Engine - Prepare for stall tests
Perform the stall test to find the cause of poor performance.
The main relief valve must be set within specifications to achieve accurate readings when performing the following
stall tests.
The engine is run at full throttle and the transmission and hydraulic systems are engaged separately, and then to-
gether.
Comparing the engine speeds from the stall test with the check sheets in this section will help to find the cause of the
problem. It can be necessary to check a separate system to find the exact cause of the problem.
Use a photo tachometer or other tachometer of equal accuracy to get accurate results from the stall test.
The engine, transmission and hydraulic system must be at operating temperature before doing the stall test. Heat the
oil according to instructions in this section.
Machines with standard transmission
NOTE: Check the throttle linkage adjustments.
1. Apply the parking brake.
2. Move the transmission gear selector into fourth gear.
3. Lock the brake pedals together. Put your foot on
the service brakes and hold the machine with service
brakes.
4. Release the parking brake.
5. With the engine running at low idle, move the direc-
tion control lever forward.
6. Slowly increase the engine speed to full throttle.
7. If the machine begins to move at any time, decrease
the engine speed to low idle and stop the engine.
Procedure to heat torque converter and hydraulic oil
1. Apply the parking brake.
2. Start and run the engine at low idle.
3. Run the engine at full throttle, hold the loader control
lever in the rollback position for 15 seconds.
4. Return the loader control lever to neutral for 15 sec-
onds.
5. Repeat steps 3 and 4 until the temperature of the oil
is 52 °C (126 °F). The side of the reservoir will be
very warm at this temperature.
6. With the engine running at low idle, move the trans-
mission control to fourth gear and the direction con-
trol lever to forward.
7. Run the engine at full throttle for 15 seconds.
8. Decrease the engine speed to low idle and move the
direction control lever to neutral for 15 seconds.
9. Repeat steps 6 through 8 until the pointer in the
gauge for transmission oil temperature is in the cen-
ter of the green zone of the gauge for transmission
oil temperature.

Stall test procedure
1. Prepare the machine for the stall test according to
instructions in this section.
2. Heat the oil according to instructions in this section.
3. Apply the parking brake and start the engine.
4. With the engine running at full throttle, hold the loader
control lever in the lift position and read the tachome-
ter. Record the reading on line 1 of the check sheet.
5. Decrease the engine speed to low idle.
6. Move the transmission control lever to fourth gear.
7. Lock the brake pedals together. Put your foot on
the service brakes and hold the machine with service
brakes.
8. Release the parking brake.
9. Move the direction control lever to forward.
10. Slowly increase the engine speed to full throttle and
read the tachometer. Record the reading on line 3
on the check sheet.
11. With the transmission control lever in fourth gear, the
direction control lever in forward, and the engine run-
ning at full throttle, hold the loader control lever in
the lift position and read the tachometer. Record the
reading on line 4 on the check sheet.
12. Decrease the engine speed to low idle, move the
directional control lever to neutral.
13. Run the engine at low idle for two minutes and then
stop the engine.
14. See the check sheet to understand the results of the
stall test.
