getting the crank sprocket off!

Anyone have any tips for getting the crank sprocket off?
I've been trying with a three legged puller, but it won't budge!

Heat (propane or oxi/acetylene) is a wonderful tool to use with the three leg puller.

Be careful how hard you pull as the cast iron original pulley will crack chunks out of the rim very easily. I have a couple of examples in my broken parts bin to prove it.

Try using a bearing splitter behind the wheel rather than a 3 leg puller if you have access to one that will fit. Heat gently around the hub near the shaft as you pull and it should come off OK .... maybe

I buy steel replacement pulleys these days with a couple of tapped holes in the wheel, jack screws in the holes pull the wheel off easily without risking damge to the rim.

I think the word was sprocket not pulley,but at the risk of being labelled a luddite a blow with a well aimed hammer and chisel usually does the job

Hi John,
Yep, sprocket it is!
Hammer and drift was my next choice!

But wile we're talking pulleys, the pulley that came with my TC had some big chunks out of the rear flange, courtesy of a previous owner who didn't follow Rohan's advice. Luckily I had a replacement. My question: can these be repaired by building up with weld and grinding back to shape? Or is it too risky, ie bits of metal flying up through the bonnet etc....
