13 To check the piston height above the cylinder block
New 1000 Series 13-4
Special tools: Piston height tool, PD.41D Dial gauge for use with PD.41D, PD.208 Caution: If the correct piston height above the cylinder block is not obtained, damage to the engine can occur. Put the piston height tool (A) on the face of the cylinder block and rotate the gauge dial to the zero position. Rotate the crankshaft until the piston crown is approximately at top dead centre (TDC). 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. Rotate the crankshaft to ensure that the piston is at the highest position and make a note of the gauge indication.

If the original piston is used, ensure that it is assembled to the correct connecting rod and is used in the original cylinder.
If any of the components listed below are renewed, refer to the relevant operation: !
The connecting rod, see operation 13-7.
