pj dump trailer hydraulic pump troubleshooting quotation

The only complaint I have was with the packaging for shipment. One of the main bolts was missing. It appears that the mounting bolts and washers are installed then hand tightened. In my box, the bolt was missing but the 2 washers and nut were there. Another nut and washer had come off of a second bolt. The box was in pretty bad shape when it arrived, and I"m sure that missing bolt escaped that way. I blame UPS, not PJ. But nonetheless, I was missing a bolt. It might be a better practice for future shipments to place all hardware in a sealed bag and attach that bag to the bracket. Preferably with some shrink or Saran type wrap. But that"s just my suggestion.

I have just written about solutions for one of the biggest Dump Trailers problem – hydraulic pump troubleshooting. If you don’t have time for long reading and wanna look for corresponding solution about dump trailer hydraulic pump troubleshooting, here you will find everything in detail – why do pumps fail, repair guide and tips from experts; among many other things.

Is the pump supplying sufficient pressure?Test pressure to verify pump is supplying correct pressures (“C1” port 3200psi) (“C2” port if double acting unit – 500 psi). Pressure should be within +/- 100 psi.

Is the motor turning the correct RPM?Step 1: Locate the main wiring harness for your dump trailer motor. This will be a bundle of wires that are connected to each other at one end and run from one side of your vehicle to another. The main wiring harness will likely have several different colors on it, including red, white and black.

Step 4: Plug one end of your tachometer into this plug and connect the other end to an electrical outlet in your home or garage that has power running through it (for example, if you’re working outside during daylight hours, plugging it into a light socket will work).dump trailer hydraulic pump will not lift load

Is the pump grounded to the battery, or to the frame of the truck? It should be grounded directly to the battery.Is the pump getting enough volts or amps to activate the solenoid switch?

Is the hoist closing faster than the power unit can pump oil back into the top side of cylinder?Is the hoist closing faster than the power unit can pump oil back into the top side of cylinder?

Check to see if water has gotten in hydraulic fluid and is freezingIf you’re having problems with your hydraulic system freezing, start by checking for leaks. There are two places where you might find a leak: around the steering wheel and in the lines leading up to the steering column.

Screen on suction tube in reservoir could be getting dirty. How long has it been since hydraulic fluid was changed?If you have not changed the hydraulic fluid in some time, then it is time to do so. If you have not checked the level of fluid recently, then I would suggest doing that as well. It is also a good idea to check for any damage in the hose or fittings that might cause a leak.

Installing a pressure gauge on a hydraulic pump is a great way to monitor the operation of your trailer. It will allow you to see how much pressure is in your system, and will also tell you if there are any leaks. In this article, we’ll show you how to install a pressure gauge on a 12 volt hydraulic pump for your dump trailer.

The first thing you need to do is remove the cap from the back of the pump. You can do this by turning it counterclockwise with your fingers or by using an adjustable wrench. Once it’s off, you should see what looks like a large bolt sticking out of the bottom of the pump. This is the check valve. It’s used to prevent fluid from escaping when no pressure is applied to it. We’ll be removing this part later on so that we can attach our new gauge.

The hydraulic pump is the heart of the hydraulic system, and the size of your hydraulic pump will have a direct effect on how much work can be done with it. The larger the pump, the more pressure it can create.

Faulty wiring.This is a common problem when you have a trailer that’s equipped with an electric hydraulic pump. If there is a short circuit or ground fault in the wiring, then it can cause your hydraulic pump to fail.

Loose connections. Another common problem is loose connections on the wires running from your dump trailer hydraulic pump to your controller box. This can be due to corrosion, worn out terminals, or just improper installation of new parts.

Bad controller box. If you have a controller box failure, then it could be causing your dump trailer hydraulic pump not to work properly. You may need someone who specializes in dump trailer repair to check out your controller box if this happens to you.

A hydraulic pump is a device that converts the energy of a fluid into mechanical energy by means of the pressure, velocity or flow rate of the fluid. In this article, we will focus on how to purge a dump trailer hydraulic pump.

1.Find the drain plug at the bottom of your dump trailer hydraulic system. If you don’t see one, look in your service manual for instructions on how to find it.

3.Remove all oil from inside of your dump trailer’s hydraulic system using either compressed air or an oil-free solvent like kerosene or mineral spirits (not gasoline). Spray down all parts with compressed air or hand wipe them off until they’re clean of any oil residue and dry before continuing with steps 4 through 8 below.

Causes include a failed solenoid, poor electrical connections between the control and the pump, or loose wiring in the remote itself. If the pump is running but doesn’t affect the hydraulics, it may be a stuck valve. If when the pump works in one direction but not the other, try swapping the coils, to see if it will work in the opposite direction. If this is the case, you will have a faulty coil.

The dump trailer hydraulic pump is connected to the trailer hitch and is controlled by a dash mounted switch. The switch activates the relay, which in turn energizes the pump motor. When you press the brake pedal, it activates the relay and powers the circuit to open the dump valve. The cable from the brake pedal runs through a mechanical linkage that opens the dump valve when you press on it.

The dump trailer hydraulic pump is powered by a 12 volt battery, which is connected in series with a fuse and relay. The battery provides power to operate all of your vehicle’s electrical systems, including lights and accessories as well as starting your vehicle’s engine through an alternator or starter motor.

If you want to fix the hydraulic pump on your dump trailer all by yourself, you can use the tips in this article for help. You can save time and money by not having to call an expensive mechanic out to fix a simple problem that you have already fixed yourself.

I know a few guys are using dump trailers. I have a Load Trail 6x10. It has the standard 12v hydraulic double acting power pack that’s found in many trailers.

It’s going on 10 years old. When I bought it, I ended up changing the battery as it seemed to not hold a charge and drained very fast. I also changed the brake ‘break away’ module (ended up not leaving it hooked up to eliminate a source of power drain), I removed the restrictor from the base end of the cylinder to reduce any fluid restrictions (hope the line don’t break with the box up!)changed the hydraulic oil (to Kubota SUDT as that’s what’s in my tractor and I now have it rigged to use the tractor remotes or the 12v so the oil has to match).

Ive since gone through a few more batteries. If I’m lucky I get 2 or 3 dumps on a group 24 deep cycle. I ended up not using the standard truck charge wire from the 7 pin plug, as it would blow the trucks fuse for the towing. ( when it was dumping)

So I put in 4ga wires from the truck battery back to the trailers battery, connected through a solenoid and self resetting 50A CB. When dumping that CB cycles off and on as the draw is well over 50 amps.

However, none of this explains why a new battery will only get a few dumps. I’ve tried using a carbon pile load meter to check for amp draw and figure with comparable voltage drops (tester vs dumping) that the pump is drawing 200-250 amps. There is no rating on the stamp on the motor/pump.

Perhaps the motor is getting tired and the brushes are wore? I disassembled the hydraulic unit yesterday and cleaned everything I could and found nothing obvious. I did not take the electric motor apart. The pump feels ‘ok’, the solenoid valves all seem to click and move so oil should be flowing the right way. (The relief valve is rusty looking so I left that alone for fear of damaging it but that’s just external rust/looks and even if it was not functional it shouldn’t cause grief like this)

The industry standard frame warranty for most equipment trailers is one (1) year. We believe so strongly in our frame strength that we offer a three (3) year frame warranty on all PJ equipment trailers and car haulers.

Some manufacturers cut corners by using lighter gauge materials for the sides and floors. Lighter floors and sides leads to warping and the deformation of the bed. It is especially important to use heavy gauge floor materials for loading equipment into dump trailers due to the higher weight concentrations between cross-members. At PJ Trailers we use 10 gauge smooth plate (.1345" thickness) on all dump beds and fixed (non fold-down) sides.

Most of our dump trailers feature a two way barn door and spreader gate standard. The spreader allows you to dump your material evenly when the bed is raised. This is great for sand, gravel, and other even flowing loads. The barn door function makes it easy to load equipment with no interference by pinning the doors to the side of the trailer. The barn doors are also great for dumping bulky loads like firewood, scrap metal, and brush that could get jammed when using the a spreader gate.

All 14,000+ lbs PJ dump trailers include a scissor hoist as a standard feature. A scissor hoist is much stronger and has more lifting power than single or twin hydraulic cylinders. The scissor design also is much more stable for raising and lowering uneven or shifting loads.

One of the greatest features of dump trailers that is often overlooked is their ability to haul equipment (skid steers, mini-excavators, tractors, etc). All PJ Trailers 7" wide dumps or larger include ramps as a standard features. Ramps add versatility to the use of the trailer and to its value.

We keep our cross-members spaced very tightly together (typically 16" or less). This combined with our heavy duty 10 gauge flooring makes for an extremely strong dump bed that will be able to handle years of heavy use without failing. Many manufacturers space their cross-members too far apart to try to cut costs.

Trailer wiring issues are one of the top complaints for many dump trailer owners. This is why we use a sealed wiring harness to protect our wiring from water, dirt, and corrosion. The harness is enclosed in steel conduit throughout the frame of the trailer, to further protect the wiring from ice, road debris, and physical damage. This modular harness means each light is just simply plugged in, making replacement very easy.

Every PJ dump trailer features Lifetime LED lights standard. LED lights are brighter, faster, draw less current, and last longer than incandescent lights. The lights are so reliable they feature a lifetime warranty.

At PJ Trailers we think our best "advertising" comes from jobsites and coffee shops, not on billboards and television ads. We didn"t "buy" our reputation for building great trailers, we built it — one trailer at a time. Building a great product and keeping our customers happy has made us the #1 professional grade open trailer manufacturer in the US.

Radial tires are superior to bias ply tires in many ways. Radial tires feature better fuel economy, less vibration, a softer ride, and extended life due to less heat being generated by the tire. Radial tires are especially important for dump trailers due to some of the heavy loads they must handle.

Both bumper pull and gooseneck PJ dump trailers receive a Bulldog™ coupler as a standard feature. These couplers are height adjustable to allow you to level the trailer with the towing vehicle. The Bulldog™ coupler has a well-earned reputation for being the toughest, most durable coupler in the trailer industry.

If you want a dump trailer that lasts, it has to be built on a solid foundation. Some manufacturers attempt to cut cost by skimping on frame materials (smaller channel & beam, fewer welds, less cross-members). Our dump trailers take frame strength to the next level and we have the warranty to prove it.

Every PJ dump trailer includes an integrated trickle battery charger. The charger is included inside the toolbox and is pre-wired to the battery. To charge your trailer plug in your 110v extension cord to the outlet on the exterior of the toolbox, that"s it!

We are obsessed with making sure our dump trailers provide years of reliable service. We add grease zerks to just about everything that can move and needs grease. This includes the rear doors, fold-down sides, scissor hoist, toolbox lid, and even ramp pocket doors. While other manufacturers" moving parts will be seized or rusted, ours stay smooth and ready for years of work.

Plan on using your dump trailer to haul equipment like skidsteers, mini-excavators, tractors, and mowers? We have two models (DL & DJ) that feature a 24" deck height making it extremely easy to load equipment into the bed. Most other manufacturers only build traditional height dump trailers that have the higher 32"-36" deck heights.

We mount d-rings in the dump bed which are great for securing equipment. Even if you don"t use your dump trailer to haul equipment, they are great for strapping pallets and other bulky cargo.

Need to haul bulky items that extend beyond the typical height of our sides? Every fixed side dump trailer we build has solid side extensions that can be added on. We also have expanded metal and 10 gauge heavy duty side extensions for many of these models.

Dump trailers require special reinforcements throughout the entire trailer due to the massive amounts hydraulic power required to raise and lower the dump bed. We reinforce the high stress areas with techniques including double frames, gussets, and support plates. These reinforcements ensure years of reliable use.

We offer tarp brackets as a no charge option. This makes it very easy to add a tarp kit to your PJ dump trailer at any point in time. We also include tarp hooks around the perimeter of the trailer at no additional charge.

Every PJ dump trailer is equipped with an Interstate deep cycle battery. Deep cycle batteries are designed to be deeply discharged repeatedly, unlike an automotive battery. We use Interstate due to their stellar reputation for building top quality batteries and providing reliable service.

We always mount our hydraulic pumps and batteries inside of a locking toolbox. This protects the hydraulic system from damage while also securing these high value components from theft. We also feature a gas assist shock that lifts and keeps the lid in the open position. Our gooseneck dump trailers feature a chain tray between the risers in addition to the locking toolbox.

All of our dump trailer lights are "flush-mounted" inside the frame of the dump. Surface mounted lights are much more susceptible to damage, corrosion, and failure.

When shopping for a dump trailer one thing to consider is the size and quality of the dealer network that provides support for the manufacturer. Our network of over 250 dealers is well respected for offering excellent service and support.

We reinforce our dump bed sides with heavy duty 10 gauge formed supports on the outside of the bed. This helps prevent the sides from becoming damaged and deformed over years of hard use.

We don"t believe a customer should have to settle for a dump trailer that isn"t exactly what they want. That is why we offer a wide variety of options for our dumps including sides extensions, spare tire mounts, solar chargers, hydraulic jacks, cold weather wiring harness, and more. We literally have thousands of option combinations to make sure your trailer is suited for your type of work.

We use 10 gauge wiring for our trailer brakes to make sure the brakes receive full power to stop the trailer. The best brake controller and electric brakes can quickly become inferior if the wire is too small to transmit full power to the brakes. This wiring is slightly more expensive than what others use but it is well worth it.

If there is an axle, brake, or suspension combination you would like on a dump trailer, we probably have it. We work very closely with our vendors to provide a wide variety of axles and suspensions. These include hydraulic disc, hydraulic drum, surge brakes, drop axles, torsion suspension, 8k, Hutch suspension, air ride, air brakes, and more.

The majority of our dump trailers use a single piece side and floor with a seam that runs down the center of the trailer. This makes for just single weld that runs in the same direction that material dumps out of the trailer. This keeps your material flowing smoothly without hanging up on welded floor plates that run opposite to the direction of flow.

Our sides on the 84" DN and 96" D8 dumps fold down to allow for easy side loading of pallets and other cargo. To lower the sides, simply pull the two spring loaded pins and slowly lower the side. We even have added grease zerks to the hinges for years of smooth, hassle-free operation.

Great materials, components, and build quality are irrelevant if the trailer is poorly designed. When you have built tens of thousands of dump trailers you receive ample feedback about your product (both good and bad). We have used this valuable information to refine our product, making both major innovations and minor improvements over the years. We continue to develop new ideas and solutions to keep our dump trailers at the top of industry.

Having a great looking trailer adds professionalism to your business and gives your customer extra confidence. Our customers often make a large investment in their truck and expect their trailer to compliment the vehicle towing it. We believe you should be proud of your trailer, not embarrassed!

Our dump trailers are equipped with a self-contained hydraulic unit manufactured by KTI Hydraulics (Costa Mesa, CA). Our pumps are specifically designed for trailer use and only need the deep cycle battery (contained in the toolbox) to operate.

Our dump trailers are built in compliance with the National Association of Trailer Manufacturers trailer safety regulations. Be very wary of any manufacturer that does not comply with NATM safety standards

All PJ dump trailers include a Bargman 7-way plug. These plugs are designed with dual contacts for a more reliable connection. They also include an auxiliary wire that can be used to operate work lights, reverse lights, & charging. View our optional Cold Weather Plugs.

When you order a PJ Gooseneck Dump it comes with an 8" - 12" I-beam neck standard. Our I-beam necks are simply stronger and last longer than the commonly used 6"-8" c-channel necks. At PJ Trailers we feel that an I-beam gooseneck should be standard, not an "upgrade".

Our dump trailers feature West Craft hydraulic cylinders. West Craft Manufacturing, Inc. is a manufacturer based in Alto, Texas that builds top quality and reliable cylinders.

If you have ever shopped for a used PJ dump trailer you might be surprised how close the price can be to a new trailer. Our premium components and overall build quality makes for a trailer that ages well and will retain much of its original value.

One place other manufacturers try to save a few bucks is by using cheap hydraulic hoses and hardware. At PJ Trailers we use high quality Parker hoses and fittings on every dump trailer we build. This ensure years of safe and reliable operation.

Our dump trailers are pre-wired through the 7-way plug to maintain the battery when connected to the towing vehicle. To completely recharge the battery, you will need to use the integrated battery charger.

Our barn door/spreader tail gates can be easily removed by pulling two pins at the top of the gate and unlatching the bottom of the gate. This allows you to haul cargo or equipment that would extend past the bed of the dump trailer.

Our fixed side (non fold-down) dump trailers include stake pockets standard. This allows you to easily add or even build side extensions for almost every model. They can also be used to secure loads and add aftermarket accessories.
