RE: Morons - Ruairidh Dunford - 30-05-2019
I cannot comment Tony - I don’t use tapered bearings, sorry.
RE: Morons - Hedd_Jones - 30-05-2019
surely the simple fix is to turn the stub square to fit an off the shelf bearing, or if not possible fit a sleeve so that it is
RE: Morons - Bob Culver - 30-05-2019
Sorry to labour this for no other point than curiosity, but was the welded bearing a proper taper one? When the photos revealed a tapered stub I presumed the welding was to seat a conventional bearing?

You can turn a square?
Blimey Hedd, that must be a clever lathe

lol. A lathe is just a backward horizontal milling machine!
i didnt use the word parallell as I dont think I can spell it
RE: Morons - Tony Betts - 30-05-2019
Hi hedd,
I understand what you are saying, and I've had parts in were this has been done.
But that's just not me.
If it was a special, then that's a different story.
Bob,
After all the cursing over what a previous moron had done, I didn't even check the bearing.
If I remember I'll check tomorrow.
Tony.

A real engineer makes flat things in a lathe and round things on a milling machine!

No, Charles, a real Engineer designs things that he gets a mechanic to make.

Isn't it 'all the l's '

Because the early (and sometimes later) stub axles are prone to cracking I would think turning the taper bearing seating to parallel would weaken it further (the stub is somewhat hollowed out as well)
RE: Morons - Hedd_Jones - 31-05-2019
Tony, all the later ones that Ive had that were cracked did so on the vertical face between the stub and the king pin bearing.
I take your point about thinning the stub, but there are other options. Make a tapered sleeve to push on, perhaps find a suitable bearing with a bigger ID. Or butter it up with weld, normalise and turn.
I could also get one of the minions here to do a FEA analysis. But then I'd have to do some material testing, and work out the loading. That's a ball ache.
