Lycoming LW-14260 Tachometer Drive Seal is a replacement oil seal designed for the tachometer drive assembly on compatible Lycoming aircraft engines. It provides a reliable seal around the tachometer drive shaft, helping prevent engine oil leakage while maintaining the integrity of the accessory housing.

The tachometer drive transmits rotational motion from the engine accessory gear train to the aircraft's tachometer system. A properly functioning seal is essential to retain engine oil within the accessory case while protecting the drive assembly from contaminants that could affect performance or service life.

Manufactured to Lycoming specifications, the LW-14260 seal is engineered to withstand continuous exposure to engine oil, elevated operating temperatures, vibration, and pressure variations encountered during normal aircraft engine operation. Its precision dimensions ensure proper fit and dependable sealing performance throughout scheduled maintenance intervals.

Replacement of the tachometer drive seal is recommended whenever the tachometer drive assembly is removed or serviced, or whenever evidence of oil seepage is observed. Installing a new seal helps restore leak-free operation and contributes to the overall reliability of the engine lubrication system.
