1. Install bearing (4), spacer (3) and bearing (2) on shaft (8).2. Put retainer (1) and gear (7) in position on the shaft assembly. Install retainer (6) and bolt (5). 3. Use tooling (A) to install the lip seal in the housing as shown. Put a small amount of clean SAE 30 oil on the lip of the seal. 4. Install a new O-ring seal (10) on the housing.5. Put shaft assembly (9) in position in the housing. Install the bolts that hold the retainer to the housing.
Clean water only is permitted for use as a lubricant for assistance at installation. Do not damage or put hands on the wear surface of the carbon ring or the ceramic ring. Install the ceramic ring with the smoothest face of the ring toward the carbon seal assembly.
6. Put ceramic ring (12) in position in rubber seal (11). Use hand pressure and the tool (which is with the replacement ring) to install the ceramic ring in the housing. 7. Remove the spring from seal assembly (13). Use hand pressure and the tool (which is with the replacement ring) to install the seal assembly. Push the seal assembly on the shaft until the seal faces make light contact. 8. Install spring (15) on the shaft.9. Put impeller (14) in position on the shaft. Install the washer and bolt that holds it. Tighten the bolt to a torque of 39 3 N m (29 2 lb.ft.). 10. Install O-ring seal (17) on the outside diameter of the adapter.
