BEARING - MAST ROLLER (Doosan DWYT5051112-79)

DWYT5051112-79: A worn mast roller bearing can cause uneven roller wear and eventual binding in the mast channel. This aftermarket replacement part references the Doosan catalog number DWYT5051112-79. The bearing supports the roller that guides the mast assembly during vertical movement. A seized or failing bearing may produce metal debris that contaminates the mast channel surfaces. Keeping the bearing in sound condition helps maintain smooth roller travel and reduces side-load stress on the mast structure. Verify the serial number or application, then call (562) 693-7748.
