STEERING WHEEL FREE PLAY CHECK

1. With the engine running (hydraulic operation), set

the front wheels straight ahead.

ACX01122 AB

2. Measure the play on the steering wheel

circumference before the wheels start to move
when slightly moving the steering wheel in both
directions.

Limit: 30 mm

3. When the play exceeds the limit, check for the

play on the steering shaft and steering linkage
connection. Correct or replace.

4. If the free play still exceeds the limit value, set the

steering wheel straight ahead with the engine
stopped. Load 5 N towards the steering wheel
circumference and check the play.

Standard value (steering wheel play with the
engine stopped): 10 mm or less
