TEST NO. 2: Traction Circuit System Relief Pressure
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately 10
minutes.
2. Before doing traction pressure test:
A. Drive machine to an open area, lower cutting
units, turn the engine off and engage the parking
brake.
B. If testing forward function, connect a chain to the
rear frame tie-down brackets. Connect the other end
of the chain to an immovable object and remove all
slack from the chain. If testing reverse function, at-
tach chain to the center of the front frame member
(Fig. 15).
Note:
On 4WD models, the driveshaft and driveshaft
bearing support must be removed to access the reverse
test port.
CAUTION
Prevent personal injury and/or damage to equip-
ment. Read all WARNINGS, CAUTIONS, and Pre-
cautions for Hydraulic Testing at the beginning
of this section.
Note:
Test ports are 7/16-20 SAE O-ring ports.
3. Connect a 5,000 psi (350 Bar) gauge to traction cir-
cuit test port for function to be checked (Fig. 15).
4. Start the engine and move throttle to full speed (3200
RPM).
5. Sit on seat, and with brakes engaged, slowly de-
press the top of traction pedal. While pushing top of trac-
tion pedal down, look at pressure reading on gauge.
GAUGE READING:
Forward: 3450 to 3750 PSI (237.9 to 258.6 bar)
Reverse: 2600 to 2900 PSI (179.3 to 200 bar)
6. If traction pressure is too low, inspect check/high
pressure relief valves.
Note:
Clean or replace valves as necessary. These
cartridge type valves are factory set, and are not adjust-
able. If check/relief valves are in good condition, replace
or overhaul transmission.
Note:
The forward and reverse check/high pressure
relief valves are different. One valve cartridge has a ma-
chined groove on seating surface and must be installed
in the ”reverse” port (see Check and High Pressure Re-
lief Valves in Transmission Repairs section).
