C-30HDG PUMP — GENERAL INFORMATION The following operating principles and operating suggestions should prove helpful in the successful operation of your concrete pump.Your new “small line” concrete pump has been designed to give you many years of service when operated properly. A study of the following paragraphs is important to the successful operation of your new Direct-flow Concrete Placer.
C-30HDG PUMP — HOW IT WORKS The C-30HDG concrete pump has one main pumping piston which is valved by means of two ball checks. (A inlet, and B outlet.) The secondary piston is used as a compensator piston to smooth out the pulsations of a single piston action. Note: The compensator will not start operating until material is pumped into the line and back pressure develops. The compensator spring, which is installed on the compensator piston rod, deflects with each piston stroke.
C-30HDG PUMP — HOW IT WORKS The pumping piston (Figure 11) is forcing the material past ball (B) and out to the nozzle, also seating ball A so that the material will not flow back to the hopper. This action also fills the compensating piston for the next stroke. Figure 11. Pumping Pistons Figure 12 shows the relationship between the return spring, the compensator spring and the rocker arm to maintain a smooth performance. DO NOT tighten the bolt (Item 1) completely, the rod end must be able to move.
C-30HDG PUMP — OPERATING INFORMATION C. If it is necessary to wait 10 minutes or more for another load of concrete, it is wise to start the pump and pump 6 or 8 strokes every 5 minutes to prevent setting of the mix in the system. If waiting time is excessive, it would be wise to wash out the pump and hoses and start over when the new truck arrives. OPERATING SUGGESTIONS 1. A well-planned location of the pump and routing of the hose before starting a pour may save subsequent moves throughout the job. 2.
C-30HDG PUMP — OPERATING INFORMATION WARNING - Hose Blockage Hazard If you repeatedly pull the throttle all the way out and try to force your pump to push through blockages due to separation of material in the hose or manifold, you will soon have breakdowns and costly repairs which are not covered under warranty. If a blockage occurs, find where it is and clear it before further pumping. DO NOT increase the engine speed to clear the blockage. Increasing the engine speed will only compound the problem.
C-30HDG PUMP — OPERATING INFORMATION 6. If a blockage occurs in a hose, “walk the hose” until you find the point of trouble.The hose will be soft immediately past the blockage. If this happens at the start, disconnect the hose at the first coupling past the blockage. Elevate the hose at that point with the blockage area hanging down.
C-30HDG PUMP — OPERATING INFORMATION Down-Hill Pumping Valve Seats Downhill pumping can be difficult on some jobs. It is suggested that a sponge 2”x 4”x 6” be placed in the hose before the start of pumping.Wet the sponge before placing it in the hose. Reference the Operating Suggestions at the start of this section for slurry procedures.
C-30HDG PUMP — OPERATING INFORMATION Cam Roller If the cam roller does not ride on the cam profile smoothly, it may be caused by insufficient line back-pressure; e.g., a wet mix with only 50 feet of hose. Add more hose as necessary. It can also be caused by cavitation or the passing of over-sized aggregates through the valving, causing it to skip. Snap-Joint When using Snap-Joint couplings with gaskets to join hose, see that they are washed clean after each job.
C-30HDG PUMP — INSPECTION CAUTION - General Saftey Guidelines NEVER operate the pump in a confined area or enclosed area structure that does not provide ample free flow of air. Engine Oil Check 1. To check the engine oil level, place the pump on secure level ground with the engine stopped. 2. Remove the dipstick from its holder (Figure 13) and wipe it clean. ALWAYS wear approved eye and hearing protection before operating the pump . NEVER operate the pumps's engine with the engine hood removed.
C-30HDG PUMP — INSPECTION Lubrication Box TABLE 5. OIL TYPE Season Temperature Oil Type Summer 25oC and greater SAE 10W-30 Spring/Fall 10oC to 25oC SAE 10W-30/20 Winter 0oC or Lower SAE 10W-10 Gasoline Check 1. Remove the gasoline cap located on top of fuel tank. 2. Handle Fuel in a safety container. If the container does not have a spout use a funnel. 3. Visually inspect to see if fuel level is low. If fuel is low, replenish with unleaded fuel.
C-30HDG PUMP — INSPECTION/STARTUP Checking Engine Coolant Level 1. Remove the radiator cap, and check the cooling water level inside the radiator (Figure 18). 2. Maintain water/coolant level at top of radiator coils. Make sure radiator overflow bottle is filled to the proper level. Figure 19. V-Belt Deflection Starting CAUTION - General Saftey Figure 18.
C-30HDG PUMP — STARTUP/SHUTDOWN PROCEDURES 3. Insert the ignition key into the ignition switch (Figure 22), turn the key to the ON position, then to the START position, release the key when the engine starts. 2. On the control box, place the pumping control switch in the REMOTE ON position (Figure 25) Figure 25. Pumping Control Switch (Remote) Figure 22. Ignition Switch 3. To begin pumping, place the toggle switch on the hand-held remote unit (Figure 24)in the pump ON position 4.
C-30HDG PUMP — MAINTENANCE (PUMP) Preventive Maintenance General Clean-up Procedure It is extremely important to maintain this pump due to the highly abrasive nature of concrete material. 1. Ensure that there is no blockage in the hose and line (Pumping Tips, step 8) or in the manifold (Pumping Tips, step 7). If a blockage exists, clear it to ensure proper operation the next time it is used.
C-30HDG PUMP — MAINTENANCE (PUMP) Sponge Clean-out Procedure Lubrication Box This section will explain the recommended procedure for using a sponge to clean out the hose lines. The C-30HDG model features a fully enclosed lubrication box, which utilizes the "SPLASH" method of lubrication. CAUTION - Clearing The Pump NEVER use muriatic acid to clear the pump. Acid will dissolve the chrome finish on the pumping cylinder. NEVER use compressed air to clean out the lines.
C-30HDG PUMP — MAINTENANCE (PUMP) Crankshaft and Cam Assembly Procedure Ball and Seat Replacement Procedure 1. Set bearing block (P/N EM14303) into hydraulic press. Place bearing cup into bearing block and press in evenly. Bearing cup should be aligned equally on both sides of bearing block. 1. Remove 3”x 2” reducer and 3” elbow from the pump outlet. Remove exhaust gate andY-manifold (secondary manifold). Check ball seat and ball stop pin for wear. If any wear is detected, the part should be replaced.
C-30HDG PUMP — MAINTENANCE (PUMP) Clutch Lining Replacement (For P/N EM14320 Clutch Assembly Only) The normal lining thickness measures 3/16 of an inch. If the clutch starts to slip or make an usual noise, it may be necessary to replace the lining. Please note that the lining retaining rivets should not be exposed to the rotating weight. The following procedure will assist you in replacing the lining. 1. Remove worn out lining and rivets. Check clutch springs and flyweights for wear. 2. Cut 1/8 in.
C-30HDG PUMP — MAINTENANCE (PUMP) Bearing Installation 1. Install the bearing components on the crankshaft making full contact with the back side of the crank disc as indicated the symbol #. See Figure 24 below. 2. Install the bushing in the cam weldment and slide it onto the crankshaft until contact is made with the bearing spacer. It is important that the Bearing Assembly is installed properly. 3. Tighten the 3 allen head bolts “A” while exerting pressure on the bushing towards the bearing spacer.
C-30HDG PUMP — MAINTENANCE (PUMP) 3. 1. After the bearing assembly has been is installed , remove the three “dog type” allen head set screws (B) to allow detents to be drilled. See Figure 25 below. If this procedure is not followed closely the heavy loading of the bearing during pumping operation causes the Timken™ cone bearings to create lateral forces which will move the taper bushing and allow the Timken™ cone bearings to separate from the race and subsequently fail.
C-30HDG PUMP — MAINTENANCE (PUMP) Figure 26. V-Belt and Drive Chain Adjustment V-Belt And Drive Chain Adjustment 1. Loosen the pillow bearing bolts (Figure 26) only to the point where the bolts will remain snug. 2 Unlock the two pusher bolt lock nuts. 3. Turn each pusher bolt clockwise an equal amount until the chain is to proper adjustment of approximately 3/8 to 1/2 in. slack in the chain.
C-30HDG PUMP — MAINTENANCE (PUMP) Roller Chain Application Installation and Drive Alignment A properly selected, installed and maintained drive chain (Figure 27) is an extremely versatile means of power transmission. It is possible, however, to greatly reduce a chain’s life and even induce failure if the chain is abused through improper installation, operating or maintenance procedures. In certain applications, failure can lead to personal injury or property damage.
C-30HDG PUMP — MAINTENANCE (PUMP) Drive Chain Lubrication As a chain articulates in entering and leaving a sprocket, there is relative movement between pin and bushing surfaces. These surfaces wear causing chain elongation. If a lubricant film can be maintained between the pin and bushing, the wear rate is very slow and the chain wear life very long. Maintaining the oil film is relatively simple at low speeds but becomes increasingly difficult as the speed increases.
C-30HDG PUMP — MAINTENANCE (PUMP) Assembling and Disassembling Drive Chain CAUTION - DRIVE CHAIN SAFETY You may be seriously injured if you attempt to install the drive chain while the pump is running. Turn OFF the engine and lock out gears and sprockets before attempting installation. Once installed, the drive chain must be guarded to prevent personal injury or properly damage in the event the chain separates during operation. NEVER run pump with drive chain guard removed.
C-30HDG PUMP — ENGINE TROUBLESHOOTING Practically all breakdowns can be prevented by proper handling and maintenance inspections, but in the event of a breakdown, please take a remedial action following the diagnosis based on the Engine Troubleshooting (Table 6) information shown below and on the proceeding page. If the problem cannot be remedied, please leave the unit just as it is and consult our company's business office or service plant. TABLE 6.
