Brake Valve Pressure Check and Adjustment

All except installations with 2 speed control

Test Equipment:

•

(2) 1,000 psi (6,895 kPa) Gauges

Connect pressure gauges to test ports:

• X1
• TP-BRAKE

(or

TP-BR)

Instructions

1. With the engine shut off, connect a 1000 psi pressure

gauge to the

TP-BRAKE (or TP-BR)

pressure test

port and one 1000 psi pressure gauge to the

X1

pressure test port on the control manifold.

2. Start dozer and set to high-free idle.

3. Slowly meter the control lever into the

LINE-IN

position while monitoring both gauges.

4. TP-BRAKE

pressure will jump to full pilot supply

pressure when

X1

reaches the pilot setting of the

brake valve.

5. Check pressure as indicated in Table 3-4. The brake

valve sets the overlap between the hydraulic motor
drive and brake release.

6. A low setting on the brake release valve will release

the brake before the motor begins driving. A high
setting on the brake release valve will momentarily
drive the motor against the brake before the brake
releases.

Brake Valve Adjustment

1. Slowly meter the control lever into the

LINE-IN

position.

2. Measure pressure at

TP-BRAKE

and

XI

pressure

test ports.

3. Loosen brake valve locknut. Turn adjusting capscrew

OUT to decrease pressure and IN to increase
pressure. Adjust pressures as shown in Table 3-4.

NOTICE

The values in Table 3-4 are based on
information available at time of publishing.
Refer to the service/maintenance manual
supplied with your dozer to verify the
available pilot pressure.
