Thoroughly clean the sleeve at the back of the pulley, and look for any roughness on it where it touches the seal. If necessary, smooth it with fine wet-and-dry abrasive paper.
Friction modifiers: Friction modifiers help reduce friction when your engine is operating under high temperatures and with heavy loads. This additive can also help you maximize your fuel efficiency.
One of the key advantages of the 40mm rubber gasket is its flexibility and resilience, allowing it to conform to irregular surfaces and maintain a tight seal under varying conditions
. This property makes it an ideal choice for sealing joints, flanges, and connections in industrial equipment and machinery.40mm rubber gasket

For the housing stop installation technique, set the seal depth flush with the bore’s interior shoulder. This technique ensures that the seal is perfectly aligned with internal housing components. A depth gauge can be crucial here to confirm that the seal is positioned correctly.
(3) The oil seal with general pressure has poor pressure bearing capacity, and the oil seal will deform when the pressure is too large. In the case of excessive pressure, a pressure-resistant bearing ring or a reinforced pressure-resistant oil seal should be used.
