Honing To Deglaze; Cleaning The Cylinder After Honing - Polaris Sportsman 800 EFI 4x4 2012 Service Manual

Honing To Deglaze

A finished cylinder should have a cross-hatch pattern to
ensure piston ring seating and to aid in the retention of
the fuel/oil mixture during initial break in. Hone cylinder
according to hone manufacturer's instructions, or these
guidelines:
• Honing should be done with a diamond hone.
Cylinder could be damaged if the hone is not hard
enough to scratch the nicasil lining.
• Use a motor speed of approximately 300-500
RPM, run the hone in and out of the cylinder
rapidly until cutting tension decreases. Remember
to keep the hone drive shaft centered (or cylinder
centered on arbor) and to bring the stones
approximately 1/2, (1.3 cm) above and below the
bore at the end of each stroke.
• Release the hone at regular intervals and inspect
the bore to determine if it has been sufficiently de-
glazed, and to check for correct cross-hatch.
NOTE: Do not allow cylinder to heat up during
honing.
• After honing has been completed, inspect cylinder
for thinning or peeling.
If cylinder wear or damage is excessive, it will be
necessary to replace the cylinder. The cylinders are lined
with a nicasil coating and are not repairable. Hone only
enough to de-glaze the outer layer of the cylinder bore.
IMPORTANT: Clean the cylinder after honing
If cylinder wear or damage is excessive, it will be
necessary to replace the cylinder. The cylinders are lined
with a nicasil coating and are not repairable. Hone only
enough to de-glaze the outer layer of the cylinder bore.

Cleaning the Cylinder After Honing

It is very important that the cylinder be thoroughly
cleaned after honing to remove all grit material. Wash the
cylinder in a solvent, then in hot, soapy water. Pay close
attention to areas where the cylinder sleeve meets the
aluminum casting. Use electrical contact cleaner if
necessary to clean these areas. Rinse thoroughly, dry
with compressed air, and oil the bore immediately with
Polaris Lubricant.
