Rotor Housing

1) Inspect rotor housing for signs of water or gas leakage.
Check for wear or damage to rotor running surface or stationary gear.
Check main bearings for signs of scoring or flaking.
2) To clean housing, wipe off sealing agent or carbon in
rotor running surface with a rag and ketone or thinner. Remove rust
deposits in water cooling passages.
3) Inspect for cracks or damage to chromium-plated surface.
Check for signs of gas or water leakage. Housing must be replaced if
any of these conditions exist.
4) Place a straightedge across sealing surface of rotor
housing and check for distortion with a feeler gauge. If distortion
exceeds .0016" (.04 mm), replace housing. See Fig. 10.

5) Check rotor housing thickness at points A, B, C, and D in
Fig. 11. If micrometer readings vary between point A and minimum value
for B, C, and D by more than .0024" (.06 mm), replace rotor housing.
