• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Help! Debris found in my engine - 610/630 clutch issues

BTW what should i expect to pay for the rivets and washers if they run the same as the 610?

The washers from Indy are $60 and that includes shipping. He ships first and when you get them he sends an invoice to you so you can pay with PayPal. The rivets are about $0.99- $1.27 each and you need 3 of them. You may need a gasket too. And if you have not done the balancer woodruff key mod aor check, you may buy a woodruff key too.

Noticed more vibration than usual at highway speeds on my 610 sm, suspected the bronze bushing on my clutch hub. Took it apart and yes there is too much play on the brass inner bushing (aprrox 4 thou inner and 4 thou outer). Also found 4 of the 12 outer washers were hammered to pieces, noticeable wear on the others. Lucky my dad is a tool and die maker, he made a new inner bushing that was press fit into the clutch and has 1/2 a thou clearance, with 2 relief spirals for oil to get thru. He is now working on the 12 washers. Will let you know how it all works when i get it back together. I can't stress enough to check your clutch, and update those washers. I think there is too much clearance on that stock inner bronze bushing also. My bike has 13,200 km, that's 8000 miles for you non-metrics. Ridden gently on highway, 74 km daily commute, synthetic oil changed every 2000 km. I'm thinking a cush drive rear hub would be a good long term investment. I have also noticed some damaged to the splines on the countershaft shaft.
 
Got it all back together, did the usual 74km commute, a lot less noise and vibration. Checked my cam chain while I was at it. Still at 5 notches out. Looks like i got a good one.
 
10K miles on my 2008 sm610. I've been suspicious of something going on with my clutch. After much research I pulled my case and then the clutch basket. Cup washers were GONE on one spring, damaged on all the rest and wore down to nothing. Everyone better check theirs.
 
Why were you suspicious?? Symptoms? I peeked at mine recently while replacing my clutch actuator arm and one or two spring had VERY slight mark scuff on them, but washers seemed fine for now. Didnt do the bushing cause I got the wrong one. :( Probally springtime now. Too much work before winter for much riding anyway. :(

I had to adjust the tension on the cable all of a sudden and it didnt feel like the clutch would engage properly when Id go to take off from a stop. It would make an odd sound as the clutch would begin to grab. My bushing seems fair.
 
I had sudden slack in my clutch lever and this was the issue. This is the clutch actuator arm that sits above your countershaft sprocket. It has cracked and bent. Others have had this issue as well. That part alone is about $90.

Today i dismounted clutch basket and saw the problem. I contacted my spare parts dealer. Those 12 washers that are on both sides of 6 springs costs 95€, ca 120$? Are they crazy?

I dont really understand, why are those spring washers so damaged?

Is there anyone, who made them thereself by turning? What are the right dimensions and from witch material would be the best to make them?

Here is a great source for them. Much beefier than stock and priced reasonable. Not sure if he'll ship overseas but worth asking.
