Disassembling Lower Valves | Sterling 882.00379.00 specification

Disassembling Lower Valves

1.Remove the pipe nipple and pipe coupler from the lower cap.

2.Remove the two (2) socket cap screws from the lower cap.

3.Remove the lower cap from the machined body.

4.Remove the six (6) socket cap screws from the end plate. Separate the end plate from the machined body.

5.Remove the cotter pin from the plunger. Unscrew the plunger from the air cylinder shaft.

6.Remove the four (4) socket cap screws holding the air cylinder to the end plate.

Servicing and Reassembling Lower Valves

1.Clamp the air cylinder in a vise and unscrew the end cap. Using parts from the valve service kit, replace the seals in the air cylinder. Screw the end cap back on.

2.Secure the air cylinder to the end plate using the four (4) socket cap screws.

3.Screw a new plunger on the air cylinder shaft; secure it with the cotter pin.

4.Place a new gasket on the end plate; secure the end plate to the machined body using six (6) socket cap screws.

5.Fasten the lower cap to the air cylinder using two (2) socket cap screws, a new gasket, and a new O-ring.

6.Screw the pipe nipple and coupler back into place.

Reinstalling Lower Valves

1.Replace the O-rings in the machined body.

2.Position the valve on the vacuum power unit. Tighten the set screws that secure the valve to the blower outlet.

3.Reconnect the valve to the T-Y tube by sliding the radiator hose back into place. Tighten the hose clamps.

4.Reconnect the copper compressed air tube to the fitting on the lower valve.

5.Push the discharge silencer into the valve body, and secure it with the screws. On units with optional sound enclosures, push the short silencer into the valve body, reinstall the U-bend, and secure both ends with the radiator hose and hose clamps.
