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 The previous version was outdated and no longer supported.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

1981/82 420 Auto rear shock hardware?

Husqvarna
AA Class
I'm putting back together my 1981 420 Auto. It's had a hard life of many owners so some of the mounting hardware is sketchy. I've reviewed the various parts and workshop manuals but I'm not seeing the detail I need to make sure what the proper nuts, bolts, washers, bushings, etc. are for mounting the rear Ohlins piggyback shocks to the frame and swingarm. Pictures are worth a thousand words as they say! Any help????

Ohlins usually have Heim joints at the top. These are available from various suppliers. When you press them into the top eye there is a void both sides. There is then a 'top hat' bush with a fat o-ring that gets pressed into either side. This will allow a little movement like a ball joint. The lower eye has a metal/rubber (metalistic) bush pressed in.
When I rebuilt the piggy backs for my Auto I changed the lower eye for an HVA Factory one. This will accept a heim joint the same as the top. Remember to keep them well lubricated with waterproof grease. Use new nuts and bolts on the lower and new nuts on the top.
 
Those are nice, I did'nt know Andy made them accept heim j's at the bottom. I will go with these in the future when mine where out. This is what I went with urethane bushings at the bottom they seem to be holding up well so far tho not many riding hours on them.photo (10).JPG
 
The shock tops have the heims in them. I also have two different sizes of O-rings and one set of top hat bushings per shock. I know I pulled out a metal sleeve from the shock's bottom eye when I took them off. I have one of those.

What I could find in the manuals wasn't much information. For example, the bottom eye shows a one piece part, #13, which sounds like it might be three pieces?
