AZ1560130070 Howo WD615 Single-cylinder Air Compressor

AZ1560130070 is a single-cylinder air compressor for HOWO WD615 heavy-duty trucks. As a key component of the air brake and auxiliary air systems, it supplies stable compressed air for braking and drives the engine oil pump. With 6 years of market validation and over 40 customers, it features stable performance, no cylinder wear, air leakage, abnormal noise or pressure fluctuations.

With 6 years of market validation and over 40 fleet/repair shop customers, this compressor delivers consistent, trouble-free performance. It features a compact single-cylinder piston water-cooled structure: a 2mm high-phosphorus cast iron dry liner with a reticulated inner surface for enhanced lubrication and wear resistance, paired with a heat-treated, nitrided crankshaft for long-term durability.

Designed for heavy-duty operation, it performs reliably in -30°C to 120°C extreme temperatures, resists vibration and oil/coolant corrosion, and maintains stable output under continuous use. Its optimized design ensures efficient air compression, with a 636cc/min displacement that fully meets the vehicle's air demand.

It is a direct-fit replacement for HOWO WD615's original engine and transmission, perfectly matching the factory flange and coupling for bolt-on installation with no modifications required. Every unit undergoes rigorous testing for airtightness, pressure capacity, wear resistance, and fatigue life (2 million cycles) to guarantee long-term reliability.

① Premium Durability & Consistent PerformanceHigh-phosphorus cast iron liner and nitrided crankshaft deliver exceptional wear resistance, ensuring stable air pressure, zero leakage, and reliable brake response even after long hours of heavy-duty operation.

② High Efficiency & Energy SavingsOptimized single-cylinder design enables fast, efficient compression with low power consumption, while the 636cc/min displacement fully satisfies the vehicle's brake and auxiliary air system requirements.

③ Extreme Environment AdaptabilityWater-cooled structure maintains optimal operating temperature, while robust construction resists vibration, corrosion, and extreme temperatures (-30°C to 120°C), making it ideal for heavy-duty truck operating conditions.

④ Direct-Fit for HOWO WD615, Easy InstallationPrecisely matches the original flange size and transmission mode for bolt-on installation. No drilling, cutting, or adjustments needed, cutting maintenance time by 40% and reducing downtime.

Only for HOWO trucks with WD615 diesel engines. No HOWO T7H, FAW J6, SHACMAN F3000-different structures cause air leakage, insufficient pressure, or brake failure, unsafe.

Product Model: AZ1560130070

Fits vehicles: HOWO WD615 series trucks

Function: Generates compressed air for brakes; drives engine oil pump

Material: Cylinder liner (high-phosphorus cast iron); crankshaft (heat-treated alloy steel)

Installation: Flange + coupled drive, fits original parts

Working conditions: -30℃ to 120℃; continuous operation; resists vibration, oil/coolant corrosion

Key specs: Single-cylinder water-cooled; 636cc/min displacement; ≤0.05MPa leakage per minute

Q1: Fits HOWO T7H, FAW J6, or SHACMAN F3000?

A1: No, only HOWO with WD615 engines.

Q2: Insufficient pressure, air leakage, or abnormal noise?

A2: Check bolt torque first, then liner/seal and coupling alignment. Still bad? Contact us.

Q3: How to maintain?

A3: Inspect every 25,000km; replace liner and seal every 4 years/300,000km; maintain cooling and lubrication systems.

Q4: Tools for install?

A4: Torque wrench recommended. Takes 2-2.5 hours with basic engine knowledge; shut down engine and release air pressure before disassembly.
