I just replaced some bearings and my belt but I'm pretty sure the clutch is out of alignment now, the belt dosent seem to engage properly. I've never worked with CVT clutches before so this is all black magic to me and info on YouTube is spotty at best and can't find help in either manual I have. Is anybody on the north side of Edmonton that could pop in and show me what's going on? I like to do all my own wrenching so taking it in dosent help me learn, only lighten my wallet. My trailer was recently stolen so I can't get the machine around at the moment. I have cold beer in the fridge and I would happily compensate someone for their time and teachings. I'm not far from the Y in Castledowns (153'rd ave & Castledowns road)

If anyone can help please PM me, any help would be much appreciated :beer:

Took ya 20 years to learn how to align a clutch?

Yep, 20 years to learn how to align a clutch. And it also took me 20 years to learn how to tell you that your primary needs rebuilding and your secondary needs new buttons, new spring and sec'dy needs to be cleaned. But whatever. After aligning the clutch 3 ways, setting belt to sheave clearance, doing all the small things that others don't, just a full day of aligning and rebuilding clutches. No biggie.
Buy olav aaens clutch tuning handbook.

Looks like the belt needs to drop into the secondary. Loosen the 3 bolts on the outside of the secondary and turn the ring behind to adjust the belt tension. Is the belt dragging at an idle a causing the sled to creep forward? 2 hours is too far for me to drive for a beer when I have one on the go already.

You replaced bearings?, jackshaft bearings?

Did you have the clutches apart or just had them off?

When you say the belt doesn’t seem to engage properly, what are you exactly meaning?

The alignment is done on the secondary of that sled, with shims on the jackshaft on the back side. There may be shims behind the washer on the mounting bolt as well.

Dont take any offense to the dog.... he likes to ruffle feathers.

there is a lot to take in as far as clutching and proper clutching setup/alignment goes, but I know that there will a helpfull person who can recite all of the older edge clutching specs without even needing to refer to a manual. Have patience and someone of our community will swoop in and save the day.

Thanks for all the replies, very much appreciated.

Yes I did the jackshafet bearings, I only have a few hundred K's on the machine and decided to fix the speedo that didn't work, after peeling back that onion the jackshaft bearing was so shot it was wearing through the bearing retainer plates (excuse the rookie terminology) that hold the bearing to the tunnel on the clutch side where the speedo cable plugs in. So I did the 4 main bearings but now I'm having trouble with belt tension. I'm pretty confident the belt is aligned right in the primary but the belt sits loose and I have to give it quite a bit of gas to get the clutch to engage, I'm told it should take just a small hit of gas?

I thought it was an alignment issue givin the new bearings would bring the secondary back towards the front and go out of alignment (I am assuming the previous clutch setup was ok as it ran like a top till I pulled it all apart) but it appears to be ok, just a loose belt. Is this when I have to adjust the motor mounts to pull the engine (and primary) forward to get the belt to tighten? The 3 bolts as someone mentioned only spreads the sheaves

Kanedog, correct those buttons were worn RIGHT out and it was just starting to eat into the aluminum, I cleaned the hell out of the secondary and had a local shop reassemble it for me just so I knew it would be set right. Was planning to put a clutch kit on this summer, I'm not going to wreck anything by running it like it is am I? I'm not looking to do any damage, the previous owner must of been a "just gas it and go" kinda guy. I was working at Albian when a friend of a friend was selling it in Ft Mac so I had a local shop do an inspection since I had no way of looking at it, nor would I know what to look for, amazing they missed the jackshaft wearing almost through the tunnel

Here is a pic of the machine running at idle, the belt rides smooth with no chatter and appears to be centred. Thanks again for all the replies, very much appreciated

I have to rev the throttle roughly 1/2 before it will engage. It used to be just the smallest blip would engage it

If you didn't take the primary apart your issues is the spring or weights in the primary clutch sticking. Take the belt back off, then blow all the belt dust and debris out of the primary with compressed air. After that wash it down with hot soapy water and rinse. Blow it out again. Wash the belt with hot soapy water also and rinse and dry it. Put the belt back on and running it through full rpm on a track stand and watch the clutches shift in and out with varying throttle. If the engagement rpm is still too high you will need to take the cover off the primary and check for a broken spring, binding in the spider or cracks and weights that are stuck. While it is apart make note of the size of the cam weights and the colour of the spring.

There is also 1000ft difference in elevation between Edmonton and Fort Mac. You can probably run a slightly lighter set of clutch weights.

Hey Was the primary rebuilt.? Your issue arrived after working on the jackshaft right?
Reving the throttle 1/2 to me is holding the throttle in its half throttle position. Is that what you mean?
If thats the case on a unloaded clutch, it would rev a stupid amount To engage it. Im trying to figure out what your seeing, through your explanation.

I have to hit the throttle to about half to get the primary to engage but can back off and it stays engaged, just have to really hit it to get it to grab but I already know the belt is too loose so I'm guessing that could be the prob?

I did't touch the primary no, just the secondary. You already answered my next question about altitude difference and spring rates. Im going to put a clutch kit on it this summer so for now I'd just like to get it going so I can hit some of this snow we just got & save as much work till this summer but it has to be "right" before I take it out again, I am boarderline neurotic about maintenance and things working properly (my last s10 blazer had 400K on it and my friend drove it another 100K before he rolled it & my current ZR2 has 240K and it still runs like new, I'm ALL about the maintenance)

I'm also going to check the jets, it's pretty tough starting in the cold and givin what I know now about the previous owner being a "just gas it and go" kinda guy with little to no maintenance I'm assuming the carbs are all gunked up too and I cleaned up the exhaust valves, they weren't to bad. Thankfully he only owned the sled for 2 years so hopefully the previous owner took better care of his machine. The belt I soaked and scrubbed before I put it on, I did forget to scuff the primary but spent about 5 hrs polishing the secondary. So I believe I'm at scuffing the primary and bringing the motor forward to tighten the belt, sound about right or am I missing something?

As allways thanks for all the input, you guys are a HUGE help. Both manuals I have are kinda hit or miss with info

If someone get offended buy what you said they definitely need thicker skin, it's on them & not you.

ALOT of people need thicker skin, it's gross how everyone is just looking for a reason to be offended these days.

That's the reason I don't do Facebook or any kind of social media, it all leads to drama, no thanks

tightness of the belt is adjusted by secondary clutch
off set is 5/8"
belt defection is 1.5" to 2"

Check belt numbers to make sure it’s the right one for the sled. If that’s good, check belt deflection. This can be adjusted at the secondary by loosening the three bolts on the side and closing the secondary so the belt rides a bit higher.
