198-4240     Digital Pressure Indicator     1    Note: Make sure that the filters and the screens are clean before you test any pressures. Make sure that the oil is at operating temperature before you perform this test.
Personal injury or death can result from sudden machine movement.Sudden movement of the machine or release of air pressure or oil pressure can cause injury to persons on or near the machine.To help prevent possible injury before testing and adjusting any air system or hydraulic system, perform the procedure in the Testing and Adjusting, "General Information" section.
This test will show the following conditions if the conditions exist:
The transmission charging pump section is good.
The relief valve of the selector and pressure control valve is correctly set.Procedure

(K) Pressure tap for the charging pressure of the transmission
Connect 198-4240 Digital Pressure Indicator to the nipple at pressure tap (K) .
Start the engine while the parking brakes are engaged. Run the engine at the low idle rpm with the transmission in NEUTRAL-1. The pressure on the gauge should be a minimum of 2480 kPa (360 psi).
Run the engine at the high idle rpm with the transmission in NEUTRAL-1. The maximum pressure on the gauge should be 3200 kPa (465 psi).
When this test is complete, stop the engine and remove the test equipment.Problem: The oil pressure is too low at low idle and the oil pressure is too low at high idle.
Probable Cause
Failure of the transmission charging pump section
There are bad seals in a clutch of the transmission. Refer to Testing and Adjusting, "Transmission Hydraulic Control Clutch Pressure - Test".Problem: The oil pressure is too low at low idle and the oil pressure is correct at high idle.

( 1 ) Before an adjustment is made, be certain that the valve spring is not weak or broken.Probable Cause
The setting of relief valve (1) is too low. Add spacers (2). Refer to Table 2. Adjust the relief valve to the low idle setting.
There are bad seals in a clutch of the transmission. Refer to Testing and Adjusting, "Transmission Hydraulic Control Clutch Pressure - Test".Problem: The oil pressure is too high.
Probable CauseThe setting of relief valve (1) is too high. Remove spacers (2). Refer to Table 2. Adjust the relief valve to the low idle setting.
