MTU 396 Crankcase checks

Crankcase Checks

Engines

08/02/2018

Last week we shared a post about an MTU 396 engine having to be removed from its location to our workshop for an overhaul. (If you missed it, you can read it here).

The overhaul’s in full swing, and today we’ve carried out some testing rarely asked for by our clients.

During the inspection process, you’ll be aware of the various measurement and crack detection checks, including the pressure testing of the cylinder heads, but have you been involved in this type of testing?

This pressure testing of the crankcase was requested to check there wasn’t any internal damage to the complicated water system.

The alternative would be X-ray, but on an item of this size, that would be a very expensive option!

The focus is usually on the pistons, rods, bearings etc, but as the crankcase is such a fundamental part of the engine, that needs to be thoroughly checked as well.

If there was any internal damage, it could easily result in significant downtime and problems from an engine seizure.

The pressure test proved there wasn’t any internal damage, so the rebuild could continue, but that’s given added confidence in the future of the engine and all for only an extra 2 hours.

For me, it’s refreshing that our client requested it themselves – it’s great working with people who have the same high standards as Bartech.

Are there any testing regimes YOU insist on?
