OB Gear box Flushing

[jimbouy]

I've just got hold of a secondhand gearbox and lower leg portion to replace the knackered one on my also secondhand and rather shabby Merc 2.5hp.

I've drained the gear box oil and it was black and horrible but not gritty in any way.

It would seem a good idea to flush the gear box with something first..... but what with?

Or should I really strip the whole thing down and do it that way?


Any thoughts guys.

Parafin

I was told diesel by the local ob dealer

Parafin has indeed done a grand job....

Cheers

Diesel is fine, but parafin leaves less less of itself behind.

Make sure you let all the paraffin drain out before refill as you do not want it diluting the oil.


Also please note one r and two fs. From the Latin parum affinis. You should all have learned that at school!

Well drained, but I also intend to "flush" a small amount of leg oil in there prior to filling up proper.

Actually the bottle says Parasene...... /forums/images/graemlins/smile.gif

[/ QUOTE ] Only if what drains out looks really 'orrible. Personally i would flush with some light oil, cheap engine oil perhaps rather than paraffin
