Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding.

How the hell does regrinding a cam work?

Jul 29, 2015A cam is a bump on a circle. When the lifter is riding on the circle, it's at zero lift. as the cam rotates, the lifter sides over the bump. Regrinding a cam is making the circle smaller, in order to make the bump bigger so it can be reshaped. Register now to get rid of these ads!

Jordon, now that really makes sense. So you could actually increase the lift and maybe alter the lobe timing a bit by grinding the small diameter side of the cam. But then you must compensate for this change in cam height in other parts of the valve train. Thanks Chuck-----'86 Cab, '77 Targa, Family Truckster

Understanding Camshafts

Camshaft duration is the amount of crankshaft rotation that occurs as the cam lobe moves the lifter off of the base circle; it is measured in crankshaft degrees to make it easier to degree (check) the cam to make sure it is positioned properly in the engine. Determining the specific point that the lobe begins to move, the lifter off of the base circle (upwards) can be difficult--so most camshaft companies use a

Sometimes the journal will be knocked out of center and needs to be surfaced to round and straightened. Consequently, the journal diameter could be positioned out of square at both end of the pins.
