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 The previous version was outdated and no longer supported.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

TE630 vs PR7 Crankcase

Livin' It Up!
I have a 630 in the shop with a cracked crankcase because of a thrown chain. A PO (not the current owner) "fixed" it with JB Weld or similar. It's possible there was some welding attempted, but can't tell at this point. The bike is worth saving and has low hours, but leaks oil liberally, especially after running for a bit. Options I see:

Replace the left crankcase half with either used or new. Neither is available that I can find. The owner found a price of almost $2K in the EU for new cases, but there are none. I wonder if the AJP PR7 crankcases are the same.

Attempt repair of the cracked case. There is some concern about the alloy, and I think the covers are magnesium/aluiminum alloy, but from what I read it is usual for the inner cases, in general, to be aluminum. That would make welding much easier as magnesium alloy requires special care and process.

If anyone knows of a used case, even a blown engine, parts, etc. please let me know. And anyone can confirm that the PR7 uses the same casting as the 630, chime in. Made in the same factory, and sure looks the same at first glance. Thanks!!
 
Cases found, if needed. However, it looks like the case is not cracked or holed, and just damaged around the clutch slave cylinder. A previous weld repair was done but the mating surfaces for the slave flange was not done well. Corrected, I hope, and will be tested soon. I think all is OK at this point.

For anyone looking for parts that might not be available from Husky, try the SWM dealers. The 650 Superdual X is virtually the same engine.
