BELT CHANGE / GAS STRUT CHANGE PROCEDURE

MOISTURE SEPARATOR MAINTENANCE

The moisture separator will operate indefinitely under normal working conditions, however at some time it may be necessary to replace the

seals should the housing leak.

1. Isolate the housing from the air supply.

2. Fully depressurize in drain bowl as appropriate.

3. Unscrew bowl and remove. If pressure has not been completely released from the housing, air will escape from the warning hole giving an audible alarm. Screw back bowl and repeat instruction 2 before attempting again. Should resistance to unscrewing be experienced,

provision is made for a ’C’ spanner to fit onto the ribs of the bowl.

4. Check condition of bowl seal and replace if necessary. Clean screw threads.

5. Refit bowl with ’O’ ring seal.

6. Repressurize and check for leaks. If leaks occur they will most probably be from the bowl ’O’ ring. Depressurize housing and remove ’O’ ring as stated above and inspect and clean. Ensure that mating

surfaces are clean and then refit ’O’ ring and repressurize.

A.Gas strut.

B.Support bracket (part of pivoted assembly).

C.Tension cam.

1.Stop the machine, electrically isolate and vent all trapped pressure.

2.Remove the side cover from the machine.

3.Fit a 1/2” square drive wrench in the tension cam located above the airend (access from front door). Turn clockwise 1/4 turn to Position II to release gas strut tension on the belts.

4.Using a small screwdriver under the spring clip, ease the ball ends off the spherical studs at the ends of the gas strut.

5.Replace the gas strut and the studs at the same time by removing and replacing the studs then pushing the new gas strut firmly onto the studs until it clicks into place.

6.Turn the tension cam clockwise 1/4 turn to Position III to raise and support the airend. Place a block of wood or similar under the separator tank for support.

7.Replace the belts from the left side of the machine.

8.Turn the tension cam counter–clockwise 1/2 turn to Position I to tension the gas strut.

9.Spin the drive to check alignment of the belt ribs on the pulleys (sheaves).
