Hydraulic Tappets

Valve Installation

When installing valves in the cylinder head, coat the

valve stems with oil before inserting them into the valve

guides. Make sure the valves move up and down

smoothly.

When the valves and springs are in place, lightly tap the

end of each valve stem two or three times with a plastic

mallet to ensure proper seating of the valve and valve

keepers.

NOTE:

Make sure that the valve keepers are properly posi-

tioned on the valve stem.

Tap the valve stem only along its axis so you do not

bend the stem.

7.
If the plastigage measures too wide or too narrow,

remove the upper half of the bearing, install a new,

complete bearing with the same color code (select

the color as shown in the right column of this page),

and recheck the clearance.

CAUTION: Do not file, shim, or scrape the bearings

or the caps to adjust clearance.

If the plastigage shows the clearance is still incor-

rect, try the next larger or smaller bearing (the color

listed above or below that one), and check clear-

ance again.

NOTE: If the proper clearance cannot be obtained

by using the appropriate larger or smaller bearings,

replace the crankshaft and start over.
CAUTION: If the codes are indecipherable because of

an accumulation of dirt and dust, do not scrub them

with a wire brush or scraper. Clean them only with sol-

vent or detergent.

Connecting Rod Code Location

Numbers or bars have been stamped on the side of each

connecting rod as a code for the size of the big end. Use

them, and the letters or bars stamped on the crank

(codes for rod journal size), to choose the correct bear-

ings.
