Recently bought an 03 link belt 210LX excavator to clean up some building sites, groves, and fencelines. It currently has a single function aux hyd system on it now. Wanting to add a hyd thumb if possible, got a quote for 8k just in parts (not inluding thumb) to add a dual function system. Wondering if there is a cheaper/simpler way of adding one myself. We are very mechanical and would like to think we could add some kind of diverter valve and get by that way instead. If it will be too big of process we'll just add a mechanical and move on. Any and all advice is welcomed. Thanks!
Good day Dan Often the two way operation of the option circuit is in place just need some connections, if you could make photo's of the option line and connections it would be easier to help.A circuit schematic would be real helpful, attached is some information you can find much more by going to the web site excatech.org > Library > Adapted applications. Kind regards Uffex
Attached is from a 160 it could be very similar to your machine. Kind regards Uffex
This is currently how it is plumbed/set up. What other photos would you like?
Hi Dan You have what appears to be a third party hammer setup (Hammer being one way - third party meaning not a factory fit option it is something that has been cobbled together just for hammer control). That aside lets see if we can get your thumb working - please follow the option lines back to the main control valve and make a photo of what you have , the only question we have for you is how would you prefer to control the thumb - pedal. - switch - or combination with the bucket ? Kind regards Uffex
I would prefer to run with a switch of some kind on the joystick if possible, however foot control would work as well.
Good day Dan If you could make a photo of the connection to the main valve it may help this end, a switch on the joystick would require thress possions >off default > open thumb cylinder > close the thumb cylinder. I believe your nmachine would require a port relief valve to the piston end as you could make a lot of pressure by running the bucket cylinder against the thumb. A phono would make it clear if you already have this in plavce. kind regards Uffex
Good morning gentlemen, I have a link belt 160lx serial number K2J16053, it has bidirectional hydraulics, wondering if anyone can help me along with the what I will have to do to convert to one way flow to run a hammer? Any help would be greatly appreciated. Thank you in advance.
Good day A simple solution would be to install a three port manual valve to the tank side, connect the additional port to the tank. When using the hammer, turn the return line to tank connection. Kind regards Uffex
Uffex, Thank you very much for the timely response. I will update as soon as I install the T with a line to return to the tank. Mike
