1. Counterbore the damaged area until the fretting, corrosion, cracks, or worn step on top of the block under the liner flange is removed.
2. Measure the depth of the counterbore and select the next thickest shim. Use only ONE new shim per cylinder. Do NOT reuse an old shim or stack of shims.
3. Continue machining the counterbore to a depth that will adjust the liner projection to the height of the other cylinders.
4. If all of the cylinders are counterbored, adjust the liner projection to the projection shown in the Service Manual.
