ROLLER - SIDE UPRIGHT (Doosan DWYT9074583-00)

A worn side upright roller can cause uneven wear on mast channels and increase operating resistance. This aftermarket replacement part references the Doosan catalog number DWYT9074583-00. The roller is a load-bearing component that guides vertical movement along the upright assembly. Its plain mechanical function is to reduce friction between moving mast sections. A common failure consequence is that a seized or flat-spotted roller can produce metal-to-metal contact, leading to galling on the upright surface. Keeping the roller in sound condition helps maintain smooth vertical travel and reduces strain on the mast structure. Verify the serial number or application, then call (562) 693-7748.
