2 If play is excessive in the worm screw rollers, screw up the lower adjuster ring 4 (see FIG 9:4). Once adjustment has been completed the adjuster ring must be secured by the cotter. The ring should be positioned so that the hole in the steering box lines up with one of the spaces between the ring castellations.
3 Should the meshing between the worm screw and the sector not be at the correct central position this condition may be rectified by moving the sector axially. To do this add or remove shims (see FIG 9:5) below the thrust ring of the worm sector. The final adjustment must be carried out by using the adjustment screw 1 (see FIG 9:5) on the cover and then locking the screw by nuts 2. In service shims are supplied .0039 inch thick.
The above described adjustments must eliminate any play and back lash in the steering gear without rendering the steering gear stiff to operate between the two locks.
4 During adjustment should any seal be found to be damaged then it should be renewed.
