Servicing Top-Side

Components

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 pres-

sure, 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 assembly by con-

tinuing to move the valve cover in a figure eight

motion until a uniform bright metallic finish is

attained.

CC130D

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.

1. Using a valve spring compressor, compress the valve

springs and remove the valve cotters. Account for an

upper spring retainer.

CC132D

2. Remove the valve seal and the lower remaining spring

seat. Discard the valve seal.

CC136D



NOTE: The valve seals must be replaced.

3. Remove the valve springs; then invert the cylinder

head and remove the valves.

Measuring Valve Stem Runout

1. Support each valve stem end with the V Blocks; then

check the valve stem runout using a dial indicator.

ATV-1082

2. Maximum runout must not exceed specifications.

Measuring Valve Stem
Outside Diameter

1. Using a micrometer, measure the valve stem outside

diameter.

2. Acceptable diameter range (intake valve) must be

within specifications.

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.

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.
