ENGINE / COOLING SYSTEM
CYLINDER HONE SELECTION / HONING
PROCEDURE
CAUTION
Selecting a hone which will straighten as well as
remove material from the cylinder is very important.
Using a common spring loaded finger type glaze
breaker for honing is never advised. Polaris
recommends using a rigid hone or arbor honing
machine which also has the capability of oversizing.
Cylinders may be wet or dry honed depending upon the
hone manufacturer's recommendations. Wet honing
removes more material faster and leaves a more distinct
pattern in the 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
engine oil.
