I have an early Rockland Quick Coupler on my 1979 Hough H80B Pay Loader.
Sadly, the hydraulic cylinder must have failed at some point in the quick coupler and the hydraulic cylinder was removed and a wooden block put in the cylinder's place to keep the pins in.
Unfortunately, Rockland knows nothing about the coupler, what pattern it is (CAT, Deere, Komatsu, et cetra), or any parts used in it.
To my eye, the Rockland coupler uses a fixed in place, double-acting, twin-piston RAM like what is in the photo below but for the life of me, I cannot find a generic version because of my inability to describe the type of cylinder accurately.
My question is this: what is the generic shorthand or description of the same type of cylinder used in the quick coupler below?
Thanks for any and all help!
