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 The previous version was outdated and no longer supported.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

FREEWHEELS DIFFERENCE BETWEEN 390/420 AND 430/500 AE

I have a 430 and a 420 automatic motor.
When I have opened the 2 motors, I have compared
the gears of the 2 motors. The two 430 freewheels are the same
than two 420 freewheels . 420 motor has 3 freewheels ( one more than
the 430).
But when I look at parts lists, the parts number of the
freewheels which are identical are differents.
420 parts numbers are differents from 430 parts numbers.
Can someone give an explication ?
420 freewheels are easely avaliable, not 430 with 430 parts number.
Pics enclosed is 420 gears on 430 gears. Diameters are identicals.
Thanks
Michel

It has been a long time since I took them apart. Actually I might have stopped (halfway through) taking them apart on the logic if it isn't broke don't fix it. I am seeing three then two then one sprag or one way clutches on the 420 and three then two sprag or one way clutches or freewheels on the 430. I doubt I can answer your question but which number on the enclosed picture upper and lower appear to be the same?

In general is there some document in the teck reference section as to what part number has superceded what other part number. Or the opposite of superceded, going back to a prior part # Some on line parts suppliers websites seem to have some of that programmed in. It is also an advantage if you find a dealership which was in business back then in the hope they might have read and memorized all the service bulletins. It is not just husky or even just motorcycles, this phenomenon.

420 FW #40 *16 12 548 01* is the same that 430 FW#37 *16 11 265 01* .
420 FW #43 *16 12 547 01* is the same that 430 FW#40. *16 11 264 01*

I see less gears or speeds in the later 430/500 but one more freewheel in the later design in first and second gear. 420 #40 one piece 430 #37 two pieces.
