Removal
CAUTION:Since the engine is not free-wheeling, the timing procedures must be followed exactly or piston and valve damage can occur.

Remove the engine front cover. Refer to ENGINE FRONT COVER .
Remove the crankshaft sensor ring from the crankshaft.

Install the Camshaft Positioning Tool.
NOTE:Slightly loosen the camshaft holding tools to allow slight camshaft movement.

Pre-position the camshafts.
Rotate the LH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 12 o'clock.
Rotate the RH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 11 o'clock.
Tighten the Camshaft Holding Tools to maintain camshaft pre-positioning.
CAUTION:Unless otherwise instructed, at no time when the timing chains are removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur.

CAUTION:Rotate the crankshaft counterclockwise only. Do not rotate past position shown or severe piston and valve damage can occur.

NOTE:The number one cylinder is at top dead center (TDC) when the stud on the engine block fits into the slot in the handle of the special tool.

Position the crankshaft so the number one cylinder is at TDC with the special tool.
Remove the Crankshaft Holding Tool.
Install the crankshaft sprocket, make sure the flange faces forward.
