Where did this seal come from?

[FredSG]

Hello,

I was out snow blowing with my JD 4310 Utility Tractor when I noticed this seal seating on the ground. For the life of me can't determine where it belongs. Checked my parts catalog and my service manual, but there are too many similar seals like this one. How can I trouble shoot to figure out where it came from?









Anybody help . . . PLEASE!!!

It looks like it could be a grommet to protect wires or hoses from rubbing the metal where they go through a body panel

Looks more like a seal than a grommet. You have any hydraulic cylinders that diameter?

Fred,
I will look at my 4410 tomorrow and try to find something that looks like that. Since there doesn't appear to be any grease or oil on it, perhaps it's nothing vital.

 

[FredSG]

Thanks guys, appreciate the responses. LoudonNH, look forward to anything you can offer. I was told to look at my front rims for a grease/oil leak, but nothing leaking as far as I can tell. Under the 4310 looked and looked but didn't find anything like a leak anywhere. Got to figure this out . . . more snow is in the forecast. Do I use it as is and run the risk of bigger problems?

On closer inspection found the following imprinted on the seal:

DMS476, 50007, MTP, Taiwan: Checked the JD Utility Tractor Parts catalog but came up empty.

Are you sure it's a seal? Looks pretty clean and rusty.

 

[MossRoad]

One more thought.... maybe its not from the tractor at all? Anything else ever in that area?

 

[pmsmechanic]

Here is my guess. I think it's a seal to keep dirt and water out and not oil in hence no oil leaking. If you look at where your front wheels turn horizontally on the front wheel assist housing you'll find where it I think it comes from. The part number is LVU25945 (number 33) and you should be able to find it on this page. John Deere - Parts Catalog The pictured seal looks like it's seen better days but it's a lot of work to replace it. I would shine up where it goes on the front axle and then just slip it back into place and hold it there with a zap strap. That will keep you going until you can get a new one. Before I would take the front end apart to replace it I would cut and stretch a new one enough to be able to glue it back together with windshield installation glue. I don't know what the stuff is called but my buddies use it all the time to repair their CV boots on their quads. If it can hold up to that then gluing this seal back together would be a piece of cake.

I call those face seals.....used to keep dirt off the inner seal of a drive shaft or hydro-trans

Not sure where it would be on your JD

PMSMechanic,

BLESS YOU, BLESS YOU, thanks so much for the information. You are 100% correct. Found the page in the JD Catalog. Many, many thanks to you and everyone else who helped me with this problem.

Is TBN a great place or what?? :thumbsup:

I best take a look at my 4300, as the same shield/seal by that p/n is on it as well. Thanks for the heads up.

 

[pmsmechanic]

Ya I think I'm going to take a look at mine too. I'm thinking the tear comes from the tractor sitting for a while with moisture in behind the seal. The seal lightly gets rusted on to the metal and the next tine you turn your wheel it's torn and can fall off. If you look closely at the pictures of the seal it's cracked in a few places other than where it's torn. My thoughts to preserve my seals if they are still good would be to pull the lip of the seal down and slip the hose from a WD40 can behind and lubricate the seal a bit. I noticed in the parts book that there were two seal numbers with the first one being superseded by the second hopefully improved one.

Hello my friends, you guys are terrific :thumbsup: :thumbsup: :thumbsup: :thumbsup:

Here is a diagram from the JD Parts web site. The description with ALL part numbers is actually three pages long. I've only included the diagram page with the correct part # in red on the diagram itself.



Thanks again to all for your help with this find :cool2: :cool2: :cool2:

I'm glad the problem is solved! Thanks for the diagram Fred.

Hello again my friends,

I Emailed the photos to my JD technician and he just replied suggesting that the seal I pointed to in my diagram WAS NOT the correct problem seal, as it is closer to 4" in size. He directed me to #22 in the same diagram which he states is closer to the 3" size. He states that JD has a new style for that front outer hub.

FredSG

 

[pmsmechanic]

And I'm still going to stick with number 33 in the diagram. If number 22 seal was missing you would have an oil leak....unless there is no oil in your final drive. Number ten is the sleeve that number 33 rides on if I'm reading the parts drawing correctly.

 

[FredSG]

pmsmechanic,

This is the diagram from my 4310 technical manual. Same information just identified differently





So on this diagram, the seal is letter I . . . is that correct? as it appears to correspond with #33 on the previously posted diagram.

A bit confusing for me, so please clarify, if you don't mind, please.

FredSG

 

[LoudonNH]

Could it be the seal from one of your hydraulic filters?

 

[pmsmechanic]

Yes FredSG I would agree that "I" would correspond to #33 in the parts diagram. And I don't think it would be as difficult to replace as I initially thought. If you take the bolts out of the elbow part marked "G" you can just take the whole final drive to the work bench to do the job or a mechanic if you don't want tackle it yourself. You would just remove the cover "W" and start removing shafts, gears and bearings till it comes apart. Lay everything out in the order you take it apart and then it wouldn't be hard to put it back together again. I have a service manual and can give you the specs or someone who is less computer challenged than I am can scan the pages and send them to you. You can also buy whole service manuals online as pdf's for a very reasonable price.
