What are the rules for replacing cam bearings?
What are the rules for replacing cam bearings?
Finally, you must clock each bearing to align with the oiling holes in the block. Failure to do so will result in a catastrophe. Each bearing should be installed dry, without any lubricant or oil on the block or the outside of the bearing. Replacing the cam bearings is not incredibly difficult as long as you follow the rules and pay attention.
Is the camshaft bearing driver installation tool good?

Which is better aluminum or aluminum cam bearings?
The benefits of aluminum cam bearings, however, far outweigh the compromises. You simply need to pay more attention to details when installing aluminum cam bearings and be certain to verify critical tolerances. Cam bearings are usually available in a range of basic bearing constructions.
What kind of bearings do I need for a camshaft?
When installing cam bearings, always work your way from the rear of the block forward. When fitting aluminum cam bearings, it’s important to allow sufficient bearing-to-camshaft clearance, since the harder aluminum alloy bearings won’t wear in as rapidly as babbitt bearings to make their own clearance.
When to remove and replace cam bearings without damage?

How are cam bearings installed into a block?
Installation of cam bearings into the block must be done carefully to avoid shaving material from the outside diameter of the bearings. This can easily cause a buildup of excess material between the bearing and the block’s bearing bore, which will “squeeze” the bearing, resulting in oil clearance reduction at the bearing inside diameter.
When do you start the cam bearing selection process?
The installation process begins after you’ve accomplished any machining that might be needed (cylinder boring and/or honing, align-honing, deck resurfacing, cam bore alignment, etc.). Before starting, make certain that the block is totally clean.
Do you need to block oil feed holes on cam bearings?
When installing roller type cam bearings, there is usually no need to block or restrict oil feed holes to the cam bearings. Roller type cam bearings usually require only splash lubrication. However, oil feed holes can be blocked off to reduce oil aeration and windage losses, depending on the application.
How big should a roller bearing be for an aluminum block?
If you’re installing the roller bearing in an aluminum block, the bearing cage should have between 0.001″ to 0.0015″ press fit to the cam bore. For proper installation, Comp Cams recommends using a thermal technique as opposed to pressing the bearings into place under ambient temperature.
Can a cam tunnel be used for roller bearing?
There are a few aftermarket blocks that are already machined for a particular size roller bearing. If you do not have this type of block, then the cam tunnel must be bored to accommodate the specific size of roller bearing that you plan to use.
Finally, you must clock each bearing to align with the oiling holes in the block. Failure to do so will result in a catastrophe. Each bearing should be installed dry, without any lubricant or oil on the block or the outside of the bearing. Replacing the cam bearings is not incredibly difficult as long as you follow the rules and pay attention.
Where does the oil hole line up in a camshaft?
Note: If the oil feed passage in the block or head is just a hole without a 360° groove, the bearing oil hole must line up with the oil feed passage in the block or head. In some instances, the bearing oil feed hole in the cam bearing also lines up with a groove cut in the camshaft journal.
Where is the oil groove on a Dura Bond Bearing?
Blocks and heads using a 360° oil groove located behind the bearing oil feed, allow one to move the clock position of the cam bearing oil feed hole. This way you can adjust the clock position during cam bearing installation to make sure that the optimum location for the best hydrodynamic wedge is selected.
Why do cam bores need to be aligned?
Just as a block’s main bores can become out of round or misaligned (creating the need for align-boring or align-honing), the cam bores can be subjected to similar geometry changes. This is why camshaft fitment problems sometimes occur when dealing with a used block.
