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 The previous version was outdated and no longer supported.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

73 250cr countershaft

Just found myself a 73 250cr in reasonably good shape but was missing the front spocket. Beginning to realize that these tapered sprockets are in very short supply and a pain to remove once on. I'm splitting the cases for seals and bearing and crank/rod inspection anyways and figured I would install a splined countershaft while I was at it.
Could anyone tell me which bikes had the splined countershaft that would fit?
Will a 5 speed and 6 speed interchange?
What is the part number on the shaft itself?
Thank you, your help is much appreciated. Brad
 
The 5 and 6 speed shaft will not interchange. Your options besides Vinskord option would be to convert to a 74 wr 6 speed. It has the spline output shaft. Or, find and purchase a factory sprocket puller. As long as the shaft isn't mauled or the nut over torqued the sprocket will come off with a factory puller, otherwise get out the oxy/acetylene torch.
 
Thanks, guys. I was under the impression that a 470 shaft would work. I also thought the 74 WR had a tapered shaft as well. Looks like 473s are even harder to find than the tapered sprockets!
 
Years ago John at Vintage Husky had a huge box of the shafts to convert taper to spline. That may have changed now. I think he also said you can put a complete 6 speed in the 5 speed case? I just used the shaft.

Thats true although two mods are required. One, grind a gusset thats next to the lower rear shifting fork so the fork will clear it. Two, grind a divot in the bottom of the left center case located under the shifting drum's step-feeder gear so it'll clear the case.

And to make it trick use a shifting drum and ratchet arm from a 75 or later mag. The ratchet arm gets rid of the shifting drum's detent spring and pin greatly reducing the chance of a gear only partially engaging.
