Lifters - Hydraulic Roller<br />
Hydraulic Roller<br />
<strong>Crane</strong> hydraulic roller lifters are offered in two basic designs: Those for use with standard factory<br />
alignment bars (on engines originally equipped with hydraulic roller lifters); and vertical locking bar<br />
drop-in lifters (designed to retrofit engines not factory equipped with hydraulic roller lifters).<br />
The Chevrolet standard alignment bar lifters are available in a normal dimensioned version, intended for<br />
use with standard lobe lift and standard base circle diameter cams. When lobe lifts increase, and<br />
base circle diameters decrease, our exclusive long travel design lifters must be used to prevent the<br />
lifters from dropping out of the factory alignment bars when on the base circle of the camshaft. This<br />
would allow the lifters to rotate, causing severe engine damage. As these lifters are for engines<br />
originally equipped with hydraulic roller lifters, special length pushrods are not usually required.<br />
Our retrofit vertical locking bar lifters are available for non-hydraulic roller equipped engines.. They<br />
can also be used in many applications to replace factory hydraulic roller lifters and alignment<br />
mechanisms. No machining is normally required for the drop-in installation of these lifters, however<br />
with differences in block castings and camshaft base circle diameters, care must be taken to insure that<br />
neither the locking bar, or its attaching rivets, contact the block casting throughout their normal<br />
cycles. If there is any interference, the block can usually be ground to provide the necessary clearance.<br />
This should be checked prior to final engine assembly. When used in retrofit applications, special length<br />
pushrods are required.<br />
The retrofit vertical locking bar lifters are machined from 8620 steel billet, heat treated, and assembled<br />
at our own facilities. Precision fit plunger assemblies are used to provide proper bleed-down rates,<br />
permitting high RPM use in properly set-up engines. The additional inherent strength of the 8620<br />
material also maintains greater stability in the lifter body, permitting more consistent operation in<br />
very high spring pressure and high RPM applications, by keeping the plunger to body clearance<br />
consistent throughout the operation range. Retrofit lifters also utilize our latest Monel pin and<br />
retaining flange assembly to attach the guidebar, providing superior long term durability.<br />
Each lifter has its pushrod seat height listed. This is the measurement from the bottom of the pushrod<br />
seat, to the bottom face of the lifter. For hydraulic lifters, this is the measurement with no (zero) lifter<br />
preload. You can check or compare your lifters to these dimensions by placing a 5/16” diameter ball in<br />
the pushrod seat, and measuring from the bottom of the lifter to the top of the ball. Then subtract the<br />
5/16” diameter of the ball, obtaining the seat height.<br />
