This listing is for 1 (ONE) fully rebuilt injector for the John Deere 6404 engine. We are a full fuel injection shop that rebuilds these every day, not an amateur slapping a nozzle in a body and calling it rebuilt. We only use brand new Bosch nozzles, not re grinds, re chromed (commonly found in John Deere factory reman) or chinese parts. Our process includes lapping and polishing of all internal sealing surfaces and resetting of the pressures to within 50psi of eachother on a test stand.

These are used in the following applications:

All of our in house rebuilt injectors are a PRESSURE BALANCED set. This means that I pop test  them so their pressures are within 50 psi of each other. Doing it this way usually results in them being exact pressure matched but 50 psi is a standard balance and the widest that I will allow.


Our injectors are rebuilt by the owner of the business with 20 years and 10's of thousands of these things of experience, not "the new guy" as most shops have them do. 

Our process is: Disassemble, wash, and sand blast and wire wheel the relevant parts of the bodies. Once the parts are blasted we put them in a blackening solution. Then all metal to metal sealing surfaces are lapped on a lapping machine and polished to guarantee a perfect metal seal. (A lot of shops don't do this to save time, but we aren't into taking short cuts) Then we assemble and reset the opening pressures to 4000-4100 psi within 50psi but typically are within 25psi or less to give a nice smooth running engine.

Since we are a full fuel injection shop we can stand behind what we sell and know what it is we are selling you, not like some of these other sellers that are just buying surplus parts and selling them then when there is a problem they tell you it's not their problem and don't even know how to help you.

If you have any questions you can call Badger Diesel Monday - Friday 8am to 6pm
