or 204 to 264 lb-in. for nuts used on 7/16 in. fine threaded shafts.
10.Clean the old body gasket from the volute.
11.Put a new body gasket on the bearing assembly and then install the assembly on the

7. Replace the conduit box cover.
8. Check for proper motor rotation. The proper rotation is clockwise when viewed from
the back of the motor.
6.3.4 Reinstall the elastomeric type coupler and motor
1. Position the coupler half on the pump shaft:
If your pump shaft... Then...
Contains a dimple Locate the coupler half on the shaft so that a coupler setscrew is positioned over
the dimple. Tighten the setscrew so that it seats in the dimple. Tighten the
other setscrew if there is one.
Is keyed and uses a size 3J
coupler
Slide the coupler half on the shaft. Do not tighten the setscrew.
Is keyed and uses a size 4J
coupler
Slide the coupler half onto the shaft so that the shaft end extends 0.25 in. (0.64
cm) past the coupler half flange face. Tighten the setscrews.
Is keyed and uses a size 5J
coupler
Slide the coupler half onto the shaft so that the shaft end is flush with the
coupler half flange face. Tighten the setscrews.
2. Position the coupler half on the motor shaft:
If... Then...
The motor shaft contain a
dimple
Locate the coupler half on the shaft so that a coupler setscrew is positioned over the
dimple. Tighten the setscrew and make sure it seats in the dimple. Tighten the other
setscrew if there is one.
The motor shaft is keyed Slide the coupler half onto the motor shaft. Do not tighten the setscrews.
3. Place the new insert in the pump side coupler half.
4. Lift the motor into position, align the insert and motor coupler half, and then bolt the
