Hello Guest! Welcome to our store!
Adjusting Bolt 5.23.139 / 150.23.161 is used in several assemblies of HTZ tractors and is designed for the adjustment, fastening, and clamping of various mechanisms. Featuring an M10 thread and an overall length of 25 mm, it fully matches the original factory specifications, ensuring a direct replacement without modification during installation.
Its primary application is in the parking brake system. The bolt is installed in Brace Bracket 151.46.014A, where it is used to adjust the tension of Parking Brake Band 151.46.001-1. By adjusting the bolt, the contact pressure of the brake band against Brake Drum 125.46.101-1 can be precisely set, ensuring efficient parking brake operation and secure tractor immobilization. Proper adjustment helps prevent brake slippage and reduces premature wear of the brake band.
In addition to the brake system, Adjusting Bolt 5.23.139 / 150.23.161 is used in the diesel engine preheater system, where it clamps the bracket around Preheater Boiler 150.23.013, ensuring secure mounting of the assembly. The bolt is also used in the engine control system as part of various adjustment and fastening mechanisms.
During routine maintenance, the bolt should be inspected for thread damage, deformation, and general wear. If the threads are damaged or the bolt shows signs of excessive wear, it should be replaced to maintain accurate adjustment and reliable operation of the corresponding mechanism.
Adjusting Bolt 5.23.139 / 150.23.161 is compatible with HTZ wheel and crawler tractors, including T-150K, T-150, T-151K, T-156, HTZ-17021, HTZ-17221, HTZ-181, HTZ-242K, HTZ-248K, and other HTZ models equipped with the same parking brake, diesel preheater, and engine control system design.
