husky 430cr

Hi all, ok here goes ive just bought what I beleive to be a 81/82 430cr.The problem I have is with the engine number its 0945 6800 ? Ive checked with all the husqvarna web sites and the serial number prefix doesnt appear? The frame number is so lightly stamped I cant see it. I have no reason to doubt the bike what so ever its reasonably tidy. The area where the engine number is stamped hasnt been tampered with as you can still see the machine marks in the flat area where stamped the numbers are clear, if anyone can shed some light on my problem please reply thanks all BarryRanson

That number makes no sense to me from what I found. Engine #'s should start at 2086 for 1981 or 1982. I looked at this chart http://www.huskyclub.com/model.htm

I know my old 82 430cr started 2086, im stumped

I think it is a newer case in later years that someone used.

Yep newer case from like 86 on!

I have a couple of frames that were stamped crooked and hardly see the numbers.

You could be right ill have to do somemore investigating thanks

Go to www.husqvarna-parts.com

The numbers 0942, etc says it's an 83 500?

The 430 air cooled has nine (9) cooling fins on the cylinder. The 500 a.c. cylinder is way taller.

Darn everyone has the luck.

The 500 has 10 fins on the cylinder and is taller but has the same bore size as the 430 but there is nothing to keep someone from using 500 cases to build a 430 upon. The number of fins on the cylinder will be the key indication now

I been wanting a 500cr bike it maybe a Honda. I had a husky 85 500cr but the honed cylinder to the new piston was .001" out of spec. I sold the basket case. Big mistake.

I have a story about engine case numbers I just purchased a 2087 engine.
There is a 2087 WR MP it's a military police. Then there is another 2087 that's a 430 WR. I got a 430.
The nine cooling fins was the giveaway. I purchased a advertised 250 cylinder that had nine cooling fins. It's a 420 cylinder.

Just some thoughts when looking at parts.

my motor 430.
number=
2086/...
or
2087/...
for
CR/WR/XC

This one you mean ?

When I saw your new one I thought it had a XC frame as it had the back loop. Good to see you got one, hopefully not too dear either.

That's the project bike I'm building. That's the cr frame.

Yes thats the one steve the one ive just bought is not a wr or xc the rear frame loop is cleverly made to insert into the ends of the frame & pick up on the existing bolt hole! It just unbolts straight off. Everything seems correct with the bike original wheels 17" rear, exhaust is original. I know the left hand engine casings are vunerable to damage & ive checked all the husky web sites but I cant find a serial prefix 0945 im baffled!

Thanks big bill, yes its definitely a 430 9 fins the serial number 0945 doesn't tally up with anything though I understand someone could of built the engine up out of bits but I just cant seem to find what the cases were from? Thanks for your help anyway

The 0945 number is so close. You have a 430. It's a replacement case.

Like I said before I seen the 2087 number mean 250 wr mp and ifa 2087 430cc wr. Go figuring there a mix up with the frame numbers along the way I heard it years ago.

Hell file them off and stamp your own on there!
Remember a guy kept saying he needed xyz numbers on a set of cases. Guy said, I have a set and you tell me what numbers you want on them. He went back and filed numbers off and re stamped them.

Does the year of the frame numbers need to match the case numbers exactly? Does that make the bike worth more?

the only thing that gives your engines id away without measuring is the 9 fins.
the engines are not numbered to the frames. the frames state what year and model they are. long as you have an 85 motor in an 85 frame, it is "correct". i would not be surprised if husky didnt always match this, or as ruwfo says it is likely a repair. really unless you are sure of the bikes history, the engine numbers really dont mean much as any 250 and up transmission could be swapped to any cases, or vice versa. i dont even think theres anything from stopping you from swapping ac or lc cases other than the swinger bush size between dual and single shock. only difference with the 250 and bigger brethren is the extra web in the crank.
an engine could say 84 500 wr but have a 430 crank and jug with 250, 400, 430, or 500 cr, wr, xc running gear easily.

The 250 crank in the newer 80's case has smaller crank balancers you can't put the smaller 250 crank in the larger 430/500 case because the larger volume crankshaft area won't charge the cylinder fully. But we can use the 250 case to make a 430/500 if we remove one of the double walls. Then it becomes a big bore case.

Now the (9) nine cooling fins. The 390/ 420/ 430 all have (9) nine cooling fins. The early 430 uses the same double block reed cage as the 390/ 420.

All air cooled 430s use the same reed as a 390 because its essentially the same cylinder with a bigger bore and a slightly taller deck height to match the longer stroke.
