INSTALLATION INSTRUCTIONS:
Note: The alignment of cam bearing bores can change as an engine
block ages and in some cases the bores can get out of round.
When new bearings are installed in such a block, the camshaft may
be difficult or impossible to install properly. Small amounts of
warpage may be corrected by scraping the bearing but large
amounts need to be corrected by align boring or honing. Either of
the above conditions may make cam bearings difficult to install
and may result in damaged bearings.
Step 5 - Place nylon cone in first bearing housing and
drive bearing out. Loosen driver assembly to relieve
pressure and pull tool back through the next bearing to
be driven. Repeat above steps
until all bearings are removed. WARNING:
