Thread: Fairey Overdrive whine

They are usually pretty noisy i'm told, although one member mentioned that an oil stabiliser like moreys helped keep it quieter.

Mine was pretty noisy and it was in when I got the truck. I imagine going from not having one, to putting one in, then it must be really noisy. Kind of like going from a V8 to a 300tdi.

Are they usually noisey ??, if not other that stripping it down is there any other fix.

As suggested, it is said that an oil stabiliser such as Morey's helps. They are usually (I'm told not always) noisy when in overdrive, but should be no noisier than normal in direct. All parts are available and most of the bearings and seals are available from bearing suppliers. Apart from the bearings and seals, parts are quite expensive. Overhauling is not particularly difficult. They apparently function for a long time while making an awful lot of noise, so the noise doesn't mean it is about to fall in a heap.

Are you sure it was the fairy overdrive that was whining and not SWMBO??

I used Morleys in mine else the oil would be nearly boiling on a long trip. Mine was an early one obtained 1979 and lasted until I sold the Land Rover Se 3 20 years later. One overhaul was required as the bearings at the back did not get sufficient oil (design problem) and I was told that my version had the gears cut differently from later models. I did sound proof the cabin which did cut down the noise a fair amount in that you could carry on a reasonable conversation.

Thanks to all for the feed back I will the Morey's a go.

The Fairey ODs are very noisy. The Toro ODs (herder to find) are a lot stronger and much quieter.

So I believe - but I've never actually seen one! Apparently they DO exist though, and have the lubrication system a lot better set up than Fairey do, as well as being generally more rugged.
