Valve guide replacement
(1) Remove valve guides as follows:
(a) Use a valve guide puller to the head
of a ¾-16 bolt. Place the tool
retainer over the valve guide inside
the rocker box. Insert the ¾-16 bolt
into the retainer and valve guide.
From inside the cylinder, insert the
3/8-24 bolt into the end of the larger
¾ bolt. Tighten the 3/8 bolt until it is
against the valve guide. Turn the
nut in the rocker box clockwise until
the valve guide is out of the cylinder
head.
(2) Install valve guides as follows:
(a) Prior to installation of a new valve
guide, measure the guide hole to
determine if an oversize guide must
be used. Refer to Tables 72-00-
13.9 and 72-00-13.10 and Figure
72-00-13.6. Use a hole plug gage
and measure each valve guide hole.
Determine if a standard size or
oversize guide must be used. Refer
to Tables 72-00-13.9 and 72-00-
13.10.
(b) Fasten the cylinder in place on a
guide replacement tool. Set the tool
