Lever shaft bushing 77.60.170-2 is a guide bushing installed inside the lever shaft of the hitch on HTZ tractors. Its main function is to ensure accurate positioning and reliable fixation of the upper axis 150.56.161, which runs inside the spline shaft, and also to reduce wear of the mating surfaces during operation of the hinged mechanism.
The bushing is mounted inside the following types of shafts:
151.56.018-2AR - version for one hydraulic cylinder (old style hitch);
151K.56.018 - version for two hydraulic cylinders (new sample attachment).
Manufactured from high-strength bronze or hardened steel with an anti-friction coating for durability, minimal wear and smooth operation.
Application:
Bushing 77.60.170-2 is used as part of the linkage of tractors T-150, T-151, T-156, HTZ-17221, HTZ-242, HTZ-248 and other models.
Features:
ensures correct coaxial rotation of the axis and shaft;
reduces backlash and vibration in the mechanism;
Easily replaced during maintenance without dismantling the entire unit.
The part is one of the key elements for the durability of the attachment, especially when working with heavy attachments.
