Need help with 63 model 2000 series

[WV8N]

The only tractor I have ever worked on much is an 8n. I needed brakes and an oil seal on this 2000 I have.
I picked up grease seals, new shoes and a repair manual. Obvioulsly this set up is completly different from a 8N. I have pulled the axle assembly with backing plate ect. Like I said I ask supplier for grease seals but I need oil seals.
I was going to go ahead and replace grease seals since I have them but according to manual this seems to be a major job that I dont need to do.

I am trying to figure out how to get the bearing axle assembly apart. The way the book explains it it seems to be a major job. Talks about drilling holes and chiseling the lock ring.
I guess i should check the bearing since it could be bad and caused the seal failure. but on the other hand if it not broke why fix it.

Another question is what lubricates the axle bearing since the oil seals are suppose to keep that part dry. Is it a sealed bearing? can anyone offer any suggestions

Any help greatly appreciated

Thanks
Patrick

Patrick:

The inner seal is the oil seal. This seal can be changed now that you have the axle assembly out.

The outer seal is the grease seal. This seal cannot be changed unless you crack the shrink-fit collar and remove the bearing so as to remove the axle from the bearing collar.

The bad news is you cannot properly pack the bearing without removing it and it, no doubt, needs packing.

The rest of the bad news is: If the inner oil seal has been leaking (If there is oil on the brakes, it has been leaking.) oil has entered the bearing cavity, no doubt, washing any remaining grease from the bearing. Further, oil remaining in the cavity will leak out past the outer grease seal (new or otherwise) and onto the new brake shoes. The design of the outer grease seal is intended only to prevent grease (not oil) from getting onto the brakes.

The bearing is not sealed. It is lubricated only from the grease with which it is pack. Most likely, it has not been repacked since new.

So I need to crack the collar and then bearing will come out? Does it have to be pressed.
So I guess if the bearing is ok. I just need to replace the shrink collar.

I take it this thing is brittle and will crack fairly easy

When you drill it first as they say it will crack easily. New collar is not expensive from CNH. Inspect the bearings/races closely since as Dean suggests they along with the grease in them have likely never been serviced since new.
You will find that tractor not much harder than an N to work on but much superior to an N for working with.

I"d also question why the seals leaked in the first place. Just did this same job on my 2000 gasser and found the axles were bent just enough to cause the seals to fail soaking the brakes and making them fail. While it"s all apart check the axles. A good machine shop can bend them back for $40 each.
