Werkzeuge
-
-
Place the spacer collar around the pump rod below the raised chain, with the beveled side down, and the flat side facing up.
-
-
-
Lift the pump handle until the base of the chain comes to rest on the spacer collar, and the chain is slack. Hold the handle in this position while the chain is being detached.
-
-
-
Using the two access holes, place an angled socket wrench on the bolt and nut attaching the chain to the pump handle.
-
-
-
Remove the two bolts from the handle side of the pump head.
-
Use one wrench on the bolt and another on the nut beneath. Hold the bolt stationary and loosen the nut.
-
-
-
After removing the two handle side bolts, have your partner support the weight of the handle.
-
Remove the two remaining bolts in the same fashion.
-
-
-
Slightly twist the head flange, until the corners overhang the top of the tank far enough to grab.
-
-
-
Unscrew the chain from the top of the pump rod.
-
Remove the chain.
-
Check the chain for signs of wear or damage.
-
-
-
Have one team member lightly pull up on the T-handle, while another loosens the rod clamp. This will prevent damage to the pump.
-
-
-
Use the T-handle to rotate the entire pump rod clockwise several full turns.
-
Keep turning until the resistance greatly increases. The foot valve will provide this resistance when fully screwed into the traveling valve base.
-
-
-
Replace the rod clamp on the base of the pump.
-
Tighten the rod clamp against the pump rod.
-
-
-
Make sure there is at least 6 inches of space between the joint and the rod clamp to allow yourself enough room to work. If necessary, continue pulling the rod out of the well before tightening the rod clamp to ensure sufficient spacing.
-
-
-
Use two wrenches to loosen the joint between the top section of pump rod and the rest of the pump rod.
-
-
-
Separate the top section of pump rod from the joint.
-
Lift up the top section of pump rod and remove it.
-
Set the section of pump rod in a sanitary place, and remove the T-handle from the top.
-
-
-
Screw the jam nut and T-handle onto the top of the remaining section of pump rod still in the well.
-
Tighten the T-handle against the jam nut.
-
-
-
Lift the pump rod and valves straight up out of the well.
-
Set the rod aside, taking care to keep the valves clean and off the ground.
-
To reassemble your device, follow these instructions in reverse order.
