An air chissel with the hammer bit should get it too.

 

Got an air chisel , no hammer tip. Not much room to get at it either.

 

Most of the shops I've worked in have those heaters, Lou. Not a big fan. The heat is too localized. They heat things instead of area.

 

I can’t figure what was keeping the yoke from just spinning on the gearbox input shaft?

 

Two thick pieces of steel plate behind the yoke and resting on the case then a pair of bug chisels and wedge the yoke. Once tension is achieved then heat the yoke. It should pop off. Old mad once told me heat and cool 3 times will break any bond.

 

I was just thinking the same thing.....

 

Broken key is wedged in the yoke. Might not be pretty when it comes apart. The key is softer than the shaft and yoke.

 

 

If you can lock up the gear box you could put a bar through the u joint and bar it back to the original position. It should come off easier.

 

The yoke moves on the shaft about an eight inch. So it’s not frozen. The key way in the yoke is directly under the set screw hole. You can see the key way in the shaft ?
