Hey all- new here and just bought a "rescue Husky!"

Howdy from Texas! Thank you, administrator for running this site! I was in Iowa this past weekend and browsing Craigslist, when on nearly the last page I came across an "83 WR 400." The guy I bought it from in Spencer, Iowa said it was an '83. Turns out it was a 1984 WR 400 LC. It wasn't running, and he said he didn't get a chance to look at it but that the top end was seized. He wanted 650 I offered 400, and went up to 500.00. We settled on 500.00, and took it back to Texas. Took the top end off, and the lower end bearing and rod was fried! Top end was not seized but piston is cracked. My issue is now I need a crank...not sure if the connecting rod is the only thing damaged, but I hope the crank halves weren't damaged since Husky doesn't use thrust washers on the lower bearing. Piston says 82 42 on it, and wondering if it is a standard bore?? I need to get the manuals and start measuring clearances. So I will be posting on the progress (it will be slow) and hopefully I can find a crank out there! Just the few repairs I have to do will bring me int the 1800 range, just to get it running. Took a gamble, and oh well. The forks are not white and springs yellow.... Is this factory? It's a Husqvarna 1 WO 17438 and engine is a 09820109. Any help would be much appreciated.

Sorry for the multiple pics!

arrrrgh !!

I have a number of Husky manuals that I've collected in PDF format. I do have the 1984 WR400 parts manual, not sure whether I have the service manual, but I'll check this evening after work. I can upload the manuals so that you'll be able to download them if that helps you with the project.

welcome to the site!
if you are handy at all, i would consider purchasing the few tools needed and doing the labor on the engine yourself. it will save quite abit of money and many here can walk you thru it. of course you will need to still have a shop do crank work and work to your jug. do a search on here, we have talked about the splitter and installer to do the job. there are a few choices. these are pretty simple well made engines, but you will have to get it split down to inspect everything.
great bike tho, the 400 is a good motor and that chassis will handle well. the forks likely have the paint removed. the rear springs may be new or original ohlins springs, as these have ohlins shocks factory.
bike looks pretty good aside from the engine issue

Thanks for the info gents! If you have the time, I would really appreciate the PDF Manuals, Steve! I grew up riding dirt bikes, and remember when the '84 Huskys came out. Dirt Bike magazine was my mag of choice on the "terlet." I have been turning wrenches since I was a kid, go I have an awesome set of tools. (just no room to wrench!) So I will be splitting the cases when I get time,clear out the junk, and see what I got in the engine. Husky John, If the crank is in good shape, and trued, I am definitely interested. Shoot me a price an d a number, when you get time. I am trying to find out what direction I am going to go on this project. I might strip and powder coat the frame, but don't know the paint code for the white. The ITC shocks look like this dude painted the blue anodizing at top but didn't do the piggy back reserviors. I want to powder coat the forks the original Husky White also. I pulled the carb, and seperated it from the airbox only to have straw, junk and mouse crap come out! make matters worse, the venturi throat picked up some corrosion from the mouse urine, I will put it in Berryman's carb dunk for a couple of hours. Rest of carb looks great, and looks like I have to do a little welding on the expansion chamber due to vibration. Anyway, I will be on a rapid learining curve as this is my first european bike. So thank you all, again, for your help and input. Much appreciated!

I do not have the service manual for your bike, but I have uploaded the parts manual to OneDrive. You can download a copy at this link. You'll need both parts manuals in the folder for your machine. Anyone else on Café Husky wanting a copy is welcome to download.

Welcome mate,
As you can already see there's some top guys here, very helpful so you should be able to do the majority of the repair work yourself to keep costs down. aside from the engine it looks pretty good, good luck with getting it running!

just look in the vintage tech refs here for part manuals etc. phillip at Husqvarnaparts.com has all you need to rebuild it. check his web site. check the waterpump housing isn't toast. great bike and you have the better yellow springs. get to it!

What ever you do don't cut the rear frame loop off to make it look like a CR.
The 84/400 Lc's are a bit rare and don't deserve being chopped up.

We have the correct Con-rods / pistons / gaskets etc on the shelf. Pistons all the way from 82.5 up to 88 mm diameter - which would then make it into a 430!

Try http://www.mrcrankshaft.com/ for your crankshaft needs. I've used them more than a few times and their work is always excellent.

82.5 looks like the standard bore where I looked it up with the piston size you quoted sized to fit in there. I didn't notice anyone answering that.
It is the same crankshaft as a 430. I think they go for about $100 for a used one. If the crank really wore out with proper maintenance, fuel mix etc there is probably a lot of stuff inside there that is worn out. The chassis doesn't look that way in the pictures, is the paint original near the foot pegs, the amount wore off?

Kind of a tough call buy three more in similar condition at that price or fix what you have identified so far. The dual leading shore front brake and wheel and the two shock absorbers should be worth half or more of that $500.

Looks a great buy for $500. Good luck with the rebuild

I am going to split the case and pull the crankshaft out. Check main bearings and seals and judging by the lower crank either it was under premixed no premix or just plain failed. The piston and ring wasn't siezed, as well the crank moves freely

they suffered from "oops, forgot the oil" syndrome a bit these bikes, usually with the 2nd owner....

Especially in this 'new' 4 stroke age we live in.

ol mate picked up a 400 in the 1990's to do up. it was being ridden to work by this bloke in Melbourne and it had "stalled at the lights " and when he went to start it, the kicker "jammed".

that translated to it was locked up totally from no oil in the fuel.

We found a good lower end, a barrel and a few new bits and pieces and he was away!
