Torque converter/clutch alignment

[c310pilot]

My used trailmaster was retrofitted with a Predator engine by a previous owner. The clutch and the driven pully are out of alignment. This is causing the belt to slowly deteriorate. Is there suppose to be a spacer between the engine and clutch? I machined a half inch spacer and placed it on the drive shaft between the motor and clutch and this seems to align the pully but now the torque converter/ clutch bolt is to short. What am I missing here?
Thanks.

A longer bolt.

I just picked up a bolt today. The hardware store didn't have the same length that came with the kit. So I got a bolt about 1/2" longer. I'm wondering if it will be too long. Not sure how deep the threads in the crank are.

Anyway, it is 5/16-24 (Fine Thread). The TC kits come with metric bolts that don't fit Predators which use SAE threads on side cover and crank.

Yes there is supposed to be a spacer.
Here it is...

Went and got a longer screw and the spacer set up seems to work well. My next problem is that the idler bushing slides under the clutch and catches keeping the clutch going back to full idle. Checked for burs and such. What now? Thoughts?

its probably your weight pack wearing down, weight pack studs bent or worn, or most likely, just some crud built up in the hub.

Nothing a good wire brushing of the hubs and some dry moly lube cant fix. Even before i read your post, i noticed the drive unit moveable sheave was not fully disengaged in your picture.

I have completely disassembled the clutch and soaked in parts cleaner. Wire brushed and filed any burs. The weight studs are straight and the weights slide freely with out the springs on. I reassembled the clutch with a dry moly lube and used Milcom 25 on the hub. The bushing slides underneath the clutch Drive plate at RPM. Should I have a wider bushing?

the issue is, the predator has a rather short shaft which isn't exactly nice for a TC setup.
it works though with a longer bolt.

IMHO you best machine another spacer (basically a short length of 3/4" keyed shaft with a throughhole) to add some support for the driver (the key should span both the shaft and the spacer )
