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 The previous version was outdated and no longer supported.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

Cylinder head studs and nuts

I just pulled the cylinder head and sleeve from my 1984 CR500. Three of the nuts pulled the studs out of the case and the fourth one came off leaving the stud in the engine case. I've got one nut off of one of the studs but I'm having issues with the other two. I'm assuming it's preferable to have the studs fully installed in the case and then tighten the nuts rather than have the nuts stuck on the studs and use them as long bolts.

Anyway my question is, Does anyone know of a source for studs and nuts? just in case I break these ones.
I've used heat and penetrant but it appears the nuts are fully threaded on the studs.

Thanks in advance for your responses

If their the same as the 83 engines I have a set if you need them. I just smack them lightly a few times with a hammer then use some penetrating oil and they usually come off.
 
I guess I posted a little prematurely. I spent another hour in the garage and I was able to get them all apart and chase all of the threads. The nuts were so far threaded on to the stud that they were trying to make new threads.
I took this apart to replace the cylinder base gasket because I could see smoke coming from that area while it was running. I have a feeling that it wasn't torqued right by the last guy due to the stud/nut not being installed correctly.

Thanks tommie for the offer, fortunately I won't need them.

While we are on the subject. I was sold the incorrect clutch cover gasket from Malcolm Smith Motorsports. It isn't worth the gas money to try and return it, so if anyone needs a new gasket let me know. The part number is 161079201 and it should fit a 125.
I might start a new thread for the gasket if I get no response.

Thanks again

Now just to specify. The studs have a long threaded end and a short threaded end. The studs were installed with the long end going into the case.
Is this correct???


Thanks
Adam
 
Adam,
I want to say the short end goes into the engine case but will have to go check out a engine to be 100% sure.
