Protective cap 150.00.033-1A is an element of the fastening structure that ensures reliable fixation and protection of the gearbox support attachment point. It repeats the shape of the bracket 150.00.074, which together with the rubber cushion 150.00.073 is located directly below it. These elements work in tandem to provide shock absorption and damping of vibrations transmitted from the gearbox to the tractor body.
The design of the cap 150.00.033-1A provides two mounting holes that exactly match the holes in the bracket and the cushion. Bolts 150.00.257 pass through them, with which the entire assembly is pulled together and pressed against the gearbox support 150.00.104-1, creating a rigid but shock-absorbing connection. This arrangement helps to increase the service life of parts and reduce noise and vibration levels.
The unit is used in SMD-60 diesel units that are part of the transmission of HTZ tractors, including models T-150, T-151, T-156 and other machines with a similar power transmission configuration.
