Shaanxi Euro 5 Clutch Master Cylinder DZ93189230090

OE Number: DZ93189230090

Application: Shaanxi Delong Euro 5 heavy-duty trucks

Function: Converts pedal mechanical force into hydraulic pressure to operate the clutch slave cylinder for smooth shifting.

Key Features & Benefits

Direct Replacement: OEM-standard dimensions, oil ports, and interfaces ensure a plug-and-play fit.

Durable Build: High-strength aluminum alloy shell with high-precision sealing components.

Reliability: Resistant to wear, pressure, and aging for stable performance under heavy-duty conditions.

Fault Prevention: Resolves hydraulic leaks, soft pedals, difficult gear shifting, and incomplete clutch separation.

① Applicable Vehicle Models

Suitable for the Shaanxi Delong Euro 5 heavy‑duty truck series, including long‑haul logistics tractors, bulk cargo transport vehicles, engineering dump trucks, and urban freight trucks. Widely used for after‑sales replacement and maintenance, fleet overhaul, and spare parts procurement.

② System Compatibility

Belongs to the Shaanxi truck transmission system (clutch hydraulic components subcategory). It precisely matches the Euro 5 standard clutch hydraulic pipeline, pedal transmission mechanism, and clutch slave cylinder assembly. Fits the original mounting cavity perfectly without drilling, cutting, or structural modification. No additional calibration needed-ready for direct plug-and-play installation.

③ OEM Reference Number

Corresponding OE Number: DZ93189230090. All products are manufactured strictly according to original factory technical drawings and mold standards, achieving 100% dimensional consistency and direct interchangeability with the genuine OEM clutch master cylinder.

④ Interchangeability

Produced in full compliance with OEM dimensional and performance criteria. Core parameters-including overall installation dimensions, oil port specifications, hydraulic pressure ratings, internal sealing precision, and pedal travel matching sizes-are completely consistent with the original part. It directly replaces the factory clutch master cylinder, significantly reducing installation time and labor costs.

⑤ Additional Services

We offer professional compatibility verification based on your Shaanxi truck's model year, Euro 5 emission configuration, and specific clutch system symptoms. Additionally, we provide step-by-step disassembly and installation guidance, as well as recommended matching clutch hydraulic accessories. Our technical team offers end-to-end support to prevent issues such as hydraulic leaks, delayed clutch response, incomplete separation, and shifting failures caused by mismatched parts or improper installation.

Cylinder Body: High-strength die-cast aluminum alloy resistant to pressure, impacts, and chassis vibration.

Piston Assembly: Precision-machined for low friction, fast response, and stable pressure output.

Push Rod: High-hardness, wear-resistant steel designed for high fatigue resistance under frequent operation.

Seals: Multi-layer, oil-resistant rubber composite rings preventing internal and external hydraulic leaks.

Key Advantage: Built for heavy-truck harsh conditions-resistant to continuous pressure changes, road vibration, and hydraulic fluid corrosion.

The cylinder shell adopts anti-rust passivation and oil-proof anti-corrosion coating to resist moisture, dust and muddy water, avoiding long-term oxidation and peeling. The internal hydraulic passages are finely polished to lower hydraulic resistance, reduce seal wear and ensure stable pressure transmission. Precision-machined mounting surfaces enable tight installation and prevent oil seepage and air intake. The piston inner wall adopts high-precision honing for smooth, jamming-free operation and sensitive clutch response. Standard-tolerance seal grooves ensure tight seal fitting, minimize pressure loss and prolong service life.

The cylinder housing casting, piston precision machining, push rod, and sealing assembly are completed using advanced, fully automatic CNC equipment. Core procedures are carried out in a constant-temperature, dust-free workshop to eliminate internal stress and prevent structural deformation or hydraulic pressure instability.

Key indicators-including overall dimensional tolerance, hydraulic tightness, piston operating accuracy, and sealing stability-are inspected piece by piece using professional precision instruments. All finished products undergo a 100% full delivery inspection, including appearance defect detection, static and dynamic hydraulic leakage tests, and long-cycle reciprocating durability tests. Each batch is strictly screened according to OEM standards to meet the heavy-load and long-life working requirements of Shaanxi Euro 5 clutch hydraulic systems.

Equipped with specialized hydraulic clutch production lines and comprehensive testing facilities, we maintain standardized and reliable manufacturing processes. Our high monthly capacity and extensive inventory support bulk wholesale, immediate dispatch, and global export.
We also offer tailored services, including OEM branding, neutral packaging, custom surface treatments, and sample manufacturing, catering to the specific needs of auto parts distributors, repair shops, and fleet managers worldwide.

Q: Compared with ordinary aftermarket clutch master cylinders, what core advantages does this DZ93189230090 clutch master cylinder have?
