Boom lift force dropping or hydraulic oil weeping from the rod on your ZX120 or ZX130? A worn 9185636J boom cylinder allows internal piston bypass to bleed away lift force until the machine can no longer hold a loaded boom, while a scored rod seal leaks oil across the cylinder head. RITO supplies this heavy-duty replacement boom cylinder to restore full ZX120-series boom lift and clean, seal-tight operation.
