At the end of last year a clunking started to develop in the chaincase. So i took the chaincase apart and the chain was a little bit loose but not much. So i tightened it, and ran it across the field and it seemed to go away. The next day the snow melted and i put her away for the year. Well, after tearing the old track off and putting the new one on, i found the problem. The brake seemed to have a little bit of play and when it was revolving it would move a little making a light clunking noise. At higher speeds it seemed to correct itself, but at low speeds it was a consistent clunk, clunk, clunk...the faster you went the faster the clunk until eventually it stopped at about 30 miles per hour. Anyhow. So i went ahead and decided that the brake must be wore out and went ahead and got a new brake. The brake isnt new, but i put a racing hub on it that is Brand New. Also i order a new sliding key to replace the old one. Figuring...something must be wore a little and is causing this thing to be loose and by replacing the old parts the problem would be fixed.
To make a long story short, I replaced the old brake and sliding key with the new and the brake is still a little loose, and the clunking is still there....I turned the jackshaft as fast as possible from the clutch side and noticed that the frame near the jackshaft bearing was moving slightly. I know this is not right. Which tells me that the jackshaft must be bent slightly because its pulling back and forth.
A little history, the guy i bought it from told me that he hit a concrete block in a ditch in the U.P. The trailing arm on the chaincase side was bent pretty bad and i ended up replacing it. Im wondering if the jackshaft might be bent?? If so, thats not to hard of fix. Or if its just worn out and needs to be replaced. One thing i did find on the secondary was the guy pulled that sleave out and the secondary wasnt running with ANY play. any and all help is greatly appreciated.
