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 The previous version was outdated and no longer supported.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

390 piston pin - Spacers not thrust washers ?

I am rebuilding an 8O 390 CR engine. Confused by Husky as this piston uses not thrust washers
on piston pin but spacers They are Aluminum and slide inside the rod bearing bore.
Yes they fill area and space but?

But why not use the wider bearing from the 430 and not use spacers?

Thought I would replace them, but seems ok. Had a wear mark on one side I removed They don't seem to be available anywhere. Have to make some I guess for future.

Any comments?
 
The thing to remember is that the rod is piston centered and allowed to float on the big end of the connecting rod. The spacers position the small end central within the piston. The piston will then center the rod within the crank. The rod should not float at the small end, but at the big end.
