JCB JS130 grab

[Derrick Hughes]

Does anyone understand the pipe work on a JS130 for attachments i have 3 pipes with quick release either side the quick hitch . Are the twin acting or single
Want to fit a twin acting grab on

Sounds like one is a breaker line ,the other two sets will be for a selector grab ,if so then you have a double acting line ,,breakers only use a single direction flow.
Pictures will be an advantage

Yes pictures be good, I want to do the same but only have the two fat pipes, one on each side, for the breaker.

I have 4 fat pipes but one has a square block 2 ft from the end with a 3rd pipe coming out of it

We had the same on our Js130. Our dealer converted it to double acting so it can be changed. Ended up with two valves beside the cab to change it back to single acting for a breaker. I would take some pics but we’ve since sold her!

Did you know the cost to get that done? I’m the told the single breaker line would work a tree shear with a strong spring but I don’t know on that one.

Cant see that working ,,breakers are pressured one side with the free flow return ,,even a big spring couldnt close a ram and push oil back up the feed side

Doesn't need- to all oil dumped to return. Single acting ram with spring return.

So would it have two pressure pipes with two returning. Both one way

Bossman reckons it was around £1,000 for the dealer to do it

It’s on my to do list, along with far too many other things, new grainstore going up at mo so that’s taking up all the time and machine.

A breaker line is flow-return ,,thats one pipe each side ,,a selector grab has 4 pipes ,,2 to work the grab jaws ,the other two to rotate ,,these are sometimes smaller to reduce the flow else it would spin to fast .
Look how this is piped

Sum it Equipment ltd. To convert breaker line to 2 way is £1095 plus vat. To add a second line providing the solenoids are there on the block is circa £1750 plus vat.

How do I get the joystick buttons working

What are you gonna be using a grab on it for Derrick?

Might be an isolator rocker switch to activate them , a rotator grab could be controlled by the foot peddle or a roller on the joystick

Clearing timber . Given up for now . Using it without the grab on .
Simple things . Why they just can't put a chart in the cab saying what the 8 pipes do

What about a hydraulic (or even fixed) thumb instead?

I'm sure a JCB tech will tell you what pipe does what if you asked nicely and gave him a cube of logs to take home?
