Account for the opposite-side circlip. 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

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 cylin-
der 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. Correct any high spots before assem-
bly by continuing to move the valve cover in a figure
eight motion until a uniform bright metallic finish is
attained.
CAUTION
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.
CC130D
CAUTION
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: Index all valves, springs, and cotters to their
original position when removing. When installing, all
valve components should be installed in their original
position.
1. Using a valve spring compressor, compress the valve
springs and remove the valve cotters. Account for an
upper spring retainer.
