The Bosch 0432131736 is a new, genuine Bosch mechanical fuel injector, a complete nozzle and holder assembly, for John Deere 6081A and 6081H 8.1 L PowerTech engines and the 6076H 7.6 L. John Deere sells it as RE64391. It is found in the 850C crawler dozer, the 770C, 770CH and 772CH motor graders and the 8100 tractor. The engine takes six.

The 6081 was built with several Bosch injectors, each calibrated for a group of engine models, and they are not interchangeable. This one is the RE64391 injector. Its sister numbers are the 0432131766 (RE57152) and the 0432131765 (RE61593). Injectors are replaced for hard starting, smoke, a miss, fuel knock or low power. Replace all six so opening pressures match across cylinders.
