This OE C000395 linear clutch actuator adopts high-precision electronic linear displacement sensing technology, which can real-time feedback clutch push rod travel data to AMT ECU, accurately control clutch separation and engagement speed, effectively avoid gear shifting jitter, power stalling and gear impact. The thick integral die-cast aluminum base with uniform reinforcing ribs bears long-term reciprocating hydraulic pressure without deformation or crack. A full-circle elastic rubber sealing ring is embedded between the housing and mounting flange to completely isolate hydraulic oil and external dust, solving common oil leakage faults of split inferior actuators. The wear-resistant metal ball head push rod is matched with dust-proof corrugated boot to reduce friction loss and extend service cycle. Symmetrical multi-group mounting bolt holes are CNC machined on the flange, fully copying Dongfeng Cummins engine chassis transmission installation size, supporting direct plug-and-play whole-unit replacement without cutting or modifying transmission brackets.
