8N front wheel hub bearings inspection/greasing.

Hello,
well on another post of mine I asked about getting the bolts out of the front hub. Since it looks like I will have to press them out, since I'm removing the hub, seems like it would make sense to inspect the inner and outer bearings.
I did not pull it off yet as I like to understand as best as possible what I'm getting into before doing the work. The F04 on page 11 talks about driving out the inner bearing. Do I need a special tool for this? Do I do it through or from the front/outer end of the hub?
The F04 did not seem clear on the outer bearing. Does this just lay in the hub or do I need to push it out to clean and regrease?
thanks
 
I just came across your post and see that no one answered you. When you remove the nut and washer, just pull the wheel out a little bit and then push it back in. The outer bearing will usually just fall out. As for the inner bearing, I lay the wheel or just the hub, if that's what you have, down with a rag under it. I use a socket about an inch or maybe 1 1/16 on the end of a 12 inch extension. I place the edge of the socket against the outer edge of the inner bearing and drive it and the seal out with a hammer. Another old method, is after you remove the outer bearing, put the washer and nut back on the spindle and pull the wheel out and let it drop a little until you feel the inner bearing catch the washer, the jerk the wheel off. The bearing and seal will remain on the spindle.
 
Thanks Jim for taking the time to respond. Much appreciated. Is the dust seal by that inner bearing a salvageable item or should it be automatically replaced? thanks again.
 
I would replace it. They aren't expensive. I don't see it in the FO-4 manual, but in the service manual for the 9N/2N manual, it says that the rubber portion of the seal should be facing the center of the tractor. Same for the 8N.
 


This site sells new seals . They also sell Part No: 957E1139 for a Ford 3000 and others , hub cap with a grease zerk . You can not see it from there picture , but the grease fitting is protected by the square nut face of the cap , so it will not get knocked off by driving too close to an object . On my work tractors I pump them full of grease and often when checking the tractor before use of the day . There are no brakes to foul with too much grease . You might not want use them for a show tractor .

I am so sorry if used "there picture " when I should have used "their picture " . You would think that three years in the fifth grade would have taught me better . They're I feel better now 8)
 
Thanks Ken. I have a local Ford dealer, well 20 miles, that has service me for many years, so for now, I still go to them.

oh, now I get it - went to 5th grade too for three years- that picture of the cap is probably interchangeable with my 8N. When I tear it down tomorrow, I'll see how much grease is in there. I do have a fitting in the vertical spindle/shaft so assumed that takes care of the grease. But maybe something to consider down the road. thanks for sharing.
 
Teacher's pet! or is it Teachers' pet?
Okay, waited till today when I had hoped to tear down the front wheels. I did tear them down and this is what I found, so a few more questions for the forum. It is fun and intimidating the first time trying things.
I made an observation about the hubs themselves that maybe I have a 2N, which was a post of mine a few days back about the emblem on my, otherwise, 8N tractor.
LEFT wheel. Outer bearing came out just fine. Tried the trick method but that did not work or I did not do it correctly. Got my inch socket and gave a few whacks. Had to give it a few more harder whacks, but then it dropped out. thanks. As it dropped out, the dust seal came out too which I forgot about. Bearings still looked good.
Outer bearing is Bower - 09074: Inner is Bower 15118 and the seal is Trostel 16336. After cleaned the seal off, then I saw it is a hard rubber probably embedded in metal.
RIGHT wheel: Outside bearing came out like the other side. Did not even try the trick as I was expecting to whack this one out too. But staring at me more noticeable than the other side was the dust seal. This was one was pliable rubber. I played around with it a lot but then found that it had a metal backing. Using a small screwdriver, not sure if this was dumb or not, I could pry or pop it up a bit. I but about a 1/4 wood shim I made under than spot, protected the rubber there and was able to pry up the other side. Then, to my surprise, the bearing fell out. So now I was worrying. But the bearing looks really good. But as I was cleaning the inside a bit, what I think is called a cup that the bearing rides against, was turning; after a little bit, it came out. So then I wondered about the other side. It does not spin and I did not push it out.
It was fun for me to see the part number on the seal.
Seal: FoMoCo part no. 2264739. ORCOTIPE (I think I got all the letters correct) mfg by The Ohio Rubber Co NCA 1190 - A. Fun since I worked for BFGoodrich in Akron for 10 years, but this company, closed in 1991, was an east side of Cleveland suburb.
Inner bearing: Bower 15118 (same as other side)
Inner cup: Timken 1520x
Outer bearing: Timken 09074 (different company but same number as Bower.
Some pics attached.
QUESTIONS:
Is it okay that the cup came out on the right wheel, by inner bearing?
Is it okay that neither of the outer cups came out.
Could the Ford Motor Co. seal on the right side by an original?
The bearing probably have been replace as they don't match my FO-4 but are they 8N parts vs 2N parts or are these bearings interchangeable.
The seal on the left side must be a replacement since it is different than the other side, but are the new seals hard rubber rather than soft. I ordered replacement seals anyway, but that rubber one still seems good.
Lastly, does anyone know what those ORCOTIPE, letters stand for on the seal?
The pictures are left side first. I know on the second picture that the rubber was against the spindle, but my first picture, now I 'm not sure if that metal was against the spindle or the hard rubber was.

[b:afa94ae7c5][i:afa94ae7c5]Is it okay that the cup came out on the right wheel, by inner bearing?[/i:afa94ae7c5][/b:afa94ae7c5] No, the cup should be a slight interference fit to prevent it from spinning on the spindle rather than spin the roller bearing. I've had good success with Loctite Bearing Mount.

[b:afa94ae7c5][i:afa94ae7c5]Is it okay that neither of the outer cups came out.[/i:afa94ae7c5][/b:afa94ae7c5] Yes, that's how the inner cups should have been.

[b:afa94ae7c5][i:afa94ae7c5]Could the Ford Motor Co. seal on the right side by an original?[/i:afa94ae7c5][/b:afa94ae7c5] Yes, it could.

[b:afa94ae7c5][i:afa94ae7c5]Lastly, does anyone know what those ORCOTIPE, letters stand for on the seal?[/i:afa94ae7c5][/b:afa94ae7c5] Just a guess but I would say that the first part of [b:afa94ae7c5]"ORCOTIPE"[/b:afa94ae7c5] Would stand for Ohio Rubber Company. Eagle Picher Industries doesn't fit the last part??

Your hubs are 8N vs 2N as indicated by the smaller circumference. Your top photo is a grease seal as the rubber lip mates to the horizontal surface of the spindle. The bottom is a dust seal as it mates to the vertical face of the spindle. This is the type of seal originally installed at the factory. Either type of seal is acceptable. Also, not a good plan to re-use any seal - It's best to replace them.
 
Thanks Dollar Bill for helping me again. Thanks for the Loctite reference and the thinking that those initials are for OHio Rubber.

If I may ask a follow up: so regardless of what seal I get - I think the dealer will order the dust as I was not specific - I place the bearing in the cup and then press in the seal into the hub - right?

thanks again.
 
Hard to say which type of seal you'll get. Might want to give them a call if you have a preference.
