LS600 PUMP — MAINTENANCE (PUMP)

CHANGINGTHE WEAR PLATE AND RING

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.

Wear Plate and Ring Replacement Procedure

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” 1-¼” bolts that hold the shuttle tube to the nun-plate and remove shuttle tube.

Using two small pry bars remove the rubber energizer ring, steel insert ring and wear ring.

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.

6.Clean out all concrete build up in and around the nun- plate area with a wire brush.

7.Inspect the wear components for indications of wear. The wear plate has two wear surfaces.

Wear Plate Installation

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.

Wear Ring installation

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.

After installing the above mentioned components the machine can be reassembled by reversing steps 1 through 5 of the Wear Plate and Ring Replacement Procedure.

HEAT EXCHANGER COOLING FAN

This section is intended to make sure the fan is working properly. Under normal conditions the fan should be running any time the engine is turned on.

CAUTION - HYDRAULIC OILTEMPERATURE

If the hydraulic oil temperature exceeds 170 degrees Fahrenheit, shut down the pump. DO NOT continue to operate the pump. Failure to shut down the pump will result in severe damage to the pump.
