New Holland TL90 - Lower Hitch Arm Seal Replacement

- I have a 2001 New Holland TL90 that has a lower hitch arm seal leaking hydraulic oil. I am replacing the seal and bushing, then showing how to install the lower unit back in to the tractor.
I used two cameras to video this project:
Canon Vixia HF G21 with RodeLink Lapel Microphone
GoPro Hero 5 Black with a Rode Micro Microphone
I just did this on a 1997 NH 4230 with 2050 hrs. The general components are the same as the video. I replaced only the seals because the bushings seemed in good enough shape plus only 2050 hours and never plowed, only mowers and sprayers. I think some of the problem on my tractor may have been water in the lower torsion shaft housing. The housing was full of water because it is lower than the hydraulic drain plug. Plus, the original seals are junk, make sure to get the newer style seal down in this video. If i was to keep this tractor for a longer period i would drill and tap the shaft housing for a small drain plug to get any accumulated water out. This was a great video, thanks for posting.
Just to add: (With lower unit off tractor) Instead of rotating the bushing with screwdriver, use a 15/16 socket against bushing from the inside. Smack the rod against the socket with brass hammer. Excellent video.
Great advice! Thank you!
Great video. I have a case jx80 and changed both seals. I did remove the whole component and changed the seal from the comfort of my bench vise! Thanks !
Thanks from Finland, I have a same seal problem in Fiatagri 70-90, this video was great help for me👍!
Hi. I must do similar repairs to my Fiatagri 90-90. I’m wondering if you have any tips other than those shown in the video. I am afraid to remove the shaft in case there is anything floating on the shaft inside the case. Perhaps that’s not the case however.
As usual with any job I do.....I had to not only remove the housing but then heat it extensively with a pear burner. Even then the sleeves didn't come out easy. I attempted the method of turning the bushing sideways. The rotating piece of the bushing broke and fell out the bottom. I could make 100s of videos for "worst case scenarios" and "wow, we have never seen that happen before". Its the norm for me.
Dang, that sucks!
About to go do this same job on my TL90A. Thanks a ton
You’re welcome!
Thanks for the info. Just started on T4 95 looks about the same
Great video!. My jx80 started leaking there and the two reactors are very similar!
Thanks man it was helpful it worked out well with your help it reached out as far as Zimbabwe stay cool
Wow, so cool to hear that! Glad it worked out for you and I appreciate the comment!
DANNY SANTANAA,thanks is good feed, I had thesome situation now I can deal.
Tried to drive the seals out like you described. Broke the shaft guide in half. Had to take the unit off and had a hard time getting the seal out. A terrible design.
Dang, I hate that happened to you. Thank you for the feedback.
great movie, big help!
Very helpful information!
Hello thanks for this video I have leak for few years and already changed seal bushing and shaft but the leak is between iron part of the seal and mean part number 5116242. So now I have to change the mean part number 5116242 and would like to know how to take it of because I've tried but never did, when I unscrew the mean bolt under the mean part doesn't move so do I have to move it strongly or do anything else regarding the lever ? Regards
tell me, my friend, if I want to replace the lower arm seals, do I have to drain all the oil? Is it enough to just remove the entire shaft without draining the oil? I have a New Holland TL90 tractor from 2003.
Do yourself a favor and drain all the oil into a clean bucket so you can refill it after you get the seals changed.
Good explination
Thank you!
If oil is leaking out around the shaft, then that means the spherical bearing is worn Remember all the pull of the tractor is through those two bearings.The shaft also rotates through use. Replace both spherical bearings and both seals together. I am not a fan of lower link sensing because of oil leaking and the work needed to fix it.
Where's your farm located? Great video
Thank you! I’m in Southern Illinois in Jefferson County. Thanks for watching! Glad you liked it. What tractor do you have? Got a leaking seal?
Do they make a tool to remove the seal
How to remove the busing?
The seal is leaking because the bushing is worn.
Does it drain the whole trans
What is the reason for the bearing and seal? What moves the requires lubrication? I am thinking about fabricating the shaft and making a bolt-on version. Thoughts?
Exactly. No reason for that shaft to go through the housing other than to sell a few hundred dollars worth of parts when they start leaking. I have a TD95D and is is full of ridiculous design flaws.
@@65snake55 Mechanic explained to me the shaft is flexible and has levers and sensors to detect strain on the three-point stabilizers. When strain is detected it lifts the implement to avoid overload. Makes more sense but still a PITA
@@jwhoweth I didnt know that. I am about to replace those seals and bushings as well as the PTO bushing.
Hi
Were I can find the part-numbers for New Holland TL serie parts?
Thank you.
I use www.messicks.com, in their search bar, type in TL90 or whatever series you are after and then you can click on the search results that come up.
@@WelshFarms Thank you very much for the suggestion.
I also found a very useful website (it will be necessary to use Adobe Flash): ngpc.cnh.com/Lp/es/ds?dealerhash=877D0F77-9657-42F5-846F-FDBC8E66B3FD
How can you remove or pull the cap/spacer without pulling the housing out?
Matthew Mamangun knock the shaft into the case, passed the bushing, rotate the bushing and then hammer the shaft back in. It will knock out the cap, seal and bushing.
