This section contains troubleshooting to locate and correct the cause(s)

of more than one half of the main oil pump magnetic plug being covered

with metal chips when no other rotation or metal chips were noted. The

reduction gearbox (RGB) oil return line feeds directly into the oil pump

passage that houses the magnetic plug. The only possible source of metal

chips on the oil pump magnetic plug is the RGB. The art on this page

provides an overview of the systems described above. Refer to this page

along with in-text art while performing troubleshooting.
