Product Details
Fuel Injector Nozzle 105017-3260
,DLLA136PN326 for ISUZU 4JH1
,OEM Replacement Fuel Injector
The Diesel Fuel Injector Nozzle with part numbers 105017-3260 and DLLA136PN326 is a direct-fit replacement for ISUZU 4JH1 diesel engines (also listed for 4HK1 applications). Installed inside the injector body, this nozzle atomizes diesel fuel into a fine mist for combustion, directly affecting engine power, fuel economy, and emissions.
Pressurized fuel from the common rail enters the nozzle body and lifts the needle valve against spring pressure. Fuel exits through precision-drilled holes (6 holes, 0.135 mm diameter) at a 136° spray cone angle, creating a fine mist that mixes with intake air for efficient combustion. Worn or clogged nozzles cause poor atomization, leading to rough idle, power loss, and increased smoke.
- VerifiedFitment Verified: Multiple supplier catalogs list 105017-3260 / DLLA136PN326 for ISUZU 4JH1.
- VerifiedTechnical Specs Verified (Aftermarket Data): Spray cone angle 136°; 6 holes; hole diameter ~0.135 mm; thread M14 × 1.5; max pressure 180–220 MPa. These are aftermarket reference values — request supplier confirmation for your production batch.
- VerifiedSupplier Warranty Available: One supplier (CNDIP) lists a 6-month warranty.
- PendingBench Flow & Spray Pattern Data: No public flow rate (cc/min at specified pressure) or spray pattern validation data for this OEM number. Request from supplier: bench test report (flow rate, spray pattern, leakage).
- PendingInstallation Success Rate: No repair order statistics available.

- Clean the injector body and nozzle retaining nut thoroughly before disassembly.
- Remove the old nozzle; inspect the needle and seat for wear.
- Install the new nozzle with a new copper washer (if applicable).
- Torque the nozzle retaining nut to TBC — refer to Denso/Zexel service specifications for 105017-3260.
- Test on a diesel injector bench for opening pressure, spray pattern, and leakage before installation.
- Install the injector into the engine; torque to OEM specification. Bleed the fuel system.
Use clean, water-free diesel fuel. Replace fuel filters at OEM intervals. Inspect injectors if rough idle, smoke, or power loss develops.
