Thread: Fairey Overdrive: S2A to S3 swap possible?

Hi Doug
Straight swap.
Basically only one model ever made.
Mods,OK here is a conversion a WA bloke did to his,Ian Lynne is the man.
The biggest problem with a Fairy in your gearbox is they have too smaller oil sump,they overheat the oil then feed the oil under pressure to the transfercase where its lost and not replaced.
Ian sliced the bum off the fairy and had a custom sump built so the oil dont boil.You need to find a competent alloy welder to do it but its a must do on the changeover.From memory Ian created a 2Lt plus sump!!! It also made it so much quieter!!!!
If you are after a spare overdrive and casing I have both.The input gear is stuffed as most are.
I bought the spare casing to do the above conversion but went big V8 instead.So if you want the spare housing to cut up and experiment with send an offer via PM.

Andrew what was the cause of overheating ? Long trips or just general driveing around ?
cheers Nev .

Faireys are well known for overheating and the expansion of the oil forces it into the transfercase thru the oil seal.It cant recoup the lost oil which results in the overdrive running dry getting more noisy and eventually its death.If you check and top the oil weekly not much of an issue.The expanded sump fixes the problem.
Andrew

Yes thanks Andrew.
The reason I ask is because I had an overdrive in my first landy a series 2A of about 18 years ,the overdrive in about the last 5 years of ownership. I used the landy as a everyday transport to and from work and general runabout at weekends and never had any trouble. ie no noise or overheating.
cheers Nev.

If you run a breather tube off the sheet metal cover plate (weld a 1/8" ID spud onto the plate) and run it up high into the engine bay with a one way fuel filter on the end you wont get a pressure build up that will force oil out of the O/D

Hey thanks for that Tank. I too am looking at putting a Fairy Overdrive in my SIII.

That mod sounds like the go to me.

I'm not familiar with the term "spud". What is it?

Fairey's were well known for having:
A high-pitched whine when engaged
Oil loss
Overheating problems
A fine-splined input gear with oil lubrication problems.

The toro OD doesn't have any of these problems. But try finding one...
