To get that lower bearing off, I use a chisel and split the bearing cage, it gets all the rollers out of the way. Now you can clamp the lower clamp in a vise with soft jaws, and drive the race off using the chisel against the upper lip on race. You can warm the inner race with a propane torch, most of the time it's not necessary

Hi Don,

Congrats on getting it apart.  I replaced the seals and cartridges in both the LMIII and Monza and they were very similar.  If the T-4 is the same the second page of this topic may help:

Thanks Shawn,

That link did show some interesting stuff on how to dismantle the fork tubes for rebuilding.

Cheers

Tonight I completed the last little bit on the steering stem disassembly. I removed the lower inner bear that was on the lower end of the steering stem. I prised the bearing retainer outwards until I had distorted it enough to snip it with the tin snips. Then pulled it away so all the rollers could fall out. With that removed I then  took to the inner race that was pressed onto the stem with a small angle grinder. I only had a cut-off wheel though and not a wider grinding wheel which would have made the job easier.

I persevered with the cut-off wheel and went a bit deep in a couple of places but got it off in the end. See following pics.







Now I am waiting on parts to arrive before I can do any more work. Or maybe I could pull the front forks apart and see how they work.

All good times ahead.

Thanks for all help offered.
Cheers

The only other way is to press the shaft out of the lower tripple clamp, the hammer approach will only knacker the threads or bend the shaft. Guess how I found out.

I knew a piece of wood on top would work, sure you prob mangled that wood but it's a hell of a lot less danger of damaging the steerer than even brass plate  :thumb: 
I have done the same on several old bicycles when I was wrenching at the co-op and it always worked fine.
