Oil Seal

Fig. 28 Stopper Hole Of Oil Seal Ring:

Fig. 29 Installing Oil Seal Springs:

1. Place the rotor on a rubber pad or cloth.
2. Install the oil seal springs in their respective grooves on the rotor with each round edge of the spring fitted in the stopper hole in the oil seal grooves as shown in Fig. 28. The oil seal springs have been painted in cream or blue color. The cream-painted springs should be fitted on the front faces of both front and rear rotors. While the blue-painted springs should be fitted on the rear faces, Fig. 29.
3. Install a new O-ring in each oil seal.
4. Place the inner oil seal in the oil seal groove so that the square edge of the spring fits in the stopper notch of the oil seal.

Fig. 30 Installing Inner Oil Seal:

5. Press the inner oil seal by using a used inner oil seal so that the lip surface of the oil seal sinks into a position approximately 0.016 in. (0.4mm) below the surface of the rotor, as shown in Fig. 30.
6. Place the outer oil seal to the oil seal groove so that the square edge of the spring fits in the stopper notch of the oil seal.
7. Push the oil seal slowly with fingers. When replacing the oil seal, confirm the smooth movement of the oil seal by placing the oil seal on the oil seal spring in the groove before inserting the O-ring. Be careful not to deform the lip of the oil seal.
8. Apply sufficient engine oil onto each oil seal, and confirm the smooth movement of each oil seal by pressing the oil seal.
9. Install the oil seal springs and oil seals on the other side of the rotor.
