May 15, 1995· 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 preturned. The diameter tolerances for crankshafts are often even tighter than those for camshafts.

reamed, but the most practical means is to adjust camshaft journal diameters by grinding. Even if not ground to provide additional clearance, camshaft bearing journals should be polished to a surface finish of 10 microinches Ra or better with the camshaft rotating in .
The crankshaft main journals rotate in a set of supporting bearings ("main bearings"), causing the offset rod journals to rotate in a circular path around the main journal centers, the diameter of which is twice the offset of the rod journals. The diameter of that path is the engine "stroke": the distance the piston moves up and down in its ...
Final size would usually be confirmed by some form of inprocess gauging, directly measuring the actual diameter of the journal by means of a calliper equipped with a suitable measuring device. A popular machine of this type was the "DJ" singlewheel journal grinder, which could be used for both crankshaft and camshaft journal grinding.

Automatic measurement cycle: the measurement head is inserted automatically onto the part diameter while it is being machined, without interrupting the grinding process; Maximum measurement flexibility: Due to the flexibility of the measurement heads, it is possible to process a wide variety of main journal and pin bearing diameters (up to 25 mm)
To calculate camshaft journal oil clearance, subtract the outer diameter of the camshaft journal (outside micrometer reading) from the inner diameter of the camshaft bearings (inside micrometer reading). The standard clearance is in. ( mm)
