I picked mine up from the docks 18 months ago, tracks chocked front and rear, ratchet straps on the pintle hook and crisscrossed on the idler wheels and drive wheels and finally the winch cable around the idler wheel arms….didn’t budge an inch!

@OZM29C thanks very much

@Beepbeep Your sprocket teeth look decidedly worn. I have got a drawing somewhere at home that shows the correct tooth profile but as a comparison, attached is a photo of my LAR sprockets and you can see the difference in the teeth when compared to yours. Unfortunately LAR don't make this sprocket any more.
@OZM29C did you find the original tooth profile? I'm thinking of getting my old sprockets repaired and it would be good to know what profile I'm aiming for

I took another 12 grousers apart...35 to go....8 x 55 holes to drill....X 2...so 880 holes plus bolts, washers and nuts.....
Oh wow! I don't envy you that job

I could have done the same thing with the original sprockets and saved myself $800 and a bunch of time drilling out rivets!
My thoughts exactly!
An update, my sprockets have worked out a little more costly to be hardened than I thought due to the way they price these jobs. They're priced on weight so you pay to treat the whole piece but I didn't want the rear faces hardened in case they damage the track guides so there was an extra charge added for coating the areas you don't want hardened! It wasn't very much though and the four of them have still come in under £140 so not too bad.

They should - mine are wearing badly!
@Patrick Tipton That's really bad and from what I've learned now there's no excuse for it. I went to two local hard facing companies and they both told me that the factory spec really isn't very hard and that there's steel plate available that has a compatible hardness, think it might have been EN31 but I'm not sure. I checked Accu-Rite's listing and our sprockets are made from hot rolled mild steel and when I checked it has a hardness rating half of the factory spec! I was also told that there are welding rods available with various hardness ratings so in theory it may be possible to repair the sprocket teeth. Weasel ownership really is a learning curve isn't it?

Well I've solved my problem, I hope! I couldn't find anyone that flame hardens but I found a local company that will carburise the sprockets to the hardness that I want and at a very reasonable price, so reasonable that I wonder why the manufacturer doesn't harden them as standard.

The track drive lugs are hardened to Brinell hardness 534-601, so about twice as hard as the drive sprocket teeth.
Wow, that’s interesting! Thank you for that

Hello. Hardening is not the best solution - the gears cannot be too hard because then the tracks will wear out and they are more difficult to repair. I have to have a proper hardness check of the gears and track plates to choose the right hardness of the new gears
Yes, I read that recently, that the teeth should be hardened but to a lower level than the grousers. Procedure as follows - ‘Flame harden contact surfaces of teeth 1/16” deep to Shore Hardness 70 minimum. Heat to 843 degrees Celsius - quench in oil - draw to Brinnel Hardness 241-269/Rockwell Hardness C 24-27. Hope this makes sense and that it helps. It doesn’t mean much to me but I’m going to go to my local machine shop and see what they say

Hi Tomek, thanks for your post. I bought the sprockets on eBay but haven't fitted them yet. I've got to say yours look really worn for having only done 200 km, I asked a local machine shop about hardening when I bought them and they advised against it, guess I'll go back and see them 😞

I don't think he will ship to the US - at least that is what I have heard. Anyone have a set?
No he doesn't ship, I forgot to mention that. I know someone here in the UK that has a set but he had to go over to the Netherlands to collect

@Dake20 yes they are available from Oscar Wennink in the Netherlands, you'll find him on Facebook

It's a standard Junior Military filter, a Mann PF1155 is a modern day equivalent. I've got a Baldwin in the workshop that you might find easier to get but I can't remember the number, I'll take a look tomorrow

@Patrick Tipton let us know how you get on, I’ve just split the wheels from the old sprockets so a little way behind you

Does anyone have a web address or phone number for Accu-rite machine in California? I looked on the internet and can't find what looks right for them.
Mark
Hi Mark, they don’t appear to have a website, phone number is 559-292-6933. I bought my sprockets from them through eBay

Mine's called The Weedsel as, for some inexplicable reason, it stinks of weed!!

@BeepbeepNOS😄
Ah you lucky man! could you tell me what thickness the rubber is? I haven't been able to find that info anywhere
-
@OZM29C thanks for that, very helpful. One last question, your wheel looks as though it's been re-rubbered, something else I need to get done. Did you do it yourself or farm it out and what thickness rubber is it?

@OZM29C I see you've bolted your sprockets and drive wheels, did you use countersunk socket head screws on the sprocket side?

Please let us know how the sprockets are from Accu-rite Machine works in California.
Good Luck
Later 42rocker
Will do rocker, they’re off to a good start I was messaged yesterday to say the sprockets will be shipped this week!

Seeing those shows just how worn my sprockets are, thanks for that. I’ve ordered a set from Accu-rite Machine works in California so hopefully that’ll be the first step in rectifying my problem. Thanks again

@Beepbeep Checked my NOS seat bases last night and I can indeed confirm that there is a wedge shape in the seat base. Highest at the front. Drops roughly 30mm from front to back. Cheers
Thanks very much, I’ve got Norwegian bases in my Weasel which are about 30mm lower at the back and I just wanted to confirm that was correct before recovering them. Thanks again

To answer a couple of your other questions, there are latches to secure the windshield to the brush guard. Regarding loading as you can see I loaded mine on forwards, the bulkhead of the Weasel is it's centre point so I loaded mine with the centre point just forward of the centre axle of the trailer so the weight was biased toward the hitch
