I have a 2000 310se backhoe with 5-function valve block as it has the extendable stick. I would like to add 2-way aux. hydraulic function for thumb or plate tamper use. Does anyone know the 6th spool valve current part number or sub that I will need? I understand additional parts likes studs, o-rings, hoses, etc. will be needed but right now I would like this aux. spool valve p/n. Thanks
It looks like the sixth function kit # 9 part # AT189160 is no longer available. The way the backhoe valve is designed, the swing section needs to be replaced when installing the 6th function section. Part #’s for the sections are in the screenshot below. The sixth function control pedal kit part # AT183952 (if available) needs to be installed also. The auxiliary section does not include relief valves necessary when running a thumb. One option for (2) relief valves at a decent price is to purchase kit # AT194368. To run a plate tamper, you will likely need to install a dedicated return line back to the hydraulic filter to allow the tamper motor to freewheel when the aux control valve is returned to neutral.
At the cost of this, it may be better to sell and find another already set up fit auxiliaries. YMMV
For the plate compactor, would it be a better choice to run a selective control valve instead?
Foot switch control may be easier to operate for longer periods. Selective control valve kit # AT192382 (includes electrical control), not sure on availability.
