Thoroughly clean the fixed half shaft. Remove
rust with no. 320 grit sand paper.
Apply a light film of anti-seize lubricant (P/N 413
7010 00) on the shaft. Always wipe off surplus.
NOTE: Activate the sliding half several times to
distribute lubricant over full length of shaft. Be
careful that lubricant does not get on inner halves
of pulley.
13,14, Brake Disc and Screw
Install brake disc on fixed half and torque screws
to 13 N•m (115 lbf•
in ).
Assemble driven pulley components by reversing
the disassembly procedure.

One of its ramps facing upwards, hold sliding half
with welding clamps. Install spring into sliding half
at its original setting (previously noted adjusting
hole). Insert other spring end in outer cam and
turn clockwise until a slider shoe corresponds
with the ramp facing upwards. Push cam all the
way in then install roll pin coated with anti-seize
lubricant (P/N 413 7010 00).
TYPICAL

2. Welding clamp
INSTALLATION
Driven Pulley and Chaincase
Install a new upper chaincase oil seal and a new
chaincase cover seal.
Reinstall the driven pulley on vehicle by reversing
the removal procedure.
NOTE: If chaincase screws have been slackened,
chaincase can be reinstalled to its initial position
by securing driven pulley support before tighten-
ing chaincase retaining screws. Make sure to in-
stall alignment shims as noted at removal.
ADJUSTMENT
10,11, Shim
NOTE: The following adjustment must be per-
formed with a new drive belt.
For best performance, particularly at starting, top
of drive belt should be flush with top of driven pul-
ley halves.
TYPICAL
1. Belt flush with the top of the pulley halves
Shim(s) no. 10 and no. 11 provide belt height ad-
justment between pulley halves. Adding shims
will lower the belt in driven pulley, while removing
shims will raise the belt. Adjust properly.
5, Spring
General
It is usual to experience spring setting during
breaking period of a new spring. The factory
spring preload is slightly higher (about 1 kg (2 lb))
to compensate for spring setting. Specifications
in TECHNICAL DATA 10 are applicable after break-
in period (about 10 hours of use).
