Drive train slips

[som1335]

Only had my 89 argo 8x8 for a few months. All worked fine until recently. goes great in forward or reverse, but when I put a load on such as hard brake steering, backing up a hill from a dead stop, etc, something is slipping. Looking at the drive train while applying power it seems the differential is slipping under load. sounds like a chain skipping a sprocket, but that's only what it sounds like, its not what's happening. As a mechanical dummy it LOOKS like it is the shafts that come out of the transmission housing that aren't spinning properly. Back yard diagnosis anyone? Time to part out? (18 HP Kohler)

I don't know how the driven pulley is attached to the transmission but I am wondering if a key is missing there.

post up pictures or a video.

It could be the trans. diff. or simply loose chains jumping, broken keys in the drive disc or various other issues. A small video of what it is doing with the firewall off, crap it's an 89, through the hood can tell us all many things( or guesses at least ).

OK, I took a better look and the chains are not jumping, where the drive shafts come out of the transmission the shaft chatters under load Is there a key or pin there or is this 89 just a piece of sh*t. Can't post a video as the left front axle shaft has come out of the inner bearing. I don't know how to make the shaft stay where it belongs. I put a new grease seal in and I guess I put it back together wrong.

You might have the bearing carriers backwards

[curtisbyrne]

Make sure the inner bearing has a bearing carrier on insidea of it so I stops the bearing from slipping out.also check if all two set screws are in each bearing!

[ARGOJIM]

Again, it could be something simple like a broken drive disc keys or the differential could have broken gears in it. You may have a broken teeth on one of the jackshafts due to worn chains. Your description is somewhat common yet they are all vague.
Where are you located?

It is possible your issue is external of the transmission, though the worst may have happened.

Thanks to all. I'm in Maine BTW

[som1335]

OK, now I kow i'm missing parts. No such thing ther as a bearing carrier on the outer bearing. Maine

I think I am having the same problem,I back up a little incline and one slide moves and the other don't and its vice versa,what is the causes of this,I also don't have the front chains on either
