Ugh, Need help with a couple things By Jeff (Read 1,813 times)

Update: Fixed my air wrench and it wouldn't budge my nuts either. Got the torch out and heating the variator nut for 15 seconds at a time, then hitting it with the electric wrench, it took about a minute and a half of heat and the nut finally came off. The nut on the clutch never came off. I heated it for probably ten minutes or more, it was extremely hot and smoking, and still wouldn't budge with either wrench.

The variator nut was the most important so I'm glad that one came off. I didn't really need to remove the clutch, just wanted to inspect it and be able to better clean out the inside of the variator case but I worked around that. The only way that clutch nut is coming off is with a much bigger impact tool plus heat and I'm not going to bother with it at this point. I have a nut breaker tool and a dremel so I thought about cutting it off but I'd have to go to a yamaha dealer for replacement nuts.

So here's a picture of the inside of the variator. Unreal how much grease is in there. I could spoon it out. It was so much that it was actually leaking out of the variator outer cover which had a poor gasket. I thought the leak was due to an engine or tranny seal leak into the variator housing but it was just variator grease.

After cleaning and using lithium grease for the rollers. Even this much grease is probably overkill but not too much. The rollers weighed 14g and had very slight flat spots developing after 5000 miles. All the grease the factory put in there didn't stop the rollers from getting flat spots. I thought the factory might have done it to reduce noise but I think they're just clueless.

Jeff, Now is the best time for you to change from rollers to sliders. After the most difficult time you had to remove the variator why put the rollers back in it? I have the same variator and if I had 5000 miles on those rollers they would be replaced. Have you checked the belt for wear? BTW sliders need no lubication at all.

I thought about the sliders, but I first want to see what if any difference I feel with the stock rollers and the proper grease. The flat spots are very minor at this point, and now that I've been in there, taking it apart again to install sliders will be trivial. The belt is a 871 x 23 and it looks like new but I didn't measure it. I need to get one of those cheap digital calipers next time I'm at Harbor Freight.
