clutch problem maybe?

When I retorque my carrier nut, I get on the bike and put it in gear and put the front wheel against the block wall in my garage. Since it's reverse thread when you torque it the bike wants to move forward, I believe it's 80 lbs, and it's very easy to do if you have a long wrench. I also put red locktite on the mainshaft splines, I heard this will help to take slop outa the fit between the basket and the splines. Never had a problem getting it off again and I've done this maybe 20 times between the handful of bikes I maintain. If it does get sticky just warm it up with a torch, just be careful not to get it too hot so you don't damage the mainshaft seal.
i think you are right as it says in rays scanned pages that it is 80lbfts . i was getting scared when i was putting all that torque on the shaft so i stopped and had to do more searches:bang: or are you guys putting 150lbft on it :confused:

recommended procedure:

1) remove clutch hub nut and clean both the nut and the threads fully of all (if any) loctite
2) torque assembly to 150 lbft to draw everything together
3) remove nut and apply red loctite
4) re-torque assembly to 120-130 lbft.

should be good to adjust and ride with no problems.

i think the 80 ft lbs was later updated to what is said in wood's post. I thought (from memory) it was 150, then remove and loctite, and do up to 100 but I suspect wood is right.

Exactly what it is

If I were you, I'd figure a way to safety wire that nut so you never have to worry about it again. Don't pull the circlip, it should be holding in the outer bearing on the center hub.

I tried the 150, then remove and loctite and torque to 100 and it came loose again.
Second time I had to do it I took it to 150 and removed it, loctite and torqued back to 150. Haven't had it come loose again.

This just happened to me exactly Sunday. It is a stretched clutch cable. I'm currently trying to reinstall the new cable. Iggy

I too have the symptoms of the loose clutch hub nut.
Took everything apart and the nut was loose. I now have everything cleaned and ready to go back together,

I seem to have an issue when I try to tighten the clutch hub nut. the inner hub just spins. Tried holding down the rear brake, no good.

I have attached a picture of how the assembly looks.

How can I keep it all from moving so I can torque it down???:bang:

Do you have the bike on its tires or up on a jack? Put it in 2nd or 3rd and with the rear tire on the ground, hold the rear brake down and torque it. If its up on a jack put a rag in between sprocket and chain.

Information

Forgive me if this sounds stupid but when everyone is talking about tightening the clutch hub nut if I have a right side drive would that nut be on the right hand side? Can someone give me some pictures?

not a stupid question at all. I just went throught the same thing. Some of the terminology on the forum could get a bit confusing.
I just went through this on my 2008 pitbull which is right hand drive.

The "clutch hub nut" is inside the primary cover behind the pressure plate. It is a 30mm reverse threaded nut that holds the clutch assembly together and is seated at the end of the push rod. This nut should not wander in and out. It should be stationary and torqued super tight with loctite.

The "clutch adjustment nut" is located on the right side of the bike. There is an 11/16" locknut on top of the 7/32" allen nut. The 7/32" nut allows proper adjustment of the push rod which runs axially throught the the transmission and clutch assembly.

If the "clutch hub nut" located inside the primary is stationary then you can adjust the clutch adjustment nut as described here

I suspect if it is unthreading then constant adjustment of the clutch will eventually be needed. Mine was loose to where i could take it off by hand. This is common, and a lot of the guys on here have been there/done that.
I'd offer up pictures as i took a shitload when i did this. I just don't know how to post them in the forum.

I could not turn it by hand but I have to get a big enough socket to see if it is still loose. If I take the hub nut off will I be able to remove the clutch basket without anything falling apart so I can inspect it?

drain the the primary oil, remove inspection plate and finally primary bolts.

I've removed them and placed them in a cardboard jig so i know how they go back in. probably not necessary as they are all the same size. the picture does show the tightening sequence which you'll need during final assembly.

with the primary cover off inspect the gears and locate the pressure plate

remove the four bolts holding the pressure plate on.

pull the pressure plate off.

when i did this the clutch plates came along for the ride. just be sure they are installed in the same manner

now you have access to the hub nut. remember it is reverse thread. you need a torque wrench and a 30 mm socket. tighten it to about 150 pounds before backing off the nut

once removed, clean up the threads on the shaft and inside the nut itself. you can see the tip of the push rod sticking out the end.

apply the red locktite on the shaft threads and inside the nut and reverse the sequence. tighten the dreaded "hub nut to 100-120 pounds

hope this helps

forgot one thing....well two things

once this is done, and depending on how loose it was to begin with, everything between the "hub nut" and "clutch adjustment nut" will be pulled together.

In my case the gears would not engage. even with the clutch lever all the way out and the bike in gear. this is where you have to adjust the "clutch adjustment nut" on the right side of the bike. see earlier post.

Oh, and don't forget to put a quart of primary oil in. and make sure your drain plug is in. cheers

I just want to say thank you to Bill and everyone else for the great information. I have a 2008 Pitbull and it felt like the clutch was slipping at higher RPM’s because you could no longer feel the bike pulling, or maybe I should say it was no longer propelling forward-faster.:confused:

So I brought the bike into the shop……followed the directions that everyone provided...to check the lock nut. Sure enough it was a little loose. Then after putting it all back together…..the bike is now running great again!!:D

You guys are the best!! :2thumbs:

trans fluid

My clutch carrier is split in two. When I pulled the carrier, lots of trans fluid came out of the shaft. The bike is on the ground on its stand when I pulled the carrier. visual of the seal looks good. Should I worry and wait and order the seal or put the new bandit clutch in. Thanks in advance.
