SEAL KIT - HYDRAULIC MOTOR (JLG JL139542SJ)

A damaged seal kit can allow hydraulic fluid to bypass the motor, reducing system pressure and causing sluggish or erratic operation. This aftermarket replacement part references the JLG catalog number JL139542SJ. The seal kit contains multiple sealing elements designed to contain fluid within a hydraulic motor. A plain mechanical function of these seals is to prevent external leakage at rotating shaft interfaces. A concrete generic failure consequence is that worn seals can lead to internal cross-port leakage, which reduces torque output and generates excessive heat. The item ships at approximately 0.298 pounds. Verify the serial number or application, then call (562) 693-7748.
