Product Descriptio

This AP2D36 variable plunger hydraulic pump is a dedicated main hydraulic pump for Deere 75C and 80C medium-sized excavators. The part number corresponds to 4472052 and 4437197. The model specification is AP2D36LV1RS6-909-4. As the core assembly of the entire machine's hydraulic power, it integrates the main variable plunger pump and the pilot gear pump into a single unit. It perfectly matches the installation dimensions, oil port layout and power output parameters of the hydraulic system of 75C and 80C models. Without the need to modify the pipelines and brackets, it can directly replace the original pump body. It is an excellent supporting accessory for equipment major repairs and old pump replacements.

The pump body shell is precision cast from high-strength cast steel and undergoes aging stress relief treatment. Under heavy-load and impact working conditions such as earth excavation, breaker hammer operation, and muddy construction sites, it can effectively resist vibrations and high-pressure impacts, reducing the risks of shell cracking and leakage. The internal components such as the plunger, cylinder, and flow distributor plate, made of high-maintenance alloy materials, are combined with precise grinding processing technology. This ensures stable oil film under high pressure, significantly reduces internal leakage, and maintains the pump's output flow and pressure stability for a long time. This fundamentally solves common hydraulic faults such as slow operation, lack of power, stuck vehicle, and overheating in excavators.
