I replaced the piggyback pump along with a 17 gpm front pump. Now the pump squeals until the fluid is warm. It acts like it is starving for fluid. Is there a high flow or high capacity filter for this tractor?
 
Not sure if it is the same filter as the bigger tractors.But Otto Wenz (Wenz Service)sells high flow/ high capacity filter kits.
 
At one time there was someone that made and add on filter dapperer where you stacked two filters on top of each other. . Usually the flow capacity on the stock filter is around 15 GPM , so yes you are starving the pump . There maybe a industrial filter housing for the 656 as the industrial tractors used a higher output pump. I do not work on yellow iron so i am not up on all the stuff that you could interchange.
 
here is a filter extension that may help. http://www.allied-precision.com/56033.htm It doubles the surface area of the orginal filter and allows more flow
 
Add an extra gallon of hyd oil to it,wont hurt a thing, and it will probably fix the starvation problem.
