Öhlins Shim Stack

Does anyone know what shims should be in the shim stacks in the shocks for a 250/82 and 430/82 - or will I have to guess. My 3 pair of shocks has id nr 2x HA920 and 2x HA 1768 and 2x HA9201
Maybe anyone has a kind of Husqvarna shims stacking chart where all type of piggybag shocks are.

Best regards to all from Sten Nielsen

Hej Sten!
Not what you asked for really but this list of shim p/n's may be of some help .
I think I've seen a service letter or similar note, of how to stack shims on '81 shocks
to replicate how they are stacked in '82 shocks. Sorry I can't be more precise.

Thanks for the list Krudd but it did not help me how to stack the shim.

Regards Sten

i have current spec sheet for

Husqvarna HA4520 - 250/430 CR - 1980-82 - 445mm long 155mm stroke

This is official Ohlins specifications

I also have some original older early 80's HVA piggybacks i can check the shims in those. i think i have HA9201

Could you post a picture of the spec sheet?

Marty

I would be happy if you will send a copy off the spec sheet HA4520 either here or to my email sten109@live.dk

I have the HA 9201 stacks if you still need them. I don't recognize the other numbers as 82 250 or 430. Pic of the shocks or their original fitment and I can probably get you close.

Hi Picklito If you have the data sheet for the HA9201 i will be happy to get a copy and if you have other sugestions to shim stack, My bike is Husqvarna CR 250 year 1982 and my weigth is 92kg my email is sten109live.dk Best regards from Sten Nielsen Denmark Sorry for my bad english

Your English is better than most Americans. I’ll get you some stacks later today.

*For your size, I'd recommend replacing the 24.2 in the comp stack with a 26.2. This will partially close the bleed holes. They are pretty loose with stock valving. If you have no shims and are buying, then just use 2 holes in the 32.2d. That's not a 100% equivalent stack but very close.

Thank you very much. You do not write anything about thickness of the shim.

24.2 is 24mm diameter, 0.2mm thick.
Sorry, It’s a common abbreviation.

All are 8mm I.D.

Thank you very much

Sten,
Did you get your shocks working? What shims did you go with and how are they working for you?

Hello Picklito thanks again.
I go with this set up and i buy a new set springs and it work very good. And now i will try to put a set of Race tech gold valves FEGV-3801 in my front fork but i need a spacer FEPV-AD3802P witch i can not buy here in Denmark so if anybody have a drawing with dimentions in mm i will be very happy.
Best regards from Sten

Hi,
I saw an old post where you offered some spec sheet information for Ohlins Husqvarna HA4520 - 250/430 CR - 1980-82 - 445mm long 155mm stroke. Do you still have this? If so, I'd appreciate it if you could email them to me at: dwaltman@wi.rr.com. I'm just starting a rebuild on a 1982 CR390 and will need to refresh the shocks. Thanks, Dennis
