Hydraulic Cylinder Rebuild - Case 580E Backhoe Bucket Cylinder
ฝัง
- เผยแพร่เมื่อ 18 พ.ย. 2020
- While lifting the boom and curling out the bucket, all of a sudden hydraulic fluid started spraying everywhere. Why this seal failed the way it did, I don't know. Dirt could be a factor as the wiper seal was completely deteriorated, but the remainder of the rod seal that didn't come to pieces looked decent.
Anyways, in this video I replace all the seals on the cylinder.
Discovered your channel tonight and subscribed. Enjoying watching your videos. You remind me of myself at your age with your determination. I am almost 72 now and still working on my own equipment. It keeps life enjoyable and interesting. Your videos are simple, informative, clean and no noisy, irritating music. 😊 Keep them videos coming. God Bless America!
Great video, I appreciate that you didn't add music to entertain me.
Very well.
Eh visto varios vídeos, y te felicito porque tu eres muy cuidadoso y precavido. Tu forma se trabajar se parece mucho a la mia. Exelente trabajo.
sprays 1/2 gallon hydraulic fluid demonstrating the leak
also- carefully holds tray under cylinder to catch 1/4 cup of fluid
lol
great video though!
It was more so to retract the rod, but you're right, totally counterproductive! I'll try to be more conscious of that in the future lol. I'm glad you enjoyed it!
@@fixaday is it necessary to retract the rod? I mean I know there’ll be fluid that comes out as you pull it out but could you not collect more of the fluid that way. Just curious before I do mine - not being a smart arse.
It’s more so about the volume on either side of the piston. The side with the rod had less volume, so less fluid lost during disassembly. In my case, I sprayed out so much fluid that it was counterintuitive.
This is different if you can angle the cylinder upwards, so fluid won’t run out during disassembly. In that case, I’d extend the rod before disassembly.
In all honesty, it’s going to be a lot of fluid loss either way. It’s likely negligible in how you disassemble it.
I used a 1/2" pneumatic impact wrench on the piston bolt. Nothing moved. Then I used a 3/4" SK ratchet with a cheater bar. The 3/4" drive broke on the ratchet. I took the piston to local rental company. Mechanic used the Milwaukee 1/2" M18 High Torque Battery Impact Wrench and the bolt came out. Same Impact Wrench you have, nice. I'm getting one.
I'm subscribed, going to get a 580 e in the morning. Prob going to have to do much of the same repairs you have.
You get what you pay for (most of the time). I hope it’s a good deal and not much work!
Thank you for not saying anything. Now I know nearly as little as before I watched
Great videos Wayne. Extremely helpful (& entertaining). Where did you get that pin tool? I’d like to buy one. Much obliged to your wife for being a trooper filming!!! Most videographers (aka wives or other family members) are a disaster capturing the important moments, your wife is always ON POINT.
Glad you found it helpful; thank you for the support! Which pin tool are you referring to?
The one you used to remove the round cap with two holes. The tool has two pins that go inside the holes to create torque to loosen the cap.
Ah, gotcha. It’s an adjustable gland nut wrench (pin/dowel style). This one works for two sizes, one on each side. I can’t remember what size they are, but possibly 1/4” and 5/16”. They’re readily available online, prices range from $20-$50.
I’m loving the videos 👏🏻👏🏻👏🏻
I'm glad you enjoy! Thank you for your comment!
Great video God bless and thank you!
Great video mate. Now to fix mine! Do you have the torque settings for the gland and the screw in the bottom of the piston?
Thanks! Yes, the gland nut is 100-200 lb-ft (video was 200) and the piston cap screw is 1000-1200 lb-ft (video was 1000).
@@fixaday thanks man. What is the size of the bolt/screw in the end of the piston pls do I have the right size for my impact wrench.
@@gregdunstan568 I used a 46mm socket and it was snug. It's actually a standard bolt, I think a 1-13/16''
AY QUEDO LISTO PARA TRABAJAR MUY BIEN ANIMO AL 💯
Hi Wayne, nice video. What size, about, was the bolt through the piston? Did you just use a battery impact to remove it? Thanks
I used a 46mm socket on it. It's actually a standard bolt, my guess is 1 13/16'' head, but the 46mm fit snug.
I did use a 1/2'' battery impact. I'm not sure if it was torqued to spec and had threadlocker or not before removing it though, It came loose easily.
What are you taking in school Wayne,if you don't mind the inquiry? Regards from Alberta, CA.
I don't mind at all! I started off with an AS in automotive technology, but have shifted and am currently pursuing a BS in Mechanical Engineering.
@@fixaday Great,wished I had went on and took Mechanical Engineering,old school mechanic,some Diesel,saw some things through the years that made me scratch my head and wonder what were they thinking when they designed it that way,too late for me,almost 72,retired at 62!Good Luck in your career!
What torque did you use on the piston nut and the gland?
100-200 pound-feet for the gland (if it uses a set screw), I set this one to 200.
1,000-1,200 pound-feet for the piston cap screw, using Loctite 242.
no lube over the new seals during initial slide in?
I used a light smear of vaseline, as pictured in the background during the installation.
I did the same thing with the stinking set screw.......
Hi Wayne my name is Gary Holt Im from a little town here in Missouri called Cape Fair it's 15 minutes west of Branson Missouri anyway my question is whereabouts do you live? I I'm just curious because as we both see we're both HOLT'S so I figure we are family somehow?!LOL
Holt seems like an uncommon last name, but I am from Calhoun, Georgia. I don’t believe I have any family from that region but you never really know!
One down, 10 more to go!!! LOL!
