Continental Manufacturing Roller Lockwasher

Continental Manufacturing Roller Lockwasher

This drum roller lockwasher is a critical component of the rear pedestal roller assembly on Challenge Cook Brothers (CCB), Continental, and compatible rear discharge concrete mixers. It works in conjunction with the shaft locknut (OEM 1030670) to maintain proper bearing preload and prevent the nut from backing off during transit and mixing operations. Replacing a worn or damaged lockwasher during routine roller maintenance or bearing replacement ensures the structural integrity of the drum roller shaft and prevents catastrophic roller failure.
