7710 APL325 hub seal

Ihave a leaky hub on my 83 7710. There is an excellent thread on his subject but it doesnt answer the question I need answered. The axle is
clearly labeled APL-325. I would like to get the hub seal on hand BEFORE I take it apart..
I have tried my local NH dealer (Torgesons in Belgrade MT) Yesterdays tractors, Messicks in PA, and Steiners
in MI. No one can seem to assure me they have right part for this tractor/ axle combo.
Is there a part # that I should be looking for? Is there someone else I should be calling? I did not call Fawcetts
(Recommended in the archived thread) simply because they were in Canada but maybe I should. Additionally people seemed to indicate that I could get the same part form JD or perhaps Case IH for a lot less money, but without a part # I cant even begin. Thank you Martin

This clearly states it's for APL-325. Seems strange your sources are so confused. There's another page for axle APL-335 that shows some different parts, but the seal (item 38) is the same part number. Is that what you're after?

if it is item #38 your after, part #ZP0750110147 which subs to #81869544 at Messicks for $114.02

you have two crosses at Deere-

There are many axle options and the 325 was least common on the 7710. Basically, follow the parts book very carefully for the APL 325 axle and you will see the application and years. Get the part number and google it. Many sources will appear. Sometimes A&I will have a cheaper listing. Sometimes not. CNH should easily have the seal somewhere for a price or a pound of flesh. Fawcetts/All States should have a listing as well as Fawcetts for a long time have had good independant sourcing on ZF parts. Fawcetts is at this point owned by All States..

Looks like you're taken care of with regards to finding the right seal. I wanted to caution you about putting the new one on. If your old seal used a replaceable wear sleeve on the spindle, this must come off if the new seal is of the 2-piece cassette type, which almost all are. If you try and force the new-style seal over a spindle with a wear sleeve, you'll destroy the new seal.

If you have any doubts, try and push just the new seal onto the spindle by itself after putting a little oil on the spindle surface. If it won't push on by hand (it'll take a little force), the wear sleeve needs to come off. I simply fire up my torch and heat it up red hot, it will then snap in half.

good info Bern! I didn't look over to the right enough to catch the remark on the far right of the item

Ring, Seal, Couple, Need To Remove The Wear Sleeve From Shaft To Use New Ring Seal; (Prod Date) Between 01-Jan-1981 and 30-Apr-1984

Thank you to everyone here. On the other thread they talked about the old vs new(cassette -type) seal but it sounds like at this point cassette type is what will be available. Very good info on the wear sleeve. Thank you to everyone who helped. There is a YouTube video of this job on a 6610 that looks like an APL 325 https://www.youtube.com/watch?v=jxf9GxTzw1U
I got a little virtual courage watching this so I think Ill tackle it, but I plan to use a little more robust jack stands.

Well I got it all apart no problem. The wheel had a fair amount of play when I jacked it up so Ill replace the two bearings and races as well. The seal was the old style single piece and I dont find any evidence of a wear sleeve on the spindle. I do have the split style dowels, another thread suggested that they are prone to self-destruct and I might replace them with solid dowels. Does this sound reasonable?
All the nearest parts paces (CIH, JD, NH ) are an hour and a half away so in the interest of saving time and $ Ill haul the whole box of parts and make sure I have the correct ones from the dealer. Given gas and time costs Ill skip money saving options to just get the correct ones first time. The bearings have a Timken # on the race side but the seal doesnt look to have much ID.

Thank you all! I got it all apart no problem. The wheel had quit a bit of play when I got it jacked up so I think Ill replace the bearings as well as I suspect thats why the seal went out.
The other thread mentioned that the split dowels are prone to failure and should be replaced with solid dowels - does this sound right? Are they just pressed in?
My seal was a single piece old- style seal and there is no evidence of anything on the spindle so I should be able to get the cassette style seal and push it right on. If it doesnt slide on easily Ill investigate further. So mess with solid dowels or not ? Thanks guys

Here are photos of the spindle, the dowels, and the seal. Some of the dowels remained in each side. I assume the solid dowel referred to are just tubes.

Ok, so first things first... do not get your hopes up when it comes to obtaining any parts for that outside of bearings and possibly the main seal. Almost everything else in there is available ~somewhere~ but not necessarily through NewHolland. I would suggest you learn to find these parts yourself, exactly, in the NH parts listings or through Messicks so you get correct numbers. Then start googling and cross reference those numbers. Some days you'll get stuff from NewHolland. Some days it will be Deere/A&I. Some days it will be Fawcetts. There's also an excellent source in Ireland through John Conaty Ltd. YT may also have some stuff listed although probably not so much on FWD axles. Before nnalert most of this stuff was hard to get. Now... even the stuff that ~was~ available is back ordered with no deliver date half of the time. Don't rely on anyone else to get the right part numbers either...
Now, down to the hub... Your pics clearly show a wear liner on there. Snap it off as Bern suggested. The dowels... I'd not give a second thought to unless they're broken. The fact that this thing has lived since 1983 with the original hub seal suggests it's had a charmed life already. I would check the king pin bearings. You may find most of the slop you find in the wheel is found there, and they do wear out. I'd also renew the seal on the shaft and probably the bronze bushing in there unless it shows no signs of wear or leaking. Usually they leak first... Also take a very careful look at the planet gears and their bearings. If they're sloppy at all, replace the bearings. That will more than likely require a quest to find them... although Ireland has hub rebuild kits last I looked.
Again, Deere is often an excellent source of parts if you can use some third party sites to cross reference your part numbers into Deere numbers. Deere is still using a lot of ZF axles in that class of tractor, so even though the models have changed, some parts are more current in their system than they are in NewHollands, so sometimes better availability. Good luck. Keeping these things running isn't as simple as running to the local dealer anymore.
