An oil relief plug regulates and seals the oil cavity within a roller's drum drive system, preventing overpressure buildup and stopping oil from escaping the housing. It plays a quiet but critical role in keeping the drive components lubricated and protected during compaction work. When this plug is damaged, missing, or incorrectly seated, oil can leak from the drum assembly, leading to overheating, accelerated wear on drive internals, and potential failure of the drum drive system.
