WC lower final weep hole?

Gentlemen,

I have a 47 WC that i can't seem to keep gear oil in my rear axle. There seems to be a weephole at the bottom of the brake housing that's become more of a firehose.

Anyone know what purpose it serves, and how i can get it to stop lubricating my tires?

Here's a pic of my tractor... it's more like a rolling tetanus death trap at this point in time... ol' farmer john made it so before i bought it.

Thanks!
 
Your weep hole is more than likely an access hole to get at the brake drum lock screw. That is what it is on B's and C's anyway. The oil is probly coming from around the seal at the transmission where the final drive bolts fast.
 
That weep hole is to keep the inner Axle seal that is leaking on your tractor from filling up the housing and getting oil on the brakes. Plug it up
and you will shortly no longer have brakes on that side.
 
The weep hole is to ensure the brake housing does not fill up with rain water, if there is oil then your seals need replacing, I had the same problem a few months back
 
That arrow points to what looks like a pad for bolting on some part of an implement. Possibly the hole was drilled too deep or the casting had a small imperfection there
and it is leaking. The oil level should be above that I would put a bolt in it with a copper washer or other seal under the head to stop it and check the oil level. Oh,
you probably know that picture is of a steel, WW2 era rear end, somewhat rare. But the final drives are the same I think.

I have a '47. The whole thing is steel, except the block.

What you posted is what ticks me off about the antique tractor community across the web in general - no hate directed at you. While i certainly appreciate you being helpful, your post is speculative. These holes are in the same position on both sides, and both are thru holes. Seeing the other work that was done on the tractor, these holes are straight and not wallowed out, as most of the other work done by ol' Farmer John is fabri-cobbled at best. This makes me speculate heavily that the holes are factory original.

Additionally, one of the posters above stated that they are to let water out - which i have a slightly hard time believing since there are no top holes or crevices that would allow water ingress. His other part of the post, however, makes complete sense - I have a inner seal that is pretty close to non-existent at this point.

NOW... the question that remains... Where do i find axle seals for a somewhat rare '47 WC rear? I haven't taken it apart yet; will i get luck and find it's all cork paper seals?
 

I already have no brakes on that side despite it not being plugged.

Interestingly, the side that's full of solidified oil (and plugging the hole) have brakes that work great.
 

If you could point me in the right direction to fix it, it would be very much appreciated.
 
You need inner oil seals( AGCO part #70217873) on the axle . The AGCO parts book shows the assembly and lists this part number for Tractor numbers ending with S.
 
(quoted from post at 12:44:05 02/28/17) That hole is a weep hole and there should be nothing in there but dust from your brakes wearing.

That's what i figured.

Thanks for pointing me at AGCO. They seem to be a pain to order from, and it doesn't seem the i can order from a independent servicer for allis parts. Maybe i'm missing something.

Thanks, big help. I'll give them a call.

One more question that perhaps you know-
My WC has a PTO drive attached, and that's it. I don't seem to have a intermediate shaft from it to the rear of that tractor( not like there's enough space anyhow ). How was this configuration used to drive implements? Seems like a awful long driveshaft to have on something direct from the PTO to the drive without some kind of fixed intermediate.

My google fu is letting me down here, and despite claims that the WC was the most common tractor AC made, all I find is info on the WD which has a totally different rear configuration, as you know.
 
The bearing on the rear end of the pto shaft bolts to the rear platform. You mention no space for a pto...I assume your drawbar is straight, and where it bolts to the underside of the rear housing, is where the pto needs to go through. The drawbar for a pto-equipped tractor has a "C" shape to it on the forward end, allowing the shaft to go through.

WC production was something like 170,000, while the WD and WD45 were over a quarter million.
 
Here's some pictures of what the underside of my rear looks like(that sounds strange!):
