Offering high durability in heavy equipment powertrain systems, this part is one of the critical gear components that regulate torque transmission and gear ratios within the transmission system. Designed to work harmoniously in the transmission systems of heavy machinery operating under harsh field conditions, the hardware with stock number 419-15-12261 (alternatively written as 4191512261) ensures an exact fit with machines having the specified serial numbers.
When replacing gears in the powertrain, carefully inspecting the condition of shaft bearings, washers, and snap rings directly extends the service life of the gears inside the transfer case. During assembly, lubricating the gear surfaces with transmission oil of appropriate viscosity is a fundamental maintenance step that minimizes initial friction wear.
To ensure the transmission system continues to operate smoothly in field operations, it is of great importance to adjust transmission backlash according to manufacturer tolerance levels and not neglect periodic oil change intervals.
This transmission gear is used in WA200-1, WA250-1, WA300-1, and WA320-1 heavy equipment models.
