Apex Seal Warpage

Replace if the clearance exceeds limits.
3) Using a feeler gauge, check gap between apex seal and
groove in rotor. Feeler gauge should be inserted until tip of feeler
gauge reaches bottom of groove.
4) Standard clearance is .0020-.0035" (.05-.09 mm). Replace
apex seal if gap exceeds .0059" (.15 mm). Check seal spring height as
shown in Fig. 16. Replace spring if free height is less than .2165"
(5.5 mm).

Measuring Free Height of Apex Seal Spring

Height must be more than .2165" (5.5 mm).

Side Seal

1) Remove all carbon from side seal and spring. Check side
seal protrusion from rotor surface, and confirm free movement by
pressing with finger. Protrusion should be more than .02" (.5 mm).
2) Check gap between side seal and groove with a feeler
gauge. Standard gap is .0012-.0031" (.03-.08 mm). If wear limit of .
004" (.10 mm) is measured, replace side seal.
3) Check gap between side seal and corner seal with seals
installed on rotor. Insert feeler gauge between end of side seal
(against rotating direction of rotor) and the corner seal. If gap
exceeds .016" (.4 mm), replace side seal.
4) When side seal is replaced, adjust gap between side seal
and corner seal by grinding one end of side seal along round shape of
corner seal, using a fine file. Adjust gap .002-.006" (.05-.15 mm).

Corner Seal

1) Clean carbon from corner seal. Check corner seal
protrusion from rotor surface, and check free movement by pressing
with finger. Protrusion should be more than .02" (.5 mm).
2) Extent of corner seal groove wear is determined by using
