Directions for crankshaft grinding and MAHLE Aftermarket

Crankshaft journal surfaces should be ground and polished to a surface finish of 15 micro inches roughness average Ra or better. Journals on highly loaded crankshafts such as diesel engines or high performance racing engines require a finish of 10 micro inches Ra or better. Grinding and polishing produces burrs that are so small that we can

Crankshaft Engine Problem, Cracked / Worn / Broken / Bent

Some cranks must be nitrided during the grinding process and run fairly hard bearings. The introduction of embedded abrasive material can wear the crank pins and journals more than expected leaving the bearings at first glance relatively unscathed. When the lack of nitriding is the suspect cause all journals will generally be similarly affected.
