Shacman Heavy Truck Clutch Booster & Assist Cylinder DZ9112230178

The DZ9112230178 Clutch Booster Cylinder plays a fundamental role in improving driver ergonomics and drivetrain performance. By combining hydraulic pressure from the foot pedal with auxiliary air pressure from the chassis pneumatic system, this Shacman clutch servo drastically reduces driver pedal effort required to disengage heavy 430mm clutch pressure plates.

Manufactured in ISO9001-certified facilities using precision-machined aluminum housing, wear-resistant internal rubber seals, and high-tensile actuator pistons, the DZ9112230178 cylinder delivers linear force output and fast response times under intense operating loads. Replacing a leaking, sticking, or pressure-losing clutch booster with a brand-new DZ9112230178 unit eliminates stiff pedal action, prevents incomplete clutch disengagement, and protects transmission gears from wear during shifts.

Technical Specifications

Key Features and Benefits

• Air-Assisted Effort Reduction: Amplifies driver foot pressure via compressed air assistance, significantly reducing pedal effort during frequent gear changes.

• Corrosion-Resistant Cast Body: Lightweight, durable cast aluminum housing effectively resists internal hydraulic corrosion and external moisture damage.

• Precision Air and Oil Sealing: High-grade elastomeric piston seals prevent hydraulic fluid leaks and compressed air bypass for consistent pedal feedback.

• Direct OEM Fitment: Manufactured strictly according to original specification DZ9112230178 for exact hydraulic line, air line, and pushrod alignment on Shacman chassis.

Compatible Vehicle Applications

This DZ9112230178 clutch assist cylinder is engineered for heavy transport platforms:

• Shacman Truck Series: Shacman Delong X3000, F3000, H3000, and M3000 heavy dumpers, tractor units, concrete mixers, and long-distance cargo trucks.

Symptoms of a Failed Clutch Booster Cylinder

Fleet mechanics and operators should inspect or replace the DZ9112230178 clutch booster when observing:

• Exceptionally hard or stiff clutch pedal resistance requiring excessive driver leg effort.

• Hydraulic fluid leaking from the booster pushrod dust boot or air exhaust port.

• Air leaking continuously from the booster exhaust valve when the clutch pedal is depressed or released.

• Spongy pedal feel, incomplete clutch disengagement, or gear grinding during shifting.

Packaging and Delivery Details

• Protective Export Packaging: Individually packed in a durable export carton with protective port plugs to keep internal hydraulic passages clean and dust-free during transit.

• Fast Lead Time: Short order fulfillment within 3 to 7 working days via international air courier, air cargo, or ocean shipping.

• Flexible Order Support: Low MOQ of 1 piece supported by secure T/T payment terms.

Frequently Asked Questions (FAQ)

Q1: What is the primary function of the DZ9112230178 clutch booster on Shacman trucks?

A: It uses compressed air from the truck's air system to assist hydraulic pressure from the master cylinder, making it easy for drivers to press the clutch pedal.

Q2: Can air in the hydraulic line cause the clutch booster to malfunction?

A: Yes, air trapped in the hydraulic actuation fluid will cause a soft, spongy pedal feel and poor booster responsiveness; the hydraulic system should be thoroughly bled when installing a new booster.
