Loosen bolt (5) until dial indicator (6) can be moved. Place gauge body (7) and dial indicator (6) on the long side of gauge.
Slide dial indicator (6) into the correct position. When the point of the dial indicator contacts gauge block (8) , the dial indicator is in the correct position. Slide the dial indicator until the needle of the gauge makes a quarter of a revolution clockwise. The needle should be in a vertical position. Tighten bolt (5) and zero the dial indicator.

If a liner does not meet the recommended cylinder liner projection specification, check the following parts:
The depth of the cylinder block bore should be 100.00 0.03 mm (3.937 0.001 inch).
The liner flange should be 100.12 0.03 mm (3.942 0.001 inch).If the dimensions for the liner flange do not match the specifications, replace the liner. Then repeat the liner projection measurements. If the dimensions for the depth of the cylinder block bore do not match the specifications, replace the cylinder block. Then repeat the liner projection measurements. C15 Through C18 Procedure
