Servicing Top-Side Components - Arctic Cat ROV 2013 Service Manual

CAUTION
When removing the cylinder, be sure to support the pis-
ton to prevent damage to the crankcase and piston.
13. Using an awl, remove the piston-pin circlips.
14. Using the Piston Pin Puller, remove the piston pin;
remove the piston.
NOTE: It is advisable to remove the opposite-side
circlip prior to using the puller.
NOTE: Support the connecting rod with rubber
bands to avoid damaging the rod or install a suit-
able connecting rod holder.
CAUTION
Do not allow the connecting rod to go down inside the
crankcase. If the rod is down inside the crankcase and
the crankshaft is rotated, severe damage will result.

Servicing Top-Side
NOTE: Whenever a part is worn excessively, cracked,
or damaged in any way, replacement is necessary.
VALVE ASSEMBLY
When servicing valve assembly, inspect valve seats,
valve stems, valve faces, and valve stem ends for pits,
burn marks, or other signs of abnormal wear.
NOTE: Whenever a valve is out of tolerance, it
must be replaced.
Cleaning/Inspecting Valve Cover
NOTE: If the valve cover cannot be trued, the cyl-
CC032D
inder head assembly must be replaced.
1. Wash the valve cover in parts-cleaning solvent.
2. Place the valve cover on the Surface Plate covered with
#400 grit wet-or-dry sandpaper. Using light pressure,
move the valve cover in a figure eight motion. Inspect
the sealing surface for any indication of high spots. A
high spot can be noted by a bright metallic finish. Cor-
rect any high spots before assembly by continuing to
move the valve cover in a figure eight motion until a
uniform bright metallic finish is attained.
Do not remove an excessive amount of the sealing sur-
face or damage to the camshaft will result. Always
check camshaft clearance when resurfacing the valve
cover.
CC033D
Water or parts-cleaning solvent must be used in con-
junction with the wet-or-dry sandpaper or damage to
the sealing surface may result.
Removing Valves
NOTE: Keep all valves and valve components as
a set. Note the original location of each valve set
for use during installation. Return each valve set
to its original location during installation.
