Paxman Engine Flywheel Modification

Paxman Engine Flywheel Modification

What speed do your engines run at?

1500 RPM, 1800 RPM, or more?

Whatever speed it is, the potential damage or injury caused by something coming off the engine is huge.   Unfortunately, we’ve seen first-hand the damage caused by the starter ring coming apart and flying off the flywheel.   And I can tell you that it certainly wasn’t pretty!!   As you’d expect, following the incident, the client highlighted it as “major” and brought us in to conduct a full investigation into why it happened, and how we could prevent it happening again.   We’d worked with quite a few engines of this type before, so we were quickly able to identify the change of the starter wheel fixings from special studs to set bolts.   This was a change which the engine maker had designed, so the operator couldn’t have been expected to pick up, but in this instance, it caused a major problem. To fix the problem and reduce the risk, we machined the flywheel to accept the original fittings, so our client could use those instead of the newer set bolt arrangement.

In an ideal world, these types of risks would be engineered out before the engine is installed, but the complexities and varieties of engines make it difficult to protect against every single eventuality.   And consequently, that’s where the ability to tap into extensive engine experience becomes more important and gives you and your engines better protection.
