FAW Jiefang Hydraulic Pneumatic Clutch System PartsJ6 Clutch Servo Assembly 1602305A70AB

The 1602305A70AB Clutch Servo Assembly is an important component of the FAW Jiefang heavy-duty truck clutch control system, designed to amplify the driver's clutch control force through a combination of hydraulic and pneumatic operation. When the clutch pedal is pressed, hydraulic fluid is used to initiate the control process, while compressed air provides additional force through the servo mechanism and transfers the amplified output to the clutch release system. This arrangement reduces the amount of pedal force required from the driver and supports smoother clutch disengagement during gear shifting. The clutch servo works together with the clutch master cylinder, hydraulic pipeline, vehicle compressed-air system, clutch release fork, and release bearing to complete the clutch operating cycle. The available technical reference for 1602305A70AB identifies it with FAW and specifies a corresponding clutch-servo configuration. For heavy-duty trucks used in long-distance transportation, logistics, construction, and other demanding operating environments, the clutch control system is subjected to frequent operating cycles. The 1602305A70AB servo assembly helps provide pneumatic assistance during clutch operation, allowing the release mechanism to receive the required operating force while reducing direct pedal effort. The corresponding technical data lists an 85 mm stroke, 130 mm mounting-hole spacing, 10 bar maximum operating pressure, and brake fluid SAE J1703 as the specified medium for the referenced clutch servo configuration. The assembly has a length of approximately 409–410 mm and a reference weight of approximately 2.7–2.9 kg, depending on the specific configuration. When purchasing, buyers should verify the part number, truck model, transmission configuration, mounting-hole spacing, pneumatic ports, hydraulic connections, and original assembly dimensions to ensure correct matching.
