4. Install the pressure seals, flat side outward, into the
grooves in the thrust plates. Follow by carefully placing
theback--up seals, flatside outward,between thepres-
sure seals and the grooves in the thrust plate.
5. Applyalightcoatingofpetroleumjellytotheexposed
side of the front cover.
6. Lubricatethedrivegearshaftwithcleanhydraulicoil.
Insert the drive end of the drive shaft through the thrust
platewiththepressuresealsidedownandtheopenside
of the pressure seal pointing to the inlet side of the mo-
tor. Carefully install shaft into front cover.
7. Lubricatetheidlergearshaftwithcleanhydraulicoil.
Install idler gear shaft into the remaining position in the
