Engine timing
To check Operation 8-2
Special requirements
If it becomes necessary to check the valve/ignition timing position of the engine, use this procedure:
1 With the engine switched off and electrically isolated, remove the rocker cover, Operation 3-1.
2 Remove the top bolt (A1), the timing bolt, from the cover (A2) on the flywheel housing and slacken the other
cover bolt to allow the cover to open.
Caution: If a customer-fitted speed sensor is fitted to the flywheel housing, it must be removed before the
engine turning tool can be inserted.
3 Remove the plug (A3) from the timing bolt location in the flywheel housing and fit the timing bolt.
4 Insert the engine turning tool, CH11148, into the flywheel housing through the aperture behind the cover
(A2). Use a
1
/
2
inch drive ratchet with the turning tool to rotate the engine flywheel in the normal direction of
rotation (anti-clockwise when viewed on the flywheel) until the timing bolt engages with the threaded hole in
the flywheel. The piston of number 1 cylinder is now at TDC (top dead centre).
