My bike is stuck somewhere and the only way to get it out is to replace the clutch plates and ride it out.
Unbelievable but true. Pushing or towing it out is not an option. I'll tell ya where after I get it out.

What tools will I need, I only have a manual for a 426 and I think the clutchs are slightly different. The 426 manual shows 6 springs and the parts guy said I only need 5? I'm hoping I can just replace the plates and springs without having to pull the whole housing.

The parts will be here tomorrow I need advice fast. Anyone that has rebuild one please let me know what tools I'll need and what the procedure is.

Thanks

p.s. it was a fun day until my clutch burned up and I had to hoof it up that hill.

No this is not a joke

I was planning on capping the vent and laying the bike on it's side so I wounldn't have to drain the oil

When you say retaining nut? do I even have to pop off the clip?, from this blow up it looks like I can just remove the nuts that hold in the springs and the presure plate and all the plates will all come out
Do I need to remove anything else?
is it the same as this only with 5 springs

I went in today. You were right on the money my freind
an 8mm, 10mm extention and a 1/4 drive rachet is all I needed.

Bike is home save and sound now.

p.s. if any on wants to know where it was? it was at the bottom of "Snowy Trail" in Los Padres NF, just west of Hungrey Valley. The only double black diamond trail in the forest. It wasn't that bad of a hike in(a little over a mile) until I heard the Mountain lion grawling at me :thumbsup:, I guess he didn't like me walkin up his hill, I found a differt route around "his hill". True story, ever try working on your bike while you looking over your shoulder the whole time??, I need a beer :devil:
