Timing Mark Identification On Fuel Pump Gear{1286,1251,1272}

Usage:




RT50, RT50 SA, RTC60 And RT60 Telescopic Material Handlers Equipped With Perkins 4.236 Diesel Engine

The timing mark on the fuel injection pump gear currently has the figure "23" or "24" stamped next to it. See the illustration. The numbers are actually the last two figures of the suppliers' part number for the fuel pump gear and NOT the static timing mark degree figures. However, since these figures have been identified in error as degree figures, they will be moved to a new location on the gear in the future.


371608 Gear. Location of timing mark with the figure "23" or "24" stamped nearby.
