How We Carry Out


ALIAUTO carry out overhaul and test on hydraulic pumps and hydraulic motors of many different types with the largest displacement currently on the market. Our expertise allows us to offer a repair service that is suitable for every problem.

Upon receipt, Units are checked, sorted and coded. Customer is contacted by our sales department to understand the degree of urgency and the reasons for the non-functioning. Our production department is informed of the reasons for the non-functioning and disassembles the unit to assess the problem. It also takes into consideration the worn components that must be replaced.

Quotation is prepared after the technician has checked the wear of the unit components to be repaired and transmitted the list of spare parts to be replaced and works to be performed. ALIAUTO is also a point of reference for consultancy: specialized technicians “diagnose” the type of failure and its seriousness and precisely inform the customer of the situation, attaching the repair plan and the related quote.

Warehouse checks the availability of the components. The sales department draws up a quote, listing the material to be replaced and a brief report of the causes of breakage. Everything is sent to the customer by fax or e-mail.

The customer accepts the order in writing. Quotes are never agreed upon on the phone. The order confirmation with the delivery date of the repaired unit is prepared and sent to the customer.

Material to be replaced is taken from the warehouse. Cleaning and reassembly of the unit following the standard procedures of the OEM. 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.

Unit testing through predefined tables of the OEM. The experience gained over more than 10 years of activity in the field of pumps and hydraulic motors overhaul has allowed us to design and build a New Test Room. This test room is our strength, thanks to our excellent Control and Data Acquisition systems of the unit under test and to our software, which is specifically designed for our needs.

Tests can be: STATIC, DYNAMIC or FUNCTIONAL and is carried out with a test bench. We are able to issue a detailed test report. Thanks to the versatility and power of this new system, we are able to test many different 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 the repair. All data and values ​​detected during testing are recorded and a certificate is issued and attached to the repaired unit.

Unit is dried, washed from the residual oil from the test and prepared for shipping. Because of the high cost and importance of the components, great care is given to the packaging phase.
