TROUBLESHOOTING FOR THE POWER SHUTTLE
Check to Do Before Testing
1. Change the oil in the power shuttle and torque converter and clean the suction screen in the power shuttle according to the instructions under Oil Change on page 2.
2. Check the level of the oil in the power shuttle according to the instructions under Oil Level on page 3.
3. Do the stall checks according to the instructions in Section 2002.
4. Check the adjustment of the linkage for the power shuttle control lever. Make sure that the control arm on the control valve spool can move into the detent positions.
If adjustment is necessary, see Section 6211.
Testing the Power Shuttle with a Pressure Gauge
General Information
There is a check sheet at the end of this section. Make a copy of the check sheet. Use the check sheet to write a record of the indications found in the pressure gauge tests.
See the illustration above for location of test ports.
Test No. 1 – Clutch Circuits
1. Remove the 1/8 NPT Allen head plug from the test port for test No. 1. See location of test port above.
2. Connect a pressure gauge to the test port. The pressure gauge must be accurate in the range of 0 to 300 psi (0 to 2068 kPa, 21 bar).
3. Start the engine. Run the engine at low idle.
4. Read the gauge for oil temperature. The pointer in the gauge must be in the center of the green area.
5. If the temperature is not correct, do the following:
a. Make sure that the parking brake is applied.
b. Move the transmission control lever to fourth and the direction control lever to FORWARD.
c. Slowly increase the engine speed to full throttle. If the machine moves, decrease engine speed and stop the engine. See Section 7106 and adjust the parking brake.
d. Run the engine at full throttle for 40 seconds.
e. Continue to run the engine at full throttle with the direction control lever in NEUTRAL for 10
seconds.
f. Decrease the engine speed to low idle.
g. Repeat steps 5c through Sf until the pointer in the gauge for oil temperature is in the center of the green area on the gauge.
h. Decrease the engine speed to low idle. Move the direction control lever to NEUTRAL, and the transmission control lever to NEUTRAL.
6. Read the pressure gauge. Write the reading on line 1 on the check sheet.
7. Increase the engine speed to full throttle. Read the pressure gauge and write the reading on line 2 on the check sheet.
8. Decrease the engine speed to low idle.
9. Move the direction control lever to FORWARD. Read the pressure gauge and write the reading on line 3 on the check sheet.
10. With the direction control lever in FORWARD, increase the engine speed to full throttle. Read the
pressure gauge and write the reading on line 4 on the check sheet.
11. Decrease the engine speed to low idle.
12. Move the direction control lever to REVERSE. Read the pressure gauge and write the reading on line 5 on the check sheet. ·
13. With the direction control lever in REVERSE, increase the engine speed to full throttle. Read the pressure gauge and write the reading on line 6 on the check sheet.
14. Decrease the engine speed to low idle and stop the engine.
15. Disconnect the pressure gauge and install and tighten the plug for the test port.
Test No. 2 – Cooling Circuit
1. Remove the Allen head plug from the test port for Test No.2.
2. Connect a pressure gauge to the test port. The pressure gauge must be accurate in the range of 0 to
150 psi (0 to 1 034 kPa, 0 to 10.3 bar).
3. Start the engine. Run the engine at low idle.
4. Make sure that the transmission control lever and the direction control lever are in NEUTRAL.
5. Increase the engine speed to full throttle.
6. Read the pressure gauge. Write the reading on line 7 on the check sheet.
7. Decrease the engine speed to low idle.
8. Move the direction control lever to FORWARD.
Increase the engine speed to full throttle.
9. Read the pressure gauge and write the reading on line 8 on the check sheet.
10. Decrease the engine speed to low idle.
11. Move the power shuttle control lever to REVERSE.
Increase the engine speed to full throttle.
12. Read the pressure gauge and write the reading on line 9 on the check sheet.
13. Decrease the engine speed to low idle and stop the engine.
