Howdy,

I threw the chain on my 6' tractor mounted snow blower
(because the master link cracked...)

In order to replace and adjust the chain, I have to
disassemble part of the blower.

There is a universal joint that is keyed, and its yoke slips
onto the drive shaft. Or, more accurately, it slipped on
when everything was new, and clean.

Getting it off has proven to be pretty tough. Using various
wedging techniques, I managed to get it off for all but
about 1/2" of its length, but I have not had any luck moving
it further than that.

And so, this question:

I know that by heating the yoke, I should be able to get
some expansion, and that should make removing it a bit
easier, but I have no idea how hot I want it to be to have
benefit, but without damaging the thing.

Also, whatever (approximate) temperature I was to shoot for,
how would I know when I was there?

I am clueless, and would appreciate any help on this hassle.

My torch, and I await...

Many thanks,
--
Kenneth
