3208 – Finding Top Center Compression Position For No.1 Piston

No. 1 piston at top center (TC) on the compression stroke is the starting point for all timing procedures.


Fitting And Bolt Location
(1) Fitting. (2) Bolt.


Installing Bolt
(2) Bolt. (3) Timing hole.

1. Remove fitting (1) from the timing hole (3) in the front cover. Put bolt (2) in timing hole (3).

2. Turn the crankshaft Counterclockwise (as seen from rear of engine) until bolt (2) will go into the hole in the drive gear for the camshaft.

3. Remove the valve cover on the right side of the engine (as seen from rear of engine). The two valves at the right front of the engine are the inlet and exhaust valves for No.1 cylinder.

4. The inlet and exhaust valves for No.1 cylinder must now be closed and the timing pointer will be in alignment with the TC-1 on the damper assembly. The No.1 piston is now at top center on the compression stroke.
