- Generator Set:
- C175-16 (S/N: WYB1-UP)
Description of Change: The orifice tip of the new injector was redesigned. The new design makes the tip more resistant to cavitation erosion than the tip of the previous injector.
Adaptable To: The new injector is adaptable to C175-16 Generator Set Engines back to first production. However, do not use the new injector with any previously used injectors.
If any other injectors are used with the new injectors, a 268-2 Programmed Parameter Fault : Erratic, Intermittent, or Incorrect diagnostic code will be activated when installing the injector trim files.
The new parts and the previous production parts are listed in Table 1.
The new injectors are effective with WYB00620.
Note: The previous production parts remain available for service. If your engine continues to use the previous production software, also use the previous production injector.
