Note:
Before disassembly, carefully clean the surface of the parts.

ble.

Clean the parts with nylon or soft paper.
Before checking or assembling, clean all the parts with liquid care-

fully.

You'd better apply a layer of transmission lubricant on the surface of

the parts before assembly. Apply a layer of vaseline on the surface of
hydraulic pressure parts and O-type oil seal.

Replaceall of the oil seal, spacer and O-ring. Avoid using the used

spacer, oil seal and O-ring when assembling. After assembly, you must
have a test run.

Check

Check the free travel of the steering wheel

Measure the free travel of the steering wheel when it is set on the cen-

ter.

                   Free travel                  ≤ 35mm

If the measured value isn't in this range, check the the steering gear

clearance and the ball pin.

Check the center position of the steering wheel

Correct the center position of the steering wheel before dismantling. 

Check

When the vehicle is running straight, check to see if the steering

wheel is in the center position.

If not, disassemble the steering wheel and reassemble it.

Check the turning angle of the front wheel

Turn the steering wheel left and right to measure its maximum turn-

ing angle.

        Inner wheel                           38.5°± 30'

       Outer wheel                           29.5°
