Question about the breaker circuit (JCB 8015)

[Blairvoyach]

Hi everyone,

My first post and it's a diggers for dummies one

I have just bought a JCB 801.5 mini digger and would like to fit a hydraulic thumb for handling logs etc. I have the service manual but can't get any sense out of it.....
The digger is "piped for breaker" and what I'd like to know (dumb question time) is whether the breaker circuit is two way, i.e. if I fitted a push/pull hydraulic ram, could I operate it in both directions via the foot pedal? It seems to move both ways.

Regards, Jeff.

Welcome to the forum Jeff ... It depends on the spec of your machine .. you will indeed, need bi-directional flow.

When you rock the pedal in either direction with nothing connected .. does the engine labour slightly which ever way you rock it ? If it does .. you're possibly in luck. If it doesent, there may be a tap some where that alters the flow on the return line.

If all of that fails, there may also be a blank hose termination somewhere that connects with the pedals opposite movement.

Yes, the engine does labour so might be onto a winner here

Thanks for the help!

If its anything like my 8018 then it will be 2 way thing!
