- We blew the seals on one of the 400e loader hydraulic cylinders. We show you how to take it down, repair, and put it all back together to get back to work!
Thanks for the video and encouragement! I was on the fence to do it myself or take it to an outfit that does this sort of work. I ended up doing it myself and the outcome was great! I'm now over my learning curve and am working on my second cylinder. Again, thanks!!
Excellent video. You just saved me a lot of heartburn, and money, after I popped the seal on my loader. Thanks.
Great video, I decided to pay someone $100 per cylinder to rebuild mine, I didn't want to clean up hydraulic fluid from all over my shop.
It's crazy that the seals cost about the same as gold per ounce.
Thanks, yeah i definitely got fluid all over lol thanks for watching!
Nice job. Glad you got it fixed
I just came across this video. Excellent work. Keep the repair videos coming 👍🚜
Great work buddy!
Way to go man! Great video!
Exactly what I needed to know to fix my AHC10186 cylinder
Glad it helped!
Dude, way to go!!! How many more titles do you have? Did not know you were a heavy machine mechanic... NICE!!!
great job!
Very helpful!
I used a hose (screw tighten) type hose clamp/strap to compress the lock ring & the piston seal, kind of like if I was putting in a piston with rings in a cylinder block. Was there a o ring under the piston seal? Thanks for the upload.
Proud of you boo
You the man!!!
That video really helped me, thanks,Keene ridge road
Thanks: hoping to apply some tactics to a 78' New Holland Skidsteer with the same issues. Great video.
Working on a 720 John Deere loader but the orange wedge tool seems to over lap is that ok?
Thanks you hope I can do it
You didn't show replacing any of the seals? Direction of rod seals would have been especially nice to see.
Pretty sad a 2021 already needs seals my old 2008 3005 has never had a hydraulic part 1 put on it and I beat the poor thing to death lol. And your suppose to change the ORF O-rings anytime you take a fitting loose
Did you take orange. Ring out when you put cylinder back in
I'm curious of how many hours were on that tractor because I've got a John Deere tractor too. And after like a thousand 1200 hours the cylinders just go bad
Did you make a video on how you welded the fitting back on.
Unfortunately no sir, needed to do it fast to get back to work
Great
what is up with the weld on the fitting where it attaches to the cylinder?
It's a repair job which probably caused the seals to wear out due to the weld which probably tweaked the cylinder out of round.
I have a jd 3043 d with a 300e loader. Is it necessary to bleed the air out of the hydraulic lines? My bucket drops during operation. I bought the o ring kits. But my cylinders are both fine. No external leaks and they both hold pressure. Is air in my lines causing this issue? I had a few lines shake loose while operating a rock bucket. Any help would be greatly appreciated.
"Implement drop" with no visible Hydraulic Oil leaking out of the system is usually caused by bad seals, O-rings, Gaskets etc allowing fluid to leak internally across one chamber/port to the other side and finally back to the tank. If your leakdown test shows your Cyl's as being fine then you could have LOTS of displaced air being introduced into the system. Some signs would be a WHINING Hyd Pump (air cavitation in a pump is NOT good) Lack of lifting or digging power, High temp in your lines, pump, or tank.
@@phoneapps7351 I bought a used (I think maybe 07-09) JD 4100 with the 410 fel. Since l bought it everytime you went to raise the bucket it would drop down about 6"-9" before going up. And the bucket would leak down. We were doing some work this past weekend and blew the seal in the right lift cylinder. I'm planning on rebuilding both lift cylinders what with the age of the unit and the right side going out. I'm hoping that will take care of the bucket drop and leak down as well. Other than JD, Amazon and eBay, where is the best place to get good quality seal sets at a reasonable price? Hopefully that all aren't now being made in Chy-Na! And with rebuilding the cylinders and the loss of fluid from the blown seal l guess l also need to invest in a 5 gal bucket of fluid as well. 🙁 😂
How do you bleed air in the line,thanks
The fluid (and air) circulate back to the tank where the air gets dropped and so it's basically self purging/bleeding the air as long as your tank has plenty of fluid.
I try and avoid using adjustable wrenchs and sockets for a punch.
lol you should use a hammer drill...but I am going to use this wrench....lol Awesome !!! you da man !!
Yup, use what you have on hand lol
when did you remove the tool that you installed toremove the rod ass.?
Before you put the rod assembly back in. I tried installing the rod assembly with the tool in cylinder and it came out.
I wish he would have showed those steps or sped it up cause mine is different I think.
After your repair, at app the 21:32 mark, it looks like the outboard snap ring was not in place. It was up by the bucket and sliding along the rod. If that was indeed what I saw I hope you noticed it before any damage was caused. (Nice Tractor BTW)
Actually that is just dirt buildup at the end of the cylinders travel next to the green paint... i have the exact tractor and mine looks like that on the end when i use it
..not the outer snap ring as it is much larger
If you look back around 5:22 you can see that there's a lip at the end of the rod on that piston, for some reason.
I just had one done at the tune of $120.00 for labor alone …..

A video like this, even though it's ok, is sht when they skip over everything that the title was actually supposed to be. Seems like according to the title, the video should have been about installing the seals. This was completely passed over.
Jumps between steps too much
Not much use of making a video if you leave out the important parts
