I second that. This is the way to go!

Columbia Two Speed has the good races!

Thanks all, It seems from pouring thru online catalogues, the standard bearing inner sleeve I seek isnt actually made, so Ill give John an email.

Thankyou everyone!

Since I'd retired, John has done all of mine. Always top rate quality at a reasonable choice. You won't go wrong with the man...

This is one I did a while back with a full bearing brought of the shelf , The hub race on the axle is a slid fit no machining needed except it needs a sleeve on the OD of the Axle . also a thin sleeve on the ID of the hub ,I have no significant miles on it as yet ,Merc 42 maybe a better way .

I do a similar mod but use two NU 1010 roller bearings, machining required, one good thing is the old axle tube bearing area only has to go down to 50mm .
machine the hub bearing area true, press in a sleeve ,then machine to 80mm
Have done two ,
the roller bearings take WAY more load than a ball bearing, the 2 NU 1010 take a static load of 9500 KGs per side so they will handle 19 tones on the back end .
Also the speed of the rollers is way slower than a needle roller.
BUT they are costly.
I have a set on my bench now so will post some pics, or look up a post I did way back on them .

I have just done the second bearing repair mod for my spare 33 rear end.
This fixes the worn bearing area in the hub and on the axle area also.
I machined the hub out to 82.5 mm, then shrunk in a sleave, bored that to 80mm.The hub was easy to machine out after I used a new insert on the boring bar. BUT it is very hard.
machine the axle OD down to 50mm and press on the bearing inner.
The bearings are two roller ones with a total load capacity of 9.6 tons each side and a limiting speed of 9500rpm ,so should be safe there.
Only draw back of this, I have to remove the brake drum from the hub to machine it as my lathe is not quite big enough to do it with it on.
