Lock washer 150.37.149 is a fixing element designed to securely hold the nut 150.37.420-1 at the end of the secondary shaft 151.37.037-2 of the gearbox. The design of the washer includes two metal folding legs (legs), which, after tightening the nut, bend on its edge, preventing spontaneous unwinding under vibrations and loads during tractor operation.
Made of durable hardened steel, resistant to deformation and oil. It is a consumable item and must be replaced every time the gearbox is disassembled or the unit is maintained. Using a worn or bent washer may cause loosening and damage to the shaft threads.
Application: gearbox of tractors HTZ, T-150, T-151, T-156, HTZ-17221, HTZ-242, HTZ-248 and other models with similar types of transmissions.
