430 LC in the post.

[Wildebeest90210]

Came in the post from Spain today. An 88 430cr made in Sweden eng no. 2201..... saw it, bought it, not sure what for but will be stripping it fairly soon. I guess the bottom end will be the same as an air cooled 430? Not even checked if it's6 speed yet? Any advice or tips about what to look for when breaking it down and any mods when building welcome.

If you know your way around the air cooled 430 then you wont find too many differences, the 88 had the larger 6 bolt clutch set up but thats pretty much the only major difference. Watch out for the usual mag rot behind the pump cover and of course being watercooled there is a head gasket to contend with. You can lift off the barrel and head without disturbing the gasket and if it doesn't need a rebore then you will have saved yourself quite a few quid. Andy at HVA-Factory has most items you are likely to need in the way of spares. The 430's came with both 4 speed (MX) and six speed (XC), very few 430's in the UK were enduro's but not sure about Spain, I still have Geraint Jones's 430 barrel and pipe from his last days of Swedish Husky racing and intend to put a motor together one day and use it. Good strong motors and much nicer than the 500's to ride as they don't vibrate as much.

Enjoy!

basic design as the air cooled
the clutch and shaft were upgrade in 87 and 88 to a six spring and the clutch bolts on
most were 6 speed except if they even had a CR they were 5 speeds
they are pretty bullet proof, cheap power is to knife port the transfers
the clutch cover should be aluminum on this year and did not have the bad rot issue of the 84-86 with that said if it was run and stored with only tap water you could see a problem
the ignition was typical Motoplat
pull the top and see what you got, post pics of the tear down

WTF do you think your doi ng.... heh? I thought you were finished with projects??? you were not supposed to get a new one till the old one was sold....(footstamp)

as to the advice and tips,

The kickstart piece that attaches to that clutch cover has less offset than 86 and prior. Just judging from the condition of that little rubber piece it looks to be less used than stuff I generally aquire.

The six spring clutch makes more stress on the rotating shaft the cable actuates and it's bore could be sleeved with bearing bronze in my opinion. It seems there was a bushing added to the bottom of that shaft in the older single cam section though yours may be still fine cr probably didn't go as far and in as much mud as wr.

Look at the surface the little needle bearings ride on in the starting gears, one of them I think the one with the ratchet stuff seems to have had poor or no heat treatment.

As to in general the differences between an air cooled 430 and an 1988 model I don't feel like typing that much. The minus is they omitted the plate near the chain sprocket so there is no way to sneak out that bearing and it is generally the first thing to go bad and if changed in preventative mode maybe the unit could be used until the crank fails.

The clutch cover is improved with sleeves that are magnetic at shifter and kick starter shaft, the additional bolt as well.

The intermediate shaft attaches to the drive side case in a more robust fashion, the starting gears are a bit different and not interchangable. The crankshaft is more I beam like than popsickle stick on the connecting rod and the small end has scalloped cut outs which may or may not be better. I think a slit is most common in modern stuff. Of course the hole in the rear is two mm larger.

Thanks for all the info, this site rules Cleaned the thing up today and a little inspection. It's a 4 speed which isn't great for me as it would probably end up in a road bike. My 6 speed 430 really hauls ass ! I only fairly recently discovered it's true potential, ran it in carefully then one day just held it open over the flat spot and ye ha we were off. I think it's peaky cos of the pipe but should dyno next week with luck. Any one who rides one of those off road must be barmy, it must do 90!
Not sure what to do with this, mr Surprize is right, I still have another major project on the go at the moment.
The piston looks ok though, soaking the head nuts in WD40 overnight so will lift the barrel tomorrow. All gears select and it does have the Ally clutch case not magnesium.



The impeller looks modified?




The small end bearing is floating side to side. After market piston? I spaced my A/C but I know they do run like this.



And a standard mini 6

I will try and make a few comments to post #6 above.

I really think 5 speed is what it shows in the parts sheets for something like that. It might be possible to change enough stuff including the clutch to use an earlier four speed or perhaps a later one from the next section on here. Wander around the parts sheets yourself and see if I recall correctly.

The impeller has drifted out and worn itself against the water pump housing. I do not see a snap ring to hold it in place but even with the snap ring that sort of wear is kind of common and why I change out the bearings lately. That is more extreme than anything in my collection. The cost of the impeller a new housing and the shaft make new left over whole motorcycles appealing. I think without the shaft about twice the cost of a rebuilt waterpump for a pickup or van.

The replacement needle bearings for both the 430 and 500 seem to have been a little shorter than the origionals, never ordered for any other models. The rollers/needles are still within the rod edges and you can see the scalloped feature I mentioned in a post above. You have to dis assemble more before I can tell if it is an origional or genuine husky replacement one.

Whether one really needs more than 250cc at sea level could be up for discussion. You do get 10 pound flywheels and for the 88 the clutch basket is steel for even more rotating mass.

 

[2premo]

Frank is right about the water pump I always replace the bearings seal and impeller clip
my 87 250 has aluminum spacers to hold the small end bearing centered might be a 250 bearing
and a 250 at sea level is pretty impressive, but I ride at 6000 to 9000 ft

 

[Wildebeest90210]

All the bearings seem good, some very minor water damage. A mahle piston that looks good and no bad scrapes in the bore. The little end does float about but can't be spaced as the piston casting doesn't allow it but then, if it ain't broke don't fix it, comes in to play. Still can't find any more than four speeds though.
As you can see on the vintage for sale thread there is a guy selling frames and rollers from the 70's not far from me. I could just go and look? A LC in a red bike?

 

[suprize]

Nice project, put it in a go cart!!

 

[fran...k.]

I don't know if my depth perception is off but that head picture looks like the squish is different than these wr and ae (all 430) heads in the picture I attach.

On those pistons what I suggest looking for is to see if the pin has elongated the bore in the piston itself. Yours looks pretty new but I only have, been able/chosen to, re use one of those from an automatic bike because the wristpin in my opinion is too short.

I kind of doubt the rod will drift to one side in an assembled and running engine, can't recall seeing scuff marks to indicate that, yes the needle bearing can wander side to side.

Cylinder studs all came out of the case by turning the head nuts or removed later?

 

[2premo]

while I was scrolling down the head squish caught my eye too, possibly a reconfigured squish someone thought might make more sense but not sure
also if the head does not have 430 tool stamped on top then maybe someone modified a 400 head to fit
on the wristpin bearing, my 87 CR250 piston looks similar in that the inside is not machined any different than yours and has spacers to hold the bearing centered, the rod is the same, most likely different wristpin as they come with the piston, the bearing can be had separately but is different, I have a bunch of 430 pistons laying around need to look at that as I never really paid attention,
what do the transfer ports look like from the bottom on the cylinder?

 

[oldbikedude]

Beast, you know I like the LC430! I had a 87 cr430 that was a four speed conversion. The guy I bought it from said the husky shop told him they could repair his 5 speed cheaper if they leave out a gear & make it a four speed. I think it was fifth gear because there was no change in first. Not sure at the moment what all must be done to do that....shouldn't be to hard to figure out though.

 

[Wildebeest90210]

The clutch slips a little the man said. Hmmm, I don't think it ever even pulled away like this. I'll let you follow the pictures, you can see from the case wear on the inside it was running when the little accident happened. The oil is full of ally too. I guess this was behind the descision to break the bike. Still I don't mind, the price was OK.
And, I have a cunning plan.... I don't have the time/money/space for this right now but there is a badly advertised '96 te350 as seen below that ends tomorrow. The clutch I reckon is identical as may be the gearbox etc etc and the 430 motor should bolt straight in ****************************************!!
But, this would be my second Husky, I know how these things start, I'm going to drink some beers now while I've still got more beers than Huskys.
And, I got to decide my limit for bidding on the 350 tomorrow, any thoughts???

Chances are someone has switched in some earlier transmission and clutch components. I am not familiar with european spec stuff, The 87-88 clutch dosn't use the snap ring I can just barely see in one of the pictures you posted. I also noticed the parts sheets didn't get the increase to 6 clutch springs for the 87-88.

Ah yes, just counted, 5 springs! It was the other way around on my 82 430, came with a 6 spring.

No you buy it then you can tell me what I have to do when I try to transplant an Auto engine into a modern chassis

the clutch looks like an early 250 by the looks of the gear reduction, it should have a 6 spring and you will not be able to bolt a 350 clutch straight in, first off the cases need to be split to change the shafts to the newer style, not sure the clutches are exactly the same but the 4 stroke was based on the 2 stroke bottom

if you were hoping to bolt the 430 engine into the 350 chassis it is not that simple been there done that
the front tube on the 350 is a single with twin exhaust and the 430 has a center exhaust that has a twin tube for the exhaust to go through, they don't use the same radiators but you could overcome that with different hoses, the intake on the 350 is high due to the carb feeding the head and the 430 is low due to the carb feeding the barrel, but it will bolt in

so different front tube, different hoses and home built air box connector, aluminum airbox adapter is easiest

the parts breakouts are nice but take them as a drawing that was not always updated, the 88 still shows a bearing cover behind the sprocket
