Be careful. Apparently there are several different mfgrs of the LW-6.
Not all of the hydraulic cylinders are the same; some have split ring keeper ends, and some have screw on ends (rod seals may differ). The pistons are different too. Some have a nylon T-shaped guide, and others just have o-rings. So far as I can tell the piston cup seals are the same. Don't expect anything exotic like chevron packing, these things are real crude and basic.
