I used your cylinders in my rebuild of an old John Deere loader. It has worked out okay for a fraction of the cost of OEM.

One thing it does every time I start the tractor and raise the loader is the loader judders like something is binding. After a few cycles it works smooth. It has done it from the very first cycle so I think it is in the cylinder pistons. All the loader pins were greased on assembly and slid in smoothly when they were installed. They have been routinely greased so I don't suspect any of them are the cause.

Other than that the loader operates okay and has increased travel and lifting capacity over the original 420 cylinders.
