  • Crankshaft recovery – machining and polishing

  • Cast iron recovery – metal stitching, metalocking

Crankshaft recovery

Recovery of crankpin or main journal – in-situ machining and polishing

Our recovery specialists can recover a single journal or an entire crankshaft. Employing the most effective in-situ machining methods and specialized tools, we remove hardness and cracks from affected areas. Superfining and hand polishing ensure a perfect surface contact to the new bearings. From measuring to testing and blue marking, we perform quality assurance through all recovery stages.

Main bearing saddle recovery – in-situ machining

Fixing the geometry of the main bearing saddle after a bearing failure can take an engine out of service for as long as six months.  We can save you valuable time by machining your main bearing saddle in-situ in your MAN two-stroke engine – we are the only team worldwide capable of doing so.

Customized recovery solutions

Our solutions are as outstanding as the challenges you face

In addition to the recovery solutions in our comprehensive portfolio, we also tailor solutions for customers facing a more unique challenge. Whether it’s the scale, complexity, or subject-matter that’s unusual, the common denominator is a damaged – or faulty – large metal component or construction that is difficult to replace or transport to a workshop.

A powerful combination of experienced on-site specialists, technical design and specialized tools

We are uniquely suited to tackle even the most unusual tasks. We assess the challenge, come up with a solution, even develop the tools, if required, and do the job fast, effective, and on-spec. Challenge us!

Fully operational engine in just two weeks despite ridge wear on every crankpin

MAN PrimeServ On-site Recovery helped a customer remove ridge wear on a small-bore four-stroke engine. All six crankpins showed ridge wear to the degree that required machining. At the same time, however, the repair was to remove as little material as possible. A team of four on-site recovery specialists successfully removed one millimeter of material from each of the six crankpins. After in-situ machining, we polished the crankpins by hand, tested for roughness, and blue marked to assure sufficient contact surface to the new undersize bearings.
