Remove snap ring (2) from the rotor seal housing (8) using internal-type snap ring pliers. 2. Remove rotor (3) from the housing (8). 3. Remove floating seal (4), O-ring (5), seal guide (6) and spring (7) from shaft inside the housing (8). 4. If leakage is noted, replace the rotor and seal assembly which are available in a repair kit (GG- 190-20654). ASSEMBLY OF ROTOR UNION Follow steps of disassembly in reverse (see above). Fig. 14-Aligning Drive Belt Place a straight edge along the fixed half of the drive sheave extending it toward the driven sheave but not touching the driven sheave. Clamp it to the drive sheave. Place another straight edge along the fixed half of the driven sheave but not touching the drive sheave. Clamp it to the driven sheave. Measure the distance between the two straight edges at both ends. Both measurements should be 2-3/4 inches (6.98 cm). INSTALLATION OF ROTOR UNION Follow steps of removal in reverse (see page 50-20-3).
