Spoke issue
Can anyone help me . I just got into this forum and thnk god for it. I bought two engines on a whim. Trying to install the sprocket. It has 9 hole and as I have found out is set up for a wheel w/ 36 spokes. My bike has 32 spokes. So far I have figured out I can get 8 screws through but am having one **** of a time with getting the three back brackets to line up and not overlap. Amazingly the sprocket does seem to be alligned pretty well. The only way I can tell is by spinning the wheel and watching the bottom of the sprocket. If there is a trick to making sure there are no allignment issues before tighening down screws I would love to know it . Thanks for the Help..

Re: Spoke issue
Somebody heres got the answer? Haven't run into this yet.Call the vender you got the motor from is your bolts to this 6mm or 8mm. Betting the 6mm would cure it. These 6mm and 8mm have diff patterns 6 mm clusters the pattern to a smaller bolt up closer to the hub.

Re: Spoke issue
Will a 5 hole sproket work better? I have one you can have if it will.
As for the alignment thing, tighten slowly like lug nuts- cross pattern and just keep eyeballing it as you go.

Re: Spoke issue
For the short term, I switched over to a different rear wheel with 36 spokes. New issue with this rim is the portion of the hub that the gear lays on doesn't come out as far from the wheel. If I install the outside rubber donut it pushes the gear out to far and it doesn't have a tight fit. Is it ok to only use the inside donut if the gear doesn't ride up against the spokes? PS you guys are a god send and I'm really starting to like the challenges this hobby brings.

Re: Spoke issue
Coaster brake or other?
Sometimes with a coaste rbrake wheel, you have to grind off the dust cover flange to clear the sprocket.

Re: Spoke issue
apologize for how green I am on the bike vocabulary. I'll get better. It's a 13 speed canondale with hand brakes hub ( I think Shimanno) is slightly concave. So as long as it can sit back far enough I have a tight fit. The thickness of the donut pushes it to far out causing it not to be flush.

Re: Spoke issue
I don't think it would be a good idea to mount the sprocket without the second rubber. The whole works (sprocket, rubber,spokes, rubber, metal plate) acts as a clamp and a sprocket mount.
Anybody else?

Re: Spoke issue
If it's sticking out as you say, is it hitting the chainstay (frame rail)?
As long as you can keep the chain and both sprockets lined up, you can shim the frame with a washer or two.
Am I headed in the right direction?
