1972 Argo 8x8

[Tremmorkeep]

Does anyone know the chain size for the drive chains? I pretty much need new chains all around and I'd like to buy in bulk if I can.

I'm told Fastenal has lots of chain but I gotta figure out what to buy.

all chains ar single strand 60 weight and the idlerlers have 40-2 or 50-2 i think.

Your machine should have single 50 drive chains to axles and either single or double 40 chain off trans to jackshaft.

I have a 79 T-Base Argo 6x6. I used single RC50 for the drive chains for the axle and double 40 (40-2) chain for the trans. I used diamond brand chain for the trans (ebay) and some heavy duty chain from a tractor supply store for the drive chain. (I think it was tsubaki brand)

Sweet, thank you all very much for the information. I have a Fastenal close by (2, actually) and tractor stores...are like IFA and Cal-Ranch...I'll see what they carry. The chains in mine are so rusted that they dont even bend....even a little...

time to get the grinder out

[Tremmorkeep]

Yep, gotta chop them out...I cant even test the bearings and seals because the whole dang thing is locked up...heck.there's one wheel that won't even come off....LOL. Its going to be a project for sure.

Chains and Trans oil

Did you end up confirming the chain sizes on your 1972 argo? I have a 1972 6x6 that I am currently trying to bring back to life. I would like to replace my chains as well. I have a kohler K3992ST any chance you have the same engine? Also I wanted to replace the trans oil I see in a manual i found online it says to use SAE 90/140 but the closest I have found so far is SAE 85/140 anyone have any input on that?
