I have a minor oil leak that runs down the back of the pictured Steering Sector Arm. The same arm does not leak on the opposite side of the tractor. Do I need to replace the 1 Piece Retainer and Seal, or are there other options available to me? Tightening only slowed down the leak. 1948-8N
Thanks, Mark :)

My 52 has the screw in the steering column filler and also has the secret bolt hole filler on the side. I had the same problem you're having so following Dell's advice I removed the side filler bolt, got a new one of the same size and thread, drilled it hollow lengthwise with a drill press and threaded in a zerk in the head of the bolt. That will allow me to inject the cornhead grease. Problem is I can't figure out how to get the rest of the old oil out so I haven't used the cornhead yet. In fact I haven't even found any cornhead yet. But I'm ready when I do.

HVW, corn head grease is not made by J.D. They buy there oil and grease from some one else just like everybody else. We stock corn head grease at our New Holland dealership,it carries N.H. name,so might check different places. If you remove the two bolt plate you will have to screw the adj screw and lock nut out of the plate I think.

HVW..... ....ain't no big secret to gitt the OLD OIL OUT. Just remove the 2-bolt plate that you see in the picture, don't mucka-round with the adjusting screw/locknut. Let the old oil drain out down the side of yer tranny into buckett. Ragg-outt the muck in the bottom of the box. Flush with solvent of yer choice. I use paint thinner mineral oil. Simple, eh? ..... ...Dell

I never thought of doing it that way. That's exactly why you make the big bucks. Thanks Dell. Now if I can find that cornhead grease!

I am a believer in the corn head grease from JD. Put that stuff in there and forget about it.

I put it in all gear boxes that are a few decades old.

Dell has the answer, that is if you can sleep with green stuff running through the veins of that red belly tractor lol.

You can drive a new seal in rite on top of the old one, plenty of room for 2 seals. Whan I rebuild one I leave the old seal in place.

As Dell said you can fill it with thick lube like grease, or tear it all apart and replace parts. Most put the lube.

Mark..... ...I hope you realize yer pictured 8N steering gearbox is the "late" model with adjustable gearmesh screw. They changed at s/n: 8N216989, mid-1949. It is a better box and retro-fittable inplace of the "early" steering gearbox with 8-bolt gearmesh scheme.

I doubt that there are "other options"; but recommend you use 2-tubes of "sticky" corn-head oil from (byte my tongue) John Deere dealer. It is so thick that it almost "can't-leak". It also lubricates the under-lubricated upper gearbox bearing that the ball-nut turns in. That bearing is the "major" cause of steering slop. (not the adjustable steering sector gearmesh)..... ..Dell

I thought something was different in my steering set-up, since it did not match what the Master Parts catalog has shown for the 1948-8N. The steering column has the screw at the top of the column under the steering wheel, obvioulsy for a liquid gear oil. How would I inject the "Cornhead Grease" at this location? Should a grease zerk fitting be installed there? Or which bolts near the base of the steering column would I remove to inject this grease?
Thanks, Mark :)

Mark..... ...while the rare (late-52) top steering column fill'em-up is good for OEM 90wt gearbox oil, I don't think the THICK sticky cornhead oil would dribble all the way down the column to fill the gearbox. LOL.

I believe that even the late-52 steering gearbox still has the "secret" fill'em-up bolt hole. Remove the R/H steering gearbox sheetmetal bolt (opposite the one you have yer flatbraid bolted to) and PROBE witha "J-hook" piece of bailing wire down at the bottom of the bolthole should be a "secret passage" into the gearbox cavity.

There are several ways to make a "ZERK" fitting adaptor to fit the 7/16-14 threaded box-hole. (go shopping, brass plumbing, etc) A big cartridge greesegun and squirt-em full. Simple, eh?..... ....HTH, Dell

One problem with using grease, there is a welch plug in the bottom of the steering box that can be forced out if too much grease is pumped in.Then all lube runs into the clutch housing and the box has none.Use a soft cup grease.These late steering boxes have two seals on each side,Another problem is the top bearing on the steering shaft.This bearing wears the steering shaft.As this happens the steering shaft moves upward and the skirt fastened to the under side of the wheel no longer fits down over the steering tube.Rain water gets into the box and the gear lube floats out of the box.If there is a gap between the skirt and the tube you will have trouble.A new shaft is one fix or you can clamp a short lehgth of radiator hose over the skirt.If you do use grease it must be a very soft grease that will run into the gears .I put cup grease into a leaking JD H box 40 years ago and it is working well.If you do grease a Ford box watch for grease coming out of the leaking seal.I expect excess grease would come up and out of the steering tube before the welch plug would be forced out.
