The 51410 will work on all Cubs but was designed for the HG hydro's in the cyclops line, 2k &3k machines. The 51084 has the anti-drainback valve and works well on the older machines with the Sunstrand pumps but not on the newer machines with the HG pumps. The 51084 will keep the pump full of oil so on the next start up it doesn't start dry.
