Machine The Liner Seat
Continue to raise the bottom depth set collar until the top depth set collar is touched.Note: To ensure a smooth machined finish, make the final cut 0.03 mm (0.001 inch).
Never rotate the cutter plate in the counterclockwise direction or the cutter bit will be damaged.
Retract the cutter bit.
Loosen the cutter bit locking screw.
Turn the cutter bit adjusting screw clockwise until the cutter bit is fully retracted into the cutter plate.
Remove the four mounting bolts and remove the counterbore tool.

Measure The Depth Of The Newly Machined Bore
Verify the depth of the bore. The number of shims will be determined by using Table 2.
Select the appropriate liner shims.
Use Table 2 to select shims that make the counterbore depth equal to original 100 mm .03 mm (3.94 in 0.001 in) depth. Shims can be stacked as needed.

Install Shims
Install the proper shims into the counterbore. Shims may need a slight twist to help fit into the counterbore.
Remeasure the depth of the counterbore and verify that depth is within the 100 mm .03 mm (3.94 in 0.001 in) specification. If not, remachine the depth or add additional shims.
Make sure that all the shims are properly centered before installing the liner. The bumps on the outside of the shims are designed to help center the shim in the bore.
