Successful Running of BR Class 17 D8568

[Greg Wetzel]

I was reading about the BR Class 17, and how only D8568 is preserved by the Diesel Traction Group. But I'm struggling to learn what they did to make D8568 work successfully after many years of problems.

It's always easier to maintain something when you can spend quality time on it, with quality staff and the duty cycle of the loco isn't too onerous.

In the case of D8568, one particularly excellent former OOC fitter (who later became a riding inspector) has been one of people keeping it going.

Much of the problems with them was attributed to the alloy crankcases which BR insisted on against Paxman's insistence that steel would be better.
Anyone know what version of the engine D8568 uses?
