Short Description
Heavy-duty aftermarket 107-8136 (CAT Reman: 10R-1140) Dual Axial Piston Variable Displacement Hydraulic Pump, engineered as a 100% precision interchangeable drop-in replacement for Caterpillar 320B, 320B L, and 320B N Excavators. Built to rigid OEM tolerances and cross-referenced with Bosch Rexroth/Daikin technology benchmarks [cite: Gemini Chat. Evidence: Sustained engagement and detailed technical discussions regarding a wide range of hydraulic products including Rexroth, Parker, Eaton, and Vickers series. Date: 2026-01 to 2026-06.], this master pump delivers powerful flow-matching capabilities, reliable heavy-trenching pressure retention, and extended structural lifespan.
Key Highlights
-
100% Accurate Bolt-On Configuration: Directly replaces Caterpillar factory part number 107-8136 and Reman assembly code 10R-1140. Spline shaft setups, suction/discharge flanges, and pilot connections align perfectly for zero field adjustments.
-
Dual-Pump Flow Management: Built on the rugged A8VO series base, the synchronized front and rear split-flow setup perfectly pairs with CAT 3066T engine outputs, preventing engine bog-down during demanding boom, stick, and bucket multi-functioning.
-
Premium Hardened Core Components: Enhanced with micro-finished valve plates, heavy-duty piston shoes, bimetal cylinder blocks, and certified high-pressure shafts to withstand maximum relief pressure margins in tough demolition or rock-handling duties.
-
Factory Direct B2B Pricing: Ideal option for international machinery parts wholesalers and premium hydraulic repair networks seeking to bypass heavy OEM distribution markups while maintaining high operational uptime.

FAQ
Q1: Can this 107-8136 replacement pump fit if my excavator tag displays Reman code 10R-1140? A: Yes, perfectly. 10R-1140 is the official Caterpillar designated part code for remanufactured alternatives of the new 107-8136 main pump group. Our premium aftermarket assembly aligns with both codes identically, ensuring exact matching of standard mounting pilots, splines, and regulators.
Q2: Is this pump assembly shipped fully tuned and ready for field excavation? A: Absolutely. Prior to wooden crate packing, every single 107-8136 dual pump undergoes thorough dynamic testing on our heavy hydraulic test benches. Regulators and flow control responses are preset to standard CAT 320B operational flow curves, making it an immediate drop-in solution out of the box.
