Ridge Engine Machine & Repair offers crankshaft grinding and polishing, crankshafts are cleaned magnafluxed for cranks and checked for straightness.

Crankshafts are then put into our Peterson crankshaft machine and ground to the next available undersize bearings. Once the grinding is done, crankshafts are then polished for a smooth finished surface and then cleaned and ready for assembly. We are able to handle crankshafts from one cylinder engines up to Class 8 diesels and agricultural engines.
