What should be done to a new shaft sleeve before it is put on a shaft if it uses an o-ring?

Explanation:
Heating the sleeve before installation helps it expand slightly so it slides over the shaft smoothly and doesn’t damage the o-ring. Because o-rings are heat-sensitive, direct heat from a torch can scorch or deform the elastomer and harm the seal. A safer, controlled method is to warm the sleeve in a bath of water or in oil. This provides even heating and makes the sleeve easier to fit without risking damage to the o-ring. So, warming the sleeve with water or oil is the appropriate approach.
