Title: Driveline clunk
Post by: Jdbiker on July 30, 2019, 08:26:38 PM
These arrived in the post today from Partzilla ( thanks Alan👍) in less than 3 weeks. Total including post was $283AU. Have been feeling and hearing a distinct clunk when engaging clutch and when accelerating and de accelerating. With the bike on centre stand and in 1st gear wheel has about 2” free travel. With a longish ride coming up in a couple of months I have decided to change out the U joint rather than take chances. Will pull off the swingarm this weekend , will know then if this was needed or just a pointless exercise 😳

When my "U" joint packed up, I felt it as a buzz through the footpegs, which changed as the bike went over undulations.   See  http://ozstoc.com/index.php?topic=10046.25 (http://ozstoc.com/index.php?topic=10046.25)

Thanks for that Pete. I did read through your post on the subject earlier, hence the reason for my concern, don’t like the prospect of a blown drive line in the middle of nowhere  :eek. I haven’t experienced the buzz you describe but the clunk doesn’t seem normal nor the excessive free travel.

Took the bike for a spin today  after changing out the U Joint and no more “clunk” :like. However I don’t think the clunk was due to the old U joint as that appears to be in perfect condition with no play whatsoever. On dismantling the swingarm I found the output shaft and drive shaft splines bone dry (u joint end). This I’m assuming was the cause of the clunk noise I was hearing. I measured the free travel at the rear wheel (52mm) before dismantling and that remains the same after changing the U joint. It wasn’t a useless exercise altogether however because there was a slight oil leak at output shaft and swingarm bearings needed lubricating. Seals replaced, joints lubricated and bike running smoothly without clunk  :like

How hard was the job?
Always a pity if there aren't photos and description, but I fully uinderstand not everyone can put together a "How To" in the heat of the job.

Not a very hard job, you will need a special tool to remove the pivot bolts or make one like I did . I took my time doing this in the evenings after work , but total time wouldn’t be more than 3 hrs. Hardest bit was trying to locate the boot seal on the swingarm :H. I’ll post a detailed “How To” as best I can when I figure how to post video/pics here👍
