NOTE
When the front cylinder is set to TDC
on the compression stroke, the timing
mark on the cam sprocket plate may
not precisely align with the pointer on
the cylinder head. On some models,
the camshafts are slightly retarded.
The mark could be off by as much as
1. Rear chain guide
2. Chain guide bolt
3. Cam chain drive
assembly
4. Cam chain
5. Front chain guide
6. Retainer bolt
7. Shaft retainer
8. Drive assembly

1/2 tooth. Before removing the primary
drive gear, set the front cylinder to top
dead center on the compression stroke,
and note the position of the timing
marks on the cam sprocket plate and
cylinder head. Take a photograph or
make a drawing so the camshaft can
be correctly timed during assembly.
Also note that the timing mark on the
timing gear (A, Figure 48), the mark
on the cam chain drive assembly (B)
and the center of the drive assembly
shaft (C) align when the front cylinder
is at TDC.
Refer to Figure 49.
