Half Coupling Washer 236-1029276-Б is used in the fuel injection pump (FIP) drive of YaMZ-236 and YaMZ-238 engines. It is installed in the fuel injection pump drive coupling assembly, where it ensures proper operation of the half coupling, reduces wear on mating components, and improves the reliability of the drive mechanism.
The washer is manufactured from textolite (phenolic laminate), a durable composite material known for its excellent wear resistance, resistance to engine oil, and stability under varying temperatures. These properties allow the washer to withstand continuous operating loads, minimize friction between moving parts, and extend the service life of the fuel injection pump drive.
When servicing the fuel injection pump drive, it is recommended to inspect the half coupling, mounting hardware, and washer for wear. If excessive wear, cracks, or deformation are found, the washer should be replaced to prevent drive malfunction and maintain accurate fuel injection timing.
Half Coupling Washer 236-1029276-Б is used on HTZ tractors and other agricultural, construction, and industrial equipment powered by YaMZ-236 and YaMZ-238 diesel engines.
