The major technical details of the MAN B&W 5L 16/24 engine and crankshaft are as follows:

On inspection of the crankshaft it was observed that one number crankpin developed excessive ovality of 0.59 mm and bearing line marks were observed. All other crankpin dimensions were checked and found within limits.

The one-number crankpin grinding was undertaken by RA Power Solutions technicians with a patented portable on site crankshaft grinding and polishing equipment carried by them & crankpin was undersize by 1.0 mm, maintaining the final dimensions of crankpin of MAN B&W 5L 16/24 as 129.00 mm and have saved the crankshaft of MAN B&W from rejection.

Our client, a leading shipping company based in Hong Kong, invited two companies to repair the crankshaft of MAN B&W 5L 16/24 from Singapore. The companies could not undertake the repairs as the grinding of the crankpin having a small crankpin width of only 58.50 mm required compact and special tooling which can be accommodated in a small crankpin width dimension. The removal of the crankshaft and sending it to the workshop was suggested to the client, which was not possible.

RA Power Solutions by undertaking the onsite grinding of crankpin saved the crankshaft from rejection and the vessel sailed within 9 hours of boarding a vessel by our technicians in Trincomalee port, Sri Lanka.

Availability of Undersize Bearings with RA Power Solutions:

RA Power Solutions deputed the technicians with 0.5 mm and 1.0 mm undersize bearings and after grinding 1.0 mm bearing was assembled and the engine was put back in operation.

A great saving by the ship owner with a cost-effective solution given by RA Power Solutions.

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

Introduction of revolutionary onsite crankshaft grinding machine

With the introduction of portable onsite crankshaft grinding machines, it becomes easy to undertake repair of crankshafts onsite without removing them from the engine block. This introduction of onsite crankshaft grinding machines was of great assistance to shipping companies, diesel power plants, and various industries as they could get the crankshaft repaired on their premises, and they saved in terms of time and money.

Onsite crankshaft grinding monopoly of a few companies

It was observed by the shipping and industries in general that the cost of onsite repair charged by a few of the European-based companies was exorbitant and they were using unfair business practices. RA Power Solutions introduction of onsite crankshaft grinding and crankshaft polishing machines do it yourself.

RA Power Solutions has been manufacturing onsite crankshaft grinding machines for the last fifteen years in technical collaboration with a leading Italian company. The machine is very easy to operate and maintain. Machines are manufactured in the range of 35 mm to 700 mm diameter. By providing onsite training to our clients and technicians, they can operate the machine of their own. It is observed that in most of cases, if the crankpin and main journal of the crankshaft are polished from time to time, the failure of the bearing and crankshaft can be controlled to a large extent.

“Do it yourself” concept

The technicians onboard a vessel can undertake the polishing of crankpins and main journals of their own. We have several clients using our onsite crankshaft grinding machines undertaking the polishing and grinding of the crankshaft of their own and stopped paying huge amounts towards the repair of the crankshaft.

Technicians available 24*7

We recommend our clients to undertake crankshaft polishing under the slogan Do it yourself and save money. The charges for the deputation of our engineers are very low and the crankshaft can be repaired with considerable minimum cost. The concept was launched by our managing director Mr. Raj Shahani who has been working on crankshafts for the last 41 years. He is a technical adviser to various shipping and heavy industries based all over the world.
