#35 sprocket for my1020 500 watt motor.

[Vartz04]

What's the best way to get a #35 sprocket on one of these motors. I already gave a 60t sprocket so I'd prefer to just change out the one on the motor.

That would depend on how it's fastened and indexed to the motor. Pictures and measurements tend to be helpful.

you'd need a B-Type sprocket (thick colalr with set screws)
but the problem you'll have is that you need a #35 with only 8mm bore..

smallest 'common' I know is 3/8" bore (1/16" too big roughly)

So... if you do not want to spend a lot of money on shipping, I cannot provide you with any source.

In germany we have maedler

one of the smaller ones will do after slight modifications I guess (predrilled bore to 8mm...)
3/8" pitch.. the sprocket itself is actually too wide to take a #35 chain though..
you'd still have to turn it down a bit.

So yeah...
get a rear sprocket instead, that'll be easier to find

Well That's unfortunate as the rear sprocket js going to be hard to find with a standard 4 bolt pattern and in a #25 size. I never thought this would be an issue when I purchased the motor.

I went through this on my build using a 48V my1020 motor.
I bored the sprocket out with a stepper bit and secured with 2 set screws and the nut that came on the motor shaft.
However, I have since lost the shaft nut and having a hard time finding a LH metric replacement. My last ditch solution is to weld it to the shaft.

I'm considering welding the two sprockets together. Might get to try it tonight/this weekend so we will see

bit the bullet and welded the sprocket to the shaft.

Nice. I ended up welding my two sprockets together. Works fine pushing my butt in the cart without breaking.

Nice 80/20!!!!
I used that temporarily on my first cart

temp turned permanent it also provide a means to adjust the chain tension.
