Among all the elements that make up the hydraulic system of a Mitsubishi lift truck, its hydraulic pump is the most important one. Surely it is fair to say that this device is the heart of the hydraulic system itself; thanks to it, all hydraulic cylinders of a Mitsubishi forklift can be successfully activated and manipulated. That's why detecting when a Mitsubishi forklift hydraulic pump needs to be replaced on time is crucial. With this in mind, Lift Parts Warehouse wants to share a little more about this vital hydraulic device and the considerations to keep in mind when purchasing a new one.
Do All Mitsubishi Forklifts Have a Hydraulic Pump?
Whether a Mitsubishi forklift is powered by an internal combustion engine or electricity, it must count on a hydraulic pump to perform its operations satisfactorily. These pumps are responsible for developing the pressure energy necessary to start up the set of hydraulic cylinders, which help handle the loads. So the hydraulic pump is one of the most important devices we can find in any Mitsubishi forklift.
They are elements specially manufactured and designed to be reliable and durable; however, like any mechanical device, they will inevitably be affected by wear over the years due to their constant use. When they can't perform well, they must be repaired or changed immediately. If the repair cost exceeds 50% of a new pump, the best we can do is replace it.
The Main Role of a Mitsubishi Forklift Hydraulic Pump
A Mitsubishi forklift hydraulic pump is basically a rotary positive displacement pump that transforms mechanical power into hydraulic energy. A Mitsubishi forklift hydraulic pump is responsible for repeatedly displacing hydraulic fluid by enclosing it in a fixed volume using gears or interlocking gears, transferring it mechanically using a cyclic pumping action. This is how it works:
Due to the hydraulic fluid being incomprehensible, its rapid and constant accumulation within a fixed volume causes its pressure to increase considerably. This increased pressure is what will eventually be used as hydraulic power to activate the set of hydraulic cylinders found on a Mitsubishi forklift, such as the lift cylinder or tilt cylinders.
How Do I Know if My Mitsubishi Forklift Hydraulic Pump is Failing?
It is rare for a Mitsubishi forklift hydraulic pump to break suddenly and unexpectedly. Generally, their failures begin gradually and progressively. If we catch the first signs of failure right away, we will be able to take corrective measures before the defective pump puts the entire hydraulic system of the vehicle at risk. This will not only help prolong the life of the device, but it will also save us a lot of money by avoiding costly repairs. Below we highlight the most common signs or symptoms that indicate when a Mitsubicha forklift hydraulic pump begins to fail.
Metallic Noises. Hydraulic pumps are designed to work quietly, but as parts wear down and seals deteriorate, you may begin to notice unusual noises. Metallic noises are usually a sign of some kind of mechanical issue. This could include grinding sounds, whirring or roaring sounds, rattling, or general noisy operation.
Low Hydraulic Performance. Low hydraulic performance is a symptom of a possible leak. The pump's gears need to be lubricated by the pumped fluid and should not be run dry for prolonged periods. If you see hydraulic fluid coming out of the hydraulic pump, it is possible that its internal seals have failed for some reason.
Failing Seals. If your seals continuously leak and fail, your Mitsubishi forklift pump may operate with a bent or misaligned rod.
High Temperature. High temperatures can occur due to constant friction between the pump's mechanical parts. If they are not properly lubricated, direct contact will quickly wear out the internal gears of the Mitsubifhis forklift hydraulic pump. It may be due to a leak somewhere else in the hydraulic system or a clogged hydraulic filter.
The Hydraulic Pump Turns, but no Flow. If you notice your hydraulic pump motor starting but the truck's pressure needle does not move, it is clear that something is wrong with the hydraulic pump.
What to Do Before Replacing a Mitsubishi Forklift Hydraulic Pump
If the time has come to replace the hydraulic pump on your Mitsubishi forklift, then there are certain considerations you need to take into account before installing the new replacement.
Make sure to clean and bleed the entire hydraulic system. This way, any impurity that may compromise the new pump will be ripped off.
It is recommended, where possible, to replace all hydraulic fluid in the system. This will allow you not only to ensure that the new hydraulic pump has an adequate hydraulic fluid, but it will also allow for better service control.
Replace the hydraulic filter with a new one.
Choosing the Right Hydraulic Pump for Your Mitsubishi Forklift
When you buy a new hydraulic pump for your Mitsubishi forklift, you should consider the following aspects.
Budget. The budget is a crucial factor that we should not overlook. It will decide which hydraulic pump type you can afford. Depending on the Mitsubishi model, its hydraulic pump can be relatively expensive, so you should evaluate all your buying options before making a purchase.
The hydraulic pump type. In the spare parts market, you have to choose between three main categories: OEM, aftermarket, or used. A brand new OEM hydraulic pump would be the best option, but depending on the Mitsubishi forklift model we're talking about, an aftermarket alternative could be easier to get. A used hydraulic pump is not necessarily a bad idea in the short term, apart from being the cheapest option in most cases.
Compatibility. When selecting a new hydraulic pump, the most important thing is verifying its compatibility with the lift truck. Both the hydraulic power and its dimensions are factors that should not be overlooked.
The distributor. Finally, the distributor is the last aspect to take into account. You should always buy your new hydraulic pump from an establishment with a good and reliable reputation that can offer at least a purchasing guarantee for the product.
