The Komatsu PC35MR-2 mini excavator has a built in hydraulic pump that is used to drive the machine. It is a compact unit that runs off of the engine and does not require any other power. The hydraulic pump is made up of many different parts and will need to be replaced if any of them fail.

The first step in disassembly is removing the hydraulic tank cap which holds all of the internal components together! This part can be found on top or bottom depending on your model number (see picture below). After removing this cap you will see three screws holding down another plate which contains your hydraulic pump’s valves and other components.

Once these two pieces have been removed, use an Allen wrench to unscrew all three bolts from their respective locations (one in each hole). These bolts are located right under where the oil dipstick was once mounted so they should be easy to find! The next thing you’ll want to do before removing anything else from inside this compartment is take note of where everything connects so when you go back for reassembly there will no confusion about what goes where!

the fault point is identified, and the symptoms that appear at the fault point are recorded in detail

Komatsu pc35-mr2 Excavators are a necessary construction machinery and are widely used, but if the performance of excavators is not good, it will affect the completion of the project, so everyone must know how to maintain the excavator. The excavator fault point is identified, and the symptoms that appear at this point are recorded in detail. In actual operation, it is found that there is a problem with the fault point. After some analysis, you can find out what is going on and then deal with it immediately. You can’t wait until it’s too late to go wrong before you can fix it, otherwise your project will be delayed.

1. Check whether each valve core of the main oil circuit of the hydraulic system and each oil circuit of the auxiliary oil circuit are reliable. For example, if there is a crack in the pump body or a crack in the valve core seat, oil leakage will occur;

2. If there is an oil leakage in parts such as hydraulic cylinder and hydraulic motor shaft seal ring, it may be due to aging or damage of sealing parts;

3. If there is oil leakage in other parts of hydraulic oil circuit, we should check whether hydraulic pipe connection joint leaks or hydraulic pipe joint leaks due to improper tightening torque;

Hydraulic pump assembly, overhaul or replacement of defective parts, and re-disassembly, re-assembly and adjustment

1. All the hydraulic pump parts should be cleaned before assembly and checked for damage.

2. Before installing the front bearing, check it with the shaft. If it is found to be loose, replace it with a new one.

3. When installing a new plunger, check the fit between the plunger and the piston hole of the cylinder block; otherwise, replace it with a new one.

4. The fit of the oil pump seal ring should meet the requirements; otherwise, it should be replaced with a new one.

5. When assembling and disassembling the oil pump valve plate, pay attention to matching with the bottom plate to prevent errors from causing poor sealing performance or failure to work normally after assembly.

6. When replacing bearings, replace them all at once to ensure reliable operation of bearings and avoid uneven load distribution caused by different degrees of wear on various components in different positions.

The action of each cylinder is checked again, and a load test is performed to determine whether the problem is solved

Komatsu pc35-mr2The action of each cylinder is checked again, and a load test is performed to determine whether the problem is solved. If the problem is not solved, further repair work must be performed. The most common reasons for incomplete repair include the following:

1) Repair of the mesh gap in the mesh gear assembly: Incomplete repair may be caused by the following factors:

A) There are still cracks in the mesh gear body that have not been repaired or repaired.

B) The original position of the mesh gear body has changed due to deformation, so it is difficult to achieve a good contact effect with the worm gear after installing the mesh gear.

C) After installation and adjustment, due to poor contact between the gears and/or poor lubrication, wear will generate heat and cause thermal expansion, which will cause the gap between gears to increase.

2) Repair of bearing seat (split sleeve): Incomplete repair may be caused by the following factors:

A) The clearance between bearing cage and main shaft is too large.

B) The bearing cage or main shaft has a taper fit or an interference fit with the split sleeve or bearing housing, which makes it difficult to maintain a certain preload when adjusting.

The excavator pump is pressure and flow proportional control, the oil pressure is lower than the set value, the flow of fuel will be reduced, will not cause excessive fuel consumption, to avoid an accident.

The new hydraulic system has been further improved and has a high efficiency. The excavator’s boom, arm and bucket movement are smooth; the oil cylinder end movable mechanism is increased to increase the stability of the machine; The main valve adopts the pilot type precision throttle regulating valve to improve the response sensitivity of the excavator, so that it can achieve accurate positioning accuracy in a short time.

Prepare the tools needed for the operation in advance, and then clean the parts around the machine to prevent dust from falling into the construction machinery.

The work of Komatsu excavators is mainly for digging, so it is necessary to ensure that the bucket cylinder is in good working condition. The bucket cylinder is an important component of excavator, which has important influence on the normal operation of excavator.

If there is a fault in the bucket cylinder of Komatsu pc35-mr2 excavator, it will lead to its failure under certain circumstances. For example, when it is operated at high speed or under heavy load, it may be unable to operate normally due to insufficient pressure inside the cylinder or insufficient lubrication between piston rod and inner wall of cylinder tube, resulting in reduced lifting force or even failure.

So how should we do Komatsu pc35-mr2 bucket cylinder fault maintenance? Here are some steps:

1. Put down the shovel arm and open the valve cover of the bucket hydraulic pump on the side;

2. Pressurize with compressed air and check whether there is any leakage from hydraulic oil pipe connection;

3. Check whether there is any leakage from hydraulic
