Illustration 1 g00633265
Typical example
Install Tooling (A) into the rear of the crankshaft.
Make sure that the arrow on the crankshaft adapter will point in the direction of the crankshaft rotation when the crankshaft adapter is installed. Attach a suitable lifting device to crankshaft adapter (1). Lift the crankshaft adapter onto Tooling (A). The crankshaft adapter weighs approximately 77 kg (170 lb).

Install Tooling (B) into two of the holes in the rear housing. Bolts (3) for the adapter of the crankshaft seal will be installed in these holes later.
Place a new wear sleeve into Tooling (C). Make sure that the arrow on the outside of the wear sleeve will point in the direction of the crankshaft rotation when the wear sleeve is installed.
Apply Tooling (F) to the inside diameter of the wear sleeve.
Place Tooling (C) and the wear sleeve onto Tooling (B). Install Tooling (D) and Tooling (E) onto Tooling (B) .
Tighten the nuts for Tooling (E) evenly in order to press the wear sleeve onto the crankshaft adapter. Press the wear sleeve onto the crankshaft adapter until the wear sleeve contacts the shoulder of the adapter.

Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The Tooling (A) is packaged with the new seal and adapter assembly. The seal installer helps to protect the seal. If the seal installer is separated from the seal prior to installation of the seal, the seal can be easily damaged. Do not remove the seal installer from the seal.Note: Do not apply any lubricant to rear seal (2). Do not touch the rear seal when you handle the adapter and seal assembly.

Typical example
Install two 3/8-16 NC guide bolts (5) into the rear housing.
If a seal is installed on the wrong end of the crankshaft, the seal will fail. Each end of the crankshaft requires seals of different part numbers. Make sure that the correct seal is installed on each end of the crankshaft.
