Hello,
I've been reading these forums for quite sometime and have gotten good advice from them.
I just recently bought an '84 John Deere 310B backhoe with slow hydraulics. It has approximately 2200 hours showing on the meter. The steering and reverser seem to work fine. However the loader and backhoe seem slow and under powered. It chatters and vibrates a bit and make me believe the main pump is starving for oil. The previous owner had the main hydraulic pump rebuilt a few years back. I know I should probably test the pressures at the reverser and main pump from reading post, but wanted to start with changing the oil, both filters, and cleaning the suction screen. I have a service manual, but it lacks great detail on where the suction screen is located. Best I can tell, it is at the bottom on the case and is installed sideways or perpendicular to the length of the backhoe. Is it removed from the right or lefthand side of the machine? Can someone give me a picture or explain how to remove this screen? Is it located behind a fitting that a rubber hose attaches to from the sump to main hydraulic filter (horizontal filter)? If so, it appears the filter housing will have to be removed to get the screen out since the housing is directly across from this fitting and the rubber hose is only 4" long or so. Or can the screen be removed from the left side of the tractor by removing the fitting from that side?
Thanks in advance,
Cecil
