92 Par Car Primary Drive removal

[lowflybye]

Can someone please tell me how to remove this thing? I need to change the crank seal. We tried placing a stainless steel rod down the shaft and fabricated a nut that screws on to the outside threads on the shaft with a bolt that pushes on the rod. We even heated the base, but to no avail. We put enough pressure on it to bend the steel rod but the Primary Drive did not budge.

Nobody has an idea?

I have since tried a new method of placing two grade 8 washers below a grade 8 nut that is threaded onto the top of the shaft. I placed a grade 8 bolt down the shaft and an using a gear puller with the setup. The gear puller pulls against the washers attached to the Primary Drive and pushes the bolt down against the crank shaft. I squirted Kroil down the shaft and heated the base with a propane torch while placing enough pressure on the gear puller that the (2) grade 8 washers are bending and the PD has not budged. I am running out of ideas here...I left the setup under pressure in hopes that it will work its way lose, but not holding my breath.

Do I need to get a hotter torch and heat it till it begins glowing?

Columbia uses a tool kit to remove the part. I think it is a pin that fits inside the shaft then a bolt that fits the threads inside the clutch shaft then tighten the bolt with pressure on the pin inside then strike the head of the bolt with a hammer and it should come off,
Hopefully!

The inside of the shaft is not threaded so that tool is useless. I have now heated it to glowing red and it did not budge. The only other option that I know to do it try to cut it off without damaging the crankshaft and order a new primary drive clutch...

I didn't know exactly which clutch you had so I tried one. Sorry I wasn't much help! If there is much crank end play you might pull the end play up and block under the starter pulley then punch down inside the shaft with a hammer and a long punch. don't damage the starter pulley when blocking it. Or try to have someone hold the end play up then use the punch and hammer. Good luck!

Got it off...had to cut it off with an angle grinder. The culprit was a softer metal bolt that had been broken off down in the shaft by a previous owner trying to pull the clutch off. The more pressure I put on it the more it mushroomed and when I added all the heat it basically welded itself to the clutch. So, now I have a new clutch ordered which stings a bit, but at least now I can get the cart back up and running.
