John Deere TA10139 Hydraulic Pump

John Deere TA10139 Hydraulic Pump refers to a pump assembly featuring 63 cc and 145 cc displacement units. Information on this pump indicates the weight of 108.227 lb and gives the part number RE587657 as a reference for TA10139. The combination of two units into one assembly makes it possible for the machine to handle various hydraulic flow requirements through a single drive.

Different displacement values influence theoretical delivery per revolution; however, the pump needs to be chosen in the form of a unit assembly. TA10139 is the equipment model and serial number range that need to be confirmed. It is important to take care of shaft, rotation, mounting, port and any control connections to make sure they correspond with the existing assembly. The marking of connections before pump assembly removal is necessary in order to prevent the confusion of 63 cc and 145 cc units, which results in incorrect operation of the machine.

It is required not to install a replacement pump without establishing reasons of previous failure, since contamination, improper inlet, overheating, incorrect pressure settings or a drive alignment might harm both units. The inspection of the reservoir, filters, hoses, cooler and relief valves is also required. If the removed assembly failed internally, particles must be cleared from the hydraulic circuit and clean oil used for commissioning.

The pump needs to be primed where necessary and started up at low loads. The technician will need to determine rotation and test out the reaction of each section of the pump. Proper pressure, proper sound, proper temperature and proper leakage indicate that the pump and the hydraulic circuit connected to it are working properly. Any weak performance will need to be checked for any possible leaks in the valves, actuators and controls prior to the pumps being considered faulty.
