Install Cylinder Studs
NOTE: Do not reinstall or attempt to reuse any
cylinder studs that have been removed.
Discard any removed stud(s) and replace
with new.
If any of the cylinder studs were removed, install new
stud(s) as follows:
1. Identify the longer threaded end of the new stud
containing the Loctite
11-21.

Loctite Dri-Loc

2. Tighten two hex nuts together on the shorter
threaded section, with the identification mark on
the end.
3. Thread the end of the stud with the Loctite
the crankcase, until an exposed stud height of 75
mm (2 61/64 in.) is obtained. The end with the
dash mark must be out. See Figure 11-22. When
threading in the studs, use a steady tightening
motion, without interruption, until the proper
11.8
® Dri-Loc ® . See Figure
® into
height is obtained. The frictional heat from the
engaging threads may otherwise cause the
locking compound to set up prematurely.
Remove the two nuts.

4. Repeat steps 1-3 for each of the studs.
Install Reed and Breather Cover Assembly
1. Make sure sealing surfaces of the crankcase and
breather cover are clean and free of all old gasket
material. Clean with an aerosol type gasket
remover or cleaning solvent. DO NOT scrape the
surfaces as this can result in leakage.
2. Check to make sure there are no nicks or burrs on
the sealing surfaces.
3. Install the breather reed and breather reed
retainer onto the crankcase and secure with the
hex flange screw. Hold the assembly in line when
tightening. Torque the screw to 3.9 N·m
(35 in. lb.). See Figure 11-23.
