Bezares PT3131PGE633RP 10-Bolt PTO

The 3131 Series is a 10-bolt, heavy-duty PTO designed to work with major transmissions (notably Allison models) and built for the most grueling service environments. It features high torque capability, internal lubrication to simplify installation, and a variety of gear ratio and output options to match different drive-pump requirements.

Key Features & Highlights

• High Torque Capacity: Maximum intermittent torque up to approximately 500 ft-lb with power rating up to ~97 HP at 1000 rpm for certain ratio configurations.
• Internal Lubrication: The 3131 Series uses internal lubrication (rather than relying only on transmission lubrication or an external hose) which reduces install complexity, helps cooler operation, and improves bearing life.
• Wide Ratio & Output Options: You’ll find internal gear ratios like ~0.50 (50 %), 0.58, 0.68, 0.78, 0.84, 0.97 (and more) depending on the unit. This flexibility allows the PTO’s output speed (and thus pump speed) to be matched to accessory demands.
• Robust Construction: The housing and flanges are reinforced and sized for heavy-duty applications. Larger bolts, better gasket/seal materials (e.g., Garlock® gasket, Viton® O-rings) are used to handle high loads and reduce leaks.
• Installation-Friendly Features: In addition to the internal lube system, the 3131 offers things like a rotatable solenoid cover (for clearance in tight chassis spaces) and includes many accessories (hoses, hardware, wiring) depending on configuration.
• Designed for Vocational Truck Use: Typical applications include large body-pump drives, rear pump outputs (rear-mount pump options called “3131RP”), dump trucks, vacuum trucks, heavy equipment installations.
