Cracked Paxman 12YH Cylinder Heads

Cracked Paxman 12YH Cylinder Heads

In the workshop, at the moment we have some cylinder heads from a Paxman 12YH engine which are being overhauled in preparation for use on an upcoming engine work scope. The cylinder head overhaul consists of our standard process and following this meant we were able to highlight a couple of issues which would have caused major problems if any corners had been cut.  This is the procedure we follow: • Dismantle • Clean • Inspect...

Superseded Tooling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...

This is something we have come across many times before and seems to be a recurring issue, though with different causes, different damage and...

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...

Engine overhaul changes

Engine overhaul changes

We’re currently overhauling a complete generator set in our workshop. It’s one of four identical sets owned by the operator, and like a lot of operators, they usually operate under a service exchange programme, where one engine is replaced with another after a specified period of time. This time though, they’ve thought differently about the work scope to reduce the costs and disruption. As a complete package, we are responsible for the overhaul...
