While I wait for the dog teeth to be delivered, I thought I would change the seals (front and rear)



I built a tool for my wheel puller - have turned it to about 80 ft/lbs, kinda worried to crank it another turn,,,,,,

I am using penetrating oil on the shaft,,,,,,,,,what next?

Heat?

Incantations?

Ideas?

If you heat it up with a MAPP torch with it under that much pressure it will probably jump right off.

Part of the trick with MAPP or OxyAcetylene is that you can get lots of heat in the hub quicker than it can tranfer into the crankshaft. That expands the hub faster than the crank and loosens the taper fit.

Heating too slowly allows both parts to heat up at near the same rate and doesn't loosen the fit.

Way back when I really 1st getting into my 914 I bought a MAPP & Oxygen setup at K-Mart. Yup - Dinosaurs roamed the aisles. It was worth it's weight in gold for so many jobs. It was expensive to operate (Oxygen cylinders weren't cheap). But so worth it when I couldn't have even comprehended the cost of owning an oxy acetylene rig.

At a bare minimum run MAPP gas though your propane torch that alone is a decent upgrade in heat.
