Hand Polishing of Crankshaft Journals | Crankshaft Grinding Equipment | Main Journal Grinding

The crankshaft is the heart of the engine and is the most important/expensive component. It is necessary that the crankpin journal and main journal of the crankshaft are periodically inspected and polished. This not only enhances the life of the bearing but saves the crankshaft from any damage in case it is properly polished.

The oil film between the crankpin/main journal and bearings is too thin while the engine is in operation. In case the main journal and crankpin have roughness, burr, pitting, and line marks it can result in the discontinuation of oil film and failure of bearing causing damage to the crankshaft.

RA Power Solutions during the working on crankshafts of marine Engines for the last four decades have observed that non-conventional methods for polishing of main journal and crank pin journal are adopted to put the engine back in operation.

The non-conventional methods used are as follows:

I) Polishing of crankpin journal and main journal by Jute rope.
II) Polishing of crankpin journal and main journal by various grinding and polishing mediums.

**Consequences of Hand Polishing on Crankpin**

We observed that following these unconventional and nontechnical processes for polishing the crankshaft does not remove the line marks or the various other abnormalities which do get developed. In some cases, since this process has no control excessive taper and ovality are created resulting in the failure of the bearing and crankshaft.

Crankpin and Main Journal Polishing Made Easy:

RA Power Solutions by introducing a lightweight, compact onsite crankshaft polishing machine has made the crankshaft repair process simple with minimum downtime of the engine. The polishing and grinding machine are inserted from the engine block and a polishing crankpin is undertaken. The onsite crankshaft grinding and polishing machine is capable of maintaining a surface finish better than the international standards i.e. 0.2 RA value.
