DIY wheel bearing puller

First of all, I've used the punch and hammer method to remove bearings for years but, for whatever reason, the punch would just slip on this 2003 CRF450R wheel.

So, I bought a Motion Pro 25mm collet, just match the ID of the bearing, a 12" length of 1/2" BSW all thread and nut (12 threads per inch versus our 13-thanks loads Motion Pro-NOT!) from ebay UK and used a weight from a cheap dent puller.

Worked like a charm.

propane torch, heat up the hub evenly and the bearings will literally fall out when you turn the wheel over on those dirtbike rims.

So, it's a do-it-yourself slide hammer? cool.

I work in aerospace and once an aluminum gear housing with a bearing in a blind hole was brought to our shop to for bearing removal.

I placed the housing on a piece of wood on the milling machine with the bearing facing downward.

I then turned the shop lamp with a 100 watt bulb onto the top of the housing allowing the assembly to heat up.

Since aluminum expands roughly twice that of steel, the bearing simply dropped out of it's pocket once hot enough.

I plan to die young, as late as possible.
