Roller Drum Rebuild

Roller drum rebuild service covers diagnosis and repair of compactor and roller drums on single-drum and double-drum compactors, including CAT, Bomag, Volvo, Hamm, and Sakai models. Typical failure points are vibratory shaft/bearing wear, eccentric weight breakage, and excessive shell thinning due to abrasive soil or aggregate. Symptoms often include diminished vibration amplitude, uneven compaction, oil leaks along drum ends, or audible thumping from bearing degradation. / Adam inspects bearing condition, checks vibratory shaft endplay with a dial indicator, and tests vibration circuit pressure and hydraulic flow at manufacturer ports. Shell thickness is measured with calipers; excessive thinning under 10mm typically demands drum section replacement or installation of wear sleeves. / Field repair involves removal and reinstallation of drum end caps, replacement of sealed roller bearings (often 231xx or 223xx series spherical roller types), fabrication of custom seals, and alignment of the stored eccentric system. Adam handles mobile welding repair for cracked drum shells or bracket fractures, using 7018 stick or MIG, managing preheat for shells over 1/2 inch thick. Service eliminates the need for costly shop teardown and minimizes compactor downtime.
