times to distribute lubricant over full length
of shaft. Be careful that lubricant does not get on
inner halves of pulley.

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 tightening chaincase retaining screws.
Make sure to install alignment shims as noted at
removal.
CAUTION : Bleed oil injection pump on
models that have had their injection oil
supply line removed. Refer to INJECTION OIL

ADJUSTMENT
10,11, Shim
NOTE : The following adjustment must be
performed 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.

Spring Torsional Pre-Load
To check spring pre-load adjustment, use spring
scale hook (P / N 529 0065 00) and a spring scale.
Install the hook on the sliding half, making sure
the spring scale is perpendicular to the pulley axle.
