Hello Guest! Welcome to our store!
The lever shaft 151.56.018-2A is an important component of the old-style hitch for one hydraulic cylinder. Performs the function of transmitting force from the hydraulic cylinder through the levers to the lower links, ensuring stable lifting and lowering of attachments.
The shaft is an assembly part consisting of:
lever shaft 151.56.117-1,
two bushings 77.60.170-3, which are installed inside the shaft housing and ensure precise centering and easy free movement of the upper axis.
The bushings play the role of wear-resistant guides, thereby increasing the service life of the entire assembly and reducing the risk of jamming.
Shaft 151.56.018-2A is part of the assembly of the upper axle 151.56.016-3A, through which the main loads from the hydraulic cylinder are transmitted.
It is fixed in the rod lever 150.56.015-1, and lifting levers are installed on its splined parts:
150.56.151A - left,
150.56.152A - right.
These arms connect to the linkage links to form a complete lifting mechanism.
The shaft is made of high-strength steel, resistant to dynamic and shock loads.
The design is suitable for restoring old-style hitch units, which is especially important for equipment that has been in use for many years.
The presence of replaceable bushings simplifies repairs - when wear occurs, only the bushings are replaced, and the shaft itself often remains operational.
Used in the attachment of HTZ tractors:
T-150, T-151, T-156, T-150K of the early years, HTZ-17221 of the first releases and other models with the old linkage system for one hydraulic cylinder.
