Engine Idling Issues

Engine Idling Issues

We are currently overhauling a Napier MS90 turbocharger from a marine operator’s Mirrlees Blackstone engine. The engine has just over 12.5k hours on the clock and is in good condition, however, the turbo was on the radar as needing some attention. Once our engineers had removed it and sent it to the workshop, the overhaul started with the usual inspection, dismantle and clean. As part of the overhaul, we knew the labyrinth seals and...

ABB VTC 254-13 turbocharger overhaul overdue

ABB VTC 254-13 turbocharger overhaul overdue

I often mention the importance of having bespoke service plans tailored to your critical diesel engine, suited to its application and environment. And a recent work scope showed how vital this is for the turbocharger as well. We currently have a couple of ABB VTC 254-13 turbochargers in our workshop for full dismantle and report. Both have issues that could have been prevented if a more suitable maintenance schedule was in place rather than the...

Seized turbocharger back on-line

Seized turbocharger back on-line

If you are reliant on “heritage” engine models, or those simply not made anymore, then chances are you will have experienced supply problems for ongoing maintenance or repairs. Sourcing of spares can usually be overcome with a bit of digging, but when it comes to major assemblies, it can be a lot more complicated, not to mention expensive! One of our clients found themselves in that position recently with two Sulzer LAG46 Turbochargers that had...

Superseded Tooling

You may remember that I shared some information on a couple of ABB VTC 254-13 turbos sent in for overhaul and repair, one of which was cracked. If you missed it, you can check it out here. We’ve continued work on this overhaul and we’re now completing the rebuild, during which we came across another challenge which the OEM had solved (though on a different model). One of the turbochargers required a new turbine wheel and shaft with a new...

Incorrect compression ratio

Incorrect compression ratio

This week we are working on a Mercedes Benz 400 series engine which is used in a crane on an oil platform. The engine had been experiencing problems resulting in cracked manifolds and turbocharger housings which is why it’s in our workshop, but during our inspection of the supplied spares set, we’ve been able to prevent another problem. Originally the engine had been taken out of service by another company who had ordered a set of spares for...

Turbocharger Damage

Turbocharger Damage

We have two ABB VTC 254-13 turbochargers being overhauled in our workshop and they both offer a stark reminder of what could be going on, unseen, in many operational turbos. I haven’t got information on the history of these turbochargers, but they’ve been sent to us as part of an engine overhaul and I thought it was worth sharing what we found: • Considerable damage to the compressor wheel blades. Some material has been removed and blades...
