PROBLEM
The existing 162-9612 Fuel Transfer Pump Group that is part of the 162-9608 Unit Injector Hydraulic Pump Group can fail on certain 3126B Gen Set Engines. The failure has been associated to undersized splines inside of the fuel transfer pump. This may cause an accelerated wear to the splines of the fuel transfer pump and the unit injector hydraulic pump.
