opened can of worms

I recently purchased 2 go karts for my kids (or so the story goes) a Manco, and a yerf dog, both 2 seaters. The yerf dog belt shredded so I started removing the TC - after much swearing and frustration I got the movable sheeve of the drive pulley off the shaft of the motor, the stationary sheeve is stuck - I've tried heat, pullers, penetrating oils - no luck. I basically destroyed the driven pulley trying to remove it from the jack shaft (which after complete destruction I discovered was home made - see picture) When I was ordering parts I went ahead and got a new brake drum and band because they were not working at all - the key for the brake drum was the screw driver bit in the pic of the homemade shaft. I have tried to remove the rear axel to replace the drum but again am unable after trying all the tricks - heat, etc. Long story short this kart doen't want to be disassembled, my questions are...
1. Any thoughts on removing sheeve from motor shaft, I am afraid of putting too much heat to it and damaging seals
2. If I am unable to remove axel, or move gear on it to align the chain, what is the best spacers to use on the jack shaft to achieve the proper alignment - I was thinking washers
3. since the back plate of the driven unit isn't flat where is proper belt alignment - in line with outer edge, inner, or in the middle?

update - I purchased a better gear puller and got the back plate off the motor shaft, but it is now concave, so I guess I'm buying a new drive unit, the brake drum is out of round so I still need to remove the axel to replace. Still looking for ideas or help on that one... another question - what is the best way to remove and replace the front wheel bearings? I was thinking I can cut them out, and use a block of wood and mallet to install the new ones, butI'm hoping there is an easier way.

go to mfg supply. they have every part to your TC. great site. http://www.mfgsupply.com/gomini/gominiclutch/gominiclutchtorq/gominiclutchtorq30.html

it looks like you have a 30 series (flat back, angled front pully half) you need to allign the flat halves.

your driven back isnt flat? it may be a 20 series then. thats why your belt shredded

welcome to the forum!

The previous owner was crafty, but unskilled - between the homemade shaft, screw driver bit turned shaft key The belt they had on it worked but it wasn't even close to a proper belt (I am learning this all after the fact) I looked to me like the back plate on the 30 series driven has a slight angle to it although I could be mistaken - I won't be able to verify until tonight.
