ENGINE / COOLING SYSTEM

SETTING TDC (TOP-DEAD-CENTER)
To ensure the piston is at TDC. Remove the outer clutch
cover to access the drive clutch to aid in engine rotation
(manually turn the drive clutch counter clockwise).

1. With the CPS sensor removed, rotate the engine
until the “<” marked on the flywheel q is aligned with
the CPS mounting hole. This will set TDC, but not
necessarily TDC of the compression stroke.

2. View the timing marks on the camshaft sprockets to
ensure the engine is at TDC on the compression
stroke
NOTE
Intake cam sprocket should have “I” marks aligned with
gasket surface and the exhaust cam sprocket should
have “E” marks aligned with gasket surface.

3. See Camshaft Timing - Quick Reference, page 3.67
for additional information.
