apply. Select the proper size expand-
ing collet and back-up nut and as-
semble on the expanding mandrel.
With the expanding collet collapsed,
install the collet assembly in the cam-
shaft bearing, and tighten the back-
up nut on the expanding mandrel
until the collet fits the camshaft bear-
ing. Assemble the puller screw and
extension (if necessary) as shown and
install on the expanding mandrel.
Tighten the pulling nut against the
thrust bearing and pulling plate to
remove the camshaft bearing. Be
sure to hold a wrench on the end of
the puller screw to prevent it from
turning. Repeat the procedure for
each bearing. To remove the front
