OTC1266 Fully Adjustable Gland Nut Wrench for Farm and Construction Equipment

Had a problem with the pins reaching the holes in the gland nut. The inside of the tool frame was hitting the ram causing the pins to not reach the gland nut holes.(Bobcat Excavator Arm Cylinder). This was due to the extra thickness of the casting(note the arrows). Did not want to machine off part of the inside of the metal frame which would have weakened it. So I machined out two new pins with an eccentric (off center) stud. This brought the pins (studs) closer to the inside of the frame enabling them to to fit into the gland nut holes. The tool now works perfectly. Maybe you can explain the problem to your supplier and they in turn can get the manufacturer to modify the frame to make an absolutely perfect tool. In the picture on the right you can see the machined "off set" pins correcting the fit to the gland nut. Thanks, all in all great tool.

I thoroughly recommend this tool to remove glands and cylinder ends; along with a 36-inch long breaker bar, it has worked perfectly on a wide range of hydraulic cylinders for me (JD, Cat, Hyster). I don’t like to use an air hammer/chisel except as a last resort, as they tend to chew up the glands/cylinder caps; this tool prevents that and the two different sizes of pins on each side is a nice useful touch. Tool is sturdy and well-built.

I gave 4 stars because of the incorrect pin size. First off, this is a substantial tool and appears to be built to handle a lot of torque. Unfortunately, the reversible pins are larger than the sizes stated in the description on both Amazon and the OTC website. I need to repack hydraulic cylinders with 1/4" (0.250") holes. The small side of the pins that came with the tool measure 0.265" - too big unless I start drilling out the holes to fit.I did contact OTC. I got through easily and Jerry, the customer service person, was polite. He informed me that OTC allows the pins to be manufactured with wide tolerances, up to 0.270" for the small pin and 0.335 for the large pin, a BIG size difference when trying to fit a hardened steel pin into a hole!. He said they've been building them the same way because the pin holes on a lot of hydraulic cylinders are bored oversize. Unfortunately for me, mine are not!It would be nice if OTC and Amazon would change the product description to show the actual size of the pins using the high tolerance measurement in decimal, as 0.270" and 0.335", instead of the incorrect 1/4" and 5/16" sizes

I used this tool while rebuilding the hydraulic cylinders on my Case backhoe. Worked perfectly and fit all the gland nuts as intended. I used this on 3-1/2" to 5" cylinders. Update: I've used this tool to rebuild almost every cylinder on my 855C. One of the cylinders was over-tightened to the point that no matter what I tried, I couldn't get it to come loose (torch, sledge hammer, etc). I finally put a 3/4" breaker bar on this and attached it to my 3/4 ton plow truck with a tow strap. A few tugs later the gland nut cracked loose. I'm really impressed that this tool can survive such brutal treatment!

When buying this tool I wondered why it was so expensive and if it could take the abuse of servicing hydraulic cylinders in our farm shop. Well after receiving it I understand why its so expensive and you bet it can definitely hold up to cylinder rebuilds we perform in our shop!Its really big, thick, and heavy and being a machinist I can honestly say this looks like it can really take a lot of abuse.Take my word for it ... the pictures nor description do this tool justice ... you really need to see it in person to appreciate what you are getting from OTC!

Made repair job much easier and prevented cylinder damage.

A must have for working on Case cylinders, and a great price. I have a 780 so the cylinders are pretty good size and this tool handles the gland nuts just fine, and it looks like I can use it on my small Kubota BT750C backhoe cylinders on my B20 TLB too.

Thought I'd get the more expensive one and actually get a better product...WRONG!! I put the wrench on my cylinder and pulled down with just my hands and minimal force not knowing if it would fall off. Well I heard a snap and it fell off. I picked it up to put it back on and the pin had fallen out. Upon inspection I saw the end had completely cracked into letting the pin fall out! I read many good reviews on this and that's why I purchased it. For a lot of people it has been good, for me...it was TOTAL JUNK! Ended up using a pipe wrench to do the job. Worked great! Hope this helps someone.
