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 The previous version was outdated and no longer supported.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

Rear brake question OR frames

I have now replaced my rusted 1979 OR frame with a much better condition 1980 OR frame, and there is a difference between the type of rear brake used. The brake on the 79 frame I have is a floating brake, so the torque arm goes from the brake plate to a bracket on the frame near the footrest which also doubles up as the rear brake pedal mounting bracket.

The 1980 bike uses a different brake plate, and the torque arm is shorter and bolts to a lug on the swinging arm, so a non-floating rear brake.

My question is whether the brake plate designed for the floating system can be used with a non-floating swinging arm. I could quite easily fabricate a suitable torque arm, but the design of the brake plates is different, so I am concered that the floating brake plate should not be used with the non-floating swingarm. :confused:

Any thoughts and comments from any of the experts?
 
i know they change the backing plate do to issues of the hub eating through,
id have to look at the ones i have and see whats needed to make it work.
i think you have to use the 1980 backing plate with the spacer and all.
 
The 79 and 80 frame can use either type of brake backer.

The 1980 CR/OR swing-arm is 23 1/4 inches overall. One inch longer swing-arm than the 1979.

You can use a CR style brake backer on a 1980 OR Swing-arm but not vice versa. It will take a one inch longer brake stay arm. I have a brand new NOS 80 brake stay arm at home. I will measure it tonight.

The OR style backer has the spacer embedded/pressed in the plate itself. The CR uses an external spacer with a square style O-ring that let's it float with the backer. Your newer 1980 OR frame and OR swing-arm will accept either style because it has the lower brake stay mount welded into the swing-arm. IF you are using the CR style backer you simply do not use the OR Brake stay mount on the swing-arm. Some say the OR style is more durable, primarily to less moving parts.


The following is a picture of my Works Hybrid 79/80 CR 390 frame. I have a 1979 CR390 Late in Model Year frame with a 1980 OR swingarm ( longer) combined with a 1983 XC 18" rear wheel and brake backer plate and brake stay rod...

Thanks T

Yes, I was hoping it would be ok to use the brake plate I have with the 80 swing arm.

If you could let me know the dimensions of the torque arm you have, that would be very helpful. Thanks
