RITO PVD-2B-42L3DS-7S PVD-2B-42L Hydraulic Main Pump KX161-3 KX155 U45 U55 Excavator Piston Pump Oil Pump Assembly

Hydraulic failure on construction sites leads to expensive downtime and missed deadlines. The PVK-2B-505-YYB Main Pump Assembly addresses these pain points by offering stable, high-pressure output. Perfectly compatible with 5-ton series excavators, it ensures smooth, powerful operations.

Excavation fleets often face weak torque output, track slipping, and final drive failure under heavy mining load cycles, leading to costly downtime and reduced productivity.

Hydraulic performance on aging EX series machines often drops due to internal leakage and unstable pressure control. RITO 4191115 EX100WD HPV050 Main Hydraulic Pump Assembly is developed to bring back original working balance for EX100-2 and EX100WD excavators used in earthmoving and site preparation.

Losing track tracking power or climbing torque on your mini excavator? A failing CAT305 final drive slows down trenching and urban landscaping jobs. Internal oil leaks or worn travel gears quickly cause total track lockups, stranding your 305CCR or 305.5 on site and running up expensive towing costs.

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.

Slow boom lifting and stalling engines on your PC100-5 mean internal piston wear. When your main pump loses pressure, the entire machine loses its hydraulic speed, hurting your quarry performance.

Losing final drive gear oil into your travel motor compartment or fighting constant fluid weeping around your high-pressure hydraulic block joints? Standard O-rings with round cross-sections can easily twist or roll inside deep structural grooves under extreme cyclic pressure spikes, leading to immediate seal extrusion and total fluid loss. Seal your heavy-duty mechanical junctions completely by deploying the high-rigidity RITO 096-8058 rectangular seal immediately.

Unstable hydraulic pressure causes sluggish operation and costly pump damage for mines. Low-grade valves leak or fail under high-stress cycles, halting production. The 4674564 / 4469379 ensures peak pressure stability. This Main Relief Valve for ZX450 offers zero-leakage precision.
