• 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 The previous version was outdated and no longer supported.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!

Can't Solve Dragging Clutch

Are the new springs identical ? Same height etc? This reminded me of a conversation with a friend about clutch drag on his bultaco , he would adjust the springs so the pressure plate would lift evenly . I'm not familiar with a bultaco clutch but sure I could ask him just how he made the adjustments . After rereading this post a few times and looking at the pictures that you had posted brings me back to the pressure plate . The Husky design has the flat needle bearing to spread the load and on yours the lifter goes into a ball bearing . When you put the lifter into that bearing , can you get in to tilt to the side at all in relation to your pressure plate ?

Yes the new springs are all identical. The lifter fits very snug into the bearing. There's no play.

Correct. There is much more play in the opposite side of the lifter and it's fitment into the clutch rod tube. This area is so loose it doesn't seem it was ever supposed to be a tight fit. If I squeeze the clutch lever so that the pressure plate is moved outwards I can push the pressure plate in any direction by a good 15mm (against the pressure of the springs). There's no "guide" keeping it straight.
 
can you see where the movement is coming from ? On the parts fiche that you posted there seems to be 2 number 6's , one that you circled in red and another one that looks like it would hold the bottom of the spring in place, they are also in place ?

Yes, I made a punch mark on the outer basket and inner basket where there was minimal movement. Then I rotated the inner basket 180 degrees, reassembled and saw that the movement issue followed the inner basket. That's what led me to finding the grooves above. After filing them down I can't see a difference in the movement. It all looks pretty even.

The fiche is confusing, one because it's not the same clutch that's in my bike even though that diagram is for the same 2001 TE570. From what I can tell the OTHER clutch uses a spring-washer-bolt stack up. The washer being #16. Mine uses a spring-cup-bolt stack up where the bolt head is recessed into the spring by the cup. Those cups are the second #6 you're talking about which should ACTUALLY say #61. It's a type-o. #61 is listed on the following page as "cup".
 
I just found a new inner clutch hub on eBay for a "400 / 450 / 510" that looks identical. Only $35 shipped. Part number is #8000A3801. We'll see if it's the same when it shows up.
 
I was looking at that thinking it was a typo and should be 61 . Good luck , hope the new inner hub solves it for you . I could be wrong but can't help but think that extra movement isn't helping your clutch release all the way hence your clutch drag .

Any updates? Did you manage to fix the damn thing?

That other hub I ordered above turned out to be an identical design but like 10mm deeper. So that won't work.

I haven't been able to track down a new hub anywhere. Not even from the usual guys I go to that have NOS Husqy hoards.

That is some bad luck.
