How to change the primary wieghts

[jnj55024]

I have a 08 M8 with an SLP single pipe kit and will be riding in the Snowies around 11K ft

I have been reading all the clutching posts about changing to lighter weights than stock 73's. I think I have decided on the 70's with the stock yellow/wht spring.

Questions: Is there a good thread about how to change the weights with pictures? What do I need for tools? Do I need to pull the clutch or can it be done on the sled?

Help is appreciated.

Thanks for the quick reply Vern.

I'll try the threaded rod idea and see how it works.

I asked in that thread where to pry with a screwdriver but nobody gave a definitive answer. I think the Threaded rods sounds safer anyway.

i dont have any pic's for you, but i will describe the best i can.
all this should be done in order;
pull belt off
take a long screw driver or pry bar and slide it behind the spider and push towards the motor.this will open things up for you.
then while still holding it open w/ the bar, slide one of your new weights (or something else) right along side of one of your weights in the clutch and gently relieve the pry bar pressure until the new weight is able to support the load.
next pick a weight to remove ( other than the one you just put the new weight against)
use a torch to heat the small hex screw to loosen the lock tight.
DONT FORCE IT, if you strip the hex screw, your life will suddenly get harder.
after removing the screw, use a 7/16 socket and a wrench to remove the nut and o ring then carefully use a small punch to drive out the bolt holding the weight in.then swap it out w/ the new weight.
line up the notch in the bolt head, with the set screw hole in the new weight and drive the bolt thru the weight.
if you look carefully you can see the recess in the bolt thru the hole in the weight where the set screw goes in.
put some blue loctite on the set screw threads and install.
you my have to turn the bolt a little to get the set screw right on the money.
you will know if its right when the set screw is pretty much flush w/ the weight when tight.put the nut and o-ring on and snug up. doesn't go much more than finger tight.
then repete for the second weight.
when you get to the last one (use the pry bar again and pull out the new weight you slid in there to hold things open, and put one of your old weights
next to one of the weights you already replaced.
now you are free to swap out the last weight.
when its done, get out the pry bar and remove the weight holding things open.
put your belt on and your good to go........

god, i feel like i just wrote a book.it wouldnt be a bad idea to heat and remove all the set screws first, then you will now the rest will be no problem...hope this is what you needed.......mm

Pull the cover

Just pull the cover its faster and safer. Use a little heat and take your time.

Thanks for the write up Mtn Mike, I appreciate it. Mechanically it doesn't look too hard but I didn't know where to pry and was worried I would break something. I'll try it and maybe take some pictures along the way to help with this thread.

Yep, the bolts are long enough that you can remove the cover without having to worry about compressing the spring. Just take each bolt out a little at a time so that one bolt doesn't have all the pressure of the spring. It's easy to put back on too. Takes less than 5 minutes, and that is going slow.

I just changed mine last week. I just took the belt off, put my knee into it to compress it, stuck a screw driver in the spider to hold the tension and changed the weights like was described above. I would remove the screwdriver after each one, turn the clutch, recompress it and reinsert the screwdriver for each weight. Pretty easy this way. I started out using a c-clamp to compress it, but it was easier to just lean into it and then hold it open by sticking a screwdriver in there.
