Maintenance (Continued)126412A101Install the impeller2. Mark the shaft and sleeve at the face of the seal chamber.3. Continue the complete reassembly of the pump, except for the mechanical seal.4. Set the impeller clearance.Refer to the Impeller clearance setting section for more information.5. Scribe a line on the marked shaft and sleeve at the face of the seal chamber.6. Remove the casing, the impeller, and the seal chamber.7. Install the mechanical-seal rotary unit per the manufacturer's instructions.Use the scribed line as the seal-reference dimension. Be sure to secure the rotary unit in place usingthe set screws in the locking ring.8. Install the gland, with the stationary seat and gland gaskets installed, on the seal chamber.9. Reinstall the seal chamber.10. Complete the reassembly of the pump.CAUTION:Wear heavy work gloves when you handle impellers. The sharp edges can cause physical injury.1. Install the impeller.Pump sizeSTi, MTi, and LTiActionInstall the impeller (101) with an O-ring (412A).2. Attach a shaft wrench and a coupling key on the shaft.a) When the impeller (101) makes firm contact with the sleeve (126), raise the shaft wrench(counterclockwise, viewed from the impeller end of the shaft) off of the bench and slam it down(clockwise, viewed from the impeller end of shaft).b) Apply a few sharp raps to tighten the impeller (101).106 Model 3796 i-FRAME Installation, Operation, and Maintenance Manual
Maintenance (Continued)1013. Loosen the clamp bolts (370C) and the jack bolts (370D).4. Measure the gap between the impeller (101) and the seal chamber and stuffing-box cover (184) with afeeler gauge.423370C370D5. When you reach a 0.030 in. (0.76 mm) clearance, tighten the clamp bolts (370C), jack bolts (370D),and lock nuts (423).This approximates the impeller position when it is set to 0.015 in. (0.38 mm) from the casing. Performa final impeller adjustment after you install the impeller into the casing.6. Check the impeller (101) runout.Check vane tip to vane tip. If the total indicator reading is greater than 0.005 in. (0.13 mm), determinethe cause and correct the issue before you proceed.Model 3796 i-FRAME Installation, Operation, and Maintenance Manual 107
