1 Mechanical Roller Lifters Crane roller lifters are the standard by which all others are judged. From our first horizontal locking bar version, with patented roller shield body, to our latest Ultra Pro- Series design, Crane has brought innovation and proven reliability to this critical component. For maximum reliability, pressure-fed oil is routed to the roller wheel and bearings on engines with this oiling system design. This is another Crane pioneered feature. Another Crane innovation is our use of Bearing Focused Oiling. As many racing engines do not have pressurized oil to the lifter bores, a method is needed to supply oil to the bearing assemblies. This utilizes two passages in the lifter body adjacent to the roller wheel, conducting the oil that is pressed out from between the roller and the camshaft lobe to the roller bearings. There are no small passages that can clog, and no engine oil pressure is sacrificed to provide this lubrication and cooling to the needle bearings. Bearing, roller, and axle life is therefore extended by the benefits of a continuous oil flow over these components. Due to the proliferation of factory and aftermarket cylinder blocks (which may have Horizontal Guide Bar Design relocated camshaft locations, relocated oil galleries, changed lifter boss heights, lifter bores of varied diameters and center-to-center distances, etc.), the manufacture and selection of the proper roller lifter has also become more exacting. This listing includes most popular applications available at the time of publication, but new items are being continuously released. We also offer custom roller lifters to suit specialized block-camshaft-cylinder head combinations. Contact Crane s Performance Consultants if you have any unique requirements. Our design roller lifters are suitable for virtually all performance applications. Both the horizontal and vertical locking bar versions are used throughout motorsports today. Our Ultra Pro-Series lifters feature maximized lifter bore contact surfaces for less wear, weight removed from non-critical areas, increased body stiffness, and premium materials chosen wherever necessary. Upgrades to the Ultra Pro-Series lifters include carburized 8620 steel bodies, upgraded materials and metal processing for the roller wheels, needle bearings, and axles. A new guidebar attachment system incorporates a retaining button in conjunction with an aerospace quality monel pin to provide superior clamping forces and resistance to wear. Extreme Spintron and track testing has confirmed this configuration to be superior to anything else on the market today. All machining, and assembly is performed at our own facilities, insuring absolute accuracy and total quality control. The spring-loaded horizontal locking bar lifters have the unique feature of permitting cam changes without intake manifold removal (providing a rev-kit is not used). Loosening the rocker arms and removing the pushrods allows the springs to pick the lifters up away from the camshaft. The cam can then be removed and replaced in minimal time. This convenience is especially helpful during dyno and on-track testing sessions. We do not advise the use of oil restrictors with our roller lifters. Crane roller lifters are designed for use with normal oiling systems. The needle bearings within are dependent on oil flow to provide lubrication and transfer of the heat generated by today s high valve spring pressures and increased rocker arm ratios. Particularly hard on these components are prolonged periods of idling when oil flow is at a minimum but spring pressures are still high. Whenever possible, standard pushrod seat height is maintained from the bottom of the wheel so that normal length pushrods are used. In consideration of special geometry applications, the seat may be higher, or lower, than standard for best fitment. These instances are noted in the application description where required. The pushrod socket radius is usually stock, and any deviations are also noted in the application description. How to Identify Roller Lifter Offsets: When ordering spare lifters with offset pushrod seat locations you MUST specify left or right offset. For example, a pair of lifters for set number would be either 11571L-2 (left) or 11571R-2 (right). See drawing to identify lifter offsets. C L C L Guide Bar Right Offset Left Offset Block machining is not normally required for the installation of these lifters (other than the lifter bore diameter options), however with differences in block castings and camshaft base circle diameters, care must be taken to ensure that the lifter, locking bar, and locking bar attaching rivets (where applicable), do not encounter any bind, or unwanted contact, throughout their normal cycles. If there is any interference, the block can usually be ground to provide the necessary clearance. This should be checked prior to final engine assembly. 296
2 Mechanical Roller Lifters (continued) We do not advise the use of offset pushrod seat roller lifters, when the pushrod angle imparts rotational forces upon the lifter. Offset roller lifters are acceptable for use when the pushrods are angled to the front or rear of the engine (parallel to the camshaft). If the pushrods lean toward the left or right of the lifter bores (as viewed from the front or rear of the engine), this will put severe loads on the lifter guidebar and it s attaching mechanism, which can lead to decreased reliability and possible failure. When building a serious racing engine, it s advisable to avoid using offset lifters whenever possible. Offset lifters can also be responsible for accelerated wear to the lifter bores, lifter bodies, roller wheel/bearings/axles, and cam lobes. Plan ahead when choosing and preparing your cylinder block and heads, so you can use centered lifters for best reliability. Vertical Guide Bar Design Choose The Right Crane Roller Lifters for Your Design or Ultra-Pro Roller Lifters? With the release of Crane Cams new Ultra-Pro series of roller lifters, you might be wondering just which series of lifters is right for your application. Listed below are some guidelines for making the correct choice and getting the best performance for your dollar. Design Crane roller lifters were developed when camshaft lobes were not nearly as violent as today. They are ideal for street-rollers, many bracket-race type applications and other racing uses where cam profiles aren t as aggressive. Made of carburized (heat treated) 8620 alloy steel, these rollers are capable of handling up to 240 lbs., of valve spring seat pressure in bracket race applications and up to 220 lbs., of seat pressure in endurance applications providing the cam lobe profile is not extremely violent. Open pressures exceeding 600 lbs., are not recommended for these lifters. Design lifters feature high quality wheels and axles that look alike lifters do not have. You ll find that the materials, machining tolerances and overall quality of Design roller lifters far exceeds lifters being sold for a lower price. These roller lifters feature all the quality and durability you expect from a Crane Cams product yet they are very economically priced. Crane Ultra-Pro roller lifters are the ultimate in state-of-the-art, drop-in design premium quality roller lifters! Empirical design and development techniques have been used to eliminate any distortion effects of residual stresses resulting from the heat treat process. Ultra-Pro roller lifters feature maximized strength; especially in the axle support struts. This insures geometrically perfect tracking of the roller wheel. Additionally, super-premium wheels, axles and bearings made from the finest grades of alloy steels are used to conquer even the most violent cam lobe profiles currently designed or anticipated for the next several years! These lifters represent the best combination of lightweight, ultimate strength and reliability. They should be used in all drag race applications with spring seat pressures in excess of 300 lbs., and open pressures over 800 lbs. In addition, they should be used in any short-track circle or endurance racing application where valve spring seat pressures exceed 250 lbs., and open pressures exceed 700 lbs. Use Crane Cams Ultra-Pro series lifters when absolute durability is necessary. With Crane Cams Ultra-Pro roller lifters, engine builders can now be sure that they re using the absolute finest available, professional quality roller lifters for high-stress race engine applications.
