    Intermediate Shaft HOT

    While riding today I started to notice a whirling sound coming from the pump area. It started suddenly and almost sounded like a loud gear wine that changed pitch with RPM's.
    One thing I noticed that I had never paid any attention to before was that the intermediate shaft in the hull was HOT. Mainly hot back near the bearing housing on the midwall. You could only touch it for a sec or two.

    Does this sound like the bearing in the intermediate shaft is going out?

    Thanks
    Doug

    Should at least grease that after every 3 or 4 rides, just a few pumps will save you from having to get a new one.

    I thought the grease does not go into the bearing itself, the grease helps prevent water intrusion only, that`s why there is a specified amount, pump to much and you`ll pop the seal, correct?
    initial 10 hours = 1.12-1.18 oz, and .20-.27 oz after 100 hours or one year.

    Good thing I`ve done like billy and gave it a couple of shots every few rides...

    The bearings are dry and friction is causing the heat. I always grease the intermediate shaft every other ride with a shot or two of grease. Mine is 9 years old and still holding up well. The grease also helps keep the seals from allow water intrusion.

    They can be rebuilt. Parts in the microfiche in the online store. Or see if you can locate another intermediate shaft. Easy to swap out. If you choose to rebuilt it, hand pack it well with grease upon assembly after you press in the seals and bearings.

    nope. When I had my shaft removed for the conversion to Ted Thompson, I could see the inner race on each bearing.

    so then the bearing does get greased?
