Jack Rabbit scuffing
So I'm installing a JackRabbit Clutch in my 26. The directions say to scuff up the large metal disks with sandpaper so they are not smooth (I bought new large disks). My question is how much should I scuff them? Also How far from the top should I stack them? The directions say start with a large one then a Jack Rabbit one and alternate until you have a large steel one on top. Is there supposed to be a measurement from the top large disk to the top of where the bolts hold on the clutch plate?

Re: Jack Rabbit scuffing
Robert,
Used outer / metal plates need to be “deglazed” to give the best operation once reinstalled. Just give them a light
rub on both sides till the shiny glazing is gone. I rub mine across the plate both sides (but not in a circular motion)
It’s a similar process that you do on Brake Drums and Cylinder Bores to prevent grabbing
Generally, new plates are supplied ready to go and don’t need roughing up but sometimes I do give them a light rub.
Just the way I do it!

Re: Jack Rabbit scuffing
I'll give them a little rub. The new ones I have are real smooth and seem to have a coating on them. Thanks!!

Re: Jack Rabbit scuffing
Anyone have an answer for the other question?
"Also How far from the top should I stack them? The directions say start with a large one then a Jack Rabbit one and alternate until you have a large steel one on top. Is there supposed to be a measurement from the top large disk to the top of where the bolts hold on the clutch plate?"
