gear box oil pump

1. Testing & Quality Control Process Full Disassembly & Inspection : The pump is completely disassembled, and all components are inspected for wear, damage, and defects. Deep Cleaning : All components are cleaned to remove debris, sludge, and contaminants. Component Replacement : Worn gears, bearings, and seals are replaced with high-quality replacement parts. Assembly & Pressure Testing : The pump is reassembled and tested for pressure output, flow rate, and performance

1. Product Overview This is a brand-new CVT transmission oil pump assembly , OE part number 025CHA1506400 , designed for the Chery QR025 series / CVT250 CVT transmissions . It is compatible with Chery Tiggo 4, Tiggo 7, and Tiggo 8 models equipped with QR025HCA, QR025CHB, QR025CHC, 025CHA, or 0CF25A CVT transmissions. As the heart of the transmission’s hydraulic system, this oil pump generates pressure to circulate fluid throughout the gearbox, lubricating components, cooling

Typical Faults: Rotor/Gear Wear Symptom: Low line pressure (P0841/P0868 codes, delayed shifts) Cause: Contaminated ATF or metal debris scoring surfaces Seal Failure Symptom: Pressure loss at idle (pump whine) Trigger: Hardened/rolled seals from heat/age Cavitation Damage Symptom: Foamy ATF, erratic shifts Root Cause: Clogged filter or aerated fluid Critical Checks: Clearance: Rotor-to-housing >0.15mm = replace Prime Test: Should generate 20+ psi instantly at crank Debris

1. Product Overview This is a professionally remanufactured CVT transmission oil pump , OE part number 4815002400 , designed for the Hyundai C0GF1 CVT transmission . It is compatible with Hyundai Accent models from 2017 to 2023, including 1.4L, 1.5L, 1.8L, and 2.0L engine variants. The oil pump is the heart of the CVT transmission, providing the necessary hydraulic pressure to operate clutches, maintain belt tension, and lubricate all moving components. This unit has been

Function: Generates hydraulic pressure (80-150 psi) to actuate clutches, lubricate components, and cool the transmission. Driven by the torque converter or input shaft. Key Components: Gear Types: Gerotor (most common), crescent, or vane pump designs. Critical Parts: Pump housing, inner/outer rotors, pressure relief valve, and seals. Failure Modes: Wear: Contaminated ATF causes rotor scoring (low pressure → P0841/P0868 codes). Cavitation: Air ingestion from clogged filter

Function: High-pressure hydraulic supply (25–120 psi) for clutch actuation and lubrication in Ford RWD applications. Design: Variable-displacement vane pump (12-vane rotor, hardened steel housing) Electronic pressure control valve (PWM-regulated flow) Key Specs: Flow rate: 18–22 L/min @ 2500 RPM Clearance: 0.02–0.05mm vane-to-cam (replace if >0.12mm) Relief valve setting: 135±5 psi Failure Modes: Vane sticking (debris or fluid oxidation) Pressure sensor drift (causing shift
