During the remanufacturing process the machinist is mostly concerned with grinding the rod and main journals. Upon initial inspection of the crankshaft, with the use of the micrometer, the machinist will determine what bearings need grinding. Indicators that a journal needs grinding include if the surface has wear and make it rough to the touch.

Landis pioneered "chase the pin" or orbital grinding technology to provide a new level of flexibility and precision in finish grinding of automotive and diesel camshafts and crankshafts. The technology is applicable wherever high-speed interpolation and high stiffness are required in the grinding system.

Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding. The main differences are: Camshafts are rough ground directly from the cast condition, while crankshafts may have to be pre-turned. The diameter tolerances for crankshafts are often even tighter than those for camshafts.

Grinding a crankshaft is a process of removing material from the journals in an effort to refurbish and reuse an expensive, yet vital component of an engine. It is usually done during the process of rebuilding an engine when needed, but also has some performance aspects which come along with the process.

The camshaft can then be lowered into the block straight down, so there's minimal effort needed to assure that the cam lobes and cam journals DO NOT nick the bearings. If the cam MUST be installed horizontally, it is mandatory to use a "handle" of some sort on the front of the cam, and to take particular care that the cam doesn't bang into, or scrape across the bearings. Whether vertical or ...
