Our adjustment procedure…

1. Undo the adjuster locknut and wind out the adjuster (anticlockwise) until it is completely free from the end of the lockbar.

2. Insert the new kingpin (or connect to a trailer) and ensure the mechanism fully closes.

3. Screw the adjuster clockwise until it touches the end of the lockbar.

4. Screw inwards a further 3 complete turns (to give 0.4mm running clearance).

5. Tighten the adjuster locknut.

6. Remove the kingpin/test unit

Adjustment should be checked every 6 months or 50,000 km

If the jaw is less than 20.25mm from the kingpin diameter to the flat face that meets the lockbar then a new jaw kit is required.

This is generally due to no adjustment on the lockbar for kingpin clearance or the adjuster stud is missing altogether. To fix this, carryout the adjustment procedure (see previous FAQ or refer to the the product manual) or if required – fit a new adjuster stud.
