Bolt 151.72.321 is a fastener used in the wheel gear assembly (the so-called final drive) of HTZ tractors. The bolt has thread characteristics M20×1.5-6g×60 and is used in the amount of 8 pieces per side. Designed for reliable fastening of hub 151.39.105-6 to the gearbox housing.
When installed assembled with the rear beam locating pin A02-26, the hub receives the designation hub shaft 151.39.013-7, which is important to consider when selecting spare parts. Reliable fixation of this area is especially critical, since large torsional and axial loads are transferred to the bolts when the tractor moves, especially on uneven or heavy soil.
The part is used in the design of the rear and front axles of HTZ tractors, including models T-150, T-150K, HTZ-17221, HTZ-242K, HTZ-248K and other machines with a similar drive axle design.
