Thread: Difficulty with Fairey Overdrive

I run Moreys in my overdrive, but I don't think it really makes a significant difference. Note that one thing I have done is to extend the breather up about three centimetres to stop it chucking oil out - I enlarged and tapped the hole and fitted several brass fittings topped by an axle breather fitting off a Series. Seems to have stopped it, although I have just replaced the gasket on the top plate, which was leaking.

Thanks John. I might look at doing the same, see if I can find something the shed I can use for a breather. I might not be able to go so high as I have a tool box tray in the middle seat which comes down about 4 inches. It's got plenty of clearance to the gearbox as it is but will have to see if how high I can go.

So have I! I did not give full details - there is a right angle bend screwed into the plate, then two nipples to carry it left to past the tool tray, then another right angle, then another two nipples, then the breather. Depleted my tin of brass pipe fittings, but it seems to work. I suspect it does not need to be very high, even a centimetre or so would probably help.

Hi All,
I am about to fit a Fairey O/D i picked up on Ebay to my 1958 Series 1 109 inch ute. I see mentioned that oil get chucked out of the breather which is just a split pin by the looks. Do they also leak oil into the T/fer case . I read above to always carrry the original parts and will do this just in case. Any other info or tips greatly appreciated.

Hey Elvin,

If you do end up doing any more work on the overdrive itself, I managed to source all the parts when I reconditioned mine (mind you, I still haven't used it yet...) - and I got a lot of them substantially cheaper than mobs like Rovers Down South charge (some expensive items were literally one third of the "usual" price people quote).

I can't add much more than those who have already replied - except that I know a good type of soundproofing as well...

Send me a PM if you need any of the info.

Cheers,

John
