Rotor Housing, Rotary Engine

Fig. 17 Checking Rotor Housing Width Points:

1. Check the chromium plated surface on the rotor housing for scoring, flaking or any damage. If any of these conditions exists excessively, replace the rotor housing.
2. Check the rotor housing width at points close to the trochoid surface by using a micrometer. The measurements should be taken at four points, as shown in Fig. 17. If the difference between the value of point A and the minimum value among the points B, C and D exceeds 0.0024 in. (0.06mm), the rotor housing should be replaced with a new one.
