The 43271000190 is an application-specific clutch master cylinder built for XCMG QY25K and QY50K series truck cranes. As a core component of the chassis hydraulic clutch control system, it translates mechanical input from the control linkage into stable hydraulic pressure to manage clutch engagement and disengagement during both crane travel and on-site operation.

This unit features a one-piece cast iron body for high structural strength and durability under frequent heavy-duty use. It is supplied complete with an adjustable push rod and clevis assembly, enabling accurate installation and free-play adjustment to match original equipment specifications.
