I've got a replacement stock clutch basket with no gear. This old one has a broken finger but the gear is good. I would assume I need to grind the rivets off the old basket to remove the plate holding the gear on. Then apply the gear to the replacement clutch basket and weld the plate back on where the rivet studs come through. Is this correct? Thanks for any help.

I believe you grind the rivets and press the back plate/gear off. Then the new basket will use screws instead of rivets to hold the gear with a new backplate and cushions. I will be doing this soon as well...so anyone correct me if I am wrong.

It looks like he is just talking about the basket itself... :rolleyes: Once you unbolt everything and take the basket out. The stock basket it not serviceable (unless you fab it back together).

That is correct. You need to use red lock-tite on the screws. It's also suggest that you "ping" the end of the screws after they are tight so they can't back out. Make sure you have new cushions too to put in there.

Where exactly do you press to get this back plate off. The heads of the rivets have been ground off. I anyone can help that would be great. Just tryin' to get this done before this weekend.

OK if I am reading your post correctly you are replacing a stock clutch basket with another stock one. Regardless of what anyone tells you it can be done. They are servicable using the following:

1) Remove the clutch basket from the bike and make sure you take the bushing out of the center if it stayed in.

2) Grind the rivet swell off until you are flush with the backing plate.

3) Using a pin punch, not a center punch, punch the rivets down out of the backing plate.

4) Remove the backing plate, the clutch bumpers, and the glide plate from the old basket.

5) If your clutch bumpers are no longer in good shape, get yourself a new set from UPP or some such place. Yamaha does not sell them.

6) Take one of your old rivets to your local John Deer dealer. They are exactly the same size as the ones used to hold the scrapers on several models of older grain drills. Get more than just the 4 you think you need. If you do not have any other place to get them you also need to get 3 1/4 by 1 1/2 bolts and nuts.

7) Put the clutch back together using the 1/4 bolts to properly line up all the holes.

8) Put one rivet through the remaining hole and mark it to be cut off 3/8 of an inch above the backing plate. Cut all 4 rivets to the same length.

9) Using a torch heat one rivet up until it is red hot. This can take a little bit of time using a small propane torch.

10) Place the heated rivet through the clutch assy and set the head on a VERY solid object.

11) Using a hammer and a rivet rounding punch smash the rivet to within 1/4 of an inch of the bakcing plate.

12) Remove the bolts one at a time and replace each with a rivet.

 

Good luck, take your time and this procedure works well. I have fixed several clutches that had good baskets but bad bumpers exactly this way.
