NOTE: To achieve proper lifter pump up, it is critical that
both the oil and oil filter in the engine are changed prior to
installing your new lifters. Install the lifters using a high quality
engine oil (5W30 or 10W30). Briefly dip the lifters in fresh, clean oil
just before installation. Do not soak the lifters for a long period of
time before installation.
•
When installing retrofit hydraulic roller lifters, make sure the guide
bar faces the opposite side of the block. (Example: If facing the front
of the engine, lifters being installed on the left side, should have
guidebars facing the right side of the block).
•
Roller camshafts in 1986-earlier Chevrolet engines require a Thrust
Button to control camshaft end play. Check camshaft end play with
the timing cover and timing cover gasket in place. End play should
be kept between .005" and .008". Check end play without the roller
lifters installed. If end play is excessive, a thinner timing cover
gasket may be used to correct end play. Sheet metal covers should
use a waterpump with a cam-stop to prevent timing cover flex.
•
Most Ford engines use a thrust plate to control end play, and do not
require the use of a thrust button. Check end play clearance
according to factory specifications.
1. If using lifter installation kit 97386 or 97387, install the lifters using
the supplied lifter guides to line up the lifters.
2. Install the lifter hold down spider over the lifter guides. Make sure
each tab on the spider contacts the center of each lifter guide.
3. Secure the lifter hold down spider to the lifter valley using the three
supplied hold down bolts. Torque bolts to 18 ft./lbs.
4. Adjust lifter preload as described in the "Installation Notes" section
on Page 1.

Refer to a service manual for your particular application or see
instructions for the camshaft being used for directions on removal
and installation of lifters. These lifters do not replace original flat
tappet lifters, and may only be used with hydraulic roller camshafts.
•
When installing these lifters on Ford 289-302 engines, the cylinder
heads must be removed to gain enough clearance to install the
lifters.
Refer to a factory service manual for your particular
vehicle/engine for cylinder head removal instructions.
•
Hydraulic roller lifters require adjusting the lifter preload. Adjustable
rocker arms or pushrods are required. Adjustable roller rocker arms
are recommended. Hand rotate the engine until the #1 cylinder is at
TDC firing position (Both #1 lifters are down in the lifter bores). You
may now adjust intake and exhaust preload on that cylinder as
follows: You need to set rockers at zero lash. While tightening the
rocker nut, spin the pushrod, when you feel resistance, you are at
zero lash. Tighten rocker nut three quarters to one full turn past zero
lash. Adjust lifter preload one cylinder at a time. Rotate the engine
90° until the next cylinder in the firing order is at TDC and adjust
lifter preload as described above. Continue this process until all
cylinders are adjusted.
