CYLINDER HONE
SELECTION/HONING
PROCEDURE
A hone which will straighten as well as remove
removed
material from the cylinder is very important. Using a
common spring loaded glaze breaker for honing is not
where
advised for nicasil cylinders. Polaris recommends
using a rigid hone or arbor honing machine.
Cylinders may be wet or dry honed depending upon
the hone manufacturer's recommendations.
honing removes more material faster and leaves a
more distinct pattern in the bore.

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

IMPORTANT: Clean 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. Use
electrical contact cleaner if necessary to clean these
areas. Rinse thoroughly, dry with compressed air,
and oil the bore immediately with Polaris 4 Cycle
Lubricant to prevent the formation of surface rust.
CAUTION:
according to
G
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.
G Release the hone at regular intervals
and inspect the bore to determine if
it has been sufficiently deglazed, and
to check for correct cross--hatch.
NOTE: Do not allow cylinder to
heat up during honing.
G
After honing has been completed,
inspect cylinder for thinning or
peeling.
