INSTRUMENTATION CLUSTER - TRANSMISSION LEAKAGE CHECK
The regulated circuit pump is the front section of the tandem gear pump. The pump draws oil from the system
reservoir through a 100 mesh suction screen. The pump flow passes through the regulated circuit filter housing
and into the priority regulator valve. The priority regulator valve maintains the regulated pressure circuit at 22.4 to
24.5 bar (325 to 355 PSI). The regulated pump flow supplies the PTO/ Diff lock valve, transmission control valves
and brake valve. Both the remote and hitch valves are also supplied with pilot pressure.
Once these circuits are satisfied the excess regulated pump flow is directed through the oil coolers and joins up
with the charge pump flow at the downstream side of the main filter head.
The 27 GPM tandem gear pump is a fixed displacement pump, therefore the output flow will decrease as the
engine speed is lowered. At low engine speeds, leaks in the regulated and transmission circuits are more
noticeable.
BACKGROUND INFORMATION:
The transmission controller monitors the pressure through the system pressure transducer. The manifold pressure
can be read from the display through the TRANS SYS PRESSURE screen.
- Start and run the engine.
- Press the INCR or DECR key on the programmable instrumentation until TRANS OIL TEMP screen is reached.
NOTE: Screen order is set by the operator. The TRANS OIL TEMP and TRANS SYS PRESURE screens could or
could not be together depending on setup.
- Operate the engine at 1500 RPM until the transmission temperature displayed on the instrumentation reads at
least 49° C (120° F).
- Press the INCR as required to display the TRANS SYS PRESSURE screen.
- With the engine at 1500 RPM, record the transmission system pressure with all hydraulic systems OFF, PTO and
Diff Lock in the OFF position and the FWD switch in the ON position.
- Increase engine speed to 2000 RPM. Record the range powershift manifold pressure. Decrease engine speed.
• The Powershift System Manifold Pressure______________kPa at 2000 RPM
A. If the pressure reading is greater than 310 PSI (2240 kPa) go to the regulated system leakage test.
(Complete the regulated system leakage test before adjusting regulated pressure. See Hydraulic System
How It Works And Troubleshooting)
B. If the pressure reading is less than 310 PSI (2240 kPa) go to the regulated pump flow test (See Hydraulic
System How It Works And Troubleshooting)..
NOTE: Transducer Pressure Range: 2240 to 2250 kPa (325 to 355 PSI) at 2000 RPM and 120°F (49°C).
To convert kPa to bar, move the decimal place over two places to left, i.e. 2240 kPa equals 22.4 bar.
Fault codes will be generated if a problem is detected with the following components:
• System pressure transducer failure.
• Wire failed, or shorted between sensor and controller.
• Low regulated supply pressure to powershift valves.
• Low powershift manifold pressure due to leaking clutch.
• Wire failed, or shorted between powershift valve solenoid and controller.
