Note: If the meter is in a pipeline full of water, then a slight drag will be created by the propeller moving through the water. Should any bind or drag be apparent it can usu­ally be corrected by adjusting the vertical shaft assembly. Slide the vertical shaft down until it rests against the driven miter gear shaft, then lift the vertical shaft up about 1/64 inch. Tighten the set screw in the side of the collar bearing assembly.
8. ADAPTER PLATE part number A-2-4108, and gasket part number 1558-3, must be attached to the top of the meter head on the old style McCrometer LP21 (3 hole bolt circle) and all ML45, 47 and 49 meters. The adapter plate can be secured to the meter head by three mounting screws (part number 1116-8-12) after the gasket has been centered on the head. Throughout the rest of the instruction manual, the top of the adapter ring will be referred to as the top of the meter head.
9. TRANSMITTER DRIVE CLEVIS (#35) must now be installed on the meter vertical shaft. Place the drive clevis (#35) on the vertical shaft with the forked end up. Position the drive clevis so that the top of the clevis is 1/8” below the top surface of the meter head (on non-reversing models the entire ratchet assembly should be placed on the vertical shaft and the measurement taken from the top of the forked portion). Place the plastic drive clevis coupling (#36) on top of the drive clevis (#35) with the forked portion of the drive clevis fully engaged in the slot in the clevis coupling (#36) and the larger
diameter hole in the coupling (#36) facing up.
10. TRANSMITTER BASE O-RING (#38) should be covered with
a thin coat of silicone grease and placed in the o-ring groove in the bottom of the transmitter base (#11).
11. POSITION OF TRANSMITTER on top of the meter head can be made in one of four directions for the easiest possible reading. Nor­mally the units are attached so that they can be read when looking upstream. Be sure the drive clevis (#35) is in proper alignment and makes a positive engagement with the clevis coupling (#36). Set the transmitter on the meter head and position the driven clevis shaft (#28) so that the slot in the clevis coupling (#36) is properly engaged with the cross pin in the driven clevis shaft (#28). Secure the four mounting screws (#37) .
12. TRANSMIT TER WIRING can be accomplished by following the applicable wiring diagram on pages 13 and 14.
TRANSMITTER OPERATION AND MAINTENANCE MANUAL
V. MCCROMETER products have been carefully designed to be as main-
tenance free as possible. Periodic preventive maintenance, however, is highly recommended and should be practiced according to schedule to assure continuous accuracy and trouble free performance of your transmitter. The maintenance and inspection procedure can also be used as a guide to locating a problem in the unit that may be the cause of abnormal operation.
VI. WORKING AREA chosen for cleaning and inspection of the internal
components should be clean to reduce the chance of dust or dirt particles being introduced into the transmitter mechanism.
VII. TOTALIZER ASSEMBLY (#4) service procedure should include
cleaning and inspection of the unit noting any excessive wear on the change gears (#7 & #8) that may lead to operational problems in the unit.
1. BONNET MOUNTING SCREWS (#3) should be removed and the entire bonnet (#1) lifted o of the meter.
2. TOTALIZER is contained within the totalizer bonnet (#1) and held in place by a base cup (#5). It should not be necessary to remove the totalizer (#4) during inspection; however, removal of the base cup (#5) is necessary for inspection of the totalizer change gears (#7 & #8). Removal of the base cup (#5) can be accomplished by inserting a small screwdriver into the two cutouts and prying upward under the edge.
3. TOTALIZER CHANGE GEARS (#7 & #8) should be inspected for any sign of wear. Both the A-(drive) gear and B-(driven) gear are attached to the lower portion of the totalizer assembly (#4). Spin the oating totalizer driven magnet in the center of the totalizer bottom (#4) to make certain it spins freely without bind or drag. The bottom of the totalizer has the letter “A” molded next to the A-drive gear shaft, and the letter “B” next to the B-driven gear shaft.
4. TOTALIZER DRIVE MAGNET ASSEMBLY (#9) located in the transmitter base (#10) at the top of the driven clevis shaft (#28) should be checked and adjusted if necessary to position it 1/16 inch below the top surface of the transmitter base (#10). Adjustments can be made by loosening the socket head set screw in the side of the totalizer drive magnet assembly (#9), and sliding it up or down the driven clevis shaft (#28) as desired. Always be sure the set screw is tightened into the at on the driven clevis shaft (#28).
‡VIII. INDICATOR-TOTALIZER service procedure should be practiced yearly
and should include removal, cleaning and inspection of the unit not­ing any excessive wear on the gears and other wear points that may lead to operational problems in the unit.

‡ For Indicator-Totalizers Only
‡ For Indicator-Totalizers Only
‡1. BONNET MOUNTING SCREWS (#2) located beneath the
indicator-totalizer bonnet lid, should be removed and the entire bon­net (#1) lifted o of the transmitter. Replace the o-ring seals around each of the four screws (#3) and at the bottom of the bonnet (#4) and cover each of the new o-rings with a thin coat of silicone grease.
‡2. INDICATOR MOUNTING SCREWS (#6) and shake-proof wash-
ers (#7) holding the indicator-totalizer unit (#5) to the transmitter base (#10) should be removed and the unit lifted o, exposing the A-drive gear (#8) attached to the top of the driven clevis shaft (#28).
‡3. METER CHANGE GEARS (#8 & #9) should be inspected for
any sign of wear. The A-(drive) gear (#8) is attached to the top of the driven clevis shaft (#28), and the B-(driven) gear (#9) is attached to the bottom of the indicator (#5). The position of the A-drive gear should be checked and adjusted if necessary to position the top face of the gear 1/8 inch below the top surface of the transmitter base (#10). The position of the B-driven gear top face should be 1/8 inch below the bottom of the indicator-totalizer.
‡4. INDICATOR-TOTALIZER unit (#5) should be cleaned thoroughly
using a mild soap and a soft brush. Under no circumstances should the entire unit be immersed in the soap or should any metal object be used when cleaning and inspecting the internal parts of the indicator­totalizer unit.
‡5. GEARS within the indicator-totalizer unit (#5) should be
inspected carefully. If any excessive wear is visible on the gear teeth, and other wear points, the unit must be returned to McCrometer for repair.
IX. INSPECTION of all internal parts that may be replaced in the eld
has been accomplished at this point. Should any of the parts upon inspection, appear to be damaged or excessively worn, they must be replaced to assure proper operation and prevent further damage.
X. REASSEMBLY is necessary at this point. Before reassembling, make
certain that the unit is cleaned of any dust or dirt. Cost for replace­ment parts not covered by warranty are available from current parts and price list. If it is determined that the unit should be returned for repair, please notify McCrometer prior to shipment. Each unit must be properly packaged to prevent damage to the unit in shipment.
1. TOTALIZER DRIVE MAGNET ASSEMBLY (9) should be checked again to make certain it is properly set to drive the totalizer (#4). (See step VII- 4).
2. TOTALIZER BASE CUP (#5) can be placed back in the totalizer bonnet (#1) on the totalizer assembly (#4) after the desiccant capsule and the base cup o-ring (#6) are replaced and the new o-ring (#6) has been covered with a thick coat of silicone grease. Be sure o-ring (#6) is on base cup (#5) properly. When reinstalling the cup (#5), put two drops of super glue on the inside edge of the bonnet 180° apart and push cup rmly into the bonnet and hold for 30 seconds.
3. BONNET ASSEMBLY (#1) should be cleaned and replaced on the transmitter (#10). Bonnet o-ring (#2) should be replaced and the new o-ring (#2) covered with a thin coat of silicone grease. Secure
four screws (#3).
‡4. CHANGE GEARS (#8 & #9) should be checked again to make
certain they are in proper alignment (see section VIII-3). The gear teeth should be lubricated with a light grease to assure longer life.
‡5. INDICATOR TOTALIZER mechanism (#5) should be placed on
the transmitter base (#10) with the mounting screws and shakeproof washers (#6 & #7). Do not tighten mounting screws (#6) until the gear mesh has been properly adjusted. To adjust gear mesh, slide the indicator-totalizer mechanism (#5) towards the A-drive gear (#8) until the unit stops because of full gear mesh. Now back o the indicator totalizer mechanism 1/64 inch and tighten mounting screws (#6).
‡6. BONNET ASSEMBLY (#1) should be cleaned and replaced over
the indicator-totalizer unit (#5) after replacing the desiccant bag. Secure four screws (#2) beneath the bonnet lid. Do not over tighten the mounting screws (#2) as this will result in damage to the screw o-rings (#3).
XI. TROUBLESHOOTING the transmitter is necessary if it is apparent that
the instrument being controlled by the transmitter is not receiving a proper signal from the transmitter, and/or the totalizer or indicator­totalizer is not functioning. Before beginning, it is important to be sure that the problem is with the transmitter, therefore, the following checks should be made. 1) Check to be sure that water is owing through the meter at ows above the minimum ow rate for the given size meter. 2) Check the instrument to be sure it has the required power being supplied to it. 3) Check the junction box to be sure the communication lines from the transmitter to the instrument are making good contact and that the transmitter is wired properly to the instrument.
1. THE TROUBLESHOOTING GUIDE is provided to help isolate any problem that may occur with the transmitter. Follow the instructions and test procedures listed for each problem.
A. If the meter totalizer or indicator-totalizer does not work, but
the remote instrument does operate (receiving the proper signal), then see section VI, VII-1 thru 4, IX and X-1 thru 3 for checking the totalizer, or section VI, VIII-1 thru 5, IX and X-4 thru 6 for checking the indicator-totalizer.
