3. Measuring Method.

a. Do not force the gauge into the groove.

b. Gauge should be put vertically into the groove.

 

**Note:   An oversize Corner Seal for the expansion type corner seal is not available. However, the standard size corner seal of the expansion type can also be used for class- "b" (go-end of the gauge can only go into the groove). If both ends of the gauge go into the groove (class - "c"), replace the Rotor.

7. Side Seal.

7.A Gap between Side Seal and Corner Seal (delta-E).

 

1. Measuring tools required:  Feeler Gauge (0.05 and 0.4 mm).

2. Measurement of delta-E.

8. Oil Seal.

8.A Width of Oil Seal surface contacting Side Housing.

 

1. Measuring tools required: a. Magnifying glass      b. Vernier Calipers (0 - 150 mm).

2. Measurement of A.

 

 

8.B Chipping of Chromium edge.

Replace if A is more than 2.5 mm (0.1 in) or the number of surface chips exceeds 10.

Replace if A is more than 2.5 mm (0.1 in) or the number of surface chips exceeds 10.

 

 

Note: When installing the inner Oil Seal, utilize an old Oil Seal as shown in the figure to fully seat the Oil Seal:

9. Seal Spring.

9.A Stroke of Seal Spring.

 

1. Measuring tools required: Vernier Calipers (0 - 150 mm).

2. Measurement of stroke A, B, C and height D.

9.B Thickness of Seal Spring.

 

Inspection: Visual Inspection.

A, B, C, D    -   Replace spring if less than half of new one.

10. Eccentric Shaft.

10.A Eccentric Shaft runout.

 

1. Measuring tools required: a: "V" Blocks      b: Dial Indicator and stand      c: Flat Surface

2. Runout of point A. Replace if Runout is more than 0.06 mm (0.0024 in).

10.B Bearing clearances.

10.B.a Rotor Bearing clearances.

 

1. Measuring tools required: a: Micrometer (50 - 75 mm)      b: Inside Micrometer (50 - 75 mm)

2. Measurement of point a, b, and c.

    Rotor Bearing Clearance = (c - a) or (c - b)

If the Rotor Bearing clearance is more than 0.1 mm (0.0039 in), replace the eccentric shaft or the Rotor Bearing.

10.B.b Main Bearing clearance.

 

1. Measuring tools required: a: Micrometer (25 - 50 mm)      b: Inside Micrometer (25 - 50 mm)

2. Measurement of a, b, and c.

    Main Bearing Clearance = (c - a) or (c - b)

If the main bearing clearance is more than 0.10 mm (0.0039 in), replace the eccentric shaft or Main Bearing.
