To select the correct thickness of cylinder head gasket Operation 3-13
Caution: If the correct piston height above or below the cylinder block is not obtained, damage to the engine
can occur. The difference between the highest and the lowest piston height must not exceed 0.1 mm.
1 Put the piston height tool (A) on the face of the cylinder block and rotate the gauge dial to the zero position.
2 Rotate the crankshaft until the piston crown is approximately at top dead centre (TDC).
3 Carefully put the tool over the top of the piston with the plunger of the gauge in contact with the piston above
the axis of the gudgeon pin.
4 Rotate the crankshaft to ensure that the piston is at the highest position and make a note of the gauge
indication.
Notes:
If the cylinder block, crankshaft, connecting rods or pistons are changed the piston height will have to be
checked and the correct thickness gasket used.
If the original piston is used, ensure that it is assembled to the correct connecting rod and is used in the
original cylinder.
