What causes a camshaft to fail on a roller wheel?
This high spring pressure causes the heat created at the cam to be transferred to the roller wheel, resulting in its early failure. Any springs that may be used must be assembled to the manufacturer’s recommended height. Never install springs without verifying the correct assembled height and pressures.
When to replace camshaft bearings in an engine?
Replacing camshaft bearings during an engine rebuild is a no-brainer, but don’t take the process lightly. Simply knocking out the old bearings and installing fresh ones with little regard to bearing selection, sizing or alignment is a big mistake.
What’s the minimum clearance for a cam bearing?
Minimum clearance should be 0.002˝ for stock engines and 0.003-0.004˝ for high-performance engines. If cam fit is too tight, bearing material can be removed by reaming.
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.
Do you put lubricant on cam bearings before they are pressed in?
McBroom also advises that on some blocks such as cast iron blocks, it helps to put a film of lubricant on the bearing before cam bearings are pressed in. “Sometimes the bearing can gall and produce an asperity on the inside of the bearing because it is put together dry,” he says. “Surface finish on the cam journals can also be an issue.
