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 The previous version was outdated and no longer supported.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

1972 Husky 400 - Puckerbush's rebuild

The countershaft has a nut that holds the sproket. It looks like the threads are right hand (normal) but what I can't determine is why I can't get it off. I've tried a impact wrench and it won't budge.
Is the sproket part of the nut or are they separate.

The threads are left hand, clockwise to loosen, even after you get the nut off and the puller installed you may still need a torch before the sprocket will come off, good luck
 
I got the nut off but now I can't get the sproket off. I've tried heat with a gear puller and a hammer but it won't budge. I may have to cut it off. Also the cylinder studs won't break loose either. I've soaked the holes with penetrating oil and even welded a nut to the top of the stud with no luck. I have to get these two components off to split the cases.
 
The last one I removed, I had the puller tightened down as tight as I could, grabbed the torches and started to heat the sprocket untill it glowed orange, then with a loud pop the sprocket and puller flew ten feet across the shop, not kidding!
 
You shouldn't have to torch it until it's orange. Just get it good and hot. With the puller in place, rap it
a couple times with a hammer. The shock should pop it off.
 
PB - I retitled your post. If your planning on a full rebuild in here, I'll keep the thread here. If you just wanted help with the Sprocket, I'll move the thread over to the general Left kickers forum.

LEt me know what you want..

I 2nd Ron on heat and the hammer!!!

Good luck!

Update: Had to cut the countershaft sproket off near shaft and heat, puller, and hammer popped it off. 4th gear on main shaft had broken dog. Local Husky dealer wanted $140 for gear. I could get it from the guys from Oregon for $69, so I wound up purchasing a complete '72 250 WR transmission off Ebay for $56 plus $10 shipping. The 4th gear was in great shape but the real plus was the countershaft had a splined end (for sproket) rather than the tapered, so I didn't have to locate another sproket as I had several splined counter sprokets. Couldn't get the cylinder studs out but was able to lift the cylinder off the case so that I could split the cases. It's interesting that the five speeds are similar to the six speeds internally and the jig plate I built so that I can test the gear shifting and movement, worked very well with the five speed case even though the case bolt pattern was different. Here is the picture of the jig I fabricated. It emulates having he right half of the case on to test the gearDSCN2508.JPG movement.
 
The rest of the bike will be restored by a friend of mine, but I completed the 400 CR engine. New seals, bearings, and 3rd gear. Replaced the tapered counter shaft with a splined shaft. He is looking for a steel tank (rounded model) so if anyone sees one that someone wants to part with, get in touch with me.
