6V-3965 Fitting As must be installed into the transmission in order to perform some tests.

Sudden movement of the machine or release of oil underpressure can cause injury to persons on or near themachine. To prevent possible injury, perform the procedurethat follows before the test is done.

Note: For all tests, the machine must be at operating temperature.

Transmission Pressure Test

Test Points 2 Wheel Drive All Wheel Drive

Pump Pressure at High Idle 1525 ± 175 kPa (220 ± 25 psi)

Forward Clutch Pressure at Low Idle 1410 ± 100 kPa (205 ± 15 psi)

Reverse Clutch Pressure at Low Idle A result within 25 kPa (3.6 psi) of Forward clutch pressure

Lubrication Pressure at Low Idle 120 ± 90 kPa (17 ± 13 psi)



Pressure for the All Wheel Drive Clutch N/A 1410 ± 100 kPa (205 ± 15 psi)

Removal of the Floorplate

Test for the Transmission Oil Pump Pressure

This test will show if the transmission oil pump is good.

Illustration 5 g00759493(10) Transmission pump pressure



1. At pressure tap (10) , connect 198-4240 Digital Pressure Indicator .

2. Place the direction control lever in NEUTRAL. Also place the speed shift lever in NEUTRAL.

3. Activate the parking brake. Start the engine and run the engine at low idle.

4. Shift the direction control lever to FORWARD. Run the engine at high idle. The pressure should beapproximately 1525 ± 175 kPa (220 ± 25 psi).

5. When this test is complete, reduce the engine speed to low idle. Place the direction control lever inNEUTRAL. Stop the engine and remove the equipment.

Test for the Torque Converter Stall

The test will show if engine performance is good. The test will show if the torque converter operatesproperly. Also, the test will show if there is oil flow through the oil cooler.

Note: Any unusual noises during this check should be noted. Loud noises could indicate that repairs areneeded.

1. Start the engine and run the engine speed at low idle.

2. Lower the stabilizers and lift the rear wheels about 150 mm (6 inch) off the ground.

3. Place the bucket hydraulic controls in the lowering position. Lift the front wheels about 150 mm (6inch) off the ground.

4. Stop the engine and proceed with the following procedure.

5. Install the 6V-3121 Multitach on the engine. The multitach can measure engine speed by the useof a photo pickup and reflective tape. The Special Instructions, SEHS7807 has instructions for theuse of the multitach.

6. With the transmission shift lever in (NEUTRAL) position, start the engine and run the engine at lowidle. Ensure that high idle rpm and low idle rpm are correct. Refer to Engine supplement,SENR5815, "3054 Engines for Caterpillar Built Machines".

NOTICETo ensure that the transmission oil does not overheat, donot keep the torque converter in a full stall condition formore than 30 seconds. After the torque converter stall test,reduce the engine speed to low idle. In order to cool theoil, move the transmission control to the NEUTRAL positionand run the engine between 1200 rpm and 1500 rpm.

7. Run the engine at high idle. Fully engage the brakes. Run the transmission at normal operatingtemperature 59 to 71°C (138 to 160°F). Shift the speed shift lever to FOURTH SPEED. Shift thedirection control lever to FORWARD and stall the torque converter until the temperature of theconverter reaches 90 to 93°C (194 to 200°F). Table 4 contains the correct stall RPM for thevarious horsepower ratings of the engines that are installed in machines.

Table 3

Direct Drive Transmission Arrangement

Horsepower Rating Stall RPM



75 hp 2084 ± 75 RPM

80 hp 2143 ± 75 RPM

85 hp 2210 ± 75 RPM

93 hp 2247 ± 75 RPM

Note: Stall speeds are calculated using No. 2 diesel fuel.

8. When the test is complete, put the direction control lever in NEUTRAL and the shift lever inNEUTRAL. Stop the engine and remove the test equipment.

Note: Do not keep the torque converter in a stall condition for very long periods of time. The torqueconverter, the engine, and the brakes will get hot.

Problem

The oil gets too hot during normal operation.

Probable cause

1. Not enough oil is in the torque converter because the inlet relief valve for the torque converter isopen.

2. The oil pump fails.

3. The torque converter fails.

4. The temperature gauge is bad. Replace the temperature gauge and the sending unit.

5. The air flow to the oil cooler is blocked by debris. Debris could also be blocking air flow to theengine cooler.

Problem

High idle is correct, but stall speed is too high.

Probable cause

1. The torque converter is bad.

Problem

Stall speed is low.

Probable cause

1. There is an engine problem.

Test for Clutch Oil Pressure and Transmission Lubrication

This test will show if oil pressure to the forward clutch and the pressure to the reverse clutch is good.The test will also show if the transmission lubrication circuit is good.

1. Install the 6V-3121 Multitach on the engine. The 6V-3121 Multitach can measure the enginespeed by the use of the photo pickup and the reflective tape. The instructions for the use of thephoto pickup and reflective tape are in Special Instruction, SEHS7807.



Illustration 6 g00759511(12) Forward clutch pressure

(13) Reverse clutch pressure

2. At pressure taps (12) and (13) , connect 198-4240 Digital Pressure Indicator .



4. Start the engine and run the engine at low idle.

5. Shift the direction control lever to FORWARD, and shift the speed shift lever to NEUTRAL. Thepressure for the forward clutch should be approximately 1410 ± 100 kPa (205 ± 15 psi). Thelubrication pressure must be 120 ± 90 kPa (17 ± 13 psi). The reverse clutch pressure should be 0kPa (0 psi).

6. Now shift the direction control lever to REVERSE, and shift the speed shift lever to NEUTRAL. Thereverse clutch pressure shall be within 25 kPa (3.5 psi) of the pressure in the FORWARD at thesame engine speed. The lubrication pressure should be approximately 120 ± 90 kPa (17 ± 13 psi).The forward clutch pressure should be 0 kPa (0 psi).

7. When the test is complete, put the direction control lever in NEUTRAL, and engage the parkingbrakes. Stop the engine. Remove the test equipment.

Problem

Both forward clutch pressure and reverse clutch pressure is too low.

Probable Cause



1. The spring to the system relief valve is weak.

2. The oil level is low.

3. The oil filter is plugged. Replace the dirty oil filter.

4. Oil pump failure.

5. The neutralizer button that is on the shift lever or the tilt control lever shorted. This caused thesolenoid control valve to de-energize.

6. The clutch piston seals are bad.

Problem

Either the forward clutch pressure or the reverse clutch pressure is too low.

Probable Cause

1. The solenoid is faulty.

2. The clutch piston seals are bad.

3. The seals are faulty or the seals are missing on the input shaft.

Test for the All Wheel Drive (if equipped)

Illustration 8 g00872331(15) All wheel drive pressure


2. Start the engine and run the engine at low idle.



Illustration 9 g00872352(16) All wheel drive switch

3. Engage the all wheel drive by pressing the left side of the all wheel drive switch (16) . Thepressure for the all wheel drive should be approximately 1410 ± 100 kPa (205 ± 15 psi).

4. When the test is complete, press the right side of the all wheel drive switch (16) in order to returnthe machine to the two-wheel drive mode, and engage the parking brakes. Stop the engine.Remove the test equipment.
