WilWES AND WALfE SPRINGS
The valves are arranged in-line and inclined 18°.
The rocker pivot support and the valve guides are
cast integral with the heads.
This procedure requires the removal of the cylinder
head.
REMOVAL
(1) Remove the cylinder head.
(2) Compress valve springs using Valve Spring
Compressor Tool MD-998772A.
(3) Remove valve retaining locks, valve spring re­
tainers, valve stem seals and valve springs.
(4) Before removing valves, remove any burrs from
valve stem lock grooves to prevent • damage to the
valve guides. Identify valves to ensure installation in
original location.
VALVE CLEANING
Clean valves thoroughly. Discard burned, warped
and cracked valves.
Remove carbon and varnish deposits from inside of
valve guides with a reliable guide cleaner.
VALVE
INSPECTION
Measure valve stems for wear. If wear exceeds
0.051 mm (0.002 inch), replace the valve.
VALVE GUIBES .
Measure valve stem guide clearance as follows:
(a) Install Valve Guide Sleeve Tool C-3973 over
valve stem and install valve (Fig. 5). The special
sleeve places the valve at the correct height for
checking with a dial indicator.

(b) Attach Dial Indicator Tool C-3339 to cylinder
head and set it at right angle of valve stem being
measured (Fig. 6).
