Thanks Dave. I will have a look. Though I am a little afraid of e-bay....

Hey Johnno,
I've got a 2a running series 3 running gear (2.25 petrol), and the wonderful Fariey OD. Much the same as you, i am growing quite tired of the WEEEEEEEEEEEEE!!!
I have the plesure of having a ute cab, wagon roof and soft-top for it, so I can choose my level of OD loudness (ranging from normal to loud). I am quite happy to not muck around with it as hey, it works! But I believe that when the time comes that I get completely fed up with the whine of the straight-cut OD gear noise, I am going to go to a custom gear manufacturer (such as Albins in Victoria, maker of brilliant racing gearboxes, and capable of doing damn near ANYTHING with a gearbox) and having them make me up some helical or double helical gears for the Overdrive (and perhaps transfer case if required). Expensive yes I know, but it will stop the noise at the source.

Hi Lachy,

Most of the noise comes from the gears not meshing well because they are pretty agricultural - your idea would probably solve the noise issue but I think the cost would be more than a high speed T'case and a fully restored series landrover to fit it into!

Cheers,

Adam

We tried to fix this back in the 80s using the latest synthetic oils etc.
At that point the oils made no difference the splines on the input will eventually fail and your world will be much quieter.
I have never seen a Fairey in even near new condition be quite.

A friend of mine wrapped his is fairly thick lead sheeting...seemed to kill some of the noise.

Hey Lachy,

Yeah, that'd be good. I know what you mean. Expensive, but just imagine all the silence that money could buy! Like you, I put up with mine becaise it works and has been doing so for twelve years.

Cheers,

John

I've thought about lead before, actually. Might look into that.

Thanks,

John

Yep, I got mine brand new from the UK, and I can't ever remember it being quiet. I think it got a bit noisier after I once ran it rather low on oil (oops), but it's never been quiet. I've recently replaced the input. The old splined were nearly cactus after a handful of years of running. I have always carried the original input gear, nut, washer etc for the transfer just in case. Now I have a spare overdrive input too...

Cheers,

John
