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 The previous version was outdated and no longer supported.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

Lower end spacers / Washers

I am installing my new 1st over piston and saw to my surprise in my manual that there is apparently supposed to be two spacers/washers between the conrod and piston.

I did not have these before I broke the engine apart for a full resto and hence does not have the size for them. Parts manual only lists them as washers aswell :(

Anyone able to shred some light on the size of these and if they are really needed ?

Thanks
Lars
 
I just double check the 81-82 parts manual & only the 125 & 250 get the spacers , the 430 Does NOT. Picture show
spacers (16 10 674-01 & 16 10 971-01), but when you go to the part number call out the 430 are blank, meaning
there NOT used. Same for the 83-84 430 & 500 bikes too.

I did the same thing when i did my 500CR, and look every where for what i did with the those spacers,that didn't exist LOL.

Aahh, sorry guys, my question probably won't make much sense without typing the engine spec...sorry!

The engine I broke apart was an '82 430 CR, but cases were bad so bought a good condition engine case, probably an 81' or 82' but not 100% sure on the year unfortunately. Installed everything + 6 new gearbox gears, new primary drive etc but crank and lower end bearing was very good condition so kept that as is.
So summing up I probably have an 82' crank in a 81' or 82' engine case.

Rebored and honed to 86.5mm and bought a wossner piston kit (honed to 0.004" gap).

..And now I am probably missing these washers, but have a good set of different shims so maybe I have what I need if I new the size of the washers.

Thanks and I wish you all a great weekend, hopefully I shall start this bad boy up sunday following a 100% restoration :)

Husky John,


I was hoping that as well, but then I looked at the parts catalogue for 81' 430 available here on the technical section and it actually lists two spacers also for the 430. It doesn't though for the 82' as far as I can figure?

Thanks!

Wildebeest,

Nice thread, saw the spacers! You fitted them to a 0.3 mm gap as far as I can figure from the pictures? Might be in the garage for a while this evening to make some myself, depends on the misses I suppose..

By the way, off topic a heck of a alot.., but I saw you had the same electrical screwdriver I have in one of the pics (14.4V blue one). Couldn't help to laugh about it since mine packed up yesterday after 10 years building half an airplane and a house with it. It put up with alot and surprisingly sturdy for the price. Its a small world out there.

Thanks,
Lars
 
It depends on which top end bearing is used.
Later models used a wider bearing and they were not needed.
Would always replace with wider bearing and leave washers out on top end rebuilds.

To me, if you press the crank as per 2T manual at 58mm+/-0.1 flush crank cheek to pin then you have lost control of big end clearance (normally controlled with thrust washers and/or the pressing of the crank) then this should be controlled by shimming the little end (wrist pin) to centralise the con rod? If you have both floating and un-toleranced then surely asking for trouble or does that work on these engines?
 
Guys,
The bearing I have with the wossner piston had a 1mm gap between bearing-piston. I ended up shimming the bearing on both sides to a 0.2mm gap. The rod will still float quite signifficantly due to the play in the lower and upper end bearings, but at least now the bearing float is controlled.

Have a great day
Lars
