The drive shaft with code K 32321 is a key transmission component that transfers torque to the vertical worm gear in the Sulzer ZV40/48 engine. This shaft must withstand high torsional loads and deliver consistent power with minimal backlash. Crafted from robust materials and manufactured with high precision, it ensures reliable operation of the worm gear mechanism, which may be part of engine barring or auxiliary drive systems. Its performance directly impacts the efficiency and durability of critical drivetrain assemblies.
