Hold the steering wheel with both hands and try to move it from one side to the other. Is the maximum allowed movement in the steering column not exceeding 25 mm (1.0 inch)?

If the value is not within the limit, perform the following steps:

Inspect the pivot joint for loose bolts and tighten them if necessary. Did you apply 9S-3263 Thread Lock Compound to the bolts before tightening?

Inspect the pivot joint for excessive wear. Is there excessive wear?

Did you replace the bushings if there was excessive wear?

WARNING: Failure to perform this inspection and repair may cause loss of steering control, which may result in personal injury or death. Do not operate the machine until the inspection and repair are completed.
