Description
When you need to limit how far your hydraulic cylinder extends or retracts, these stop blocks are exactly what you need. Whether you’re adjusting a loader bucket’s tilt angle or fine-tuning the reach on a hay spear, having the right stroke control means your equipment works exactly how you want it to. This cast iron set gives you five different thicknesses so you can dial in the perfect positioning.
What You’re Getting
- Complete set of five blocks in the most commonly needed sizes: 1 inch (2 pieces), 1-1/4 inch, 1-1/2 inch, and 1-3/4 inch
- Cast iron construction that won’t bend or crack under hydraulic pressure like aluminum might
- Direct replacement for Monarch parts 639123 and 9120, so you know they’ll fit right
- Precision machined to slide smoothly on your cylinder shaft without binding or sticking
Built for Real Farm Work
These blocks fit any hydraulic cylinder with a 1-1/4 inch shaft, which covers a lot of loaders, hay tools, and implement cylinders on mid-size tractors. You’ll find this size on everything from front-end loaders to three-point hitch cylinders. Having multiple thicknesses means you can stack them to get exactly the stroke length you need.
Made to Last
Cast iron might be heavier than aluminum, but it’s tough as nails and won’t deform under pressure. These blocks will handle the constant cycling and high pressure of hydraulic systems without wearing out. The smooth machined surfaces ensure they’ll slide on and off your cylinder shaft easily, even after years of use.
Good to Know
Installing these is simple—just slide them onto your cylinder shaft and position where you need them. If you’re stacking multiple blocks, put the thickest one closest to the cylinder and work your way out. Keep a few drops of hydraulic oil on the shaft to help the blocks slide smoothly, and check occasionally that they haven’t shifted during operation.
