Elastomeric camshaft seals are used in two versions, the elastomeric seal in the first version has a spring and a V-shaped working edge (fig. 2.192).
Fig. 2.193. Elastomeric seal (second option): 1 – flat working edge; 2 – safety sleeve
In the second version, the elastomer seal has a flat working edge and a safety sleeve, which also serves to install the seal on the engine (fig. 2.193).
