Timing Hole location (Typical Example) (1) Timing hole plug (not shown) (2) Flywheel housing
Illustration 2 g00700256
Right Side Location (1) Timing hole plug (2) Flywheel housing
Illustration 3 g00700258
Left Side Location (1) Timing hole plug (2) Flywheel housingNote: The timing hole plug (1) can be in one of two positions:
The right front face of the flywheel housing (Illustration 2)
the left front face of the flywheel housing (Illustration 3)
Remove timing hole plug (1) that is located on the front side of flywheel housing (2) .Note: Turn the engine with the four large bolts on the front of the crankshaft. Do not use the eight small bolts on the front of the crankshaft pulley.
Put the timing bolt through the timing hole in the flywheel housing (2) .Turn the flywheel in the direction of normal engine rotation. Turn the flywheel until the timing bolt engages with the hole in the flywheel.Note: If the flywheel is turned beyond the point of engagement, the flywheel must be turned in the direction that is opposite of normal engine rotation. Turn the flywheel by approximately 30 degrees. Then turn the flywheel in the direction of normal engine rotation until the timing bolt engages with the threaded hole. When the No. 1 piston is at the top center position, this procedure will remove the play from the gears.
Remove the valve cover.The inlet valves and the exhaust valve for the No. 1 cylinder are fully closed under two conditions:
No. 1 piston is on the compression stroke.
The rocker arms can be moved by hand.If the rocker arms cannot be moved and the valves are slightly open, the No. 1 piston is on the exhaust stroke. Note: Refer to Testing And Adjusting, "Crankshaft Positions for Valve Lash Setting".
After the timing bolt has been installed in the flywheel, complete these procedures, as required:
Find the cylinders that need to be checked for the stroke position of the crankshaft.
Find the cylinders that need to be adjusted for the stroke position of the crankshaft.
When the actual stroke position is identified and the other stroke position is needed, remove the timing bolt from the flywheel.
Turn the flywheel by 360 degrees in the direction of normal engine rotation.Note: The timing bolt hole is used for the following procedures only:
adjustment of the fuel timing dimension
valve lash setting
