Crankshaft Repair of Daihatsu 5DC-17 | Save Crankshaft from Rejection

RA Power Solutions have been contacted by various ship owners and Daihatsu 5DC-17 installations all over the world regarding the problems faced by them in the crankshaft of Daihatsu 5DC-17

The details of engine and crankshaft are given below:

Main observations of Daihatsu 5DC-17 crankshaft:-

RA Power Solutions have been working on crankshafts of different makes and models of engine for the last 40 years. In the case of Daihatsu 5DC-17, the crankshaft has a diameter of 145 mm and bearing width of only 64 mm.

Again, the hardness of the crankshaft is between 18 and 24 HRC. A statement showing the hardness of the crankpin in HS, HRC and HB scale is listed below:

Hardness observed of crankpin and main  journal of crankshaft of Daihatsu 5DC-17 engine ( HS TO HRC TO HB) 

Development of ovality In crankpin and main journal of crankshaft of Daihatsu 5DC-17.

It is observed that ovality is developed in the crankpins and main journal of the crankshaft after the continuous running of 3-5 years of the engine.

Since, no crankshaft repair company in the world has the facility and necessary tooling to undertake onsite grinding and polishing of the crankpins having a small diameter of 145 mm and bearing width of 64 mm. They give the following two options to the ship owners.

• To replace the crankshaft with the new crankshaft.
• Remove the crankshaft from the engine, pack it and send it to the designated workshop for grinding and polishing.

We have come across a number of cases where the leading crankshaft repair company based in Europe have rejected the crankshaft as they do not possess the facility of onsite grinding, polishing and repair of crankshaft of Daihatsu 5DC-17.
