MIKE: Think! Motor pulley sheaves closest together ====== belt at outside of pulley(large diameter) ==== belt on control sheave pulley close to center(small diameter) ===== HIGH speed!:D

JPG40504 wrote:Question for you BOTH. How far apart are the outer edges of the two halves of the sheave when the 'stickey' condition starts. Is it less than 1/2"? They should NEVER have to operate in this position UNLESS you are using a badly worn out belt.

Also is it sticking on the key? Are the keyways damaged or not exactly lining up? Are the sheave fingers rubbing?

Ok long answer short, my situation is identical to mickyd's

I have my headstock taken apart cleaned it all up and I put the floating sheave back onto the spindle and it seems like the two sheaves kind of stick together or lock together a little bit. I can pull them apart but there is a little resistance initially. ....... Or is it just normal for the two sheaves to stick together a little because of they way they fit together? I hope that made sense.

Jeff - even with all that's been said above - I consider it NORMAL!!! I find my sheaves "stick" or "hangup" a little when closed together. I think they have, since the unit was new from the factory!

This issue NEVER happens when the motor belt is on!:) The sheaves just don't close enough to allow this.

My issue with this is so minor, I haven't given it much thought. I can see that Bill Mayo's description would/could be a real problem.

P.S. EDIT - use a feeler gauge to see if it actually is the touching/rubbing of the closed sheaves, or - Is it the keyway that's a little plugged and the key is s little stuck in pushing the gunk through the end unused part of the keyway(s)?

I knew that:o . (I edited my post). Thanks.

Ok good thanks for the information. I was hoping someone was going to say it was normal and it is just the sheaves sticking when they are close together. Once they aren't meshed it moves very smoothly, I was thinking that maybe the belt would hold them apart enough.

Thanks again
