Hardy spicer couplings

[rolesyboy]

Seen a set on e bay and wondered if the will be a direct swap for the rubber couplings/yokes I have on my car at the moment? 22g1128 Gearbox with remote housing. Do they just push on the diff splines and on regular driveshafts? Cheers.

You need the rest of the parts as well as the coupling's, eg side covers and diff output shafts.

Ok, great, Anything else? Can I buy any old side covers and how do they differ?
Cheers

The side covers for the Hardy Spicer shafts are of a larger bore size, so I'm afraid any old side cover won't do.

I've got a set of Hardy Spicer couplings that fit standard diff covers. Home made?

Because I actually have English minis I'm not totally familiar with the Oz versions - But I believe we had two kinds of HS joints - that were indeed different. One kind for the S and the other for the Mini.matic..

you can use std side covers if your stuck, simply machine them out to accept the larger bush. the material is a little thin, so it doesnt offer as mush support to the bush as the proper 22g420's do, but it will work - people have been doing it for years.

on autos, the hardy spicers are the same (and worth hunting down, as they never get the hammer the s ones do!), its the output shafts that differ. the oututs can be fitted to a normal pot joint diff to convert it to hardys. they make getting the engine out easy as you dont have to undo the philidas nuts, you just treat the hardy spicer and the output shaft as a 'pot joint' and knock it past the snap ring.

There are some hardy spicer output flanges around which fit the standard mini output shafts, identifiable by a chamfered edge and no internal groove for the split collets used on the 'S' and auto. I've seen a few of these on e-bay being passed off as 'S' ones, and I bought a pair at an autojumble thinking they were the correct ones. The flange outside diameter is the same as the 'S' and will need the the 22G 420 side covers, or the standard covers can be bored out and fitted with the larger bush. The driveshafts on H/S type cars are 5mm shorter than the rubber coupling type to allow for the extra width of the H/S setup.

I bought a set of push on H S outputs from min-e-bitz, and then got a machine shop to lathe them down to fit standard output covers, but I made sure the bushes were in good condition and had the outputs matched to each cover with there right tolerances.

those are the auto ones, the later autos have a welch plug in the end and a groove machined inside for the snap ring on the pot joint output shaft (so they look just like a potjoint, but with a flange end rather then the cup for the balls)

i think (distant memory) that the first autos used the ones in your photo with the rubber coupling type arangement of holding them to the diff - these will not be any use for quick removal, but would be fine for a 'normal' car wanting to use hardy spicers.


ive never seen an auto that used the bolt & collet type fixing arangement that the proper s output flanges use.

the side covers from an auto are unique to the auto box and cannot be used on a manual, only the hardy spicer flanges outwards are any use/value

When I fitted a H/S set up on my S replica, I bought an automatic diff assembly which had output shafts/flanges with the split collars and bolt. If I remember correctly all I did was change the final drive assembly to the ratio I wanted (3.1:1). For the diff covers, I had some standard covers machined out to take the bigger bushes and have so far had no problems.

Previous to buying the auto diff, I bought an assembly that had had the diff welded for auto cross (?) racing. The h/s flanges had been machined down to fit into the standard covers.
