So I might have completely and horribly destroyed my clutch. Maybe the #1 friction plate was completely destroyed. If that were to have happened, say trying to get out of a very irritating stretch of deep and soft sand I would be looking to get a new clutch (as well as pressure plate and possibly basket) for my 16. What's out there? What are the pros and cons of one over the other. Because of the amount of heat that may, in theory, of hit the immediate area I'd change the diaphragm spring, what's the merit to going with conventional clutch springs (Barrett, was it?). Last I saw mention of removing Yamahas circlip arrangement at the last friction plate, what is the merit there? Why was it there to begin with? To stop chatter?
Anyway for the morbidly curious:
I was pretty certain the clutch was hosed with I had a lot of rev but no go so I got it towed home. Today I pulled it apart for inspection. I've always said if you're going to break something do a damn good job at it. I think I did. These are the tabs from the #1 friction plate.
Frictions and steels, you can see visible wear. The circular arrangement of debris above is all I could find of the #1 friction plate at this point.
Next came the oil pipe below the pan. This was in the strainer at the reservoir.
And next comes the pan. Hey, there you are, friction ring! Lots of debris in the sump but very little debris in the oil pump pickup screen. At this point I'm going to put a couple cans of brake cleaner through it, swap the filter, clean the screens thoroughly, and put a new clutch in. Then that first oil/filter cycle will be changed out almost immediately with the next also coming short. With the pan so easy to pull (thanks for that design, Yamaha!) I'll pull the pan for at least that first change to check for debris.
So yeah. I need a clutch
