[Fot] Fwd: TR6 inner shaft bearing

Tue Apr 14 06:37:57 MDT 2020

Hi Bob, 
Is the collar really preventing the stubaxle from being pulled out? I think that the small bearing housing (the one bolted onto the diff case with 4 screws) is doing that by keeping the outer bearing ring in place? Then , if the bearing can slide on the half shaft, the half shaft and flange can move outwards. I suppose the normal position of the bearing is against that collar. I'm talking about an TR4a IRS : maybe all IRS diff's are not the same : on a TR4A that collar is pressed upon the half shaft not machined and the bearing is on the diff side of the collar.

Hi, 

It's funny how some things seem to happen coincidentally - I had a customer car in the shop this week with a leaky stub axle. I had a re-conditioned stub axle on the shelf and bolted it in. The seal was clearly not riding on the axle seal surface. I took a test spin and "leak city". Pulled the stub and re-positioned the bearing away from the collar on the axle by about 1/4" to 3/8" (around 6 or 8 mm) and bolted it back up. Leak-free! 

The bearing moved fairly easily on the shaft. 

The flange, on the other hand - I have had them on a press and used 30 tons of force and the stub and flange did not separate. Note that when you use a press, do not use a universal collar to support the flange or you will bend the flange. 

Regarding whether there's a"fix" for the bearing walking on the shaft, the answer is: there's a collar machined on the differential side of the stub axle that keeps the axle stub from pulling out and if forces try to push the stub towards the differential eventually the bearing bottoms on the output flange. But that stub position can move around a bit. 

Good luck! 

Regards, 
Bob Lang

I discovered a couple of times that the bearing did move on the shaft by as much as 1/2". As a result the shaft had moved outwards by that amount. Is that common? Is there a simple fix?

the flange fits on a tapered shaft which is the bear...the bearing doesn't take much at all...if you do happen to find a shop that can get it apart for you make sure you make a note of the bearing position on the shaft...take a measurement before you press it off for reference. I use a 50 ton press to get the flange apart...usually takes at least 20 tons...sometimes more...always wrap a towel around the assembly...dont think I've ever had one i couldn't get apart.

Hah! I just attempted that this week. The two stub shafts would NOT press out even with 10 tons and red hot from my firewrench. Scott Harper at Team Triumph came to my rescue and went through his stash to find a couple that did press out for him. So give him a call if you can't break them apart. Good Luck! Jay WPTA

How much force is typically required to separate the driving flange from the shaft
