Removed my QSC and disassembled the one way, cleaned it and re lubed with isoflex put her back together. I ran great for 10 minutes but now she is hard to shift and it crawls in gear, a bit of squealing too. The interior of the housing is spotless, some thing hanging up???:th_smiliepullhair:Cleaned the STM secondary while I was there as well thoughts?

Are you sure the secondary was assembled properly? If you ran the bolt in to open the sheaves and it opened up OK then it should be good. The only other culprit I can think of is the one ways. Did they spin freely by hand? How much grease did you use? It takes a small amount and is easy to over grease them.

I guess my question is can you re assemble the one way incorrectly??? I removed the needle bearings and the small leaf springs for cleaning....can you put those in wrong? The secondary was not dis assembled, just a rag and some brake clean so we are looking at the one way I fear.

I asked about the assembly of the secondary. You mentioned you cleaned it, but if you didn't take it apart then its gotta be something in the primary, and very likely the one way

Ripped it all apart last night, no issues with anything other than I replaced the 2 washers on either side of the one way, checked the one way it is working perfectly ( only rolls one direction) did not over grease, primary spring is excellent, replaced the sliders on the spider, polished, inspected, did not overgrease, double checked the torque on the spider to 200lbs, 60 lbs on the primary bolt, unit is sliding in and out like a dream.......now about that STM secondary... got to thinking if the red fiber spacers started going would that pinch on the belt too much and allow some creep??? All was good last night save for the creep and the belt squeal when I am sitting in gear, anyone?

With a clutch with a one way bearing you can essentially take out all those red fiber spacers in the secondary. You want as tight of a belt deflection as you can get. The spacers are only to adjust belt deflection for a primary without a one way bearing.

B, not to create stress but I was told to ensure I add the spacers as for sure it will creep with out the spacers in place...not arguing just what I was told to do. Your statement is correct though the spacers do control belt deflection/pinch.

It SHOULDNT creep without the spacers. If it does, you still have a sticky one way. That's the whole point of a one way bearing in the primary. That's why we don't have to check belt deflection. Aside from knowing this by researching it and talking to clutch tuners, I also did it first hand and have zero creep and no more than normal can am shifting issues with the same clutches as you.

Pull the clutch cover and start the machine and watch what happens to the primary as it idles. Do the sheaves begin to close at idle? Mine started to do that when the spring broke in a bit. I had to add the spacer in the primary in order to bring the engagement up a bit. Work perfect with the spacer. I bet that why you're creeping and have a squeal. It's your clutches trying to engage at idle.

I do have the spacer as well, I wonder if the spring is softening.... its the blue striped silver spring from QSC. I agree it seems like at idle the primary is rubbing on the belt. I hate to phone QSC for another primary spring, he has not been responding to emails or answering his phone and it will take weeks to get one up here in Canada, any other springs that might work? Or add another spacer?

Adam doesn't really speak much direct anymore. He's so busy lately just feeding his vendors. Best bet is to get a hold of a QSC dealer, like rvsperformance. I'm actually surprised he hasn't already chimed in. He's on here all the time. I bet your spring is too soft. Not sure what color mine is, but your sheaves shouldn't move at all at idle. Shouldn't even move until about 1800 rpms.

Correct, my usual engagement is around 2000 rpms. I will see what I can do with the spring. It just strikes me weird that after I clean the unit and replace the one way washers and lube the belt starts rubbing/squealing.

Just to confirm what BL said, I also run no shims in my STM secondary....at idle the belt rides on the one-way....not like a sled where you need the deflection set or it will creep.

Somehow in your R&R of the one-way it has decided to hate you. LOL.

I should have never taken it apart LOL I use the EB 38 helix but this should have nothing to do with the shims......They are all out of stock in Edmonton and surrounding areas or I would have just replaced the damn thing, $61.99 but nobody has one...
