Created Modified Rev. Changed by Change

When inspecting OD lip seals where the ID of the seal must make full contact when placed on a specified (Per Manufacturing Print) mandrel. THE SEAL MUST SNAP OVER THE MANDREL SO IT WILL NOT ROTATE. If there is any questions please ask a member of management.

 

NOTE: These seals were placed in a groove in the piston and the piston is put into a cylinder. We have some parts at Caterpillar that were being cut when the piston was inserted into the cylinder. If the seal ring is not snug in the bottom of the groove it can hang out in a spot and be sheared off between the piston and cylinder upon insertion.
