Case Study of Repair of MAK-1 8CM32C Engine Crankshaft In Burkina Faso, West Africa

The major details of the crankshaft of the MAK-1 8CM32C Engine are as follows:

i) Due to the repeated failure of bearings, it was decided by the client to get an audit of the crankshaft for all the major parameters. RA Power Solutions deputed two (2) technicians along with the onsite crankshaft grinding machine from New Delhi to Burkina Faso. During the initial inspection, the following was checked and observed.

a) The dimensional inspection of the crankpins was conducted, and excessive ovality was observed in all the crankpins. The readings for all the crankpins are pasted below:

b) As protocol, all the crankpins were checked for hardness by a portable hardness tester and were found within limits.

c) MPI was also undertaken to check the cracks, and no abnormality was observed.

ii) The grinding of all the eight (8) crankpins was executed onsite by our technicians. The first step size and tolerance of 0.02/0.03 MM were maintained.

Damaged Crankpin of Daihatsu 6DK-20	Daihatsu 6DK-20 Crankpin Before Grinding

On the visual inspection, the crankpin number #05 was observed to be damaged, and on the dimensional inspection, an ovality of 0.46 mm was observed. The readings are provided below:

Crack Detection through MPI	Crankshaft Inspection of Daihatsu 6DK-20

After the pre-inspection of crankpin number 05 of the Daihatsu 6DK-20, as per the protocol, which included dimensional inspection, hardness testing, and Magnetic Particle Inspection (MPI) for crack detection, grinding was initiated, since all parameters were found to be within acceptable limits. The Crankpin Number #05 was undersized by 1.50 MM.

Final dimensions are provided below:

We have to reduce the diameter by 1.5 mm due to deep bearing line marks.

Action taken by RA Power Solutions to repair the crankshaft of MAK 8CM32C :

RA Power Solutions deputed two technicians with an onsite crankshaft grinding machine, instruments, and necessary consumables.

Upon arrival, they inspected the crankshaft of a damaged diesel generating set of MAK 8CM32C.

The details of the job are as follows:

The dimensional inspection of the damaged and seized crankpin number #7 was conducted.

• Dimensional checks revealed:

Minimum Diameter: 279.68 mm

Maximum Diameter: 280.00 mm

Ovality: 0.32 mm

Apart from an ovality of 0.32 mm, the crankpin exhibited deep scoring marks and a rough surface, which was developed due to seizure of the bearing.

• The hardness was checked and showed marginally higher values in certain spots.
• MPI for crack detection was undertaken and revealed no cracks or abnormalities.
• The remaining crankpins were also inspected for taper and ovality and all within acceptable limits.

Action taken for the successful repair of the crankshaft of MAK 8CM32C :

i) The grinding of crankpin number #7 was ground to an undersize of 3 mm; this was done as the deep line marks were present at every step.
They got cleared only after grinding the crankpin to 3 mm undersize, resulting in a final diameter of 277.00 mm.

ii) The remaining crankpins were polished to improve surface finish and reduce the ovality by 0.01/0.02 mm.

The above job of crankshaft repair of MAK 8CM32C has been executed strictly as per the requirements of the manufacturers and the tolerance specified.

The details of the crankshaft of Daihatsu 6DL-16 are as follows:

Inspection Conducted by RA Power Solutions technicians and observations:

• On arrival, the inspection in detail was conducted by our technicians.
• It was informed that a local company based in Dubai was engaged to undertake the repair of two crankpins that were damaged.
• The crankshaft repair company based in Dubai took eight days to repair the two crankpins and the bearings failed twice within engine operation of 10 minutes.
• RA Power Solutions technicians did the dimensional inspection of crankpins. They were surprised to note that the crankpins after grinding by a Dubai-based company had ovality up to 0.12 mm against the maximum permissible limit of 0.03 mm by Daihatsu.
• The readings observed by our technicians before grinding are mentioned below:

                  SIZE OF CR JOURNAL                                     SIZES IN MM

• On further investigation, RA Power Solutions was informed that the company from Dubai had no specialized equipment/ tooling to undertake the grinding of Daihatsu 6DL-16 having a standard diameter of 120 mm and crankpin bearing width of only 64 mm. They did it by hand and were not able to control the ovality.

Action taken by RA Power Solutions Technicians

RA Power Solutions technicians after initial inspection for dimensions, hardness, MPI for crack detection, etc undertook the grinding of crankpins 1 & 4 and undersized both the crankpins by 1.0 mm.

The Final report after grinding is pasted below:

                     SIZE OF CR JOURNAL                           SIZES IN MM

It can be seen from the above readings that the taper & ovality were controlled within 0.02 mm. The engine was commissioned in the presence of our technicians and was operating satisfactorily.

Achievement by RA Power Solutions

The grinding of the crankpin of Daihatsu 6DL-16 needs specially designed, compact onsite crankshaft grinding equipment which RA Power Solutions has developed. This equipment is manufactured in two parts and is inserted from the inspection window of the engine block.

In this case, the crankpin diameter is only 120 mm, and the crankpin bearing width of 64 mm, we have designed the equipment that can undertake grinding/ polishing of the crankpin without removing it from the entablature.

We have been extending our onsite services all over the world for the last forty-three years and regularly work on high RPM engines like Daihatsu, Yanmar, Volvo, MAN B&W,  Caterpillar, Cummins, Deutz Engines, etc.

RA Power Solutions is ISO 9001:2015 (Quality Management System) & ISO 14001:2015 (Environmental Management System) certified approved company.

We have been regularly executing the on-site crankshaft repairs and crankshaft grinding in Dubai, Oman, Saudi Arabia, Qatar, Abu Dhabi, Sharjah, Ajman, Umm Al-Quwain, and Fujairah, Bahrain, Kuwait, Iraq, Antigua and Barbuda, Belize, Dominica, Dominican Republic, Grenada, Guyana, Haiti, Jamaica, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Trinidad, and Tobago, etc.
