Valve Yoke Guide Pin Replacement
[213 FH]
Valve yoke guide pins are located between each
set of inlet and exhaust valve guides on engines
produced before March 2, 2000. Beginning with
March 2, 2000 production (engine serial
No. 0D0120), valve yoke guide pins are located
only between each set of exhaust valve guides
since these engines use pinless valve yokes to
actuate the inlet valves.
INSPECTION
Inspect the valve yoke guide pin surface for
cracks or other damage. Also check the pin
diameter and installed height.
REMOVAL PROCEDURE
Remove a broken pin as follows:
Due to the hardness of the valve yoke guide pins,
drilling and tapping must be done slowly with
sharp tools and with plenty of lubrication.
1. Center punch the broken section of the pin
in the cylinder head prior to drilling.
The punch mark must be close to the center of
the broken pin to control the drilling operation.
2. Using a drill press, drill a 13/64-inch pilot
hole completely through the broken section
of the yoke pin.
A drill press is strongly recommended to keep the
drilled hole straight with the yoke pin hole in the
cylinder head. Use care when drilling to “feel”
when the drill bit passes through the yoke pin and
contacts the cylinder head. Stop drilling at that
point to avoid drilling through the head and into
the water jacket.
3. Drill a 5/16-inch hole completely through the
broken section of the yoke pin.
