Wärtsilä 16V32LN Engine Crankshaft Repair at Diesel Power Plant in South Africa
One of South Africa’s leading power generation companies approached us for an urgent Wärtsilä 16V32LN engine crankshaft repair. The company has several Wärtsilä diesel generating sets that it uses for power generation and to supply the government-regulated power grid.
One of their Wartsila 16V32LN diesel generating sets had a serious breakdown due to a damaged crankshaft. The damage on the crankshaft was mainly observed on crankpin no. 02, which required immediate inspection and repair at the site.
Action taken by RA Power Solutions to repair the crankshaft of the Wärtsilä engine 16V32LN
Two experienced technicians arrived at the power plant in South Africa, equipped with the necessary inspection instruments and a crankshaft grinding machine, to be used on site.
During the first inspection, particles were found inside the sump below crankpin no. 02. The technicians opened the connecting rod and found that overheating had badly damaged the bearing.
The main dimensions of the Wartsila Engine 16V32LN crankpin are as follows:
Inspection Findings of Damaged Crankpin No. 02
Crankpin no. 02 was carefully inspected. The following observations were made:
Crankpin no. 02 showed ovality of 0.08 mm to 1.25 mm.
The crankpin hardness was checked and found to be on the higher side. However, in the location and condition in which it was found, it was not deemed to be detrimental to the satisfactory operation of the crankshaft.
Crack detection was performed by Magnetic Particle Inspection (MPI), and no cracks were detected.
Crankshaft deflection was checked and found to be within limits.
The other remaining crankpins (crankpins nos. 1, 3, 4, 5, 6, 7, and 8) were inspected and found to be within acceptable limits for ovality.
Bearing line marks, rough areas on the surface and water marks were found on several crankpins.
It was recommended that the remaining crankpins be polished to restore a smooth surface finish.
Crankpin No. 02 Measurement Before Grinding
Crack Detection of Wärtsilä 16V32LN Crankpin
The damaged crankpin was inspected using magnetic particle inspection (MPI) before machining. The importance of this inspection after bearing failure or overheating is that it can detect surface cracks due to excess heat or abnormal loads.
No cracks were found on the damaged crankpin.
Onsite Crankpin Grinding Wartsila 16V32LN
Because of the condition of crankpin no. 02, on-site crankshaft grinding was done with a specially designed portable crankshaft grinder.
The damaged crankpin was machined to an undersize of 1.5mm. The dimensional tolerance required in the grinding operation was maintained within 0.02 mm.
Crankpin No. 02 Measurement After Grinding
After grinding, the crankpin achieved a surface finish of approximately 0.16 Ra.
This confirmed that the crankpin had been restored to the required dimensional accuracy and surface condition.
The photographs of crankpin no. 02 after grinding are pasted below:
Polishing of Remaining Wärtsilä 16V32LN Crankpins
The remaining crankpins were not machined since they were within limits. However, the crankpin surfaces showed bearing marks, rough areas, and watermarks.
Therefore, all remaining crankpins were polished by a purpose-built onsite crankshaft polishing machine.
The crankpins were polished to achieve a surface finish of <0.20 Ra
Final inspection and engine starting
After the crankshaft grinding and polishing work was completed, final dimensional checks and inspections were made.
The ovality of the repaired crankpin no. 02 amounted to only 0.02 mm, while the other crankpins were also within the acceptable limits.
The engine was then commissioned in the presence of the technicians and found to be in satisfactory working condition.
Benefits of Onsite Wartsila Crankshaft Repair
The Wartsila 16V32LN crankshaft repair was performed at the power plant without removing the crankshaft from the engine.
Advantages of Crankshaft On-Site Repair:
There is no need to remove and take out the whole crankshaft.
Less engine downtime.
Speeding up the restoration of the generator set.
Good for emergency crankpin repair.
Grinding, but also dimensional inspection before and after.
Crankpin grinding and polishing can be performed on-site at the engine.
Helps cut down transportation and replacement costs.
