jis port data
i'm looking to purchase a jis standards handbook for with hydraulic port data in it. in particular, i'm currently looking for port and fittting data on the jis b2351 port. it's found on a lot of japanese produced excavators. wierdly, it employs a bspp thread. where do they come up with this stuff? can anyone tell me where to
order such a handbook?
thanks in advance,
rock.
