— A motorcycle makes a grinding noise while starting if the starter motor starts okay but rubs against the flywheel and fails to engage completely. ... Finally, a worn crankshaft bearing can wobble the crankshaft arm from side to side when brushed with force from the piston cycle. If it rocks hard enough, it can cause tapping and knocking …
— In path-controlled grinding, unlike the cylindrical plunge grinding, the contour of the pin journal is achieved with the coupling actions both of the eccentric rotation of the pin and the grinding wheel linear movement. Since the circumferential feed rate varies periodically in path controlled grinding of crankshaft pin, the tangential and normal …

— Looking for a little advise on some bad crank grinding I recently had done on a 650 crank. I sent the crank out with instructions to go .01 under on both rod journals and match the corner radius. When I got the crank back the journals were both about .0007 over the maximum spec and I wasn't comfortable with the tight oil clearances I was getting.
The CGA series crankshaft grinders move the grinding head. The workpiece is clamped by the headstock fixed on the base and tailstock moving on table support by air. Grinding wheel carriage is movable on Z and X axes by ballscrew and guideways. Permitting the grinding wheel to move reduces the overall machine dimensions.

Novel mathematical models to predict crankshaft pin grinding forces, out-of-roundness and thermal damage were developed as part of this thesis. The models were validated at a local automotive manufacturer's plant. The outcomes of this research have resulted in reduced scrap and warranty costs, improved manufacturing process quality and reduced lead times.
