Crankshaft Machining | Crankshaft Repair of Wartsila 6R32 | DUBAI
RA Power Solutions is India's only company with 46 years of experience in crankshaft repair, machining, and ship crankshaft machining. We specialise in onsite crankshaft repair for sizes up to 700 mm. Our team has successfully saved over a thousand Wartsila crankshafts from rejection and is well known for restoring even heavily damaged Wartsila crankshafts.
The main specifications of the crankshaft/engine of Wartsila 6R32 are as follows:
The crankshaft of Wartsila 6R32 was reported damaged by one of our clients based in Dubai. Our team of two technicians travelled to Dubai and boarded the vessel.
Our technicians immediately inspected the damaged crankpin no. 05 of Wartsila 6R32 upon arrival.
We observed an ovality of 0.18 mm in crankpin no. 05.
Bearing line marks due to the seizure of bearings were observed on the crankpin diameter.
All other parameters, such as hardness, deflection, and MPI results, were observed to be satisfactory.
Machining of crankpin no. 05 was undertaken to 0.5 mm undersize.
In this case, the radius profile was observed to be damaged during the initial inspection. The part was repaired, and the radius fillet profile was maintained as original.
The complete job from inspection to repair of the crankshaft of Wartsila 6R32 was executed while sailing the vessel from Dubai Port to Amman Port, Jordan.
We use a specially designed crankshaft grinding machine to execute the repair while sailing the vessel.
The machine absorbs the vibration and is capable of maintaining tolerance in terms of taper & ovality within 0.02 / 0.03 mm.
