How do I inspect the shift tower for an air leak?

To check for air leaks in the shift tower, unplug the two airlines from the air cylinder on the pump. Cap off the air, be sure not to mix up the proper fittings lines came out of. After capping off ends, operate the up/down control to confirm if air leak stopped. If air has stopped, O-rings in cylinder or pump may need to be replaced. If valve still leaks then O-rings in shift tower may need to be replaced.

Loading Ramp

What are the proper steps to operate my loading ramp?

Make your heavy-duty Loading Ramp last longer with these key operational procedures.

Check the discharge gauge – it should be around 1100 to 1200 PSI.

Check the floor gauge – it should be around 500 to 600 PSI.

Adjust the floor’s flow control to achieve 1100 to 1200 PSI on the discharge gage – the PSI will vary on feed type.

As the bin empties, the pressure will drop on gauges – this is how you will know to open the next bin.

Once all bins are empty, Push floor off.

Push paddle boom off Push lower and in to place the paddle boom back in the saddle.

Make sure to close all bottom doors.

What is the optimal pressure for the discharge on a Paddle Wagon?

Pressure for the discharge should be around 1,100 to 1,200 PSI for optimal flow.

What is the optimal pressure for the floor on a Paddle Wagon?

Pressure for the discharge should be around 500 to 600 PSI for optimal flow.


Where are the extra fuses for the PTO stored?

If equipment is mounted on a truck, any extra fuses will be placed in the battery box.

How often should I inspect the PTO?

The PTO should be checked during the pre-operation inspection. Bolts on the PTO should be tightened monthly according to the Capscrew Marking and Torque Values Chart.


How do I operate a Ledwell Rollback?

Watch this or read below to operate your Ledwell Rollback correctly to extend the life of the bed.

To get started, walk around the entire truck to inspect the following: Hydraulic & Air Hoses, Winch & cable system, Lights, Flooring, and Wheels & Tires. Make sure the truck is on level ground.

Alternate sliding and adjusting angle of bed until firmly on the ground Load Equipment and remember to set the parking brake.

Secure equipment to the rollback with preferred tie-downs.

Be sure each piece is tied down at four points to secure properly.


To unload, reverse the process.

Why is my bed noisy and loose when operating?

Your bed moves and is supported on Nylontron bearing pads located on the main bed rails both inside and outside the flanges. These require a liberal greasing of both the flanges and center web of the beam and truck frame rail top pads with NLGI G#2 specification waterproof grease monthly. A small paint roller works well for this. When the truck receives PM that is a good time to grease all points.

Why does my bed operate slowly and stall out against a load?

Your truck has a 17GPM Hydraulic pump set to produce 2100 PSI at the relief. Slow operating and stalling are signs your pump may be getting weak. A weak pump will not produce enough flow or pressure because it is bypassing internally which will make the oil heat up more than normal. Staling could also mean you are overloaded if you hear the pressure relief bypassing.

What size load can I haul on my Rollback?

A 28’ Rollback bed is designed for a 30,000 lb. load evenly distributed. Care must be taken with hard tired equipment as this causes a high point load on the bed between the cross members. Always load in center of the bed over the bed rails for maximum carrying safety.


How do you operate a water truck?

Learn to operate your Ledwell Water Truck correctly to extend the life of your equipment by following the step below or watching this operation video.

Disengage PTO

What should the output of my water truck be?

The pump on a Ledwell water tanker is setup to pump around 400GPM at 2000RPM engine speed with about 55PSI at the spray heads. This should give you a spray pattern of 55′ wide by 30′ deep and a side spray 65′ to 75’out. Most PTOs are in the 111% to 126% range. The pump will peak at 2400-2500RPM (pump speed).

One of the corner spray heads on my 4000 Gallon Water Truck will not shut off. What should I look for?

The air valves on the 4000 Gallon Water Trucks require air to close. If the air supply going to the valve is obtruded or leaking, the valve may not close. There could also be debris stuck holding the valve open.

Why won’t the PTO on my Automatic transmission truck come on when I flip the switch?

On automatic transmission PTOs, the PTO clutch-pack is supplied oil under pressure from the transmission when 12 volts is applied to a solenoid valve mounted at the PTO. On 2000g trucks, this power comes from the switch trough an inline fuse between the switch and the battery. On 4000g trucks with air controls in the cab, the 12v comes from an air contact switch at the battery with an inline fuse also. The air control in the cab closes the contact switch supplying 12v to the PTO. In both cases, the solenoid has a ground wire that must be properly grounded. The contact that turns on the PTO light is a grounding switch that closes when oil pressure is present, turning on the light. If the light is on, the solenoid is working.

My pump turns when my truck is in neutral idling but it stops pumping when I put the transmission in drive, why is that?

On trucks equipped with automatic transmissions such as Allison 2500RDS, the PTO gear drives from the torque converter side of the transmission and it stops when placed in drive at idle. You must add RPM’s to lock the torque converter usually 1000 to 1100 RPM engine speed and the PTO will turn the pump again.

My valves are open, water is flowing, and my pump is turning… Why am I not getting any pressure?

The Berkeley B3ZRM centrifugal pumps used on your water truck are tough and reliable industry standard pumps, but like any pump, they can be broken. Impacting derbies in the intake can jam or brake the impeller. Also, sudden start-ups under load, such as with a manual clutch transmission PTO, can shear the impeller shaft key and retaining nut allowing the impeller to spin free on the shaft. To check for this condition, close the main intake valve, open the cap on the suction intake and visually inspect the impeller. Look for signs of damage or broken retaining bolts.

Can I haul and spray other liquids with my water truck?

Our tanks are lined with Lifelast coating to protect the tank from corrosion. This coating is tolerant of most chemicals with the exception of strong acids, aromatic hydrocarbons, ketones and chlorinated solvents. Always check the content before loading your tank with water mixed products.

My pump will not pump from a water source for self loading…

The most common problem is the foot valve on the end of the suction hose. If this valve is not holding and all the priming water runs out of the pump, the pump will not prime. When priming the pump from the primer tank you must fill the suction hose and pump and bleed the air from the pump with the air valve at the top of the pump before you start up.

The air control console in my 4000g is leaking air around the knobs that control my spray heads…

These slide valve knobs are aluminum in construction with ball detents released by the button on top and over time they can be damaged by dirt and rough handling. Slapping the spools down to close them will cause the ball detents to bend the spools causing a leak. Dirt and contaminates can enter the valve from the top and scratch the spools also if not keep clean.

My pump leaks around the input shaft…

The pump is designed to leak in order to wet the packing and keep it cool. It should leak 40-60 drops a minute and is adjustable with the packing gland ring and the two threaded studs holding it. When all the adjustment is taken up, then it is time to replace the packing.

Why does my pump spray good for a short time then just die down to nearly nothing?

The most common cause is debris in the tank obstructing the pump intake. The pump will pump all the water in the lines then the intake flow slows or stops. There is a screen in the bottom of the tank at the outlet and when filling from a pond or canal, it can become obstructed with debris . Clean this screen and proper pump flow should return.

A standard winch mounted on any Ledwell truck is 5/8″ x 50′ while those mounted on any Ledwell trailer are 5/8″ x 75′.

Wireless Remote

How do you pair a wireless remote to equipment?

Before beginning the procedure, make sure there are no other transmitters in the vicinity being operated, as this can cause issues with the dedication process.

Note that these receivers have the capability of storing two (2) unique ID codes, allowing the use of two (2) different transmitters.

1. Power up the receiver.

2. Locate the green ‘SETUP’ button on the bottom of the receiver as shown in the image to the right.

3. Press the ‘SETUP’ button 5 times quickly. The blue ‘POWER/ACTIVITY’ light will blink 5 times to confirm the correct entry.

4. Press the ‘SETUP’ button once. The ‘POWER/ACTIVITY’ light will blink once.

5. Press any button on the transmitter that will be used with this receiver for at least two (2) seconds. The ‘POWER/ ACTIVITY’ light on the receiver will blink approximately 6 times, indicating that the code has been learned. (Note that on handhelds with system ON/OFF buttons, the ON button must be used in this step).

6. If a second handheld requires dedication, go to step 7. If not, the dedication process is complete.

7. Press the ‘SETUP’ button 5 times quickly. The blue ‘POWER/ACTIVITY’ light will blink 5 times to confirm the correct entry.

8. Press the ‘SETUP’ button twice. The ‘POWER/ ACTIVITY’ light will blink twice.

9. Press any button on the transmitter that will be used with this receiver for at least two (2) seconds. The ‘POWER/ ACTIVITY’ light on the receiver will blink approximately 6 times, indicating that the code has been learned. The dedication process is now complete

Why isn’t the power light activating on my receiver?

Check your 7-way pigtail from the truck to the trailer for power. When the center pin is blue, you have power. If it is not, unplug the 7-way from the back of the truck and check the fixed plug on the truck for power. If there is no power, check for a blown fuse.

When I push buttons on my wireless remote, there are no lights.

There are two possibilities. Either your battery needs charged or you need a new battery. Try charging it. If there is no change, contact Ledwell.

My handheld remote and receiver seem to be pairing, but they are not operating my equipment.

Your air solenoids may be malfunctioning. Each solenoid has a button at its center. Use those to manually operate the air solenoids and ensure their responsiveness.
If there is still no operation, check the twist lock connector for corrosion on the pins.

There is no response when I push buttons on my Base remote, but I’ve just replaced the battery.

When you’re sure the battery is good and the remote has been charged, contact Ledwell. Your hand-held is most likely will need to be replaced.
