REPAIR INSTRUCTIONS, PART 1
2. Submerge the valve lifters into a container of
clean engine oil to allow oil to fill the
passages to the roller axles. Remove each
lifter and while holding it vertically, spin the
roller to make sure the oil flows to the
surfaces between the axle and roller. This
step is important to provide adequate
break-in to the axle and roller at initial
start-up of the engine.
3. Install the lifters into the cylinder block lifter
bores as shown in Figure 348.
Used valve lifters
have established wear
patterns. Valve lifters being returned to service
should be installed in the same location from
which they were removed.

4. Install a lifter in the lifter bore by aligning the
lifter flats with the H-ring flats (Figure 349).
Use only light finger pressure when installing
the lifters. Verify that the lifter has complete
freedom of movement in the bore and H-ring
in both the upward and downward
directions. When the lifter is seated, it should
be possible to rotate it slightly from left to
right. If the lifter is sticky or tight, or if
additional force is required to install the lifter,
proceed as follows:
a.
If new lifters are being installed and the
fit is tight, try the lifter in another lifter
bore. A stack-up of component
tolerances can result in a lifter being
free in another bore. This is acceptable.
b.
If the original lifters are being reused
and the fit is tight, trial fit a
new
lifter(s)
in the bore. If the tightness persists, the
problem may be in the lifter bore or
H-ring. (Because of established wear
patterns, it is not recommended to
install a used lifter in any bore other
than the bore from which it was
removed.)
c.
If the problem is confined to a particular
bore, determine if the lifter tightness is
due to the lifter bore or the H-ring by
trial fitting another lifter. To correct the
problem condition, refer to the
procedure under “Salvaging a Valve
Lifter Bore” or “H-Ring Replacement” in
the CYLINDER BLOCK
RECONDITIONING section.
A lifter that does not move freely in the lifter bore
can be impacted by the cam lobe during engine
operation. This will result in damage or breakage
of the ceramic roller.
