Place one wrench on the top of one of the pump riser plate bolts.
Place another wrench around the bottom of the bolt.
Pull the wrenches apart to loosen the bolt.
Repeat this procedure for the remaining three bolts.

Modifier

Étape 15

Remove the four nuts and bolts securing the pump riser plate, and store them in a sanitary container such as a bucket.

Modifier

Étape 16

Rotate the pump plate 45 degrees. This will allow for a better grasp when lifting the plate.

Modifier

Étape 17

Bush Pump Cylinder Replacement: étape 17, image 3 de 3

Securely lift the T-handle several inches.
While 2 people support the T-handle, remove the pump rod clamp.
Lower the T-handle gently until the pump rod is supporting itself.

Modifier

Étape 18

Bush Pump Cylinder Replacement: étape 18, image 3 de 3

This particular pump is using a tripod with a block and tackle to lift the riser main. C-wrenches may also be used to lift the riser main.
Securely clamp and tighten the pipe elevator to the riser main below the spout exit.

Modifier

Étape 19

Being careful not to let the rope slip, use the block and tackle to lift the riser main until the pipe elevator reaches the block and tackle.

Modifier

Étape 20

Bush Pump Cylinder Replacement: étape 20, image 3 de 3

Once the riser main has reached the block and tackle, tighten the base clamp against the riser main.

Modifier

Étape 21

Bush Pump Cylinder Replacement: étape 21, image 3 de 3

Secure the base clamp to the frame base using a bolt.
One bolt is typically sufficient to keep the base clamp in place, but you can add another bolt if you wish to further secure it.

Modifier

Étape 22

Bush Pump Cylinder Replacement: étape 22, image 3 de 3

While supporting the top portion of the pipe, carefully move the elevator clamp off of the pipe.
Lower the elevator clamp while providing tension towards the ground to prevent the ropes from tangling in the block and tackle.

Modifier

Étape 23

Bush Pump Cylinder Replacement: étape 23, image 3 de 3

Attach and tighten the elevator clamp to the riser main as close to the bottom as possible.

Modifier

Étape 24

Once the elevator clamp is tight, provide tension on the rope.
While keeping tension on the rope to support the riser, loosen the base clamp.

Modifier

Étape 25

Bush Pump Cylinder Replacement: étape 25, image 3 de 3

Use the rope to pull the riser main up as far as comfortable.
Be sure to keep the rope within the confines of the tripod to prevent the tripod from pulling over.
Watch the top of the tripod to align the riser main in the support slot.

Modifier

Étape 28

Remove the elevator clamp from the riser main, and secure it to the tripod to keep it out of the way.

Modifier

Étape 29

Keep the pipe wrench a few inches above the joint in this step.
Using a pipe wrench, unscrew the first section of the riser main from the connection.

Modifier

Étape 30

Bush Pump Cylinder Replacement: étape 30, image 3 de 3

Secure a splash guard over the joint to prevent water from spraying out of the connection when separated.
Using the pipe wrench, loosen the riser main until water begins to spray into the splash guard.
Do not loosen it any further until the water has stopped spraying.

Modifier

Étape 31

Bush Pump Cylinder Replacement: étape 31, image 3 de 3

Remove the splash guard, and finish loosening the riser main.
Remove the first section of the riser main by lifting it straight up, while supporting the top of the section and keeping the pipe within the support slot on the top of the tripod.

Modifier

Étape 32

Bush Pump Cylinder Replacement: étape 32, image 3 de 3

Attach and tighten the rod clamp a few inches below the first pump rod connection.

Modifier

Étape 33

Bush Pump Cylinder Replacement: étape 33, image 3 de 3

When the joint is separated, carefully lower the riser main to the ground.

Modifier

Étape 34

Bush Pump Cylinder Replacement: étape 34, image 3 de 3

Carefully lower the riser main, horizontally, and place it in a sanitary place, preferably resting above the ground, to prevent contamination.

Modifier

Étape 35

Bush Pump Cylinder Replacement: étape 35, image 3 de 3

Remove the T-handle from the separated pump rod.
Attach the T-handle to the remaining pump rod.
Remove the rod clamp and repeat steps 29-35 until the riser main is completely removed, or until the broken section is reached.
