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 The previous version was outdated and no longer supported.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

85 - 86 CR/WR/XC Swingarms

Hi

Question for the knowledgeable ...

I am in the process of having an 85 model CR500 rebuilt (a mate is doing it for me), we come across a crack in the swingarm that has been badly repaired in the past. I have an 86 model WR swingarm in reasonable condition. Does anyone know if these two swingarms are the same? I can see that there is a difference between CR & XC swingarms in the manuals...

Any help would be appreciated.

PS. The bike is interstate, so I cant do a visual check.
 
xc and cr swingarms are way different. as are the rear wheels,brake backing plate and spacers.
 
Ya the swingarms are different.... XC has a "quick change" style wheel where there is no brake arm going from backing plate to frame....
 
the 85-86 CR swingarm was the same the 85 XC and WR are unique to the year and the 86 XC and WR were unique to their year
the cr uses a floating backing plate with and arm that connects the frame just below the brake arm pivot
the 85 XC WR uses a flat 10" aluminum bar that holds the backing plate and connects to the swingarm about half way
the 86 uses a tab like the 87 87 but it has different linkage and shock so unique again
your best bet is get a swingarm, except the criminal shipping costs to Aus-land I have a couple spare 85 86 CR swingarms
by the way I have never seen an 85 or 86 broken swingarm, hard to imagine what happened :excuseme:
 
Some of the earliest aluminum swingarm bikes did have welded on pieces for the stay rod like on the steel swingarms before them. That quick change thing for some reason has quite a bit of wear, often anyways, for the bikes in this section 86-88 or so. I looked on the parts sheet for 1985 it looks to me like they show the bolt to attach to the stay for wrx and xc however the backing plate seems upside down.

It looks like 2premo posted while I was typing. There are auto and four storke models that may reference two stroke sheets or have their own, not sure which is the case for the swingarms.
 
and one more thing the brake cable on the CR is below the swingarm the XC WR are above
the brake arm on the backing plate is CR up, XC WR down
the pedals are very different, the CR seems to have a lower pull point than the WR XC likely due to routing
I have all the above laying around so quite familiar
