Promethean Boilers, Model 4WI Manual
Remember that alignment in one direction may alter alignment in another. Re-check both angular and parallel align-
ment procedures after making any alteration.
A properly aligned coupling will last longer and will provide trouble-free mechanical operation.
8.17.8 — Air Compressor Replacement
Refer to Chapter 9 for identification of various components and use the following procedures when replacing the
pump. Be sure to tag the motor leads if disconnected to simplify reconnection.
8.17.8.1 — Dismantling
1.
Lift out the two front cylinder pins that hold the screen, and remove the screen.
2.
Disconnect the flared nut on tubing “A” (behind screen) (see Figure 8-31) and lift tubing “A” high enough to
prevent drainage of lubricating oil from the tank.
FIGURE 8-31.
Air Pump Components
3.
Disconnect the flared nut at the orifice fitting.
4.
Remove the two sheet metal screws that hold the cylinder in place. One screw is located at the top rear of the
cylinder, the other is at the bottom front.
5.
Remove the entire heat exchange assembly, consisting of the cylinder, the finned tubing, and the oil line “B”.
6.
Remove the fan from the air pump.
7.
disconnect the flexible air line from the lube tank.
8.
Remove the coupling guard by pushing in on both sides until it clears the clamp.
9.
Loosen the clamp at the rear of the tank and remove the tank with copper tubing “B” attached.
10.
Leave the rear pump bracket (coupling end) in place to aid in realignment of the replacement pump. Do this by
removing the two capscrews that extend through the bracket into the pump housing. Temporarily leave the
front bracket attached to the pump.
