### ADJUSTING REAR SHIMMING

Unlike the front mounting, the rear can only be dismantled completely after stripping the primary transmission as described in Section C13 and C14.The shims can, however, be changed at the right side only without the need for this further work. The normal method of shimming, after the clearance has been checked following Section F14, is:
1 | Remove the self-locking nut and washer from the right end of the main mounting stud.
2 | Using a soft metal drift drive the mounting stud partially through, right to left until it protrudes some 4 in. from the left hand side.

3 | Slide the right gaiter lip off the mounting tube then push down and rearwards clear of the frame the gaiter, spacing collar and polyurethane washer as a group.
4 | Collect the right side shims and end cap. Examine the polyurethane washer tor excessive wear and replace if necessary.
As with the front mounting, the thickness of shims required should be determined from the measurement at the time of stripping as against the ideal clearance 0.010 in. (0.025 mm). For example, to correct a clearance of 0.030 in., a single 0.020 in. shim would need to be added. Reassemble as follows:
5 | Clean and grease lightly the parts of the right end cap/gaiter group, using a silicone grease such as Releasil No. 7.
