Hey, I've had this same probelem with mine. What happens is if you over torque that big nut on the jackshaft it actually PULLS the snap wring on the other side threw the bearing and eventually it snaps the snap ring off and the shaft is WAY out of alihnment. Only torque that nut just a tad snug, Dont wrench into it. Brrr its cold in the shop Had to get these pics for you. EDIT BTW I'm talking about the tiny snap ring against the bearing, Not the one under the big nut.

haha thanks but in talking about the driver the one on the motor though you were correct about the nut and it was part of the problem but the main problem is the one on the shaft its almost like it needs a half inch spacer or something remeber i did buy it used so i may not have all the parts but thanks for thhe help im working on pics but it mite be way to cold out

Ohh yes there is a spacer that goes onto the crankshaft before the back sheive. You must be missing this peice. The back sheive should not sit directly onto the crankshaft lip by the sidecover bearing or else it will be out of alihnment like no tommorrow. Either buy or make the spacer.

how do you recommend making a spacer like pilling washers in there or where can i go to get one order one and if i make one how do i know when the alignment is just right sorry about all of the questions i just want to do it right

I suppose you could use some small shoulder washers because most 3/4" ID washers have a OD of like 2". Or you can buy the bushing you need. I think you can buy it here.

Space it out on the crankshaft until the flat sides of the pullies are in line with each other. The belt you run has a beveled edge on it. The unbeveled side has to be lined up in order for it to work properly.

You should be able to put a straight edge on the inside (where the belt rides) of both pullies and have it sit flush.


I thought you needed a specially long crankshaft to run one of these. The other motors i've seen have no space left to get the washer on flat with the end of the PTO.

On my clone it'd help a bit if the crankshaft was about 1/2" longer but it still works fine.

thanks tyler but i couldnt find it on there did you see it and i missed it cause i really dont know what im looking for and heres a pic so you can be sure thats whats wrong you can only kind of tell its out of line

I can see from your pictures your missing that spacer. Call up Comet and tell them what you have.

i found there website but they list 3 diffrent spacers for the tav2 a 1in crankshaft spacer $16.95 and a 3/4in crankshaft spacer $10.55 also a spacer for mounting brackset $4.95 and they dont have pictures i was woundering if you knew which one i need
