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 The previous version was outdated and no longer supported.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

Stuck Cylinder, Advice Needed!

Coke has phosphoric acid in it which converts rust to a blackish substance just like rust converters... You can buy undiluted phosphoric acid- it's used for brick cleaning. I use it all the time, but never thought to try on seized parts before.
 
Not sure if it would damage any coating but you can't use those pistons as they are , right ? Try an old piston first and see . Or put one of those pistons upside down and use just enough coke to cover ring land . If it does damage the coating there are companies that will recoat pistons , have a friend that swears by this . He would have a piston coated to get optimal clearances . Hope this helps , good luck .
 
Phosphoric acid is what we use to acid clean both tube nest and plate heat exchangers in the nuclear power industry. there are lots of warnings about using it on aluminium though, but this is for 24hr plus times. I think in the short term it may dissolve the "white powder" aluminium oxide corrosion that is binding the studs to the barrel. It is easily neutralized with water though.
 
7up or Sprite soda pop will dissolve the aluminum oxide powder. I think it's the citric acid that actually does the work. It saved me on a Mercury outboard engine that had been in salt water and then left in a barn for 10 years.
 
nope! letting it soak with the jack assembly on it, i don't want to break anything so i'm trying to be patient with it LOL
 
I'm thinking silicone around the studs on the air cooled cylinders. Thick enough to seal the gap between the cylinder and the head.
