#1 Changing Rear Wheel Bearings, Finding Shims ?

This post started off about shims and morphed into changing bearings.

I did search around a bit before posting, and remembered with some pleasure the erudite, and generally well-mannered, exchange we had here :

viewtopic.php?f=3&t=15887&hilit=tapered+bearings

Irrespective of whether you're of the pre-load or end-float schools, they both depend on the thickness of the C.19110 series of 0.109" to 0.151" shims/spacers.

HOWEVER my usual SNGB regular is showing no availability on the sizes I was going to stock up on .............

And it's a row of three adjacent references, so there's no sign that re-stocking them is imminent.

Is there a better source for these, please ?

Hi Rory,
You might try Andy Rayner at Hutson Motor Co; Bradford, UK. I bought a couple recently from him and if you let him know what sizes you need, he may be able to help.

What size you after?

I have a stack of them, but am inconveniently located :-)

To be honest it wouldn't be very hard to make them...

Thanks for offers and advice, I have made them in the past but as both hubs are in the same ballpark it doesn’t seem to be a waste of 50€ to have H J K L M in stock and feel confident In the luxury of just opening a packet to dial in the perfect adjustment - a figure which stirs strong sentiment nevertheless.

Andy at Hutsons is looking to see what he’s got, tho if anyone had a drawer full I’d be all ears and cheque book.

Some thoughts on re-fiting the bearing tracks.

There's no need to use a press to do this, and many advantages in not doing so - far less risk of the races going in off-cock, and taking a shaving off the bore.

This DRAPER tool set could have been made for working on Jags, the two rings shown were perfectly sized for the rear wheel-bearings, and I've lost count of the number of times I've used them for other jobs.

I boiled the rear hub-carrier up as seen, froze the bearing tracks in the freezer, and the temperature differential means that the tracks just literally drop in. A tap on the centre drift confirms the dead-seating ring, music to our ears. The risk to be aware of is that when you do the second side, the first side may still be loose and can move.

Image

I use a drop of Loctite bearing-fit in contexts like these,just to be sure, but this method requires no peripheral hammering or juggling with spacers and anvils on a press that essentially gives you zero feedback.

Thought this might help/encourage others.
