Start engine and move travel and range select
lever into 3rd gear, forward or reverse (F3, R3)
Slowly increase engine
throttle. Maintain speed until transmission oil
temperature reaches operating range of 180 to
250 degrees F (82 to 121 C).
If engine operates at low rpm, check engine for
malfunctions. If engine operates at proper rpm,
proceed with mechanical test.
B. MECHANICAL TEST
Release hood assembly (1) by lifting handle (2).
Open hood assembly.

Check that radiator is clean and free from
All test measurements are to be made
after engine has reached normal
temperature must be 180 to 220
degrees F (82 to 104 C).
Place transmission in neutral.
Use STE/ICE tester to determine
Connect pressure gauge to transmission port D.
Measure operating pressure. Minimum pressure
shall be 60 psi (414 kPa) at 2000 rpm engine
speed. Maximum pressure shall be 120 psi (827
kPa) at no-load governed speed (2725 rpm).
Move pressure gauge to port A. Measure
regulated clutch pressure. Normal operating
pressure shall be 240 to 280 psi (1655 to 1930
kPa) at 2000 rpm engine speed.
