1 Engineering Durability Power LIFTERS For years COMP Cams lifters have set the standard for solid roller lifter technology, but today s engine s place an even greater demand on lifters. With today s aggressive cam designs and increased rpm ranges, look to the new COMP Cams Elite Race Solid Roller Lifters.

2 LIFTER TECH Flat Tappet vs. Roller Tappet Lifters In nearly all circumstances, a good roller camshaft design will outperform its flat tappet counterpart. Among the benefits of roller cams are higher tappet velocity, more lift and more area, along with reduced valve train friction (often a 15+ hp increase) and higher engine rpm with little effect on low speed drivability and power. Roller tappets are also reusable, which makes it possible to swap just the camshaft without the expense of new lifters. And finally, roller tappets are far less prone to wear, allowing higher spring loads, and they are more consistent with today s oils. The biggest advantage with a flat tappet cam and lifters is the up front cost. It can be significantly less expensive to use a flat tappet setup but should you decide to install a new camshaft, flat tappets are not reusable. You will need new lifters as well. Hydraulic vs. Mechanical (Solid) Lifters Both hydraulic and mechanical lifter types look the same from the outside, with both having pushrod seats held in by a retaining clip. In a hydraulic lifter the seat moves by means of a hydraulic valve and oil pressure within the lifter. The mechanical lifter does not have a valve and is solid. The pushrod seat in a solid lifter sits upon an internal step inside the lifter body, preventing it from moving. The hydraulic lifter, on the other hand, has a pushrod seat that sits on top of a moveable hydraulic mechanism which acts like a tiny hydraulic pump. Below this mechanism are a valve and spring that produce an upward force, moving the seat up against the pushrod when the lifter is on the base circle. Solid cam designs require a running clearance or valve lash. Hydraulic cams are the exact opposite. In a standard hydraulic lifter the pushrod takes up all of the clearance and submerges into the lifter s pushrod seat approximately.020"-.070". The distance that the pushrod submerges is known as the pre-load. PROS 1. Minimum amount of maintenance is required once the proper pre-load is set 2. Fully adjustable for any changes in block & cylinder head size HYDRAULIC LIFTERS Setting Valve Lash With A Solid Lifter Camshaft CONS 1. Less stiff at higher engine speeds due to hydraulic valve pumping up with high pushrod forces - forcing oil to squeeze out, reducing the running duration 3. Less valve train noise 2. Effective rpm range is limited PROS 1. More accurate & consistent valve timing throughout the entire rpm range 2. Not adversely affected by higher spring loads or increased engine speeds SOLID LIFTERS CONS 1. Takes longer to properly set up & requires regular maintenance 2. Noisier valve train First, check the spec card that came with your cam for the correct valve lash specifications. All COMP Cams valve lash settings are hot settings (set at normal engine operating temperature) but will work for initial start-up as well. Turn the crankshaft in the direction of normal engine rotation until the exhaust pushrod of the cylinder you are adjusting begins to move upward, opening the valve. Adjust the INTAKE lash by tightening the intake rocker nut with the correct thickness feeler gauge inserted between the valve stem and the rocker tip. Tighten the rocker nut until there is a slight drag when moving the feeler gauge. Next, rotate the engine until the intake pushrod fully opens the valve and then goes halfway back down. Adjust the EXHAUST rocker nut (with correct feeler gauge) using the same procedure. Repeat for all cylinders. After setting your valve lash with the engine cold, start it and follow the appropriate break-in procedures. Due to thermal expansion, your valve lash will now be tighter than it was when the engine was cold. Repeat the adjustment process to ensure that your valve lash matches that specified by your cam card at normal operating temperature. Note: Check with COMP Cams on valve lash settings if using aluminum heads or block. Setting Hydraulic Lifter Pre-load (Adjustable Valve Train) When installing a hydraulic cam, lifters or rocker arms, establishing the correct lifter pre-load improves both performance and engine life. Insufficient pre-load will create excessive valve train noise and wear. Excessive pre-load will cause rough idling and low manifold vacuum, and can even lead to severe engine damage. With an adjustable valve train, proceed as follows: 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 number. Turn the engine in its rotation direction until the intake pushrod comes all the way up and almost all the way back down. Now set the EXHAUST rocker to zero lash and add the specified pre-load. Repeat this process for all remaining cylinders. Setting Hydraulic Lifter Pre-load (Non-Adjustable Valve Train) COMP Cams recommends using an adjustable 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. Short Travel Hydraulic Roller Lifters COMP Cams Short Travel Hydraulic Roller Lifters are the perfect choice for use in mandated hydraulic roller racing classes and high performance/race applications. The limited plunger travel extends the usable rpm range by up to 500+ rpm but still remains a hydraulic lifter while staying as close to a mechanical lifter as possible.

Oldsmobile Cyl ,V cc.875"/102g 1.79" The newest addition to the COMP Cams lifter family is the line of Tool Steel Lifters, engineered from M2-grade Tool Steel for its hardness and ability to resist abrasion. Lighter weight but with the same strength as regular steel, these lifters are available in three different diameters, with each diameter available in a coated, non-coated and non-coated EDM version. The DLC (Diamond Like Carbon), multi-layer coating provides the lifters with extremely slick and hard surface properties, making them resistant to abrasive wear in extreme contact pressure environments and compatible with almost any camshaft material. This wear resistance coating also lowers the amount of power required to run an engine s valve train, as well as lowering friction, heat and oil temperatures. Extremely tough and strong, yet lighter in weight than regular steel DLC coating gives lifters slick and hard surface properties Wear resistance requires less power to run valve train and lowers friction, heat and oil temps Three diameters available in DLC coated, non-coated and non-coated EDM versions Part #89842C Part #89842 Part #89842H EDM Oiling Hole Make Part # Description Chevrolet Chrysler Ford 89842H C H C H C-16 Non-Coated for Use on Cast Cams w/ or w/o Nitriding,.012" Oil Hole Non-Coated for Use on Cast Cams w/ or w/o Nitriding Coated for Use on Cams Using Steel Cores Non-Coated for Use on Cams w/ or w/o Nitriding,.012" Oil Hole Non-Coated for Use on Cast Cams w/ or w/o Nitriding Coated for Use on Cams Using Steel Cores Non-Coated for Use on Cams w/ or w/o Nitriding,.012" Oil Hole Non-Coated for Use on Cast Cams w/ or w/o Nitriding Coated for Use on Cams Using Steel Cores Seat Ht..842"/76g 1.88".842"/76g 1.88".842"/76g 1.88".904"/84g 1.88".904"/84g 1.88".904"/84g 1.88".875"/76g 1.88".875"/76g 1.88".875"/76g 1.88" 278

9 Endure-X Solid Roller Lifters Today s engines place a greater demand on lifters than ever before. With today s more aggressive cam lobe designs and increased rpm ranges, it takes a superior roller lifter to withstand the abuse. COMP Cams has set the industry standard with the Endure-X Solid Roller Lifters. Endure-X Lifters are fully heat-treated, machined to ultra-high tolerances, are fully rebuildable and are available for a wide variety of applications, including small base circle and offset applications. A complete application listing is on the following pages 283 through 285 of this catalog. The four main features of Endure-X Solid Roller Lifters are: 1. Removable Link Bar COMP Cams patented link bar assembly combines the benefits of a removable link bar with the safety of a captured link bar. 2. EDM Oil Injection Technology Guarantees that the bearing assembly receives a constant flow of pressurized oil via a precision hole aimed directly at the needle bearings. 3. Precision Sorted Bearings The needle bearings are precision sorted by size to distribute load evenly, preventing premature wear and failure. 2 EDM Oil Injection Technology 1 Removable Link Bar 4. Tool Steel Axle The axle is made of wear resistant Tool Steel to prolong the life of the roller assembly, particularly in high rpm applications. 4 Tool Steel Axle Endure-X Solid Roller Lifter Rebuild Program Today s roller lifters face grueling engine environments. Inadequate oiling, excessive spring pressures and valve lash, along with other factors, play a significant part in the failure of the roller, needle bearings and axle. COMP Cams recognizes the high cost of new parts and designed the Endure-X Lifter Rebuild Program to help offset some of that cost. 3 Precision Sorted Bearing The roller assembly is often the culprit in roller lifter failure. The lifter body can be buffed and the link bars replaced as necessary. However, the roller bearings and axle usually need to be replaced after each season of use or after any catastrophic engine failure. A sudden lack of motion is even more destructive than the sudden application of motion. There is a small fee to replace worn or damaged parts, and replacement lifters may be purchased to replace defective or destroyed ones. This is often less than half of the cost of new lifters and ensures long, trouble free operation. Rebuilt solid roller lifters go through the following steps: 1. Lifter bodies are disassembled and inspected for cracks. 2. Retaining grooves are inspected and cleaned. 3. Lifter bodies are thoroughly washed. 4. A new axle and roller assembly are pressed into the body, and new retaining clips are installed. 5. Lifters are reboxed and returned to the customer.

14 New Elite Race Solid Roller Lifters If you re looking for the ultimate lifter to withstand even the most demanding racing conditions, look no further. The COMP Cams Elite Race Solid Roller Lifters feature a host of advantages over competing race lifter designs, including an REM polished 8620 alloy body that is CNC-machined, SAE 9310 steel alloy wheels that are micro-polished and micro-sized and needles that are made from bearing steel and micro-sorted with a controlled contour profile. These lifters feature an exclusive body design that does not include an oil band, maximizing rigidity and reducing lifter bushing wear. While the construction and body design make them incredibly strong, the Elite Race Solid Roller Lifters are also lightweight, with each lifter weighing approximately 100 grams individually. All lifter bodies are tall and will clear both stock and aftermarket.300" tall lifter bores and will properly fit either 5/16" or 3/8" ball pushrods. Possibly the most critical element of this lifter design is the fact that the oversized (.400") axles are dual-pinned pins go through the lifter ears at each end and leave a small gap in between for oiling. And with this pressure fed oiling you get wear-reducing engine lubrication when and where you need it the most. The oil actually flows through the center and the top of the axle directly to the needles. For maximum control and durability in high rpm race applications, these lifters also feature captured link bars and an exclusive modular pushrod design that allows the pushrod insert to be swapped out for centered, left or right offsets. And with our patent-pending oil control through the pushrod insert, engine builders can modify the lifter to meter extra oil to the top as desired. Elite Race Solid Roller Lifters are fully heat-treated, machined to high tolerances, are fully rebuildable and are available for a number of Chevy, Ford and Chrysler applications. A complete application listing is on the following pages but look for new applications at Elite Race Solid Roller Lifter Oiling Path Pressurized Oil 1. Modular Design Pushrod insert can be changed for centered, left or right offsets. A patent-pending design allowing oil control through the pushrod insert lets builders modify lifters to meter extra oil to the top. 2. Tool Steel, Dual-Pinned Axles.400" Axles (extra large for maximum load support) allow for extra needle bearings (total of 23) for optimum load distribution. Needles are constructed from bearing steel and are micro-sorted with a controlled contoured profile. Dual-pinned axles are pinned through the lifter ears on both sides to allow oiling between them, whereas competitors lifters only use a single pin. 3. Pressure-Fed Oiling Center and top axle oil inlets for lubrication through the axle, directly to the needles exactly where you need it. 4. Captured Link Bars Designed specifically for race and high rpm applications, captured link bars offer maximum control and durability
