In-Place Machining

Performs In Situ Repair

In-Place Machining Company (IPM) performs complete in-situ re- pair and refurbishment of crank- shafts, including crankpin and main journals. Recently the crankshaft of a diesel generating engine aboard a bulk carrier sustained damage when the clamp that retains the crankshaft gear to the crankshaft loosened. It was found that the cy- lindrical mounting surface for the crankshaft gear and two adjacent tapered collars on the crankshaft were badly damaged.

Access for the repair was limited so the crankshaft was removed to the

IPM shop. The gear mounting area had overheated when the crankshaft gear key sheared and the gear spun.

The crankshaft was mounted in a grinder and inspected for hardness, cracking and bending. There was sur- face cracking and hardness. IPM ef- fected the following repair with com- plete approval of the Lloyd's surveyor: the damaged cylindrical surface and tapered surfaces on the crankshaft were machined to remove hard- ness and surface cracking; these areas of the shaft were "brush" nickel plated to increase diameter; the plated areas were ground to original manufactured dimensions; since all the main and crankpin journal surfaces had minor wear marks, the journals were ground .5 mm under size.
