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 The previous version was outdated and no longer supported.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

430 AE wear items.

I have taken the transmission cover of my 430 AE, 1986 model. I gather that the main clutch drum is the part that wears out first, is that right? and if so how thin can it become before it is bu#####d? Mine seems okay but I do not really know what is good or bad. All advice gratefully received.
 
Pretty much what the above post states. But it must be talking about the first gear drum not the main drum. In the 430 and 500 the shoes are smooth (and magnetic ie iron compound most likely) and the drum has a spiral groove cut into it,again first gear not the big drum on the next shaft back. I am guessing perhaps five or six turns. These grooves I figure pull oil in and/or out and keep the oil from overheating and the first gear clutch for that matter. The earlier versions had a smooth drum and the shoes had slots on a slight angle to accomplish the same general thing. Those shoes which were bronze or similar material could be touched up with a hack saw. The tips of the engaging pieces for the starter mechanism might need a little weld and grinding or filing to get back to the origional profile.

The swingarm and linkage bearings and the hard parts they ride against are kind of wear items especially if the hard parts they ride on aren't in great shape. Of course that might be different with different terrain to ride in/on.

Thanks Michel and Fran, at the moment the first gear drum looks in pretty good condition, I can see the grooves quite clearly, does any one know if there is a way of refurbishing them or is it replace with new?
 
The kit with the springs, drum, shoes and little nuts and bolts cost in the area of $150 retail at the dealer around the time the bike was 10 years old. I did talk to one guy and he thought it was a real simple thing to make with dies and presses. I was thinking it might be made on a metal spinning lathe. Sure you could put a used one in a lathe and use spray metalizing technology, could possibly even choose a better material if that technology is applicable. Any shavings from that basically go through the whole transmission. I think balancing it (and the shoe assembly)would be important, the 500 has two needle bearings for that drum on the crank, the 420 has two bushings but the 430 has a shorter crank stub and only one bearing. The others also have a little pocket in the outer cover to collect oil and a passage to feed it into the crank end and lubricate some of the stuff in that area. Not sure if this missing oil input because of a water pump getting put there complicates things. Also those pins that the shoes pivot on (not in the kits) tend for me to shed little bits of what would be like the head of a nail. Probably the drum could be mass produced cheaper than refurbishing it.

Ideally getting an engineer to examine the whole set up and the predecessors and design a new and improved kit would be great. There isn't the issue of the starting gears decaying and the magnesium cases going to crap like in the standard shift bikies.
 
New drums can be machined out of solid steel. Mild steel will work fine for the average vintage rider who rides only a few races per year. You do not need to press them as this is a manufacturing technique used when pumping them out by the hundreds. Don't even bother trying to used Cr Mo and heat treating - you simply won't use it enought to warrant the cost. The best bet is to keep your eyes peeled on eBay. They come up from time to time. Cheers Steve.

These people on ebay
tritrophy were just offering NOS 1st gear clutch drums for around $60 if I recall correctly.

Yes, if anyone could find a complete kit or other auto parts it would be Dave at Tritropy.
He also has other parts that are not advertised in his store. Unfortuately those drums are for earlier Autos.
