What tool or device do you use to remove and reinstall the RA inner oil seal in a 8N? I haven't pulled the axle yet and wanted to get an idea before I did same.

Thanks

Paul

The inner axle oil seal is pressed into the trumpet housing. It can be removed after the axle is removed with a big long screw driver or better by using a sharpened nail set to drive a small hole in the metal part of the seal and then screw a sheet metal screw into this hole so you can get a hold on it with a pair of vice grips or a wrecking bar nail puller end etc.

Your inner oil seal, 8N4233A, is a cylindrical cork gasket that fits over the axle shaft before your bearing retainer is fitted to the axle. This is for 1950+ models. If you haven't been there, I suggest you go to John Smith's excellent article on the subject. I have some addenda to John's article, email me if you are interested. Good Luck.

Sorry to have to disagree,but you are speaking of the 8n 4284.The 8n4233 can usually be removed with a big screw driver or pry bar if you don't have a puller. don b

Absolutely right Don. The inner seal 4233 was a pain to get out with a hack saw blade in two places. This is before I got the two jawed gear puller. It made me real nervous getting that close to the mating surface.

I pried and pried on that thing! I finally cut it, in two places 1/2" apart, with a cold chisel and lifted it out with a screw driver. That metal is soft and it cuts real easy and I was carefull not to score the trumpet at all.

I ended up using a cold chisel and a hammer and cut it and then pried it out. It was like most other oil seals. Since I had never taken one of these out before I was a little concerned about what was behind it.

How much should the hub extend out in front of the splines? Put new hubs on and I was evaluating the axle condition. The very small machining or forging marks are still visible on the axle splines and no bright spots.Don't think there is any wear on the axle.Seems like a tight fit now between hub and axle.

One of our local parts guys tells me that before and after a certain serial number 8N's no longer had an inner seal. My tractor's serial number is 483709. I don't remember exactly where the break was in serial numbers but it was below my serial number. Does anyone know anything about this? Thanks in advance for any info you can provide.

That sounds just like what I saw with the machining marks and all. I didn't measure the hub overhang but it might have been as much as 1/4". There were several 'virgin' threads on the axle.
Get plenty of torque on there. I think you need to make a fairly serious effort on the end of a 4' handle to get 450ft/lbs. My 18" torque wrench requires a sincere effort to get 150ft/lbs and my 24" torque wrench demands two hands, two firmly planted feet, and a grunt to get 250ft/lbs.
Figure from there is seems like it might be more then you want to do on the end of a 3' handle to get 450.
The guy at this link claims you can get 1,000ft/lbs with a 6' cheater on a lug wrench.
