20Y-27-41150 (20Y2741150) part number component is a critical shaft and gear carrier structure that ensures high torque transmission in the travel and powertrain systems of crawler excavators. Located in the movement transmission mechanism of the PC200-8 series machines, this part balances rotational force under heavy field conditions and supports the harmonious operation of wheel or reduction gears.
Final Drive Replacement and Assembly Notes
During replacements in powertrains, inner and outer gear profiles as well as shaft bearing surfaces must be thoroughly inspected. Adjusting gear backlash according to manufacturer tolerance values during the assembly stage is one of the factors directly affecting system lifespan. Before installing the new carrier, old oil residues inside the housing must be completely cleaned and filled with gear oil of appropriate viscosity.
Compatibility Check
Before ordering parts, it is important to compare your machine's serial number and the original codes on the existing reduction gear. You can check the part number to verify that this 20Y-27-41150 coded carrier part is fully compatible with your machine's reduction gear group.
