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 The previous version was outdated and no longer supported.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

Crankshaft right-side dimensions

As a side note, the Sachs 100/125 has the same size and taper crank end as the 13mm "small" Husky crank end, the PVL part number is the same.
 
My '81 through '86 125/250/400/430/500 had same shaft. The 78/79 390had the larger shaft. I believe my '77 250 with the motoplat was like the '81/'86 taper.
The earlier pre '75 is different? #3?

I didn't say they were all the same. The pre '77 shafts I'm not sure about.
 
'82-up are not the same as '81-older, there is a 2mm difference in shaft diameter, I know this because I tried to swap them and they wont interchange. All Femsa points bikes have 20mm shafts, that includes 250WRs up to '77, this is also the same size as the 390 big Motoplat. Motoplat bikes from '71-'81 (except the 390 and some 250WRs with the 20mm shaft) had the 13mm small shaft. '82-'88 had the 15mm shaft. The Husky Club list (and the Husky microfiche) says the 125 kept the same small shaft all the way to '87 but that is wrong, I have an '82 and an '83 and they both have the same size as my '82 430. I also know for a fact that my '76 175 has a different size than those bikes because I tried to put the PVL off the '76 175 on the '82 125 and it didnt fit, the '76 has the small 13mm shaft and the '82 has the medium 15mm shaft.
 
It's confusing. I put a 430cr motoplat in a 85/125cr internal flywheel.
I had one rebuilt '74 250 husky. I bored it installed a new piston. Sold it before I started it. I think the early 360 had the same shaft as the 390.
Maybe we should ask for a sticky with info on this?
A sticky with bore sizes and piston clearances?
 
The 430 does have the same shaft as an 85 125, and yes, the 360 also has the big shaft like the 390. It's confusing for sure.
 
In the end, my 82 wr250 has a 14.1 mm diameter on the smaller end of the taper. Not the 13 or 15 I've heard it called. The Power Dynamo (MZ) flywheel from the small shaft kit fits just perfect.

I'll try IRC for the 17 inch tires. That will be for my other Husky (the 240 WR) which has the smaller rim (for Canada and Europe only)? As far as seat foam and gaskets etc. I have found the DC Plastics website sells some items other than plastic but not sure of the authenticity. Will need a seat base as well.
 
I don't know where the 20, 15, and 13mm measurement is taken on the shaft but I can say with 100% certainty that there are 3 different sizes of Husky right side crank snouts and the flywheels will not interchange.
 
But what if the cranks were swapped. Some 250 cranks in the older case will swap?

I think the taper is measured on the Small end, but being metric things are done different then in the U.S.
We had problems machining metric tapers on couplings in the shop on the large dynamometers I built. One DC motor was equal to 28 427 Chevy engines torque wise. This DC motor we used as a load motor to test new AC motor designs.
These took 14" diameter couplings. I spec out 48" diameter couplings for the Disney tower of terror that we designed and built.

But English and metric measuring is done different.
 
The stators are difficult to repair as all coils are potted with a difficult to remove compound. As long as the stator tests well with an ohmmeter it can work using pitbike CDI and coils. I actually only need a rotor to replace the one on my 84 250WR that lost a large quantity of it's magnets.
 
the 125 and 175 are always the freakshow in the husky land of confusion. As Brian says same medium shaft on 80s bikes as on the 80s 240, 400, 430 but the mounting plates are old school non primary kick....
 
Right, and even though they changed to the medium shaft on the 125 in '82 like all the other sizes, Husky never updated the microfiche and shows the earlier small shaft all the way to '87 on the 125.

We are waiting for the new seat foams to arrive....

I am told - 'soon'

All the rest is in stock except the tyres...

Thanks Andy but to order somerhting all the way from the UK is a non-starter for me. I'm looking for US or Canadian parts suppliers only.
