Vulnerability of loaders and solutions:
Load engine is working. Loader cannot walk
The transformer tank's oil limit valve and rate pressure table are first checked. New oil should be added if a lack of speed rect oil is found. However, it is not appropriate to add more, otherwise it would cause the heat to heat the gear transformer, usually until the limit valve is released. It is then checked if the moving arm can rise and turn, and if the moving arm can turn, the loader is unable to walk because of the lack of oil for the damage to the speed pump. The mobility arm is unable to rise and turn, and the loader cannot walk, mostly as a result of the bolting of the steel plate connection of the rectangular, or the bursting of the elastic plate. The diesel engine and the gearbox must be suspended and the link of the diesel machine loaded with the machine rectangular removed, the damage was identified and the damaged parts replaced or repaired.

2. The speed pressure of the loader, the movement arm, the turner and the turner are all normal, but the loader is still unable to move forward and retreat to check first for lack of fuel in the gear tank and congestion in the pipeline, and then for oil casings and rectangles filters of the loader. If metal fragments, etc., are found, it is certain that there is damage to the parts in the loader's transmission box that are large and large. If aluminium crumbs are found in transformer tank oil casings and rectangular filters, the damage to the parts inside the rectangular is certain. At this point, the gearbox and the rectangular must be removed, and the damaged parts must be repaired and replaced. To exclude the above reasons, the vehicle is still unable to walk, and it can be determined that the bolt around the second block in the gearbox has been severed or that the mid-axis output gear has been removed so that power cannot be exported. Method of exclusion: the 8-word end cap of the gearbox can be removed, the second block removed, and the bolts cut can be replaced. This bolt material is 40cr and must be trimmed and never replaced by an ordinary bolt. Lehman's heavy work
3. The loader pressure is normal and cannot walk either side or side, and most of the reasons for the failure are that the second side is able to travel normally because of a direct change of block without stepping on the pedal to break a reverse block link in the gearbox and prevent the power transmission. And the second side is directly connected to the inside of the wheel, so the second side can drive。
4. Load engine is weak and stops while moving
(1) check the oil limit valves next to the transformer and fill them with new oil if they are lacking。
(2) if the quantity of oil is normal, the rate pressure table shall be checked. If the pressure table is swinging sharply, indicating a lack of fuel supply, it is possible to check, in turn, whether the pipeline is blocked, whether the inner layer of the tube is bubbled by ageing, whether the rectangular filter is clean and whether the filter core is clean. In the case of these reasons, the catheters and filter cores that are clogged and washed repeatedly with compressed air are washed and used until they are fully accessible. The foaming tubes are replaced. Lehman's heavy work
(3) observe the presence of, for example, metal blocks and aluminium crumbs on the filter network and, for example, indicate the presence of damaged parts in the rectangulars and in the gearbox, the parts must be decomposed and replaced。
Five, the loader can only move forward, not back
First, check whether the pressure indicated by the speed pressure table is normal. If the rewinding pressure is reduced, it proves that the rewinding is too much oil, and the gearbox must be removed and all removed for inspection. Take out the piston, replace the piston ring, check for damage to the friction tablet, replace the more worn friction tablets, and reset the gap between the reverse block to 1. 6-2. 6 mm; if you do not break the pressure, prove that there is a blockage. If the reverse friction sheet is slipped so that the reverse block cannot walk, the gearbox must be removed and removed to check whether the separation ring above the inner cog is broken. The fact that the fragments are capable of killing a piece of friction and sliding it back and forth makes it impossible to back off. The separation ring can be removed and the new one can be removed。
So here's what lehman's heavy work has done for you about the loader's vulnerability and the solutions, remember
Lehman's heavy work is located along the beautiful and rich gulf — the city of yantai lai — and is accessible and geographically excellent. The lehman heavy workers are committed to the corporate purpose of “quality above all, user above all, and good faith” and to the business philosophy of “human talent at its core, market orientation, quality branding, innovation for development” and are specialized in creating a research and development production base for small loaders。
