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 The previous version was outdated and no longer supported.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

Thread sizes rear axle and swing arm axle?

Husqvarna
Pro Class
Does anyone know the thread sizes on the rear axle and also the swing arm axle?

This is for like an 80 thru 83 husky.

I measured last night both but am about 1/2 mm off that could swing either way in size.

Thanx
 
the swing arm is a non standard thread . not sure bout the rear axle .
when i lost a swingarm nut it was easier for me to make one than it was to buy one as i happened to have the tap .
 
I will check diameter and pitch when I have a chance, Kinda busy dog sitting these days. I have several swingarm pivots and an axle all in the same shoebox in my workshop.

Thanx, I want to run a die over them and when they come back from plating.
 
Rear axle is 15mm in bearing contact and thread is most likely 14mm X 1.0 pitch. Not sure as I did not have a chance to measure yet but there is a step down from bearing to thread and the pitch is fine enough to be 1.0 but will check with a pitch gage soon
 
The axles are 15 mm which is the bore of the 6302 bearing in the wheel. The dual shock swingarm pivot is 12 mm and the mono shock swingarm pivot for this section and at least up to 1999 in the older single cam section is 14 mm. I am sure they are all some logical number of threads per milimeter. Probably one or one and a quarter milimeters between threads If you can measure 10 threads it makes for less error. I don't know about that step down business.
 
Just bought thread pitch guage.

If my calculations are correct Bryll was correct on swingarm 12mmx1.0

The rear axle threads lean more to 14mmx 1.25

Wish someone could verify to be exact?
 
Hi Darin,
Another way to double check is to add the thread pitch to the ID of the nut. Generally the tap drill size is the bolt diameter less the thread pitch. So if you have a 14X1.25mm bolt (axle) the ID of the nut should be close to 12.75mm.. I think all of the bolts I have measured have been .12-.20+mm under their size.

The swingarm thread is M12 x 1.0mm, I bought a box with M12 x 1.0mm nylon lock nuts for my bikes.
I will order some samples of the M14 x 1.25mm and M14 x 1.5mm nuts to verify the correct rear axle thread.

Good tip! Thanx for your imput.

Great, that's helps a lot.
 
STOP! It's M15 x 1.25m/m. Nuts should be 24m/m A/F
Front and rear wheels are the same, with a 11m/m thick nut on the front.

Definately!!!

I would go with Andy.
he looked at pics of my Husky before i bought it and told me what was correct/incorect, and when I wanted info/sprockets he was extremely helpful and despatched them with the rider pay me when you receive them. NOW that is an old fashioned level of service and product knowledge that you just do not see these days. Thanks Andy, plus I see in CDB magazine (UK) he has just got the inlet/reed manifold boot remanufactured.
(apologies for going off topic)
 
Don't know about the 'M' size but my 85 model swing arm bolt is 14mm thick (according to the verniers) & I used a 1.25 thread cutter to clean the thread up, came out beautiful.
