3 Pack Hydraulic Seal Installation Tools & 1266 Adjustable Gland Nut Wrench & 7463 Small Universal Gland Wrench, Hydraulic Cylinder Spanner Wrench Piston Repair Seal Kit, Farm & Construction Equipment

I'm relatively new to this. I tried "making do" without these when working on my 35+ year old Kubota 4530B Backhoe that likely spent its entire life outdoors. It apparently had the original seals and was never torn apart. I ultimately had to drill out the holes to the 5/16" size pin on the first cylinder. I didn't have a 3/4" socket wrench, but made an adapter out of a spare short 1/2" drive extension by grinding 4 square sides on it. until it fit into this. That worked well enough to bust a breaker bar and max out my 250lb torque wrench... it wasn't budging, but the pins didn't break, either. I soaked it and left it for the night. The next morning I walked over to "old man that knows how to do everything" neighbor and borrowed his 3/4" inch socket and ask for any tips. He mentioned to bang around on the side of the cylinder, where the threads are, with a hammer a few times... and that you can use heat as a last resort. Well, I banged all around the side of the cylinder for a minute and got out the propane torch just to heat it up a bit. I put the new wrench on it and I don't think I applied more than 100 ft lbs of torque before it wound right out. The next cylinder was much easier, I guess since it wasn't directly exposed to the weather... I used the 1/4" pins and they worked just fine. Upon installing the seals, the install tool is so much nicer than trying to wedge them in with your fingers... so that was nice to have, too. Overall, I beat this thing a good bit, and it took it. I believe it was money well spent.

Used it today on a skid steer cylinder and it worked great. Both the spanner wrench and the install tool outperformed their pricing.

worked as stated

Decent enough

Junk. Fell apart almost immediatly. If you have ever used the chepo harbor freight pullers that loose nuts and bolts and is extreemly frusterating but can work? Well this is that version. Couldnt even get my cylinder to budge. I wasted money, they hydraulic shop will fix it right and give you insurance. They are better than most.

These work very well it’s a must need to rebuild hydronic cylinders

Great pair of Spanner wrench set. It served my purpose on my bobcat skid steer hydraulic boom arm lift cylinder.

They worked well enough for most of my glands, but ended up with the quality OTC for a really tough lift cylinder. The one from this set rounded a little and then was tough to get a good hold.
