Hi,

Has anyone fitted a Fairy Overdrive on his original Series 1?
Q1) When did Fairey Overdrives came into production?
Q2) And how would my original engine and gears handle the overdrive?

Any feedback would be very welcome.

1. Not certain, but I'm pretty sure it was during Series 1 production, probably about mid fifties.

2. No problem with the gears handling it, engine? The 2 litre should be OK on an 80, 86 or 88, but would struggle on a 107. Probably not a good idea for the 1600. But lack of power would simply mean you use it less in fourth gear - don't forget it also provides a split between 3 and 4, for those hills where fourth is too high but you would like a bit less revs in third.

Oops...

Question 3:
Will any Fairery Overdrive fit my S1, 2.0 ltr, 88", or are there differences?

Maybe stupid questions but this is the first time I am looking into an overdrive and I saw one for sale. (Not sure if I can afford it. Anyone wants to trade or donate?)

Thanks,

Kris

You will need a series Landrover overdrive - Fairy also made them for Toyotas and the O/d on a landie LT95 gearbox is different again.

There are companies other than Fairy that also make O/d that will fit your vehicle.

I have had one on my '56 2L since 1975. Works very well for most driving. Standard engine struggles on hills, need to go back to 4th.
For long drives on the level it is an eardrum saver, can happily cruise at an indicated 60mph.
It was my daily transport for 15 years.

Some people had problems with early Fairerys, but the S1 doesn't put enough torque through to hurt it. Mines still ok anyway.

Watch the oil level.

edit- the S1 gear ratios are are different to S2, no gear split available, step up 3rd to 4th is the same as the O/D step.

The same overdrive fits all Series Landrovers except One Ton and Stage 1 - although I am not sure about early 80".
