4-cylinder Timing Gears

Leyland Workshop Manual image, white arrows showing the positions of the keyways and black arrows showing the position of the dimples.

Haynes Manual image, rotated for comparison with the Leyland image, black arrows showing the position of the key-ways and white arrows showing the position of the dimples.

Both images show the correct orientation of shafts and gears in preparation for fitting the chain and gears to the shafts. Note that this installs the cam such that No.4 piston is at TDC on its compression stroke, not No.1 piston.

To install the distributor drive dog correctly, using the instructions contained within the manuals which state that No.1 piston must be at TDC on its compression stroke, the crank must be turned one full turn i.e. 360 degrees. This puts the camshaft keyway adjacent to the crank gear, and the cam gear dimple at top-right.
