Did International forget rear axle grease fitting?

I"ve been using an International 484 for about 13 years baling and moving hay. This summer the left rear axle had an occasional squeak and finally last month the squeak changed to a constant grind. I"ve removed the left axle carrier and axle and the outer bearing came out in pieces. I"ve cleaned it out but can find no way to grease that bearing other than to dismantle the rear of the tractor. The local dealer claims there should be a grease fitting but I can"t find one and can"t see where one should have been installed.

Do they make a grease that lasts for another 30 years that I can pack in and forget about? Or is it possible to snake a very thin grease gun in around the outer seal? Or should I tap in a grease fitting?
Thanks for any advice you all may have.
 
I am not familiar with the 484 model but on H thru M series there was a grease fitting that was on the outer part of the axle housing that often got broken off. maybe check out your axle bearing retaining cap and see if there is a spot that may have once contained a grease fitting.
 
Hi, the last tractor that we owned that I remember having an outer axle bearing grease fitting was 300U build in 1957/58. The B414 we purchased in 1962 never had one and also 454 (similar to 484)purchased in 1972 and still running strong. I am not sure but I thought a small amount of Hytran from transmission/rear end was supposed to lube that bearing. Looked at CaseIH parts on line and there is an inner and outer oil seal on the rear axle, so is inconclusive as to the presence of Hytran to that outer bearing. Maybe someone else will give us the correct answer.

IH seemed to eliminate that grease fitting on the 5-speed rear-ends by the time the 60 series came out. I can see the pad on the retainer where the fitting ought to be. Keep the trans fluid up to the level plug.

Yeah, the rear end lube comes out if the seals are going bad, so some HAS to be getting to the bearing.

I thought that the grease fitting on the axle caps was to keep the seal lubed and sealing?
 
Thanks for the replies.

But the Hy-Tran doesn't leak past the inner seal. The inner seal is the kind with a thin rubber-coated spring wound around the axle and no fluid gets past it. The axle and housing between the inner seal and the outer bearing was dry. It's been dry for quite a while and I've been keeping the transmission full.

There is no bearing cap. On the axle from the outside in is the wheel hub, an oil seal and the bearing and that sits against the bearing cup. Then there is about 18 inches of axle until the inner seal.

The local dealer service manager insisted that the axle should be dry and there should be a grease fitting on the end of the carrier. There is no fitting and no obvious place to put one.
Would the International Service Manual have instructions on keeping this bearing greased?

Thanks again.
 
Never been into the back of an 84. On my SM when the axles started leaking too bad I pumped grease into that plug.
 
The grease fittings on the letter tractors was there to keep the dust/dirt shield (felt washer) lubed -ONLY. The outer bearing is lubed by the main frame oil which is kept inside by the outer oil seal which is inboard of the felt washer. Don't have any knowledge of the tractor in question. ...Randy
 
The owner's manual from CaseIH will tell you every single grease point. Where is this inner axle seal? On the bearing? Outboard of the bearing? I'd be looking closely at the IPL on the CaseIH website to see what it reveals.

My 584 doesn"t have a grease fitting for that bearing. The service manual states to "pack the inner & outer bearing cones with multi-purpose grease." There is also quite a procedure to install the axle into the axle carrier.
