TO ALL DISTRIBUTORS AND DEALERS

Gentlemen,

     When cases of oil leaks are reported from rear axle hubs, the
following procedure should be followed:-

 1.  Ensure that the seal bearing surface on the axle housing is 
     smooth and free of tool chatter marks.

 2.  Check the hub for running true on the axle.  Eccentric hubs
     should be replaced.

 3.  Make sure that the axle breather is in operating condition so
     that no pressure build up at any speed may occur.

 4.  Ensure that only S.A.E.80 or 90 lubricant isused.  Do not over-
     fill the axle but rather fill to about 1/4" below the level of the 
     filler plug.

 5.  Ensure that the spring tension of the oil seal is sufficient.

     In cases where the above procedure has not proved satisfactorry, 
     and where continuous complaints have been received:-

 6.  Install an oil seal baffle between the hub bearing and the oil 
     seal.  The part numbers for each baffle applicable to the 
     three series of axles are given below:-

                  "A" Series   ...  Part No. 2A.7293
                  "B" Series   ...  Part No. 1H.7077
                  "C" Series   ...  Part No. 1B.7525

                                    Yours very truly,

                                     Oeter Millard,
