priming tractor hydraulic pump made in china

I am only able to access the output line down at the manifold under the floor plate (next to the dead man) in order to get to the output of the pump, I will need to remove the steer motor and/or lift the pump and motor. I am however able to get the output line at the manifold and crack that line but nothing happens, just some drips. I am unsure what the "suction" line is, I am assuming its the "feed line" (thats probably bad terminology but thats what I would call it). I can access it by moving the battery a bit, but this line connects directly to the bottom of the tank (which is full of fluid), its about a 1.5" hose, and I am afraid if I remove it from the pump all the oil will come out of the tank. I am also thinking this line should be full already because its below the tanks oil level.

Technical Editor Tom Dickson checks out a 45hp East Wind DFS454 tractor to see if this made-in-China-for-Australia machine is up to the tasks it’s designed for

The brand was created by Queensland-based Midway Sales to produce low-cost premium tractors for the Australian market, with the machines being manufactured in the Dongfeng factory in China.

The crew at Midway Sales say they have worked closely with Dongfeng over the last 10 years to produce a tractor that will suit Aussie conditions. They have their own employees in the factory in China to ensure quality control is maintained and to guarantee the tractors are built strictly to East Wind specifications.

The tractors in the range fit into the small-horsepower bracket aimed at hobby farmers, lifestyle farmers, or those who just want to get out on the weekend and clean up around the block without having to fork out a pocket full of money.

The ties between East Wind tractors and the machines Dongfeng sells under its own brand are strong. For instance, our review tractor, the East Wind DFS454, is a 45hp four-wheel drive tractor with 8-speed transmission, synchro shuttle and ROPS, and is virtually identical to the Dongfeng ZB45.

In addition, Midway Sales says the East Wind tractors are specifically suited to Australian conditions. The company’s confidence is supported by the four-year warranty that it offers.

Coincidently, he has a 4WD East Wind DF345 tractor in mint condition parked in his shed. It is one of the first models to go on sale and was purchased about 10 years ago by Hughes to carry out general hobby farming duties like driveway maintenance, drainage work, carting firewood, and cleaning up fallen trees.

I admit to having been sceptical about the performance and reliability of some of the Chinese-made tractors in the past, but listening to Hughes praise the performance of his machine goes a long way towards increasing my confidence. When you factor in the $22,990 purchase price, you would be foolish not to at least have a look.

The exhaust pipe comes out low down at the bottom of the engine near the front wheel, which reduces the noise level considerably but, more importantly, prevents exhaust fumes blowing directly into the face of the operator on the cabinless tractor.

The fuel tank holds a total of 28 litres and has its filling point through the top of the bonnet, just in front of the steering wheel. It’s at a comfortable height to easily fill while you’re standing on the ground beside the tractor.

At around 2000rpm it produces ample power to propel the 2.6-tonne tractor and loader combination up the hills on Hughes’ property and run a 1.5m slasher at the same time.

The engine oil and oil filter must be changed every 100 hours, and it is recommended that the fuel filter element, injector pump oil, front diff and final drive oil, power steering oil, radiator coolant and the air cleaner element be replaced at the same time. The transmission oil and hydraulic oil filter changes are set at 200-hour intervals to coincide with every second engine service.

The four-wheel drive engaging lever is also mounted on the left-hand side, while the right side is home to the throttle, linkage control, diff lock, high/low range lever, handbrake, and a couple of lightweight-looking hydraulic levers.

The hydraulic system consists of a main pump delivering a total of 33.6L/min to two sets of hydraulic remotes at the rear. I find it quite puzzling to discover that, instead of having all female ends on the couplers like most tractors do, each set of remotes has one female end and one male end. Most implements that I have seen use male ends, so you would have to change the couplers to match the tractor.

The self-levelling front-end loader comes standard with a four-in-one bucket, joystick controller and an integrated third function button. It has a mechanical bucket level indicator to aid its operation. Safety locking pins are included with the loader to lock it in the up position when you’re working in and around the front of the tractor.

The seat position certainly isn’t a huge issue but if it were my tractor I’d drill a few extra holes and move the whole seat mounting assembly a little bit forward.

The roll-over protection, ROPS, bar is hinged about half-way up, so it may be temporarily lowered. With the bar lowered, the tractor can get under obstacles and reach areas that are otherwise inaccessible.

With a front-end loader for heavy lifting, four-wheel drive to get you through the mud, a roof for weather protection, and lights for night work, there is not much else you could wish for. Add to it a slasher, linkage grader blade, hydraulic log splitter and maybe some lightweight cultivation equipment, and you’ve just about got the job covered.

If you’re in the market for a no-frills tractor that doesn’t include heating, cooling or the latest sound system, the DFS454 could be the one because it seems to tick all the other boxes.

It even has a battery isolation switch to avoid a power drain, which often occurs with hobby and lifestyle farming tractors because they spend a lot of time parked in the shed.

So I"ve got a brand new hydraulic pump coming for my Takeuchi TB145...(for anyone who remembers my other thread, I ended up ordering it from a local vendor here in the US instead of ordering it from overseas...more money but peace of mind)

Any tips for installing? My basic understanding is to bolt it to the engine, connect all the hydraulic lines, fill the hydraulic tank with fluid and crack the bleed valve on the pump until solid fluid is flowing out...then let her rip. That pretty much it in a nutshell?

Any tips/info at all would be appreciated. The pump should be here either the end of this week or early next week, so I"ll probably be ready to do this mid-week next week.

A hydraulic pump converts mechanical energy into fluid power. It"s used in hydraulic systems to perform work, such as lifting heavy loads in excavators or jacks to being used in hydraulic splitters. This article focuses on how hydraulic pumps operate, different types of hydraulic pumps, and their applications.

A hydraulic pump operates on positive displacement, where a confined fluid is subjected to pressure using a reciprocating or rotary action. The pump"s driving force is supplied by a prime mover, such as an electric motor, internal combustion engine, human labor (Figure 1), or compressed air (Figure 2), which drives the impeller, gear (Figure 3), or vane to create a flow of fluid within the pump"s housing.

A hydraulic pump’s mechanical action creates a vacuum at the pump’s inlet, which allows atmospheric pressure to force fluid into the pump. The drawn in fluid creates a vacuum at the inlet chamber, which allows the fluid to then be forced towards the outlet at a high pressure.

Vane pump:Vanes are pushed outwards by centrifugal force and pushed back into the rotor as they move past the pump inlet and outlet, generating fluid flow and pressure.

Piston pump:A piston is moved back and forth within a cylinder, creating chambers of varying size that draw in and compress fluid, generating fluid flow and pressure.

A hydraulic pump"s performance is determined by the size and shape of the pump"s internal chambers, the speed at which the pump operates, and the power supplied to the pump. Hydraulic pumps use an incompressible fluid, usually petroleum oil or a food-safe alternative, as the working fluid. The fluid must have lubrication properties and be able to operate at high temperatures. The type of fluid used may depend on safety requirements, such as fire resistance or food preparation.

Air hydraulic pump:These pumps have a compact design and do not require an external power source. However, a reliable source of compressed air is necessary and is limited by the supply pressure of compressed air.

Electric hydraulic pump:They have a reliable and efficient power source and can be easily integrated into existing systems. However, these pumps require a constant power source, may be affected by power outages, and require additional electrical safety measures. Also, they have a higher upfront cost than other pump types.

Gas-powered hydraulic pump:Gas-powered pumps are portable hydraulic pumps which are easy to use in outdoor and remote environments. However, they are limited by fuel supply, have higher emissions compared to other hydraulic pumps, and the fuel systems require regular maintenance.

Manual hydraulic pump:They are easy to transport and do not require a power source. However, they are limited by the operator’s physical ability, have a lower flow rate than other hydraulic pump types, and may require extra time to complete tasks.

Hydraulic hand pump:Hydraulic hand pumps are suitable for small-scale, and low-pressure applications and typically cost less than hydraulic foot pumps.

Hydraulic foot pump:Hydraulic foot pumps are suitable for heavy-duty and high-pressure applications and require less effort than hydraulic hand pumps.

Hydraulic pumps can be single-acting or double-acting. Single-acting pumps have a single port that hydraulic fluid enters to extend the pump’s cylinder. Double-acting pumps have two ports, one for extending the cylinder and one for retracting the cylinder.

Single-acting:With single-acting hydraulic pumps, the cylinder extends when hydraulic fluid enters it. The cylinder will retract with a spring, with gravity, or from the load.

Double-acting:With double-acting hydraulic pumps, the cylinder retracts when hydraulic fluid enters the top port. The cylinder goes back to its starting position.

Single-acting:Single-acting hydraulic pumps are suitable for simple applications that only need linear movement in one direction. For example, such as lifting an object or pressing a load.

Double-acting:Double-acting hydraulic pumps are for applications that need precise linear movement in two directions, such as elevators and forklifts.

Pressure:Hydraulic gear pumps and hydraulic vane pumps are suitable for low-pressure applications, and hydraulic piston pumps are suitable for high-pressure applications.

Cost:Gear pumps are the least expensive to purchase and maintain, whereas piston pumps are the most expensive. Vane pumps land somewhere between the other two in cost.

Efficiency:Gear pumps are the least efficient. They typically have 80% efficiency, meaning 10 mechanical horsepower turns into 8 hydraulic horsepower. Vane pumps are more efficient than gear pumps, and piston pumps are the most efficient with up to 95% efficiency.

Automotive industry:In the automotive industry, hydraulic pumps are combined with jacks and engine hoists for lifting vehicles, platforms, heavy loads, and pulling engines.

Process and manufacturing:Heavy-duty hydraulic pumps are used for driving and tapping applications, turning heavy valves, tightening, and expanding applications.

Despite the different pump mechanism types in hydraulic pumps, they are categorized based on size (pressure output) and driving force (manual, air, electric, and fuel-powered). There are several parameters to consider while selecting the right hydraulic pump for an application. The most important parameters are described below:

Speed of operation: If it is a manual hydraulic pump, should it be a single-speed or double-speed? How much volume of fluid per handle stroke? When using a powered hydraulic pump, how much volume per minute? Air, gas, and electric-powered hydraulic pumps are useful for high-volume flows.

Portability: Manual hand hydraulic pumps are usually portable but with lower output, while fuel power has high-output pressure but stationary for remote operations in places without electricity. Electric hydraulic pumps can be both mobile and stationary, as well as air hydraulic pumps. Air hydraulic pumps require compressed air at the operation site.

Operating temperature: The application operating temperature can affect the size of the oil reservoir needed, the type of fluid, and the materials used for the pump components. The oil is the operating fluid but also serves as a cooling liquid in heavy-duty hydraulic pumps.

Operating noise: Consider if the environment has a noise requirement. A hydraulic pump with a fuel engine will generate a higher noise than an electric hydraulic pump of the same size.

Spark-free: Should the hydraulic pump be spark-free due to a possible explosive environment? Remember, most operating fluids are derivatives of petroleum oil, but there are spark-free options.

A hydraulic pump transforms mechanical energy into fluid energy. A relatively low amount of input power can turn into a large amount of output power for lifting heavy loads.

A hydraulic pump works by using mechanical energy to pressurize fluid in a closed system. This pressurized fluid is then used to drive machinery such as excavators, presses, and lifts.

A hydraulic ram pump leverages the energy of falling water to move water to a higher height without the usage of external power. It is made up of a valve, a pressure chamber, and inlet and exit pipes.

A water pump moves water from one area to another, whereas a hydraulic pump"s purpose is to overcome a pressure that is dependent on a load, like a heavy car.

We have a 1256 that was doing the same thing a couple years ago. That is what brought me to this forum as well. We fought it for quite a while before we finally broke down and had the mcv rebuilt and a new steering pump installed. The mechanic said that the spring in the valve was broken, I assume it was the pressure relief valve that dale560 mentioned. After doing that we have had no problems at all with it losing prime.

The things we tried that didn"t work- Over filling by 5 gallons, this seemed to help but didn"t cure the problem. Parking uphill, this also helped some of the time but didn"t fix anything. Blowing air into the fill tube, this I couldn"t make work at all. If you are having trouble with it losing prime you have a problem with the mcv. These tractors should work fine with the oil on the add mark, no matter how long it is parked or at what angle it is parked. That is how our 1256 is now.

Since then I have also replaced the main hitch pump with a 17 gpm unit from IH, (CNH), and put in a 2500 psi relief valve. That really made a difference in the hydraulics. When it got cold out this winter, I also had trouble with the hydraulics not working untill the tractor had warmed up for a while. Once it warmed up, they worked fine. So I ordered the hydraulic oil filter extension that lets you run two filters. I installed it yesterday and it cured the problem. The pressure was right there this morning at start-up at 10F. It is still stiff because at that temp the oil flows like maple syrup, but you can still steer it and drive it right after starting. The hydraulics also move much faster, with the double filter and the larger pump it really makes the loader fly.

My recomendation for those losing prime would be to get the mcv rebuilt and have the steering pump replaced. That should fix the problem. Just break down and do it.

For those having trouble with their hydraulics in the cold, I would get the double filter kit. After my experience the last couple days, I am very happy I did.
