Ultra-High-Pressure Reinforced Construction: The BY612600081470 assembly features a specialized multi-layer hose with a synthetic rubber inner tube, multiple steel wire braid reinforcements, and a rugged outer cover, engineered to contain fuel pressures exceeding 1500-2000 bar without bursting or swelling.
Precision Swaged Fittings: Equipped with permanently attached, high-precision steel fittings that are crimped (swaged) onto the hose ends under immense force. This creates a leak-proof, permanent connection that is far more reliable than clamp-on fittings for high-pressure applications.
Superior Fuel and Abrasion Resistance: The inner tube material is specifically compounded to resist modern ultra-low-sulfur diesel (ULSD) and biodiesel blends, preventing degradation. The tough outer cover protects against abrasion from contact with other engine components.
Optimized Flow and Pulse Dampening: Designed with a smooth internal bore to minimize flow restriction and pressure drop. The hose’s inherent flexibility also helps absorb minor pressure pulses from the injection pump, contributing to smoother injector operation.

Always verify the exact specifications of BY612600081470 for your engine. Using a hose rated for lower pressure can lead to catastrophic failure.
The BY612600081470 assembly forms part of the high-pressure fuel circuit in common rail or unit injector diesel systems. It transports pressurized fuel from the outlet of the injection pump to the common rail or directly to individual injectors.
Its primary function is to contain and convey fuel at extremely high pressures without expanding, leaking, or failing. This ensures that the precise volume of fuel metered by the pump reaches the injection point with minimal pressure loss.
Any weakness in this hose, such as a slight seepage or bulge, can cause a significant drop in rail pressure. This leads to engine misfires, reduced power, poor fuel economy, and increased hydrocarbon emissions.
For technicians, the BY612600081470 is a safety-critical component. Its failure while the engine is running can result in a high-pressure fuel spray, which is a severe fire hazard and can cause immediate engine shutdown.
1. Depressurize the fuel system completely. Refer to the service manual for the correct procedure, which often involves disabling the fuel pump and cracking a low-pressure connection.
2. Disconnect the vehicle battery to eliminate any risk of sparks near fuel components during the repair.
3. Carefully clean the area around the old hose connections to prevent dirt from entering the high-pressure system.
4. Use proper line wrenches to loosen and remove the old BY612600081470 assembly. Note the routing and any securing clips.
5. Compare the new assembly with the old one. Ensure the fittings, length, and hose curvature are identical.
6. Install the new assembly by hand-tightening the fittings first to avoid cross-threading, then torque to the manufacturer’s specification using a calibrated torque wrench.
7. Reconnect the battery, prime the low-pressure system, start the engine, and use a diagnostic tool to monitor rail pressure while checking for leaks with a mirror and light.
• Inspect the BY612600081470 hose assembly visually during every major service interval. Look for signs of wetness, fuel stains, abrasion, cracks, or bulging in the hose body.
• Check for a strong smell of diesel in the engine bay, which could indicate a micro-leak not visible to the eye.
• Ensure the hose is not touching hot surfaces like the exhaust manifold and is securely held by all factory brackets to prevent vibration-induced wear.
• High-pressure fuel hoses have a recommended service life (e.g., 5-7 years). Proactive replacement based on age is often wiser than waiting for failure.
• Never attempt to repair a high-pressure fuel hose with tape, clamps, or splicing. Always replace the entire assembly with a genuine part like BY612600081470.
• Keep detailed service records, including the date of high-pressure hose replacement, for safety compliance and future maintenance planning.
Safety is paramount when working with the high-pressure fuel system. Always wear safety glasses and gloves. Never use your hands to check for leaks while the engine is running; use appropriate tools.
Choosing the genuine BY612600081470 assembly guarantees material integrity, pressure rating certification, and perfect fitment that generic or “will-fit” hoses cannot reliably provide. SHACMAN sources hoses that meet or exceed the specific demands of their engine’s pressure profiles.
Aftermarket hoses may claim similar pressure ratings but often lack the consistent quality control in the crimping process. A poorly crimped fitting is the most common point of failure under high pressure.
The genuine BY612600081470 is tested as a complete unit, ensuring the hose and fittings work together seamlessly under pulsating pressure cycles. This validation is crucial for component longevity and safety.
Using the OEM part ensures the fuel system’s hydraulic performance remains as engineered, maintaining emission compliance, engine warranty, and most importantly, operator safety.
Master technicians stress that the high-pressure fuel system is no place for compromises. The BY612600081470 is recognized for its precise length and fitting angles, which prevent stress on connections during engine movement.
Fleet managers who standardize on genuine high-pressure components report a dramatic reduction in roadside failures related to fuel system issues. This reliability is a direct contributor to lower total operating costs.
Operators note that after replacing aged hoses with a new BY612600081470, engines often run smoother and more consistently, as optimal rail pressure is restored and maintained.
The BY612600081470 plays a direct role in workshop and vehicle safety. A failed high-pressure hose can spray fuel with enough force to penetrate skin, requiring immediate medical attention, and can easily ignite on hot engine parts.
Environmentally, a leak from this assembly releases raw fuel directly into the engine bay and onto the road, causing pollution. A secure, genuine hose minimizes this risk.
By ensuring complete combustion through maintained injection pressure, the BY612600081470 also helps the engine meet its designed emission levels, contributing to cleaner air.
Every BY612600081470 assembly is manufactured under strict quality standards. Each hose is typically batch-tested to withstand burst pressures far exceeding its rated working pressure.
The crimping process is automated and monitored to ensure every fitting connection achieves the required pull-off force and pressure seal. This level of consistency is the hallmark of a genuine SHACMAN part.
Purchasing the BY612600081470 from authorized channels provides traceability and the assurance that the component meets all relevant automotive safety and material specifications.
The cost of a genuine BY612600081470 is minor compared to the potential consequences of failure. These include tow truck fees, expensive engine diagnostics, potential fire damage, and significant vehicle downtime.
For fleets, a single roadside failure can wipe out the savings from using dozens of non-genuine hoses. The investment in proven reliability pays for itself in predictable maintenance and uptime.
Using the correct BY612600081470 assembly also protects other expensive components like the fuel injection pump and injectors from damage caused by pressure fluctuations or contamination from external leaks.
Always use the OEM number BY612600081470 when ordering. High-pressure hoses are not universal; differences in length by just a few centimeters or fitting thread pitch can render them unusable or dangerous.
Consult the SHACMAN electronic parts catalog (EPC) using your truck’s VIN. This is the only way to guarantee the correct hose assembly for your specific engine model and production year.
When in doubt, consult with a certified SHACMAN parts specialist who can confirm the exact application and provide the latest version of the part.
