7.  Remove the three 3/8 – 16 x 3” bolts from the piston. 

Remove the front faceplate.

8.  Install two the 3/8’ 16x3” bolts back  into the piston – do 

not tighten. Use the two bolts as leverage to remove 

the rubber piston cup  and rear components.

9.  Obtain two 3/8 16x7” full thread studs  (these studs will 

be used to assist in assembly  alignment) insert the 

two studs into the piston adapter. Coat the concrete 

cylinder with grease.

10.  Install the “O” Ring around the oiler plate. Install the 

plate into the concrete cylinder utilizing the studs for 

alignment.

11.  Install the felt holder over the oiler plate. Install felt ring  

into felt holder.  Install the bronze ring.

12.  Using silicon sealant place a small bead of sealant 

material on the front of the rubber piston cup and the 

rear of the face plate. Install over alignment studs and 

into concrete cylinders.

13.  Insert one 3/8” 16x3” bolt into the open bolt hole, 

remove the alignment studs one at a time and install 

the remaining 3/8” 16x3” bolts.

Due to the swinging motion of the 

nun-plate and the 

abrasive nature of concrete, it is normal for the cutting 

ring to wear on the side that shears through the concrete 

inside the hopper. 
If the wear ring and wear plate do not fully seat against each 

other the concrete slurry will pump into the hopper. This 

condition can be easily observed by the sudden change of 

the level of concrete inside the hopper during each stroke.

Felt ring must be saturated with 30 wt. oil prior to 

installation.

Before installing 3/8” bolts, coat the back of bolt heads 

with silicon sealant. Torque all three bolts equal at 55 ft. 

lbs. each.

1.  Remove the two hydraulic hoses connected to the 

remix motor. Plug the ports with fittings (not provided) 

to prevent hydraulic hose leakage.

2.  Remove the hopper discharge nipple and loosen sleeve 

seal. Inspect and replace if wear is excessive.

3.  Remove the two tie rod nuts and the four eyebolt nuts 

securing the hopper to the pump frame.

4.  Using an approved lifting device, remove the hopper 

using extreme care not to damage the hopper seal.

5.  Remove the four 1/2” 1-1/4” bolts that hold the shuttle  

tube to the nun-plate and remove shuttle tube. 

6.  Using two small pry bars remove the rubber energizer 

ring, steel insert ring and wear ring.

7.  Clean out all concrete build up in and around the nun-

plate area with a wire brush.

8.  Inspect the wear components for indications of wear. 

The wear plate has two wear surfaces.

1.  Install the two cylinder 

o-rings.

2.  Using silicon sealant, coat the circumference of the 

concrete cylinders, the back of the wear plate and 

around the five bolt holes. Next, install the wear plate 

and the five bolts. The bolts must all be equally snugged 

and tightened to 100 foot pounds each. 

1.  Install the wear ring into the 

nun plate.

2.  Install the steel insert ring inside of the rubber energizer 

ring.

3.  Install the energizer ring assembly into the nun plate. 
4.  After installing the above mentioned components 

the machine can be reassembled by reversing steps 

1 through 5 of the Wear Plate and Cutting Ring 

Replacement Procedure.

The energizer ring and wear ring will normally have 

concrete contamination holding them in position. It will 

be required to chip some of the concrete loose to better 

expose the energizer ring.
