the lifter guides should sit perfectly flat on the milled top surface of the lifter bore pairs. If they do not,
stop and figure out why before proceeding. Failure to do so may result in significant engine damage.
3. Installing the lifter retention hardware - Place the
stamped steel lifter retainer in the valley of the block and
see which of the two holes in the retainer line up with
the tapped holes in the cast bosses in the valley. The
fingers of the retainer should be between the pairs of
lifters and riding on the raised ball area of the lifter
guides. It may be necessary to rotate the retainer end for
the end to get the holes to line up. If your bosses are not
drilled and tapped, use the lifter retainer as a guide for
marking the proper location of the future holes. Be sure
that the retainer fingers are centered between the lifter
pairs and riding on the raised ball area of the lifter guides before marking the hole locations. Mark the
holes with a center punch, remove the retainer, and drill and tap the holes as necessary. Do not allow
any metal shavings created during the drilling and tapping process to remain in the engine. Severe
engine damage may result.
4. Final assembly of lifter retainer - Lower the retainer into the
valley, centering the correct holes over the bosses and making
sure once again that the fingers of the retainer are between pairs
of lifters and riding on the raised ball area of the lifter guides.
Start both of the retainer bolts supplied in the kit by hand and
torque to 20 ft lbs.
5. Final check - Spin the engine over by hand at the crankshaft
with a wrench (or COMP Cams® Part #4798 crank socket) and
watch closely the movement of the lifters. As the lifters move up
and down, the lifter guides should remain perfectly flat on the
tops of the lifter bores. They should not be pushed up at all by the
up and down motion of the lifters. If they do, the camshaft does
not have the correct base circle size to be used with these lifters.
Stop here and replace the cam with the proper one before
proceeding, running the engine with this condition in existence
will result in major engine damage.
The installation of your COMP Cams® Ford 302 HO Hydraulic Roller Lifter Kit is now complete.
Refer to the camshaft installation and degreeing instructions that came with your cam for further
instructions on pushrod installation and valve adjustment that are needed to complete your project.
Order COMP Cams® Camshaft Degree Kit (Part #4796) to make these adjustments easier.
