This is the Alliant Power AP52905, a Denso common-rail fuel injector remanufactured by Alliant Power for John Deere 4045 4.5L and 6068 6.8L PowerTech engines. It is the Denso 095000-7150 injector and it replaces John Deere RE534111, RE533505, DZ100220 and SE501933. Catalogs list it for the 624K, 624KR and 644K loaders with Tier 3 engines.

Hard starting, a rough idle, a miss on one cylinder, white or black smoke, fuel in the oil and low rail pressure faults are the usual reasons these injectors get replaced. Dirty or wet fuel is the common cause, so sort out the filters and the tank before new injectors go in. John Deere used several different Denso injectors on the 4.5L and 6.8L common-rail engines, and the same machine model can take more than one of them depending on the engine build. In this family, AP52900 is the 095000-5050 injector, AP52901 is 095000-6490, AP52903 is 095000-6320, AP52905 is 095000-7150 and AP52906 is 095000-6500. The 624K and 644K show up under both AP52901 and AP52905, so the number on the old injector decides.

Specifications

Fits / Applications

• John Deere 624K and 624KR loaders
• John Deere 644K loader
• Catalogs list it for Tier 3 engines
• Only engines built with the Denso 095000-7150 injector. Check the number on your old injector.
• Four injectors on the 4045, six on the 6068

Each injector carries its own trim code. That code has to be programmed into the engine controller for the cylinder it goes in, or the engine will not run right. Fit new fuel filters, keep every line and fitting clean and capped while the system is open, and torque the hold-down and the solenoid terminal nuts to the John Deere figures.

Frequently Asked Questions

Will the AP52905 fit my John Deere 624K loader?

Catalogs list the 624K under both AP52905 and AP52901, so the machine model alone does not settle it. Match the Denso 095000-7150 or RE534111 number on your old injector, or call 530-668-0818 with the engine serial number.

What numbers does the AP52905 replace?

Denso 095000-7150 and John Deere RE534111, RE533505, DZ100220 and SE501933.

Is it new or remanufactured, and is there a core?

It is a Denso injector remanufactured by Alliant Power. A refundable core applies, and it comes back when we receive your old injector.

Does this injector need to be programmed?

Yes. Each injector has its own trim code, and that code is entered into the engine controller for the cylinder the injector goes in.
