Western 77475 – Slide Box Wing Cylinder Ram Assembly (1-1/2″ x 13-15/16″ DA)

The genuine Western 77475 Ram Assembly serves as a heavy-duty, double-acting slide box wing cylinder engineered to mechanically actuate the telescoping wings of expanding power plows. Measuring exactly 1-1/2 inches in bore diameter with a 13-15/16 inch stroke length, this factory-original hydraulic ram delivers uniform power during both extension and retraction sequences. Commercial fleet mechanics install this authentic wing cylinder inside Western WideOut (8-10′ and 8100PP configurations) and Fisher XLS multi-width plow networks to replace bent rods, scarred housings, or pitted chrome shafts before extreme winter storms demand full-width clearing capabilities.

This original equipment manufacturer hydraulic assembly features a robust, thick-walled black steel housing measuring 26-1/4 inches from end to end, providing a stable center-to-center pin distance of 26-1/2 inches when fully retracted. The cylinder incorporates a 1-inch hard-chromed piston rod to resist moisture pitting and sub-zero packing-gland freeze-ups, paired with a specialized external high-pressure fluid transfer tube running parallel to the main cylinder barrel. Utilizing a double-acting architecture, the cylinder routes dual high-pressure fluid streams directly to internal piston chambers through dual #6 SAE top ports. This configuration eliminates wing chatter and provides rigid hydraulic holding force against heavy roadside snowbanks.

For professional snow plowing contractors and utility shop supervisors, swapping out weather-checked or leaking wing rams eliminates internal fluid bypass and pump reservoir contamination. This factory-genuine component directly replaces older, discontinued structural part numbers B60347 and 43803, guaranteeing perfect mechanical clearance inside the slide-box tracking channels. Both ends of the cylinder are forged with precision-bored 5/8-inch bolt mounting holes to establish a tight mechanical lock with factory retention pins, ensuring zero slop during high-speed highway tracking or heavy-volume commercial stacking passes.

Benefits of the Western 77475 Ram Assembly

• Genuine OEM Replacement: Tailored and balanced to factory engineering blueprints to directly replace older part numbers B60347 and 43803.

• Double-Acting Hydraulic Architecture: Direct dual-port fluid routing delivers positive hydraulic pressure for both wing extension and retraction cycles.

• Premium Hard-Chromed Piston: High-polish 1-inch chrome rod minimizes seal friction and resists pitting to block water from infiltrating the hydraulic fluid pump reservoir.

• Flawless Fit Clearance: Built with a precise 13-15/16 inch stroke and a 26-1/2 inch retracted pin center to operate smoothly inside power slide boxes.

• Complete Exterior Fluid Tube: Features a factory-welded external steel fluid transfer tube to optimize pressure balance and eliminate internal fluid blockages.
