Our Service
Overhaul
Aliauto deals with the repair and testing of hydraulic components of many types, with the largest displacement currently available on the market. Our company is constantly growing, therefore we are committed to maintaining the flexibility necessary to guarantee a punctual and personalized service suited to the needs of each individual customer.
Thanks to our brand new test bench, we are able to test all types of hydraulic pumps and motors (Bosch Rexroth, Hydromatik, Danfoss, Linde, Denison, Hmt, Poclain Hydraulics, Eaton, Parker, Kawasaki, Staffa, Sai), distributors, control valve blocks, reducers, valves, servo valves and hydraulic cylinders.
Upon receipt of the units, we check and code them. After that, our sales department contacts the customer to understand the urgency of the overhaul and the reasons for the failure to function. Once all the data has been collected, our production department proceeds with the disassembly of the unit to assess the actual damage and to identify all the worn components that need replacement.
Once the components to be replaced have been identified, our technician will send a list to our sales office containing the list of worn parts to be replaced and the work to be done. On this basis, we check the availability of the components in our warehouse (or at our suppliers in the event of a lack of stock) and prepare the estimate that includes, in addition to the economic offer, also a brief report of the causes of breakage. After that, we send everything to the customer via email.
The customer accepts the order in writing, as estimates are never agreed upon by telephone. The order confirmation with the delivery date of the repaired unit is prepared and sent to the customer.
At this stage, we take care of collecting the material to be replaced from the warehouse, and proceed with cleaning and reassembling the unit according to the manufacturer’s standard procedures. In order to achieve maximum reliability and precision, we are equipped with lapping machines, grinding machines and lathe, based on the work that the component will have to carry out.
In this phase, we proceed with Unit Testing using the manufacturer’s predefined tables. The experience gained in more than 10 years of activity in the field of overhauling of hydraulic pumps and motors has allowed us to design and build a New Test Room.
At the end of the repair, we test the units through our brand new test bench; the tests can be static, dynamic or functional. At the end of the test, we also issue a detailed test report containing all the data and values detected during the test, in pdf and excell format. Thanks to the versatility and power of this new system, we are able to test many types of pumps and motors with the largest displacement currently on the market, providing the customer with a real guarantee on the operation of the unit after repair.
Overhaul
Thanks to our expert, qualified, reliable and fast service, we are a sure point of reference in the repair and testing of the main hydraulic and mechanical components for the following sectors: earthmoving, agricultural, industrial, naval, railway and goods handling.
We also have an efficient, modern mechanical workshop with CNC and traditional machine tools, equipped with lapping and grinding machines. In our workshop, we carry out dimensional checks on internal components and verify the actual state of wear. We replace or overhaul elements that do not fall within the tolerances prescribed by the unit manufacturer, using only original spare parts.
Overhaul is always covered by a 12-month warranty. After this period the assistance service continues at the customer’s request.
Dynamic and Functional
Testing
Thanks to the experience gained in the field of hydraulic repairs, Aliauto has created an efficient and versatile test bench for its workshop. It is unique in terms of features, performance and installed power and is used for the functional testing of hydraulic pumps and motors.
Thanks to a software specifically designed for our needs, we guarantee constant control and continuous data acquisition. During the tests we can also simulate the hardest and most demanding working conditions of the unit; thanks to these features, our test room is our strong point.
The versatility and flexibility of this new bench, we are able to test pumps and hydraulic motors of many different types currently on the market. At the end of the repair we provide the customer with a real guarantee on the functioning of the unit and we attach a test certificate that attests the conformity of the test methodology adopted.
