automatic gearbox output shaft question

Post by almondgreen »

I have an automatic engine here.
This engine has hardy spicer couplings.
Are the output shafts the same as Cooper s ?

I have used auto Hardy Spicer units on a remote box before, worked fine, seem to remember I did have to do some lathe work on them but cannot remember exactly as was a long time ago now.

The output shafts in the differential and the flanges that bolt to them are the same. As are the bolts, the sealing washers (rubber/felt), the steel collets and the flat clamp washer.

The differential case (the steel part that holds the spider gears) and the spider gears, shaft and thrust washers are the same.

The gearbox side plate(s) are different between manual and auto as is the crown wheel and pinion.

The last of the hardy spicer auto boxes didn't use the cooper s output shaft that has the bolt in the centre to secure the flange to the shaft. The late ones used a 'knock on' version of the hardy spicer output flange, this fits to a pot joint output shaft in exactly the same way as a pot joint. It still requires the cooper S side plates as it retains the cooper s size bush.
I run a set of these on a Quaife diff.
