Attention! The rear oil seal can only be replaced as a complete assembly with the holder.
Attention! The seal must be made of PTFE material, the distinguishing feature of such a seal is a multi-profile working edge (see figureCrankshaft oil seal) and the absence of a spring. Before installation, do not lubricate the working lip of the seal and the shaft; they must be dry and clean.
