Cleaning and Inspection
Cylinder Block and Crankcase Cover
IMPORTANT: The crankcase cover and cylinder block are a matched, line‑bored assembly and must never mate with a different
crankcase cover or cylinder block.

IMPORTANT: To prevent damage to components, remove all hoses, check valves, and other oil system components before
submerging the cylinder block in cleaning solution.
1. Thoroughly clean the cylinder block and crankcase cover. Ensure that all sealant and old gaskets are removed from matching
surfaces. Ensure that carbon deposits are removed from exhaust ports.
2. Inspect the cylinder block and crankcase cover for cracks or fractures.
3. Check the gasket surfaces for nicks, deep grooves, cracks, or distortion that could cause compression leakage.
4. Check all water and oil passages in the cylinder block and crankcase cover to ensure that they are not obstructed and that
the plugs are in place and tight.
Special Service Information
Grooves in the Cylinder Block Caused by Crankshaft Sealing Rings
Grooves in the cylinder block caused by crankshaft sealing rings are not a problem, unless installing a new crankshaft, and the
new sealing rings do not line up with the existing grooves in the cylinder block. If installing a new crankshaft, refer to
Crankshaft
Installation
to determine if the powerhead can be used.
Cylinder Bores
Inspect cylinder bores for scoring, scuffing, or aluminum transfer. Minor scoring or scuffing can be removed by honing. If aluminum
transfer has occurred, muriatic acid can be applied where the transfer of aluminum has occurred. Flush the cylinder bore with
water to remove any remaining acid.
Honing Procedure
1. Follow the hone manufacturer's recommendations for use of the hone and lubrication during the honing process.
2. A continuous flow of honing oil should be pumped into the work area.
IMPORTANT: Incorrect or excessive honing may damage the cylinder bores, leading to engine failure. Follow the hone
manufacturer's instructions. Measure the cylinder diameter often.
3. Start stroking at the smallest diameter. Maintain firm stone pressure against the cylinder wall to assure fast stock removal
and accurate results.
