INSTALLATION

1. Slide the motor coupling flange (figure 3, item 2) onto the motor shaft (figure 3, item 7) with the small end

towards the AFFF pump motor (figure 3, item 3).

WARNING

Heavy loads can crush. Do not allow any body parts to come under the load or

between the load and a stationary object. Death or serious injury can result.

2. Use a sling and chain hoist to position the AFFF pump motor (figure 3, item 3) on its foundation with the

mounting holes aligned.

3. Install four bolts (figure 3, item 4), four new lockwashers (figure 3, item 5), and four flat washers (figure 3,

item 6). Do not tighten at this time.

4. Align the pump coupling flange (figure 3, item 8) and the motor coupling flange (figure 3, item 2) together

ensuring parallel and angular alignment as shown in figure 4.

NOTE

Correct alignment of the pump coupling and motor coupling is shown in detail A of figure

4. Parallel misalignment and angular misalignment are depicted for reference only in

details B and C, respectively.

5. Once the pump coupling flange (figure 3, item 8) and the motor coupling flange (figure 3, item 2) are correctly

aligned per detail A of figure 4, tighten the motor coupling flange setscrew (figure 3, item 1), and the four bolts

(figure 3, item 4).

NOTE

The coupling alignment may change after tightening the mounting bolts. Always re-

check the coupling alignment following fastener tightening.

6. Check the coupling alignment. If the alignment is not correct, repeat steps 4 and 5.

7. Install the coupling cover (figure 2, item 4) and secure it with two bolts (figure 2, item 1), two flat washers

(figure 2, item 3), and two new lockwashers (figure 2, item 2).

8. Connect the electrical wiring (figure 1, item 5) using the labels from step 4 of Removal as a guide. Remove

the labels.

9. Install the junction box cover (figure 1, item 2) and secure it with the two screws (figure 1, item 1).

10. Remove the lockouts and tagouts (FM 55-502).

11. Set to ON the AFFF PUMP circuit breaker on the main switchboard.
