2010 crawler hydraulics

[Tom Graham]

I have a 2010 diesel dozer and the hydraulics went from extremely slow to virtually not working. At first it squealed like it wasn"t getting enough oil, so I added to no avail. Wondering if there is a filter somewhere, or if I have to febuild the pump, where is it.

Looking at the JD Parts web site it appears to be the same as the 2010 wheel tractor. Although I'm not familiar with the crawler I can say the filter should be located on the right side below the brake pedals. Their is a round cover with 3 bolts, behind it is the filter,it is a washable micro screen and very hard to get clean. You must use something to cut the wax like substance from the oil that has plugged the micro screen. When you think it is clean, stand it on end and pour oil it to the end. If it does not immediately run out it is not clean. Hope this helps, if not post back and I will help you through rebuilding the pump. You can view the parts manual on the JD Parts web site, just search for 2010 and select the crawler section.
