INSTALLATION PROCEDURE 2
IMPORTANT: Rotate the number 1 cylinder to top dead center (TDC) of the compression stroke. The engine front cover has 2 alignment tabs and
the crankshaft balancer has 2 alignment marks (spaced 90 degrees apart) which are used for positioning the number 1 piston at TDC. With the piston
on the compression stroke and at TDC, the crankshaft balancer alignment mark (1) must align with the engine front cover tab (2) and the crankshaft
balancer alignment mark (4) must align with the engine front cover tab (3).
1. Rotate the crankshaft balancer clockwise until the alignment marks on the crankshaft balancer are aligned with the tabs on the engine front cover
and the number 1 piston is at TDC of the compression stroke.
