Installation
Step 1
After removing the rockers and other components from the package thoroughly wash each piece, and then
blow dry.
Step 2
Prior to installation, submerge the rockers in engine oil for approximately 30 minutes to insure the roller
tip and fulcrum are properly lubricated.
Step 3
Install the push rods. Make sure the pushrod is properly seated in the lifter. Fill each pushrod with engine
oil, one at a time, as you install each rocker arm. This is to assure immediate lubrication when the engine
is started and helps prevent any galling.
Step 4
During installation, apply Extreme Pressure Lube #3 sparingly; to each push rod tip, rocker arm push rod
seat, the top of the valve stem where it comes in contact with the roller tip, and at the curved side of each
pivot ball. Install the rocker arm on the rocker studs. Check to make certain that each pushrod is seated
properly in the rocker seat and in the valve lifter. Install pivot ball flat side up. Thread the RockerLocs
onto the rocker arm stud but do not tighten.
Step 5
Solid Lifter Cams: Following OEM rocker arm installation guidelines and/or detailed instructions
provided by your camshaft manufacturer, adjust the valve lash with a feeler gage to the specifications
provided.
Hydraulic Lifter Cams: Following OEM rocker arm installation guidelines and/or detailed instructions
provided by your camshaft manufacturer, adjust the valve lash at the Top Dead Center of each cylinder or
at the “base circle” of the intake/exhaust valve cycle. T ighten each adjuster nut until all of the “slack”
between the rocker arm and pushrod is gone. Turn the pushrod with your fingers as you tighten the
adjuster nut. Do that until you feel a slight resistance when turning the pushrod; indicating that you have
reached “ zero” lash. At this point turn the adjuster nut another ½ turn.
Step 6
Adjusting Intake Valves: Follow this procedure for all of the intake valves. Generally the procedure is
to hand turn crankshaft in the running rotation, checking each cylinder to identify when the exhaust
pushrod begins to move upwards. This will indicate that the intake valve lifter is at the “base circle” of
