• Husqvarna Motorcycles Made In Sweden - About 1988 and older

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 The previous version was outdated and no longer supported.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

A couple more. 20170806_142613_resized_1.jpg20170806_142557_resized.jpg20170806_133014_resized.jpg It looks to me like the 4th gear shift fork is getting cooked. That fork moves the 5/6 gear pack by the book.
I'm not understanding what the problem is as the 4th gear pressure line doesn't look like it should be affected by the 5/6 pack. also the alignment of the 5/6 pack to the other gears doesn't look right like they are not full on gear to gear.
 
Ouch! Damage looks substantial. Its difficult to get a good view of whats happening with only close ups. Did you notice if the gears where lining properly after it was assembled? After getting the new drum did you check it next to the existing one to make sure all the roller channels were the same?

Looks like they don't line up with each other straight on, like they only engage half way. I'm confused as to why they don't line up squarely. This trans was in the motor when I got it, maybe that's why I got it! The gears are not the original part numbers for the 76 250 250 trans, so maybe that's the problem. I'm gonna have to pull the clutch and make a jig so I can understand what's going on.

So It's been a while since I've posted on this thread. Lots of other projects. I took the 450 upstate and rode it, and had no fourth gear-1st,2nd,3rd,no fourth,5th,6th. All other gears worked perfect and no amount of jerking it around would get fourth to engage. I took it apart today and found the followingView attachment 81541View attachment 81542View attachment 81543

Looks like you are missing the little roller that fits on the guide pin on the shift fork.

I have the roller. Pics are mocked up after initial teardown. I have some plexi 1/4" i'll use as center cases to see what's going on.
 
The Zep did not care about DUAL Sport cycles... Dual sport probably meant something else to them:banana:. Hahahaha

From my limited perspective while the trans is in fourth gear the gears associated with 4th are where they're suppose to be. However I do see 3rd gear is out of alignment. I don't know that 3rd has anything to do with 4th not engaging.

It hard to say whats wrong not knowing if the shifting fork rollers are in place and other details like shims and spaces are in their correct places.

Check out the attached 6spd gear position chart. It works best to flip it 180 when comparing 4th gear to your photo.

Please understand , I posted these pics because this is pretty cool. THIS IS NOT a working model at this time, it will take a little more time to finish. Shims, detent and other considerations are missing. Crash how do you post the pdf's. I could not figure that out or you would have seen it in post #101. Thanks for the help.
 
I tried to right click part of the page and insert it and it came out HUGE. Anyway looks like the drum is incorrect, in the video you can see the output shaft 3rd gear is not all the way into the outside 2nd gear preventing the 5/6 set from moving all the way over to the main shaft 3rd gear....I think.
