F00041N029 Diesel Common Rail Injector Repair Kit — Legacy Engine Seal Restoration & Supply Chain Continuity Set

 

When a Tier 2/Stage II diesel engine still powers a remote irrigation pump or a mine‑site generator, the parts network has often moved on. A single failing injector can idle the entire asset for weeks while a replacement unit is sourced - if one can be found at all. For the Bosch 0414700002 injector, that search is becoming harder every season. The F00041N029 Injector Repair Kit offers an alternative path: a complete seal and shim restoration that returns the original injector to factory hydraulic specification, keeping aging but mechanically sound common‑rail engines productive without hunting for an obsolete part number.

 

The solenoid and nozzle needle inside a Bosch CR injector routinely outlast the elastomer seals by a factor of three. On a **0414700002** unit with 12,000–15,000 hours of service, the solenoid still clicks, the spray pattern is intact, but the return‑flow volume has climbed past 200 ml/min - ten times the service limit. That leak is purely hydraulic: the body O‑rings have lost their radial compression, and the copper thrust ring has work‑hardened. Replacing the entire injector addresses the leak, but it also discards a perfectly good solenoid and nozzle assembly. The **F00041N029 repair kit** targets only the worn components, restoring the injector's sealing integrity without touching the calibrated electromagnetic circuit or the injector‑specific IMA code.

 

Every element inside the F00041N029 box is dimensionally verified against the 0414700002 body:

▸ FKM body O‑ring set – Ø7.6×1.8 mm, Ø14.0×2.0 mm, Ø18.5×1.5 mm. Formulated for continuous service from −35 °C to +200 °C, with a compression set below 13 % after 2,000 hours at 190 °C.
▸ Copper crush thrust ring – annealed to 45–55 HV, Ra 0.7 µm. Progressive‑collapse geometry seals the nozzle seat at 1,800 bar without extruding.
▸ Nozzle‑retaining‑nut gasket and bi‑metallic combustion seal washer – dual barrier against combustion gas ingress and nozzle‑protrusion drift.
▸ Return‑line connector O‑ring – 9.8 × 1.5 mm FKM, eliminating the external fuel weep often misread as a high‑pressure pipe leak.
▸ Laser‑marked adjustment shim set – 0.90 mm to 1.30 mm in 0.02 mm steps, allowing nozzle‑opening‑pressure (NOP) calibration to ±5 bar of the injector's nameplate.

 

The **F00041N029 Injector Repair Kit** is engineered exclusively for:

0414700002

This injector is found on early‑generation common‑rail platforms including Deutz 1013/2012, Volvo Penta MD series, and various industrial power units that entered service before the Euro III/Stage IIIA transition. The laser‑etched part number on the solenoid cap is the definitive identifier. If it reads 0414700002, the kit fits without modification.

 

Q1: My engine is over 20 years old - will the F00041N029 kit still be available?
The kit is produced using standardised FKM and copper components that are not tied to the engine's production lifecycle. As long as 0414700002 injector bodies remain in service, the kit is expected to be available from independent aftermarket suppliers.

Q2: On which engines is the 0414700002 injector most commonly found?
Primarily Deutz 1013/2012 series, certain Volvo Penta marine and industrial engines, and some early Iveco and FPT platforms. Always verify the laser‑etched number on the solenoid cap.

Q3: I don't have a CR test bench. Can I still verify the repair?
Yes. Perform an on‑engine graduated‑cylinder leak‑off test at warm idle. Any value below 15 ml/min is acceptable. Also monitor cold‑start cranking time and oil level trend over the next 50 hours - both should normalise after a successful reseal.

Q4: The injector has been running high‑sulfur diesel (500+ ppm) for years. Will the FKM seals hold?
FKM is chemically resistant to acidic combustion by‑products associated with high‑sulfur fuel. However, check the nozzle tip for sulfur‑induced corrosion. The repair kit addresses sealing only; a heavily corroded nozzle requires replacement.

Q5: After installing the repair kit, do I need to update the ECU or enter a new injector code?
No. The original injector body, solenoid, and IMA code remain unchanged. The ECU will self‑adapt fuel trims during the first warm‑up cycle. No dealer software or coding is needed.

Q6: Can this kit help if my engine has been in long‑term storage and now has starting problems?
Often yes. Seals can dry out and take a set during prolonged inactivity. Resealing with the F00041N029 kit restores the hydraulic pressure‑holding capability needed for a quick start, even after the engine has been idle for months.
