Locknut (Adjusting Cover), Adjusting Cover Disassembly Note

1. Install two nuts to the bolt across a flat 24 mm

{0.94 in} and tighten them using a wrench.

2. Secure the adjusting cover with the bolt and nuts

created in Step 1, and remove the locknut using
the SST.

Caution

• If a tool such as a torque wrench is

installed to the SST (49 E032 308), install
the tool so that it is perpendicular to the
SST as shown in the figure. If the tool is
not installed as instructed, the SST can
separate from the locknut easily which
could cause damage to the locknut while
doing the work.

3. Using the bolt/nut produced in Step 1, remove the

adjusting cover.
