Vane clearance.

Check vane clearance between vanes and rear end plate (Fig. 14). The clearance must be between 0.004" and 0.006". This may be adjusted by the use of extra shims.

Replace casing.

Care must be taken to ensure that the casing is replaced the correct way round for the rotation required (see next page).
Ensure that the dowel in the casing registers in the end plate, care being taken to replace the casing squarely (Fig. 15), to avoid damage to vanes and casing bore.
