I went and had a look today
There are 3 pipes going to the tap ?
The pipe work up the boom and dipper
Has 1 very big pipe and 1 small one.
Which makes me think that it is not 2 way ???

Under a cover there is a tap.
Would that just turn off the hammer pipe work
Or is it for 2 way ???

Clive ,
I do not think it is.
Can i fit anything to it.
I want to make a short digging arm from a 1.5 ton
So i need to work the bucket ram on the end.

I have a YANMAR B30V
Is there any way i can use a grab off my hammer pipe work ?
I need it to open and close.

clive,
Is that hever castle ???
