Figure 325 — Flywheel Marks
There are 12 clutch mounting bolt holes in the
flywheel, but only 8 of these holes are used to
mount the clutch. Every third bolt hole, for a total
of four, is not used. These holes are in an open
area between the clutch mounting flanges. The
unused holes are easy to see through the timing
access hole in the flywheel housing. The bolt
holes where there are clutch mounting bolts are
more difficult to see because the clutch mounting
bolt head is somewhat rearward of the timing
access opening. To aid in counting the clutch
mounting bolt/bolt holes, keep in mind that there
is slightly over four inches between one bolt hole
and the next. Locating the clutch mounting bolts
may be made easier by removing the bell housing
inspection cover and viewing or feeling for the
bolts through the access hole.
After verifying that there is a clutch mounting bolt/
bolt hole in line with the TC mark, the next step is
to find the three locations where the valve
adjustment marks should be. Put a temporary
mark (chalk, grease pencil, paint, etc.) at each of
the three locations. Proceed as follows:
1. Beginning with the TC mark aligned with the
timing pointer, rotate the engine in the
direction of normal rotation
(counterclockwise, viewed from rear) to the
next clutch mounting bolt/bolt hole.
Temporarily mark this location for cylinders
1 and 6.
2. Continue rotating the engine in the normal
direction and count the clutch mounting bolt/
bolt holes as they pass the timing access
opening. At the fourth mounting bolt/bolt
hole, make a temporary mark on the
flywheel for cylinders 2 and 5.
3. Rotate the engine another four mounting
bolt/bolt holes and make a temporary mark
on the flywheel for cylinders 3 and 4.
4. Rotate the engine another three clutch
mounting bolt/bolt holes and verify that the
flywheel is at the TC mark. Then, rotate the
engine one more bolt/bolt hole and verify
that the flywheel is at the temporary mark
made for cylinders 1 and 6.
