The front plate will have to be countersunk as shown "X" to take the screws CMZ407MS, which replace the existing hexagon-headed screws, which would foul on the timing chain. Check for clearance on chain all round and align gears as per Workshop Manual.

When using A plus timing covers there is a small round pressing at the bottom which needs making flat to allow timing chain clearance.

Ensure that the crankshaft oil thrower 12A1148 is correctly fitted with the letter F. Facing you or on very early engines the lip faces outwards.
