Daihatsu 5DK-20 Crankshaft repair | RA Power Solutions forty-three years of experience

Daihatsu 5DK-20 crankshaft has been successfully repaired by RA Power Solutions technicians on board a vessel recently. A leading shipping company based in Greece operating more than fifty container vessels approached RA Power Solutions to repair the crankshaft of Daihatsu 5DK-20 on the vessel.

The main challenge was that the crankpin no. 03 of Daihatsu 5DK-20 met with a serious accident damaging the radius fillet of both sides of the crankpin. They had a stopover of only 18 hrs at Mundra Port India.

In fact, the owners disparately tried to get the crankpin repaired in Dubai and approached leading companies but none of them was able to repair the crankpin with a damaged radius filet.

Major Technical Details Of Daihatsu 5DK-20 Crankshaft

S. NO	Crankshaft Details
1.	Engine Make	Daihatsu
2.	Engine Model	5DK-20
3.	Crankpin Diameter Standard	170 mm
4.	Crankpin Bearing Width	78 mm
5.	Place of execution of crankshaft repair	Mundra Port India

Action taken by RA Power Solutions for successful repair of Daihatsu 5DK-20 Crankpin

Dimensional inspection of the crankpin no. 03 was done by the technicians and an ovality of 0.49 mm with deep bearing marks, rough surface, etc was observed.
The radius fillet of both sides of crankpin no. 03 was damaged badly in fact the original profile of the fillet radius of Daihatsu crankshaft was lost due to an accident.
Hardness and crack detection tests were undertaken and were found within limits.
Deflection was also within the parameters.
Our technicians with the help of specially designed compact dedicated tooling for repair of crankpin having small bearing width used the equipment. They reduced the diameter of the crank pin by 1.0 mm and maintained the final diameter of 169.00 mm. Maintaining the tolerance within 0.02 mm, the preparation & formation of radius fillet on both sides of the crank pin was a challenge which was done by our technicians within 18 hours of boarding the vessel.
In this case of Daihatsu 5DK-20 the crank pin bearing width is only 78 mm and with our specially designed equipment it was possible to undertake the grinding.No other company have the compact tooling to undertake such repairs on site without removing it from the engine block.
The bearing is only 1.0 mm undersize and was supplied by RA Power Solutions. The engine was commissioned during the presence of our technicians on board the vessel.

Compressor Crankshaft Grinding and Polishing Onsite

RA Power Solutions was approached by a leading Fertilizer producing company based in north India regarding the requirement of onsite grinding and polishing of compressor crankshaft.

The company has five high-capacity CO2 compressors which have been imported from a leading company based in Europe.

Our team consisting of three technicians along with onsite crankshaft grinding equipment was deputed to the site and following was observed:

Details of CO2 Compressor Crankshaft:

S. NO	Crankshaft Details
1	Engine Make/ Model	CO2 COMPRESSOR
2	Crankpin Diameter Standard	317.30 MM
3	Crankpin Bearing Width	210.00 MM
4	Main Journal diameter	330 mm & 317.30 mm
5	Main Journal Width	370 mm & 225 mm
6	Place of execution of crankshaft repair	Fertilizers & Chemicals Plant in India

On dimensional inspection of crankpin it was observed that crankpin nos. 02 developed excessive ovality. It also had deep line marks due to the failure of bearings which are of babbitt white metal type.
All the remaining crankpins were inspected and rough surfaces including bearing line marks were observed.
The main journal having a standard diameter of 330 mm also had a rough surface and required polishing.

**Damage of crankpin no. 6 of Compressor**

**Onsite repair of damaged crankshaft of CO2 Compressor**

**Picture showing before polishing of Main Journal**

Action taken by RA Power Solutions

Considering the fact that the main journal having a diameter of 330 mm having a rough surface and bearing line marks it was decided to remove the crankshaft from the compressor.

RA Power Solutions technicians submitted a drawing of V-Block which were manufactured in the factory for placement of crankshaft.

The grinding of crankpin no. 02 was undertaken and the final dimensions were maintained between 315.58 mm to 315.60 mm. The ovality of only 0.02 mm was observed.

All the remaining 05 crankpins were polished, removing the line marks and improving the surface finish. The surface finish after polishing was observed at less than 15 RA value.

All the main journals were also polished onsite removing the ovality to some extent and improving the surface finish again to less than 15 RA value.

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.

**Grinding of Crankpin by Onsite Crankshaft Grinder on Vessel**

**Crankshaft Grinding and Polishing Machine**

Suggestions:

RA Power Solutions strongly suggest that the polishing of the crankpin should be undertaken periodically as a routine maintenance process. This will not only extend the life of the bearings but also save the crankshaft from any major breakdown.
