Foton Auman Truck GTL EST Spare Parts Clutch Master Cylinder with Oil Port H4163030000A0 Clutch Master Cylinder with Reservoir

• This clutch master cylinder assembly is engineered as a direct original equipment manufacturer (OEM) replacement part for heavy-duty commercial trucks, primarily utilized on:

  • Foton Auman Trucks: Standard clutch hydraulic system component for heavy-duty platforms including Auman GTL, EST, and G-series tractors, rigid cargo carriers, and tippers.

  • Heavy Commercial Fleet Platforms: Tailored for heavy truck manual or automated-manual transmission configurations requiring the matching chassis hydraulic control layout (part number: H4163030000A0).

• Integrated Fluid Reservoir Design: Features a built-in, heavy-duty translucent fluid tank that simplifies under-hood installation, prevents external hose leaks, and allows easy fluid level monitoring.

• High-Pressure Hydraulic Sealing: Equipped with premium, wear-resistant internal rubber pistons and seals designed to withstand high hydraulic cycling pressure without leakage or pressure drops.

• Precise Fluid Metering: Engineerd with strict mechanical tolerances to deliver consistent pedal feel, smooth stroke progression, and immediate clutch response.

• Corrosion-Resistant Housing: Manufactured from high-strength treated alloy casting or industrial composites to resist aggressive brake/clutch fluids, moisture, and engine bay heat.

When replacing the H4163030000A0 clutch master cylinder due to internal seal bypass, fluid leakage, or a spongy pedal, inspecting the following adjacent hydraulic and clutch components is highly recommended:

• Clutch Slave Cylinder / Booster: Located downstream at the transmission bell housing; if the master cylinder fails due to fluid contamination, the slave cylinder or clutch booster often requires simultaneous inspection or replacement.

• Hydraulic Clutch Lines & Hoses: High-pressure hoses linking the master cylinder to the booster; old hoses must be checked for cracking, expansion under pressure, or weeping.

• Premium Brake/Clutch Fluid: The system must be thoroughly flushed and refilled with fresh, manufacturer-specified DOT 3 or DOT 4 fluid to remove old metallic debris and moisture.

• Clutch Pedal Return Spring & Clevis Pin: The mechanical linkage hardware connecting the pedal arm to the master cylinder pushrod; ensure the pin is greased and not elongated.
