Pot joints
Turbo Mini Forums

There seem to be two types of Pot-joints out there. One bigger, and one smaller.

When did this change come, and what are the differences? Just the balls, or the entire thing?

Yes I have come across this in the past. The balls are the same I think, just the cage is bigger and the outer housing machined differently.

Not sure when or why they changed, I thought possibly the bigger ones had been re-manufactured to recon them hence new cage and inner race and remachine the outer?? But now I have seen that many of them in different cars that it must have been something BL/Rover did from the factory.

Yeah i got caught out by this, spent ages trying to get a drive shaft/cage/balls etc in a pot joint until i realised they were a different size.

I thought i wasnt getting it correctly aligned!

its not the difference between metro pots and mini pots is it?

Have heard the same Dan!

i was looking at an online cv supplier and there was no difference between metro and mini CV in terms of part number but then again it was a complete unit

hey, never knew this! Wonder when it did happen - maybe when the metro was launched with its potent 63hp 1275 engine???

LOL!

its not really that noticeable, hence struggling for fooking ages!

I can imagine myself doing the same! (not now i know this however!!!)

I've just been out in the garage measuring pots.. There are indeed two different types. The difference I've noticed, is the size of the ring holding the balls. This is of a bigger diameter on the new ones resulting in that it does not enter old pots. I've taken some pictures but forgot my camera.... DOH!

Update shortly.

Vegard - post the different dimensions aswell!

I haven't taken any measurements yet, but here are the differences:


One could clearly see the difference in size and shape on these two.



The difference on these, are that there is a slight 45 degree angle on the area between the balls on the "smaller" one.

I tried to see if there was a correlation between the wide and narrow gaiter recesses, but did not find any solution on this.

I do think that the balls are of the same diameter.

What we now need to know is when this change was made, or if it's just a Mini/Metro difference.

Digging this up as i have come across it today.

Went to fit my complete disk brake set up (including driveshafts from an 85 mini) to my drum braked estate (1978), and found the pot joints are a different size, which has messed me right up!

So when do we think this change over happend?

Nearly five years... New record? :)

I seriously doubt it!

Yeh Vegard its usually you that does the digging lol:)


I thought it might be the difference between 1000's and 1275's ?

I've had this problem a couple of times.

BTW - I took my buddy VTEC Pete out for a spin this weekend, and even though I am running her in, he gave it a name, the "Brocket"...cause I'm a brocket maaannn, nah nah nah nah nah nah nah nah nah nah nah....

I must say that now I know that the pot joint can be knocked off the shat without too much hassle, I keep them as a complete sealed unit, and don't pull them apart.

maybe its the difference between pot jointed disc setup and pot jointed drum setup

I wouldn't be surprised if the smaller joint uses inperial balls and the bigger are a leter upgrade to metric,
