CIRCLIP 53-82342M REC93450-13022

Function and technical context

The 53-82342M circlip is an elastic retaining ring that secures the axial position of critical components in Mercury, Mariner and MerCruiser marine engine drive systems. This element works to drive shafts and gears, maintaining precise alignment under the continuous vibrations and loads typical of naval operation. Its deterioration or loss compromises the structural stability of the transmission, and can cause progressive misalignments, accelerated gear wear and, in extreme cases, catastrophic failure of the propulsion system.

When to replace this part?

Circlip retaining rings require visual inspection at each seasonal maintenance interval, especially after operations in debris water or after impacts against submerged objects. If you detect abnormal play between the shaft and its support, or if you see the circlip bent, fractured or with loss of elasticity, it must be replaced immediately. Preventive replacement during transmission dismantling works avoids future repair costs and guarantees the integrity of the propulsion system on prolonged voyages.
