The Bosch 0432231860 is a new, genuine Bosch mechanical fuel injector, a complete nozzle and holder assembly, for the John Deere 6466T, the turbocharged 7.6 L (466 cu in) six-cylinder engine. John Deere’s number for it is AR70187. The engine takes six.

The 6466 used more than one Bosch injector, and they are not the same part, so match the number on the one that came out. This is the older 7.6 L engine, not the later 6076 or 6081, which take the 0432131 series injectors. Injectors are replaced for hard starting, smoke, a miss, fuel knock or low power. Replace all six so opening pressures match across cylinders.

Specifications

Fits / Applications

• John Deere 6466T 7.6 L turbocharged engines built with nozzle AR70187
• Six injectors per engine. Match the number on your old injector.

These are mechanical nozzle and holder assemblies, so the calibration is in the injector: fit the same Bosch number that came out, and replace all six so opening pressures match. Use new sealing washers, clean the bores and seats, and torque to the John Deere spec for your engine.
