Crankshaft failures cause long engine downtime and high expenses.  In-situ crankshaft repair, whenever feasible, is in many cases a cost-effective solution for minimizing downtime and eliminating costs.

Through intensive R&D and field trials, KIMI developed a cutting edge journal tooling for in- situ machining. Until today, KIMI has successfully carried out in-situ machining for a number of different cases, always without dismantling the crankshaft from the engine.

Our value proposition is our people as our in-situ travelling team consists of highly skilled personnel.  Our technicians are not just trained in the use of the in- situ machining equipment, they are material engineers specialized in identifying failure causes, evaluating crankshaft damage and proposing the most appropriate refurbishment solution. In-situ technicians are available round-the-clock worldwide to inspect and offer immediate solution. The tooling is light enough to travel with our team on the same flight and we do our best to send our team on the same day that breakdown occurred, whenever possible.

With our crankshaft repair service we offer:

  • Machining or grinding of crankpin and main journals- diameter range 160-600 mm
  • Grinding of crankpin and main journal fillets
  • Machining and reaming of coupling bolt holes
  • Full reporting of crankshaft condition prior and after refurbishment

In order to ensure excellence in our service our technicians carry out the following supplementary services:

  • NDT Inspection- NDT services and certificates are issued by certified personnel (Level II EN473)
  • Hardness Testing – Hardness certificate in accordance with ISO 17025
  • Heat Treatment

Wherever dismantling and transportation of the crankshaft is not difficult or uneconomical, KIMI offers the laser cladding solution. Laser cladding benefit is the restoration of the journals back to their original diameter which is also a one-way solution in cases that undersized bearings are not available in the market, crankshaft is not available in the market or crankshaft replacement is too expensive.
