Side Seal & Spring

Fig. 24 Checking Side Seal Clearance:

Fig. 25 Checking Side Seal To Corner Seal Clearance:

1. Check the free movement of the side seal in the rotor groove by pressing with finger.
2. Check the side seal protrusion from the rotor surface and replace the side seal spring if the protrusion is less than 0.02 in. (0.5mm).
3. Check clearance between side seal and the groove with a feeler gauge, Fig. 24. Standard clearance is .0011-.0031 inch (.03-.08mm). If clearance exceeds .0039 inch (.10mm), replace side seal.
4. Using a feeler gauge, check the clearance between the side seal and the corner seal with these seals installed on the rotor, Fig. 25. If the clearance exceeds 0.016 in. (0.4mm), replace the side seal. When the side seal is replaced, adjust the clearance between the side seal and the corner seal by grinding the one end of the side seal along the round shape of the corner seal with a fine file so that the clearance will be 0.002-0.006 in. (0.05-0.15mm).
