PGU QY25K5S 803100937

Product Introduction

This 803100937 PGU clutch booster is a complete air-assisted clutch servo assembly specially designed for XCMG QY25K5S truck crane. It works with the vehicle’s air brake system to amplify the force from the clutch pedal, reducing driver operation effort and delivering stable, responsive clutch engagement and disengagement. The package includes the main booster body and matching adjustable push rod for direct assembly.

The valve body is made of high-strength cast aluminum with precision internal air valve structure, ensuring sensitive air intake and exhaust control. The cylinder shell adopts anti-corrosion surface coating to resist rust under variable temperature and humid working environments. The rubber dust boot protects the internal piston assembly from dust, mud and water intrusion, lowering wear risk. The adjustable push rod allows fine-tuning of stroke and clearance during installation. All mounting holes and air port specifications follow OEM standards for straightforward replacement on QY25K5S crane.

Manufactured strictly in accordance with OEM dimensional standards, this clutch booster assembly can directly replace original spare parts without modification. We supply OEM equivalent and premium aftermarket quality grades. Every finished unit undergoes air tightness and stroke performance testing before shipment. Export-grade packaging and complete customs documents are available for overseas construction machinery repair shops and equipment distributors.
