The right method to put an oil seal in a housing

  1. Jul 24, 2014 #1
    i have a question, when i put a oil seal in a housing, should i put grease between the housing and the oil seal? because that is more easy to out in.

    Can explain the theory to me please?

    If you use grease the surface of the oil seal it will be able to slide out again during or after assembly.

    Many sealants such as those used on gaskets and screw threads are lubricants during assembly, then they set to become both a seal and a retaining "glue".

    It's a double edged sword. Under pressure, the seal material is more likely to migrate. Ease of seal replacement is a noble idea, but, easy access to seal surfaces is not necessarily a design priority.
