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 The previous version was outdated and no longer supported.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

I have a total grasp of what a Belleville washer is. Thanks for the explanation for the rest of us though because some probably don't. I probably wouldn't have been referring to it as such if I didn't know what it was.

I'm posting on a internet forum with general thoughts and information not to you specifically. (did not quote you) All the new huskys (KTMs) use them it the clutch pack too as does the clutch in the 449/511 (no coil springs)

Like it or not the TL would also wear in the direction of deceleration against one another too whether or not it ever establishes or reaches a point of this slippage under excessive power application going forward or being abused. It could happen either way.

My understanding is this does not slip unless under a large load like landing from a jump in a low gear with the throttle off type situations. More of a fail safe than a constantly working item. Might be wrong but think thats the intent. As such it should not see continuous wear unless it is slipping abnormally.

I don't know how far down the road with the gearbox design BMW/Husky were, I wasn't there,
but it does seem pretty clear from what Tinken has said that they started breaking gearboxes.

The limiter seems to me to be a patch repair instead of a having to redo the gears (gearbox v2.0) :)
However, it isn't too expensive to do & as a fuse it works pretty well & they are currently available.
My own concern is getting one in a few years time if it fails then.....it will be a real PITA.

You could build bigger gears, but the cost would be crazy. Better to buy a new bike :D

Not sure if the counter rotating engine, clutch on the crank and other unique features prompted this design. I assume they did as it was designed in there from the start. Only the original engineers know I guess. Tinken said 3rd gear is amazingly small when he swapped out his trans for the BMW 5 speed.

I don't expect the rotation of the engine would change anything torque wise, just the requirement for 1 more gear in the train to get the sprocket shaft to go the right way. Gear or TL gear-set, either would work.
But yes, looking at those gears, they are small.
Perhaps it was done to reduce the wieght of the gears themselves & the limiter intended to save them from harm.
As you've said, only the engineers would know for sure.

A metal toothed 'Detroit locker' style spring loaded tooth set calibrated to release at a certain pressure would likely work, but it would take some machine work & a whole lot of developement for something that really isn't that dear or difficult to replace....

TL failure at around 160hrs/5000km enduro/trail riding. Tested at 114nm bike would still loft the front but had become 'untrustworthy' in this regard and occasionally slipped under very hard acceleration if grip was good.

I have posted a positive oil feed mod on the ZipTy TL thread.
 
Berries, ZipTy does not stock TL. Your best bet is to source one through Bike Bandit as you posted in the other thread.
