- 0.842 inches diameter; 97 gram weight; 2.05 inches seat height
- Patented orifice metering valve precisely meters oil to the rocker arms
- Continuous contact between metering valve and hardened pushrod seat is maintained, eliminating excessive oiling at high engine speeds
- Contain a longer piston than conventional hydraulic lifters, which provides more load bearing surface and increases lifter longevity
- Lightweight check valve disc allows for quicker response and maintains added control at all engine speeds and loads
High Energy Hydraulic Lifters
Patented Innovation
Patented orifice metering valve precisely meters oil to the rocker arms. Continuous contact between the metering valve and pushrod seat is maintained, eliminating excessive oiling at high engine speeds.
Superior Design for Extended Durability
High Energy hydraulic lifters are made of a superior powdered metal iron alloy which adds strength and wear resistance.
Improved Performance
The lightweight check valve disc allows for quicker response, which allows for extended engine speed before valve float.
Hydraulic Lifter Pre-Load Adjustment
Key Terms
Zero Lash
- Slight resistance when spinning the pushrod between your fingertips after taking up all of the clearance.
Pre-Load
Number of turns applied to adjusting nut after reaching zero lash.
Adjustable Valve Train
Install the pushrods and rocker arms. Be sure the pushrods are seated correctly in the lifter and rocker arm. Turn the engine over in the direction of rotation until the Exhaust pushrod just begins to move upward, opening the valve. Now adjust the Intake rocker of that cylinder. Carefully tighten the nut on the intake rocker while spinning the pushrod with your fingertips. You will feel a slight resistance in the pushrod when you have taken up all of the clearance. This is zero lash.
Turn the adjusting nut to the specified pre-load – typically 1/4-3/4 of a turn, but this will vary based on the lifter model and the thread pitch of the rocker stud. Comp Cams Short Travel Lifters requires 1/4-1/2 of a turn.
Non-Adjustable Valve Train
COMP Cams recommends using an adjustable/checking pushrod to check the pre-load. Typically, only one cylinder needs to be checked in this process. After applying lube, install the adjustable pushrods and assemble the valve train.
Using the same procedure mentioned earlier, adjust the intake and exhaust valves to zero lash by changing the length of the adjustable pushrod for precise fitment. Order a pushrod that is .020"-.070" longer than the pushrod length at zero lash to ensure the proper pre-load.
