Review: This an excellent quality tool. - 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.
Review: Serious tool - The pic is deceptively small but It is 16mm thick on the body and 8mm thick on the hinge area. 3/4" drive is needed to drive it. this thing is a serious tool and i love having it for my Case 580B that i use and service myself. This is a well built and very handy tool that allows me to take apart all the hydraulic cylinders on my backhoe, replacing several static tools that fit only once size cylinder.

### ⭐⭐⭐⭐ Nice, but check your hole sizes
*by L***7 on September 1, 2020*

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
