Description Of Change: Sealant is now used for alternator and auxiliary drive pulleys. The Loctite® 648 (retaining compound) or Loctite® 120541 (core plug sealant) prevents oil leaks between the pulley and the wear sleeve. Prior to installing the sleeve to the pulley, apply the sealant to the inner side of the sleeve. Ensure that no excess sealant is allowed on the running surface of the sleeve.
