SHENKENUO 3pc Hydraulic Cylinder Piston Rod Seal U-Cup Installation Tool Kit Set Universal J05321

I bought these to install new gland seals in my little front end loader Hydraulic cylinders and watched a video on taking the cylinders apart. Mine have round slide in rings for the gland and I found out that if I turned the gland which should spin freely on this type, It quit leaking through the piston rod. wow. Now I haven't had to use these yet but I have them. Great price and service to receive them.

I needed to replace the seals on my Kubota hydraulic bucket lift cylinders. Every video I watched described the difficulty of installing the inner seals as they needed to be compressed to fit snugly into the seal groove. One of the videos recommended and provided a link to this tool on Amazon. So glad I purchased it as it made the seal installation simple and straightforward. It may not be a tool that I use that often, but even if I only use it once, it was well worth the purchase.

i used the largest one in the set to install a seal on my bobcat 331 bucket curl cylinder. it worked well enough, not the best made tool but for occastional use it's well worth the money

I had two hydraulic cylinders to rebuild on my excavator, which would’ve cost me about $1000 if I took them to a shop. With these tools the cylinders took me about an hour apiece to rebuild and the tools worked perfect for getting the interior seals in place. I like tools that pay for themselves the first time you use them.

If you have ever replaced the internal piston seal on a hydraulic cylinder, you know what an absolute nightmare that can be. Especially on the smaller cylinders. The last one I did was on a small cylinder off a compact John Deere loader. My helper and I were just about to the point of taking it to a hydraulic shop and paying someone just to install that stupid little seal when I finally got it in. I have a few more cylinder jobs lined up and look forward to using the heck out of these.This tool makes it super easy! I tested it on an old seal I had laying around and it is awesome. I wish I had known about and owned one of these a bunch or years ago!

Hubby was very pleased with these when he was rebuilding the cylinders on his backhoe. Saved a lot of aggravation.

This product came to me as expected but when put when putto use to install a wiper seal in the gland, a weld broke. Kinda sucked and put me outa comission. Daughter put a nice bug on it and the tool worked well. Overall kinda cheesey tools but they do work.

no problems

Worked great on John deere gland seal

Fungerar bra.

Only thing different from our shop fancy set to my cheapie set is handle covers. They work well.

Designed to replace the seals on hydraulic cylinders and they did their job

The spot welds are not to good . And I can see them not lasting to long . But if your not doing many they might work to keep ya going .
