INSTALLATION
Apply an appropriate Teflon
®
thread sealant to
the threads and install the plug. Tighten the plug
to specification. Refer to the torque chart in the
SPECIFICATIONS section.
New plugs may already have a sealer applied to
the threads. Applying a Teflon
®
sealer to the
threads will not adversely affect the precoating.
H-Ring Replacement
[213 LD]
H-rings are placed in the lifter bores to prevent
the lifters from turning, and performing the same
function as the roller tappet guide pins used with
electronic unit pumps. The H-rings have an
interference fit with the lifter bores in which they
are installed and, under normal circumstances,
are never removed.
If an unusual failure situation results in an H-ring
being dislodged, it can be reinstalled or replaced
with a new part, as required, using the following
procedure:
1. Remove the affected H-ring, using remover
tool J 42426 in combination with slide
hammer J 6125-1B. Refer to Figure 194.
