Unfortunately no, but the assembly is very straight forward. There are only 5 parts, a nylon washer, the o-ring, a flat washer the retaining cap and a snap ring. Also I didn't mention this but the reason the ram was leaking was the snap ring was cocked in the assembly and ended up scoring the shaft. Ended up emory papering the scratches out to get it to seal. Bottom line if I was able to get this to seal with a scored shaft, I would think everyone should be able to seal up there units.
