Pilot bearing bullshitery

[brian]

Wtf is this crap?
Bread trick didn't work.
Harbour Freight slide hammer puller didn't work.
The old school corded milwaukee diegrinder got it though.
A tiny bearing in a bushing, in a bushing in the crank.
Fortunately it appears that the correct bearing will still fit.

Grinder and BFH works every time

I actually did the bread trick last month and it worked..I was a bit surprised..brioche, too..fancy.

I was skeptical, but it worked....

My guess is that there was enough bread squeezing through the inner and outer race of the bearing prevented it from working.

I believe the bearing was lock tighted into the first bushing, which was then lock tighted into the second bushing which was then locked tighted in the crank.

Some people's kids...sheesh

Once you're down to the outer race run a quick bead with a stick welder round the inside, make sure earth clamp is on the flywheel. Deals to loctite and shrinks the race.
Bread has always worked for me.

Hadn't seen this before.

Good luck with a ball bearing

True. Getting it to stop spinning is easy. Weld will make that stop quickly.

Getting a tap to cut that inner race would be basically impossible.

Does anyone know of a source for “unusual” (custom) Oilite bushings?

I need a 12mm ID, with a 1” OD to adapt a Toyota W58 5 speed to a Triumph TR6 motor….

I figured people here have a lot of experience….

Thanks -

If you can't find the size you need, it's possible to machine them. I needed to modify a couple for an emergency repair once. I cut them on my lathe. Read up on machining Oilite material. It can be machined if necessary. The wrong way can cause problems though.

Would it be possible to press a 12mm ID Oilite bushing into an adapter piece machined to 1" OD?

Probably.

I thought about your solution, but haven’t found any bushings that were very thick, and was worried about heat cooking the oil out of a very thin piece.

I’ve got a 1” dia. bar on its way. Most likely I’ll machine my own, but was hoping to find a “drop-in” solution….

I’m pretty certain that when the bushings are made, they are compressed to the proper size directly….

Maybe I’m overthinking thinking this…
