Gearbox cleaner

Jizer works very well to remove oils and greases.

Diesel works well. It also lubricates so you may be able to run the system on no load with little risk of damage. That's your decision though :-)

John,

That's a very interesting thought, especially as I happen to have a couple of litres of diesel in the workshop. But.... what do you mean by "run the system on no load" - do you mean drain oil, fill with diesel, and run on no load for a while to clear the gunge? If so, sounds a lot more attractive than taking down the feed box (which involves partial removal of the leadscrew).

That's just what I meant. Run it fast enough (if possible) to throw the diesel around inside but slow enough to give the bearings etc an easy life. In theory, the gears and shafts should throw the diesel just where they throw the oil that's causing your problem. You used to be able to buy flushing oil for cars that did the same thing before detergent oils came along. As I say, it's at your risk though.
