Original Zexel Nozzles105017-3460 Diesel Nozzles Injector Nozzles Dlla145pn346

Product Details

Product Overview

This high-quality diesel injector nozzle, identified by the OEM part number 105017-3460 and model DLLA145PN346, is a genuine Zexel component designed for precision fuel injection systems. As a critical element of the engine’s fuel delivery system, this nozzle ensures optimal atomization of diesel fuel, directly impacting combustion efficiency and engine performance.

Specifically engineered for Isuzu diesel engines, this nozzle is a direct replacement for applications commonly found in the Isuzu 6HH1 engine platform, frequently used in the NPR series of medium-duty trucks. While fitment is primarily associated with these models, it may also be compatible with other Isuzu industrial and automotive engines from the 1976-1993 era. Always verify compatibility with your specific engine code before purchase.

FAQ

Q1: How can I confirm this nozzle (105017-3460 / DLLA145PN346) fits my Isuzu engine?
A: The most reliable method is to check your engine’s identification plate for the Engine Code. This nozzle is specifically designed for the Isuzu 6HH1 engine. You should also remove your old nozzle and visually compare the model number stamped on its body (it should read DLLA145PN346). If the engine code and nozzle model match, the fitment is guaranteed.

Q2: What is the recommended installation procedure for a diesel injector nozzle?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the nozzle bore in the cylinder head. 2) Replacing the copper washer (heat shield) under the nozzle. 3) Tightening the nozzle clamp or retaining nut to the manufacturer’s specified torque to avoid distortion. 4) Ensuring the high-pressure fuel line is clean and properly seated. Improper installation can lead to injector failure or engine damage.

Q3: What maintenance is required for these nozzles, and how long do they typically last?
A: Diesel injector nozzles do not require routine maintenance but are a wear item. Their lifespan depends on fuel quality, engine operating conditions, and maintenance of the fuel system (filters). Typically, a high-quality Zexel nozzle can last between 100,000 to 200,000 miles (or 3,000 to 5,000 operating hours) in a well-maintained engine. Signs of wear include hard starting, black smoke, rough idling, and decreased fuel economy. We recommend replacing nozzles in complete sets (all cylinders) for balanced engine performance.
