RITO OEM Hydraulic Main Pump PSVL-42 Variable Displacement Axial Piston Pump Oil Pump Assembly for Excavator

Struggling with excavator downtime and costly hydraulic leaks? The Mag-33vXZZC Final Drive Assembly solves reliability issues in harsh mining environments. This heavy-duty travel motor offers seamless compatibility for R55, R60, and R80 models, ensuring peak torque and long-term durability.

Weak hydraulic pressure leads to slow cycles and dropped payloads. The RITO 208-1149 SBS80 main pump assembly delivers high-pressure fluid flow to restore standard working speeds. Engineered for 312B, 312C, 311B, and 311C heavy excavators.

Unexpected drive gear failure can paralyze your ZX200-3 excavator, leading to massive operational losses. The 3100993 Hydraulic Pump Shaft Gear is the definitive solution to transmission slippage and pump noise. It restores the vital connection between the engine and the HPV118 pump.

When excavators suffer from slow hydraulic response or unstable digging force, the main pump is often the core issue behind productivity loss. The RITO AP2D36L-LJZ hydraulic piston pump is developed to deliver stable oil pressure, efficient hydraulic transmission, and dependable machine performance for excavation, roadwork, and quarry operations.

When hydraulic output becomes unstable or actuator response feels inconsistent, the root cause is often internal swash plate wear that disrupts pump displacement control. 718438 swash plate assembly is engineered for high-capacity hydraulic systems used in Doosan DX300 and Volvo EC460B excavators, restoring accurate angle control and smooth variable displacement performance inside the main pump.

Struggling with hydraulic pressure loss or frequent downtime? Worn pump barrels lead to catastrophic system failure and costly project delays. Our 711701 cylinder block solves these inefficiencies, ensuring your DH225-7 or R215-7 maintains peak operational power.

Excessive friction between piston shoes and swash plates drops pump pressure, causing slow excavator response and heavy fuel losses. Weak slippers crush or split under violent hydraulic spikes. For fleet operations using SK200-6 or DH220 machines, one damaged shoe triggers widespread metal grinding, ruining expensive main pump rotating groups.

Swing motion problems on E315C / 315C / 318B / E315CHZZC excavators are often linked to internal torque loss inside the reduction unit rather than hydraulic pump failure. The RITO 199-4602 / 1994601 swing reduction motor is built to re-establish stable rotary drive transfer between the hydraulic system and the swing gearbox.
