Figure 12 - Location of the Jaw pin
NOTE
The jaw pin (see Figure 12) is only a pivot pin and is designed to
be smaller than the hole in the jaw. This clearance enables the
jaw to fully contact the kingpin and lockbar at all times.
Adjustment Procedure
1. Undo the adjuster locknut and wind out the adjuster (anti-
clockwise) until it is completely free from the end of the lockbar.
2. Insert the new kingpin (or kingpin test unit part no 59004124)
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 0.525mm
running clearance).
5. Tighten the adjuster locknut.
6. Remove the kingpin/test unit
Replacement of Worn Parts
If the jaw is undersized (dimension A in Figure 12) is less than
20.25mm) a new jaw kit is required.
For precise fitting instructions, please contact Fontaine
International.
IMPORTANT
After fitting the new jaw kit, the mechanism must be re-adjusted
to allow correct running clearance around the kingpin.
A complete jaw kit MUST ALWAYS be fitted to ensure the jaw and
lockbar are correctly matched.
