SEPARATOR 6L2-45987-01

Function and technical context

The 6L2-45987-01 separator is a critical component of the lubrication system in Yamaha four-stroke engines. This piece acts as a flow divider in the distribution of oil to the different sections of the engine, ensuring that each area receives the amount of lubricant necessary for optimal operation. Its correct performance is essential to maintain oil pressure at design values ​​and ensure the protection of bearings, pistons and friction surfaces. A defective or deteriorated separator can cause poor lubricant distribution, generating insufficiently lubricated friction zones and, consequently, accelerating premature wear of internal components.

When to replace this part?

The separator must be checked during periodic maintenance services, especially if an abnormal drop in oil pressure is detected on the pressure gauge or if the engine emits louder noises at idle and half load operation. Although this component has a long useful life under normal operating conditions, it is advisable to inspect its condition and consider its preventive replacement every two seasons of intensive navigation or after carrying out extensive work on the lubrication system. Preventive replacement avoids complex diagnoses in the future and ensures safe navigation continuity.
