The 871 Series features a ductile iron bearing cap rated 117% stronger than gray iron, an o-ring sealing configuration between the housing and bearing cap for improved clamp load, and a compact housing profile that reduces clearance concerns during installation.

Nine gear ratios and thirteen output options give this series broad application flexibility across fire and rescue, truck crane, pumper cleaner, and refuse markets.
