Description
Product Brief Introduction


This is a VIE heavy-duty pneumatic clutch booster with 102mm cylinder bore, part number 21350200030-MY. It is professionally designed for heavy-duty passenger buses, widely suitable for city buses and tour coaches. Adopting mature pneumatic assist technology, the product features stable output power, sensitive response and strong durability, which perfectly matches the original OEM assembly standards of mainstream bus models.

Product Usage

The clutch booster is a core auxiliary component of the vehicle clutch control system. It takes compressed air as the power medium to provide auxiliary thrust for the clutch hydraulic system. It effectively reduces the driver’s pedal operating force, realizes light and smooth clutch separation and combination, and ensures stable and accurate gear shifting. It is mainly used for daily driving, frequent start-stop and long-distance transportation of heavy-duty passenger buses, improving driving comfort and reducing driving fatigue.

Product Features

1. First, it adopts a standard 102mm large cylinder bore design, with strong bearing capacity and stable power output, meeting the high-load working requirements of heavy buses.
2. Second, the integrated structure of aluminum alloy valve body and high-strength steel cylinder realizes light weight, high rigidity and anti-deformation performance.
3. Third, it is equipped with an adjustable threaded push rod and locking nut, which can fine-tune the stroke to adapt to different assembly gaps of bus chassis.
4. Fourth, the integrated rubber dustproof cover effectively blocks dust, sediment and moisture, preventing internal air leakage and component abrasion.
5. Fifth, dual air inlet ports ensure sufficient and stable air intake, with sensitive and rapid response.
6. Sixth, all products pass 100% air tightness and pressure tests before delivery, with consistent quality and low failure rate.


Product Advantages


In terms of compatibility, this model fully conforms to OEM parameters and is highly compatible with city buses and tour coaches, with no modification required during replacement. In terms of performance, the pneumatic assist is powerful and uniform, solving the problems of heavy clutch pedal, slow separation and difficult gear shifting of heavy-duty vehicles. In terms of durability, the precision sealing structure and high-quality wear-resistant accessories extend the service life and reduce frequent maintenance costs. In terms of safety, stable air pressure output avoids clutch jamming and slipping, ensuring driving safety during long-term and high-frequency operation. In terms of cost performance, it features stable quality, long service cycle and competitive aftermarket replacement cost.

Installation Steps

1. Prepare tools and cut off the vehicle air source and power supply, release the residual air pressure in the pneumatic system to ensure safe operation.
2. Remove the old clutch booster, disconnect the air inlet pipeline and hydraulic pipeline, and clean the pipeline interface to avoid dust and impurities entering the system.
3. Align the mounting flange of the new VIE clutch booster with the chassis mounting position, fix the bolts symmetrically and tighten them to the standard torque to avoid deviation and vibration.
4. Connect the air inlet pipeline and hydraulic pipeline correctly, install protective caps on the air ports, and ensure all interfaces are sealed firmly without looseness.
5. Adjust the length of the push rod and lock the nut, calibrate the clutch stroke to ensure complete separation and tight combination of the clutch.
6. Restore the vehicle air source, start the engine, step on the clutch pedal repeatedly for test, check for air leakage, oil leakage and abnormal jitter.
7. Test the gear shifting operation under idle and low-speed conditions, confirm the clutch works smoothly, and complete the installation.
Installation & Operation Precautions

1. Professional maintenance personnel are required for installation; non-standard disassembly and installation will cause air leakage and functional failure.
2. Strictly confirm the part number 21350200030-MY and 102mm cylinder bore before installation to avoid model mismatch affecting assembly and use.
3. Keep the pipeline interfaces clean during installation; prohibit sundries from entering the air channel and hydraulic channel to prevent pipeline blockage and component damage.
4. Do not over-tighten or loosely install the fixing bolts; asymmetric bolt force will cause shell deformation and air leakage.
5. The push rod adjustment shall comply with the standard stroke; excessive stroke will cause clutch ablation, and insufficient stroke will lead to incomplete separation.
6. Regularly check the air tightness of the pipeline and the aging degree of the dust cover during daily use, and replace vulnerable parts in time.
7. Keep the working air pressure within the standard range of 0.6–0.8MPa; over-pressure operation will damage the internal sealing components.
8. In case of clutch weakness, slow response or air leakage, stop using and inspect immediately to avoid driving safety hazards.
