- So what did I do wrong? This should not be this hard to do. I talk about seal kits and what to look for if there is issues. OEMs change parts all the time and sometimes you can't even trust your dealer to get you what you need.
Don't just take your dealer's word for it, research it yourself. Luckily New Holland has a decent parts catalog online and allows anyone to dig through it. I went to the New Holland dealer to sort it all out and explain the whole ordeal in this video.
Hydraulic cylinder seals should go in easy. Don't keep working at a seal that does not want to go in. There is probably something wrong if you have to force your way through the kit.

Thank you for taking the time to help others in the same boat. You've undoubtedly helped many frustrated diy'ers like me. I have a 1998 NH 555E with the same issues. I take pride in doing my own repairs when I can, so when you find out you've been sabotaged, it's very discouraging.
Thank you. It was very irritating to find out I was setup for failure on this fix. Luckily it all worked out in the end and I learned a valuable lesson on parts and changes.
Great point about stopping -- when you figure out that a seal does not want to go in...
Video is good to go. Great gouge. Thank you for taking time to post.
Thanks for watching! Glad it helped.
Oh crap, I have the after market seals and now I’ll probably have to get the new glands so they’ll fit my 1995!
I’ve used a ton of aftermarket kits and it’s a chance of getting the right seal and size 😊
Yeah, that was frustrating. They only had one part number for this tractor so I did not know the gland had changed. I blame the manufacturer for changing glands. ☹️
When you run in to this again, go to a hydraulic seal supplier. I own a hydraulic repair shop and have lots and lots of seals (this is not a sales pitch) and I hear what you said about the seals being obsolete almost daily. New Holland, John-Deere, CAT, etc.....obsolete these parts under THEIR system, but the seals are most likely still made. I shock people every week that they can buy just a rod seal, or just a piston seal, even though they are ‘obsolete’.
Seal Mfgs aren’t dictated by one or two OEM’s. As a seal supplier, you’d be pleasantly shocked what you can still buy. Don’t buy hard parts unless you’ve checked with some grey haired, cynical, crabby old man that can help you without forcing you to buy more parts. I’d also be very careful about crap sold online. After all, the kids toys from China had lead paint, really makes me think those aftermarket kits are.........better?
Odds are, you’ll be pleasantly surprised.
That is great information. Thank you! I was so pi$$ed when I found out the issue. Why pay 100s to replace the whole gland for a few rubber seals. Great information that I will use on my next replacement.
As a seal supplier, I agree with Albert. We can machine or match up almost any seal even if it’s obsolete. Happy to help either of you out in the future! We speak hydraulic repair.
It's called the piston and yes that one looks different than say Cat or Case ,John Deere
Glad I got it working after all that.
Albert Peugh says that the seal kits are still available so I was wondering if you should look in to getting the correct seal kit for the old gland and keeping it as a usable spare or replacement for one of the other cylinders.
I did keep it, so I may do that. Thanks for letting me know.
I've had to replace every gland on my LB75B. Infuriating!
I am not looking forward to that.
I heat hyd oil to 180 degrees and let seal warm up to install it easily kinda but I bought the three finger tool set
I did not think about heating up the seal, but it makes sense.
You also put that seal from backside on my Case 480 D
It was a pain.
Looks like the metal part of your outer wiper is still in the gland. No idea how to get that out so the new one can drop in.
That is what I was thinking in the beginning, but the seal are all rubber. These did not have metal ring around them from what I could find.
That is soo dirty that they discontinued your seal kit making you buy a new gland. I'll have to keep that in mind when I do my 1995 backhoe
I will admit, I was not happy about it. Even the aftermarket kits were for the new gland only.
@@SeidelRanch lucky my boom lift cyl. kit was the same. Looks like they are all set up about the same.
literally any decent shop has or can get you every thing there...In my shop i probably have enough to rebuild 12 of those...mcu wiper twin lip rod seal its a cat buffer even though that looks like a case cylinder and a ps1800 piston seal....nothing in that kit is special...equipment manufacturers dont make seal kits they buy them from seal distributors or manufacturers...even if they discontue them on the dealer side those same seals are used in thousands of other cylinders
Long story short is you should have took the gland to good local hydraulic shop and they would have MEASURED old gland and gave u a replacement seal and saved you a $160. Forget oem part #. Measure measure measure!!!
Yeah, I wish I would have done that and know better now.
its a u-cup not a c cup....the one below is call a buffer and this takes me literally like 45 seconds to install all 3....that install tool is a waste of money....and so was buying a new gland....ive been doing this professionally for over 20 years...you wasted more money than it would have cost to have it rebuilt by a good hydraulic shop....not all shops are good but this rebuild tops would have been under 200 bucks...
That is part of the problem around here. You can't find a good shop that does not want $1000+ just to look at it. From what I remember the local hydraulic shop (which most say to avoid) quoted me $800 just for labor and it would have to be taken off the tractor and dropped off. Then I would have to wait months to get it back. I have learned to just try it myself and learn as I go. The issue I had here was that none of the parts I ordered were the right ones. If I could have found the right seal kit from the start it would have been $35 and done.
Takes money to go to school. Learn from your mistakes i have done it many times.
Haha, so true. Every mistake is a learning experience. Now I look all over for those part updates before buying anything.
