Title: Polyclutch question
Post by: kurt-olsson on January 14, 2020, 11:03:11 am
I am using a Polyclutch for my throttles and have found a nice big sprocket that i will clamp onto the polyclutch.

Now my question is if i really need a shaft on the other end of the clutch?

I have seen Rob and Scotts setup and they only attach the clutch to the motor.

Anyone with experience (Scott and Rob read this :))

Did they work ok all the time and is there risk of damaging the clutch?

This will be my setup:

With those smaller Slip-Ease clutches, you would be better off with the other shaft. 
If you grab the sprocket you will feel that it has quite a bit of play in it.  Once you tension the cables a little, the sprocket will pull to one side slightly and be noisy and cause premature wear, especially as you are using plastic chain.

From what i have seen, I think Scott and Rob use the bigger Poly clutches with either a through shaft or internal bearing,

The clutches you have will work fine, I used the same ones in my previous TQ, but found i needed the second shaft.

Thanks Mick.

I will try to find a 3/16 shaft with bearing. Thanks again!

Mick,

How did you attach your sprockets to the polyclutch?

They are plate sprockets, and the center is bored out to a tiny bit smaller than the boss on the end of the clutch.  Then I applied Loctite 680 and pressed them on.  The end of the clutch comes off if you take off the circlip.
