I can't comment on the front pulley (someone who has done this will chime in), but since you buy those set-ups to be specific to a drive train, I would guess they would send you exactly what you need. If it's the correct set-up for your bike and they didn't send you a spacer, you probably won't need one.

You'll need the outer bearing support for the trans. This isn't an alignment component - it's reduce wear and tear component.

 

You definitely want one of these...

1. It's a mainshaft support to help keep the tranny from leaking horribly from the seal. That shaft will flex without it. I put the motor to tranny plate there because I mounted a foot control on it, but it's not a deal breaker. Plenty of folks run without it.

2. Mount your belt and space the motor pulley so that the belt is straight. You will need a spacer behind the pulley so that the motor seal doesn't fail. The front pulley will hold that in place against the seal. I had to put an offset in my pulley to line up with the longer tranny shaft. You'll see when you mount you belt set up how much you have to move the front pulley out.

To clarify; my tranny mainshaft is longer than the one your using, but that doesn't mean you don't need a mainshaft support plate. You absolutely do need one. You may not have to run an offset for the front pulley though. Careful line up of your belt assy. will tell you what you need for a spacer behind the pulley though. That you will need. It just fits in the opening of the case when you slide it over the output shaft. They come in different sizes (lengths).

 

found a picture of what I'm talking about..

If you look closely you can see the sprocket shaft in between the offset and case. There is a spacer that fills that spot. I now have the belt straight here and need to find the appropriate spacer to fill the space behind my offset and the seal just inside the case. Hope that helps. I may even have a couple if you need one.

 

the first photo with the front pulley is with no spacers, you can see that it definitely needs to be moved.

i have a set of 8 motor sprocket spacers from Jims.

the forward facing photo of the pulley is with one of the spacers present, seen in the following photo without the pulley on.

hopefully pictures will help with ya'lls input.

 

first thing need to be done is obtain the transmission main shaft support and bolt up the clutch hub? then go from there with the belt alignment with the front and rear pulley?

 

Pay attention as you when you install that mount. The shaft should spin as free with it as it does without.

pulley and spacer wise, you will find what you need as you install. Test fit everything a couple times and really look it over. Shim as necessary.

 

Awesome thanks for all the input guys! Main shaft support is ordered.

 

Hey JAWS,
So I got the trans support shaft, but like you said it does create tension so the shaft doesn't spin as free as without, what do you suggest to let it spin freely?

 

Sounds like you bought a cheap one, or main shaft is bent.

 

It's the primo rivera one.. it's not the shaft because the whole transmission was just rebuilt... What brand do YOU recommend? It was like $50

 

I've used Primo. I do have one from Jireh sitting but haven't used it yet, so can't say about that one. You might contact the supplier or Primo about it.

I put one washer between the support shaft and the transmission, it NOW spins freely like it would without the support shaft... I think it's good now, but does someone have doubts on this method?

Not like I've done hundreds, put I never had to shim one. Did have one were bearing wasn't seated and had to clean up the hole for the bearing.

Nope. I shim them all. Ive only had one work right off. I believe its due to partially abuse of the old trans case and crappy newer parts. The old ones seem to take less.

that seems like a really long sprocket shaft. Is that a 70+ shaft for alternator?

i have a set of 8 motor sprocket spacers from Jims.
Those spacers replace the one that is already on your sprocket shaft, sticking out past your seal. They aren't really intended to be doubled up as spacers like you show. But that's not to say that you can't do that: but if you were to mimic the alternator, you'd be using a splined spacer I suppose.

the forward facing photo of the pulley is with one of the spacers present, seen in the following photo without the pulley on.

hopefully pictures will help with ya'lls input.

 

The transmission was rebuilt with the 70 and later shaft (12.5 in) , in a 66 case.

Where might one find these splined spacers?


I dig all the input!!
