Piston and cylinder dimensions





Piston projection of all pistons at TDC must be measured when installing new pistons or a short engine. Depending upon piston projection, install the corresponding cylinder head gasket according to the following table:

Note: Turn engine clockwise to measure piston projection at TDC.

Piston Projection Gasket Identification Holes/Notches
0.91 mm - 1.00 mm 1
1.01 mm - 1.10 mm 2
1.11 mm - 1.20 mm 3






Cylinder head gasket identification
^ Part No. = - arrow 1 -
^ Production control code arrow 2 - (can be disregarded)
^ Holes = - arrow 3 -

Note: If different values are measured during the projection measurement, use the largest dimension for determining the gasket.
