Hi all...the inner sheeve doesn't balance up with the rest of the primary clutch does it,the inner sheeve is balanced by itself right?

The inner is balanced. You just have to put the spider and outer back on the same

correct.....the are balanced independently. Just make sure when you reassemble the outer that you line up the marks on the outer with the governor cup she reassembling

What are the symptoms if during re-assembly the marks are not aligned correctly?
i think that i might not have aligned the marks when i removed the assembly to service the one way bearing.

thanks

youll get vibration. best to double check.

I built a tool and started balancing my clutches on my brp sleds and it made a big improvement . They say they are done at the factory , but I found that they don't do a very good job . I found that by getting the primary spot on they work smoother and parts don't wear near as fast . On my sleds that I did the idle went up 250 rpm by having the primary's balanced .

I think I will do my turbo primary and float the secondary

Are you static balancing them? Would you mind showing us a picture of your balancing fixture

 

[Troy]

Yes static balance

 

[Aircraftman]

cool- we use a static small wheel balancer, is that similar to what you have?

 

[Troy]

No , I put a threaded shaft through the centre of the clutch . It then is hanging by the horizontal shaft which is resting on bearings . Then it will always spin on the bearings and the heavy side on the clutch goes to the bottom .

The home built tool has a nice heavy plate on the bottom and two arms that come up about a foot . Each arm has two bearings on it . So the balancing shaft sits on these 4 bearing while your working on the clutch . It's about as simple as it gets . I removed the seals on the bearings and lube them with very light oil . A half of a paper clip on a clutch will make it move on the tool . Some clutches are terrible . I have found that I can true many by re-positioning the clutch components and the make new timing marks . I did come across two clutches that were 100% perfect .

10-4- thats the same type of setup. then you drill to balance.

 

[Troy]

Yes if you can't true it by retiming
