Group 1: The following serial numbers will need two couplings between engine and gearbox: LGS00195 through LGS00198, and GFR00195
For all other serial numbers in Group 1, only one coupling is needed.
Perform periodic coupling inspections as recommended in Operations Manuals, and inspect per guidelines in REHS3401. If guidelines are exceeded, replace coupling with new coupling part number, that is constructed of lower hardness, as listed in the Parts Needed. |
