1986 430 Hubs

I am looking to finish my 1986 Husqvarna 430 AE here this winter, and the big hiccup is hubs. I want to replace the tires, rims, spokes, hubs, front and back. Really everything is buggered by the hubs. If I can figure out what hubs will fit, everything else fits in nicely. I want to be able to change the size of the rear sprocket and replace the drum with a disc, I have someone who can weld a mount onto the aluminum swing arm, but I am told the size of the axle means no hub will fit, as I recall as what I am being told.

The rear axle I believe is 15mm, I am unsure of what the front is. I would like to verify sizes of the axles front and back, there is a Husqvarna dealer about 2 blocks from me that say if I figure that axle sizes out I can bring in a caliper and measure the axles and everything on the new bikes because the wheels on the new bikes look almost like they would fit, and they are Excel, which told me that what I want to do can't be done, and then I am also going to start calling companies and seeing what the specs are on the hubs for axle sizes. As an Electrical Engineer I am used to seeing datasheets on components, I am somewhat surprised there aren't anything I can find on dimensions or specs on anything as far as hubs for bikes, like I mean are every Japanese bike, every newer bike so standardized that parts are virtually completely interchangeable and data on parts are not required? I am new to changing out motorcycle wheels, but this seems far more difficult then it should be, but I could be, and probably am, totally wrong somewheres.

The rear hubs go back as far as 1982 and there are both CR and WR type. I find few differences between those and what I have on my 1985 400WRX and 1986 400WR. If the axle sizes are different you can likely accommodate that by changing the axle bearings to fit the axle if such exists

I want to change the hubs out with something brand new after market, looking at Tusk Impact Hubs right now. I am unable to check axle sizes off my bike right now and can't find the info anywhere. I have found info on the Tusk Impact hubs, the rear comes in 20 or 25mm size and front in 18 or 20mm if I am correct. I kinda just want to know axle sizes so I know if they will fit or what I would have to do to make them fit.

there is a thread on that right now
and i am looking at 2 options one change the bearings like they are, two mill the swingarm axle slots to fit a 92 rear wheel assembly which i have

I seem to remember jens ries doing a rear disc conversion to his tc500 using an oldish rear wheel and some welding to the swing arm.

the later wheels all have big axles c/w the older wheels. husky axles are weird. I lost a nut and couldn't find one so I just retapped the axle to std metric 12mm I think.

I upgraded to a rear disc on my '86 Auto. I opted for a left hand rear brake set up. I used a 1998 wr250 wheel. Had to bush down to the smaller axle size and machine the caliper holder plate a little thinner. It works great.
Here's the thread: http://www.cafehusky.com/threads/racing-86-husky-in-vet-a.33375/page-2#post-427015

Ok, so if the axles on the bike are both 15mm, I should just look into a hub with a width that fits and bush it or change the bearing to fit? Seems like most hubs will fit, they just might need a little finessing.

That is excellent! What material did you bush them with? Would Bronze bushings work or would bronze be too soft? Stainless steel? It seems like as long as I get a hub that it the right width to fit between the swingarm and fork, and has a larger hole then the axle, I can just bush them to fit the axle. I guess it would also go without saying a flanged bushing is need to bush the hub to the axle, and some regular bushings can be used for spacers, correct?

I'm currently swapping in a rear wheel from a '95 WXE into my '87 WR430. The '87 is indeed 15mm axle while the bearing diameter is 42mm on both. My plans call for swapping in the 15mm id bearings into the new hub then turning up spacers as needed. Remember your sprocket needs to be your datum line; set it in the same position (left/right) as your original with respect to the swingarm and then you will be able to arrive at the space available on the brake side. I'll do pics soon.

Yes, got to keep the chain aligned. I do have to grab a smaller sprocket in the range of 50 to 55 teeth to replace that big 60 tooth sprocket, I need to adjust a little bit where it shifts at, how much power it has and how fast it goes for what I have planned.

I am really liking the Tusk Impact Hubs for price and the reviews I see on them seem to say they are a great hub for the price and that leaves more money in the budget for a set of Excel Takasago Colorworks rims and spokes to be laced on and a set of Heidenau K60 Scouts. I have sent an email about the Tusk hubs to see if the bearings can be pressed out and changed or whether I would have to have a set of flanged bushing purchased/machined to have them fit the axles. The bearings from the original bike I wouldn't use though, I would grab a new set because I don't know if the OD would be the same on the new hub and it would be nice to freshen up the bearings anyhow if I am able to swap the Tusk bearings.

I used aluminum for the spacers/bushings. Just had spacers made up that extend into the larger bearing, remember the bushing portion of the spacer has to extend all the way through the bearing and into the spacer inside the hub between the bearings to keep it centered.

Yeah, that is why I was wondering about flanged bushings.

I've done the exact same upgrade to my 86 auto as palito and we both used the same guy. I however did not use a husky wheel, I used a stock honda crf250/crf450 rear wheel and had spacers made to fit just like palito. Stock axle from the auto was used as mentioned

Has anyone tried doing a completely new aftermarket wheel set? I guess it doesn't matter, if I could find a wheel for something like the CRF450 like you were able to work, then it goes to reason that the after market one that bolts onto the same bike should be able to be modified to work as well.

Picked out some Tusk Impact Hubs for a 2001 Yamaha WR426F, with a set of gold 17 x 3.50 Excel rims for front and back.

Maybe it was just the rim that I was using but the tusk rim off a newer honda was to wide and would hit the rear brake mount even without the spacers. Maybe those rims you have picked up will work just fine.

I am only using Tusk Hubs, the rims are Excel Takasago Colorworks. Haven't ordered the rims yet, I am checking on sizes available. I think once I get them I will have to send them off to Buchanan's Spoke shop for custom spokes, but I am not sure if I can find spokes that will just work as is.

Hi I have a complete 1986 Husky 430wr all original, but I did sell the engine out of it. If u are interested in and parts just let me know. Thanks for your time

Sorry when I say rim I'm talking about the hub. I can't remember 100% if the hub was aftermarket aswell but I know that the hub was the issue with it not fitting in the frame. With the rear brake caliber in place plus the spacers I had made up was all to much to make it fit properly.
