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 The previous version was outdated and no longer supported.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

Engine cases

To see the web we are discussing it is necessary to separate the case halves and photograph the surface that the center gasket goes on. The crank cavity goes all the way to the bottom for the 400, 430, 500 while there is a web as we are calling it that reduces that semi circle by about 3/8 inch for the 240,250,260 or whatever they offered.

see how in upper case half (left case side)
looks like a double wall around crank....that's the "web" used in 240/250 motors

Remove the inner web and just use what melds with the case bottom and you have a 400/430

Too easy

Problem is information without pictures are harder to understand. This case is stamped as a 250 - 2089 yet didn't have the internal webbing - so not untill Joe posted a pic to describe what he was explaining did it become obivious.
 
Or the web might have gotten broken from piston skirt breakage so it might have been removed for a more severe case than I corrected a few years ago in one of my 250WR engines
 
So in order to make my 250 a 430 i need a 430 crank ,rod cylinder piston and top ? Everything else is the same ? /A
