Hydraulic Cylinder Rebuild - Case 580E Backhoe Bucket Cylinder 

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'm glad you enjoy! Thank you for your comment!

You get what you pay for (most of the time). I hope it’s a good deal and not much work!

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 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.

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''

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.

I used a light smear of vaseline, as pictured in the background during the installation.

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!
