The tractor is likely the workhorse of your farming operation. Tasked with everything from plowing the ground to scooping and moving materials, tractors are one of the most heavily relied upon pieces of equipment in any agricultural setting. One thing that makes a modern-day tractor capable and functional is the hydraulic pump. This pump allows the tractor to lift and lower large loads and heavy extension attachments like scoops and mowing decks, so if the hydraulic pump goes out, you have lost a very important function. You may be tempted to do a rebuild of the hydraulic pump on your own, but it is far better to trust this complicated task to a pro. 

It is actually really easy to damage the pump itself. 

When you do a complete hydraulic pump rebuild, you have to: 

  • Disconnect the outer components
  • Open up the pump casing for cleaning 
  • Drain the interior fluid 
  • Replace all worn gaskets and parts 

Through this whole process, it is very easy to cause damage to the pump's main casing. If this happens, you will have to opt for a full replacement which is bound to be more expensive. 

Low or high levels of hydraulic fluid will compromise the pump's function. 

It seems like such a simple thing to do, but even adding the hydraulic fluid to the pump after the rebuild is complicated. The fluid has to be absolutely the correct type. Something like a fluid with the wrong viscosity or heat-withstanding capabilities will lower the functionality of the pump. Beyond that, you can also lower the hydraulic pump's overall functionality if you do not add enough fluid or add too much. If you have no experience with refilling a pump's fluid, it is easy to make this common mistake. Unfortunately, you may not realize the problem until the pump is completely back together and back on the tractor. 

Hydraulic gasket seals can be really tedious to work with. 

Getting the hydraulic seals back on the pump in the perfect position is also a challenge. These gaskets can be rather flexible, and their contact with hydraulic fluid can give them an oily feel. The seals and gaskets have to be precisely placed because the slightest misplacement can allow the hydraulic fluid to leak. A misplaced hydraulic seal can also cause damage to the seal itself when other components are put back in place because it can get pinched between the two surfaces.
