This aluminum center pulley frange is intended for placement inside the center pulley of the YZ-4 chassis. It is supplied as 1 pcs and functions as a replacement inner flange for YZ-4 center pulley assemblies.
The frange locates the inner face of the center pulley and helps maintain axial alignment of the center drive. Replacing the inner frange during service restores the correct spacing and provides a uniform contact face where the pulley sits.
Fitting the frange requires disassembling the center pulley assembly to remove the original inner flange, fitting this aluminum frange, and then reassembling the pulley. After refit, check center drive alignment and axial clearance before use.
