Whats the best way to get these little f*&ker out for a crank. Apart from the old wifes tale of filling with grease etc.
If you are able to get in with a mig welder, run a continuous bead of weld round the inside of the bearing. This shrinks it and it comes out
relatively easily.
This works for mashed front wheel bearings stuck in hub carriers.
The old wives tale works for me, failing that a small slide hammer. To use the grease method use a good fitting piece of bar and hit sharply with hammer, too loose a bar will not work
Fill it with grease
Packed mine with grease and used a cut off input shaft (perfect fit) - Still would'nt budge.
In the end I took a Dremel to it
If I thought it might of been used more than once I would of bought a puller.....
Btw : Old spigot bearing's used to be bronze so you got an excellent seal for the grease trick - the roller bearings they use now don't give
a decent seal.

Can someone explain to me how its done with grease.
never done this before BUT does anyone think a rawl bolt would work as a puller in this situation. I know it would put force on the sides of the bush
making it effectively tighter but i've an inkling that it might work.
What do the rest of you think ( no smart arse replies please as i'm a sensitive soul )
If the body of the raw aw bolt is ground down so it hooks in behind the bearing yes.

I've had mixed results with the grease system, one pass (but I got covered in grease...) and one fail - where I had to make a special tool in the end; this was a threaded insert, sawn up. Poke it through the bearing & screw the bolt in so it locks behind - then keep screwing (!) & the bolt pushes the spigot out. (hope that makes sense)
Cheers everyone
I've used the grease method, which works fine if old spigot ok.
However, one was completely knackered, so I managed to use a hack saw (carefully) and cut it out.
