BRAKE ADJUSTMENT

Brake adjustment is required after installing new brake

pads or brake discs, after all repairs , and to improve

braking performance. Adjust the brakes when the brake

is cold. The park brake must be in the released

condition during the adjustment procedure.

1. Park the vehicle on a level surface. Block the

wheels to prevent the vehicle from moving. If it is

necessary to service the brake, use a jack to raise

the vehicle. Support the vehicle with safety  stands.

2. Apply 100 bar  (1450 psi) of hydraulic pressure to

release the parking brake.

3. Remove the screw cap.

4. Loosen the lock nut. Use a male hex wrench, M8 to

adjusting screw clockwise until both brake pads

contact the brake disc.

5. Turn the adjusting screw counterclockwise to set

the TOTAL clearance specified in the following

table.

6. Hold the adjusting screw in position. Tighten the

lock nut securely.

7. Install and hand-tighten the screw cap.

8. Actuate the brake several times.

3. Loosen the lock nut.

4. Use a male hex wrench M8, turn the adjusting

screw counterclockwise until the brake is released.

Emergency release requires approximately 40 Nm

(30 lb-ft) torque on the adjusting screw.

5. Tighten the lock nut. Install and hand-tighten the

AXLE

FRONT AXLE

Description

The rear axle is an Axle Tech axle is attached directly to

the frame with twelve M22 x 240 10.9 bolts. Weight of

the axle approximately 1150 Kg (2535 lb)

Removal

Park chassis on hard, level surface and block the rear

wheels.

Drain axle fluid into suitable container.

NOTE: Be prepard to collect and contain all fluids in an

approved container.

Place jacks under the machine and raise the frame until

the weight is off the rear wheels. Install jack stands to

securely support the machine frame.

IMPORTANT: Make sure the jack stands are rated for

supporting the weight of the machine.

Remove the wheels from the front axle.

FIG. 1: Place an alignment mark on the slide yoke in

the event the slide yoke should come apart. Remove

the four bolts (1) that mount the front driveline assembly

(2) to the front axle. Disconnect the rear drive shaft

assembly

Using a suitable lifting device support the axle (3).

Loosen and remove the twelve nuts with washer that

secure the axle. Remove the twelve M22 x 240 10.9

bolts (4) and carefully remove the axle.

Installation

Make sure the machine is adequately supporteed with

jackstands.

IMPORTANT: Make sure the jack stands are rated for

supporting the weight of the machine.

Position the axle (3) unter the machine. Raise the axle

and mount to the frame with twelve M22 x240 10.9

bolts (4) and fasten with eight nuts with washers.

IMPORTANT: Always use new nuts, or use Loctite

242-41.

Install the wheels to the axle.

Once the machine has been lowered to the ground and

the full weight applied to the wheels a final tightening

will be necessary. Tighten the twelve bolts in even

increments to 515 Nm (380 lbf - ft)

IMPORTANT: Check the bolt torque daily for the next

50 hours of operation and every 500 thereafter.

Install the front drive shaft (2) assembly to the front

axle. Mount the driveline with four bolts (1). Torque

bolts to 215 Nm (158 lbf - ft).
