RITO Hydraulic Main Pump Assembly AP2D36L-LJZ AP2D36 Hydraulic Piston Pump for Excavator

Hydraulic instability in compact excavators causes jerky movements and project delays. The AP2V36LV1S7 Main Pump Assembly eliminates these performance gaps, providing smooth, high-precision power for VIO70 models. It is the essential solution for maintaining peak productivity in tight construction sites.

Hydraulic pump breakdown is often traced back to bearing fatigue long before obvious mechanical failure appears. RITO A10VD43SR Tapered Roller Bearing is developed for excavator main pump assemblies, supporting stable shaft rotation and reducing internal friction during continuous hydraulic operation.

Fluid leaks inside heavy travel and swing motors cause catastrophic torque loss, halting vital track movement instantly. When substandard oil seals harden and warp under high rotational friction, field operators face massive hydraulic oil waste, component scoring, and expensive project delays.

Designed for mid-size Hitachi excavation platforms, RITO 4288541 EX100M-3 HPV091 Hydraulic Main Pump delivers stable pressure output and smooth hydraulic response for EX100-3 and EX100M-3 series machines. The HPV091 axial piston structure helps maintain consistent flow balance during long-hour construction and earthmoving tasks. 

Unresponsive cylinder links and sudden power loss point directly to a degrading main piston pump. When internal cylinder blocks lose sealing clearances, your entire excavator circuit suffers severe pressure fade, slowing your project progress to a crawl. Stop letting an inefficient power plant destroy the productivity of your ZX200-3 or ZX210-3 excavators.

Are you struggling with rapid cylinder barrel tilt or constant internal rattling that destroys your hydraulic pump overhauls? When an uncalibrated spacer fails to hold the ball guide at the strict mechanical centerline, uneven shoe alignment quickly grinds down your rotating assemblies. Drop in the wear-resistant RITO 104166A ball guide spacer to establish a perfectly balanced interior linkage tracking height.

Large crawler excavators working in mining, quarrying, and heavy construction environments require a powerful travel system to handle continuous movement, high loads, and challenging ground conditions. Long-term operation under heavy workloads can place significant stress on hydraulic motors, planetary gears, and reduction mechanisms, which may result in weak travel force, slow crawler movement, abnormal noise, or reduced machine efficiency. 2401-9229A Travel Reduction Gearbox Assembly is developed for DH500 excavators, integrating with the hydraulic track drive motor system to provide reliable torque transmission and smooth crawler operation. Related references include 170402-00023, which is associated with DH500 / Solar 500LC-V travel gearbox and final drive applications.

Experiencing heavy structural vibration, grinding noises, or quick piston shoe failures inside your main hydraulic pump? When a worn cradle support gets pitted or distorted, the swash plate tilts unevenly, leading to rapid component scoring and expensive pump failures. Restore perfect variable stability using the high-precision RITO 321707 pump support bracket.
