Bosch 0445120075 Common Rail Injector (0 445 120 075) | OEM 2855135 / 504128307 For Case IH & New Holland 6.7L Applications

On farms and job sites, an injector isn't judged by "performance"-it's judged by hours without drama. If you're searching 0445120075, you're likely dealing with a CNH/industrial diesel that must start clean, pull hard, and keep fuel consumption predictable across long duty cycles. The Bosch 0445120075 common rail injector (Bosch No. 0 445 120 075) is widely cross-listed in catalogs for CASE IH / Ford New Holland applications and is commonly referenced by OEM and Bosch exchange numbers used by fleet and workshop purchasing teams.

✅ Bosch number: 0445120075 / 0 445 120 075 
✅ Fuel system type: Common Rail (CR)  
✅ Bosch exchange / reman reference often shown: 0 986 435 530 / 0986435530  
✅ Typical OEM cross references: 2855135 / 504128307 / 500060542 (commonly listed together)  

Think of those OEM numbers as the "purchase language" of workshops: many buyers won't search Bosch first-they'll search 2855135 or 504128307, then confirm it maps back to 0445120075.

 

Independent distributors and specialist diesel retailers frequently present this injector for CASE IH / New Holland equipment using 6.7L engines (often shown in listings as relevant to certain CNH machines/variants). 

You may also encounter marketplace listings that mention specific equipment models (e.g., certain New Holland / Case machines) tied to a 6.7L application; treat those as supporting hints and still verify by Bosch number + OEM cross reference. 

⚠️ Fitment note: agricultural/construction equipment can have multiple calibrations across model years and emissions tiers. The safest route is matching 0445120075 / 0 445 120 075 and confirming the OEM cross reference used on your parts breakdown.

 

 

In field work, the injector's real job is repeatability:

🔸 Stable pilot/main injection control → smoother combustion and less knock under load
🔸 Consistent metering → predictable fuel burn over long days
🔸 Healthy sealing & return flow → faster pressure build for cold starts and fewer "hard-start mornings"

When injectors drift, the symptoms typically show up as:

❗ Hard start (especially cold) or extended cranking

❗ Rough idle and uneven pull under load

❗ Smoke under acceleration / heavy work

❗ Fuel consumption creep (ECU/engine compensations and imbalance)

Replacing with the correct 0445120075 is a "reset" of fuel delivery accuracy-helping the engine return to clean, even combustion and stable operation under load.

 

 

Because buyers often compare listings side-by-side, here are catalog-type details commonly shown online:

Fuel mixture formation: Common Rail (CR)  

Seal ring info: some listings specify "with seal ring" (important for installation prep and avoiding compression leaks)  

Exchange/reman mapping: 0445120075 ↔ 0 986 435 530 / 0986435530 is frequently shown in listings  

Also, reputable sellers sometimes highlight that a unit is new, boxed, sealed, and note warranty/returns-useful cues for buyers who need a clean procurement trail

 

You'll generally see two purchasing paths:

🆕 New genuine Bosch

Often described as "brand new boxed" or "original sealed packaging"  

Typically avoids "core return" complications

♻️ Bosch exchange/reman (by exchange number)

Frequently referenced as 0986435530 / 0 986 435 530  

May involve core return/surcharge policies (varies by supplier)

For fleet managers, the best practice is to standardize the purchasing spec: Bosch number + OEM cross-ref + new/exchange status.
