Fiesta mk 3 gearbox oil change - pullgees
Itsa MK 3, 1.8 diesel, 5 speed. The drain plug on the gearbox has a little shaft protruding from it about 3" long, what is that and is it safe to take his thing out without upsetting anything?

on the inside ? Is it a magnet to collect any little bits of metal ?

Or a gear tooth stuck to the top of a little magnet ?

the drain plug on a mk3 fiesta gearbox is still on the drawing board
Do not take the long pin thing out
easiest way to drain these is remove a driveshaft
The oil will last the life of the box on a mk3,later ones ie mk5 have synthetic oil in them....

I presume it has a filler plug? If so the "long" way round is to syphon the oil out via a tube stuffed down into the guts of the thing via the filler hole. Took about 2 hours on my Escort, and felt better for having the 16 year-old oil removed, complete with shiny gearbox particles!

oldman is right (as usual). Removing a driveshaft and replacing it and new oil seal takes less than 2 hours:-)

From memory, that's the reverse gear detent cover (or similar), but think it can be used to drain the gearbox.

The Haynes manual decribe it as, "the selecter shaft cap nut and locking assembly" which can be removed to drain the oil. But is there a problem putting it back? I think syphoning sounds the safest option and in this weather the oil is pretty runny.

Oh no it's not! Unless our summers have got hotter than last year...

... 2 hours is small price to pay if you've got an afternoon free rather than jacking the car up and undoing supension components etc. But yes madf oldman is right, I only managed to get 2/3 - 3/4 out by syphoning, I deemed this enough though :-P
