Yerf Dog 3203 with a 212 Predator - Need Advice

[JaySki74]

my son and I picked up a 2006? Yerf Dog 3203 that had a 212 Predator added at some point. The TC was pulled and it looks like he tried to add a CC instead.
I have all the parts (I think) of the TC and have been working to reinstall.

Problems I am seeing... The jackshaft sprocket is SLOPPY. I can't find ANY info on jackshafts to determine is it missing a bushing or a bearing(s).
How does it come apart? Or is it just a replaceable part? Where do I find them for purchase?

The predator with the top clutch on, does not line up with the clutch on the jackshaft.

I've been searching around here about 30 minutes with no luck.
