The following procedure must be used to torque the
cylinder head properly:
Cam Chain/Camshaft Installation
Install the cam chain over the crankshaft with the
plated links facing outward.
CAUTION: Serious engine damage may re-
sult if the camshaft is not properly timed to
the crankshaft.
IMPORTANT CAMSHAFT TIMING NOTE:
In order to
time the camshaft to the crankshaft, the piston must be
precisely located at Top Dead Center (TOC). This can
be accomplished using one of two methods.
When the stator assembly is removed, follow the pro-
cedure outlined in Method 1. This method uses the
cam chain plated links to time the camshaft and the dot
on the cam chain drive sprocket to establish TOC (see
Method 1, page 3.83). It is important to note that this
method can only be used when the stator is removed
and the cam chain drive sprocket is in view. The plated
links are not used to time the camshaft when the fly-
wheel is installed.
When the stator assembly is installed use Method 2.
This method establishes accurate Top Dead Center
(TOC) by aligning the single mark on the flywheel with
the notch in the timing inspection hole (see Method 2,
page 3.85). The camshaft sprocket alignment pin
faces upward and directly in line with the crankshaft to
camshaft centerline.
