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 The previous version was outdated and no longer supported.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

Hello everyone I'm rebuilding my 77 250 cr. I split the case's and low and behold case cancer.It's not to bad the mating surface's are fine it's inside the crank case that has the pit's.My question is what do i use to fill it with that will hold up JB weld? Or is there something better, any responses will be appreciated
 
The only thing I found is gun coat. Please check with the former Kal Guard company - its split now and they are located in Taylor tx outside of Austin.

Yep its the same coating used on guns - its acid proof , chemical proof. But its not a filler

Checked all sources - talking with the vintage F1 folks they use this on their old mag cases from the 70s inside and out. Its the only thing stops Mag - turning to powder.

Most all old huskys that do not have a coating in the lower crank area but have a patina of old two stroke oil and carbon that seems to seal this area.

So far I have replaced most cases that are too far gone.
 
I have just assembled an 88 husky with some pitting withing the crank cases - thought it to be simply poor castings. There is a hollow section within the same casting which is filled with an epoxy resin (by husky I assume) its fine so I's say any exoxy like JB weld wouyld be just fine.
 
I don't think it's an issue, if the mating surfaces are good. Put the motor is put back into service and you will not have any further corrosion.
 
If it is inside the crankwell, I would use expoxy over JB Weld. If you sand the JB Weld, you remove the seal coat. We used Duro 5 minute epoxy in the 70's to stuff the crank balance holes to raise lower end compression. I can personally attest in that environment the epoxy is extremely durable. 3 inspections over an 8 year time period (constant use) showed no degradation of the epoxy
 
I want to thank you guys for the info I am going to try some high temp epoxy nothing ventured nothing gained when I get it runnin I'll let you know how it turns out. thanks again.
Tom
