JCB 3CX 1987 fitting hammer lines -HELP

[tonidukic]

Hello guys, I need your help and opinions.
I want to add hydraulic hammer pipes onto my 1987 JCB 3CX - standard dipper. I have Montabert BRH 125 breaker to fit onto her (40 - 100 l/min).
I am confused because my machine have single hydraulic pump (91 liter/min capacity) .
What is the best way to fit hammer lines onto machine?

Thanks

I once hired a 3cx with the hammer tee’d into the main dipper,push down and oil went to the hammer,was great to use.

If still stuck, lads on "Vintage JCB Machines' on Facebook are very helpfull

At one time they used the extender lines, you locked them off with a pin so they couldn't extend.

That usually had a tandem pump as well but not an option to the op. If the following works go to Fred's post. He has forgotten more than most have learnt. (aka Fowler Man).

Perhaps the OP is having short term memory loss, or am I missing something obvious....isn't the OP on this thread the one in the same OP from 5 months ago on Classic Machinery...

if so hasn't this been explained to them already perfectly well by that post from FM....ergo tee-in, pipe up and go?

Hello, here is my reply on your "nice" behavior, and yes, you are missing something.
Well, I can tell you that I am surprised how can you adress me with memory loss? No, I don't have memory loss.

Just wanted to hear few more professional opinions how to add aux. Hammer lines on machine with use of flow diverter valve, because TEE of the boom ram is not professional way of doing it, and neither JCB predicted doing it like that.
Nevermind, thanks for your opinion.

You’re welcome. When you’ve gone around the internet and asked the same question half a dozen times and come to the realisation that the method offered to you on CMN is both is simple to operate, easy to pipe up. Come back and tell us all about it. Somehow I doubt you will though. Good luck.

I had not realised you are the same poster as on CMN months ago, I am not as sharp or as retentive as Pheasant S. You were offered more than professional advice by one person on CMN. Yes it would not be the way a machine might have been set up from new in a factory but it gave you the most simple lowest cost option for an old machine.
For future reference for all us amateurs out there give some follow up on how you get on.

Reality is your machine is now vintage,not being a “professional way” won’t make a shite of difference to machine value,it is however a simple and cheap way to fit a breaker to your machine.

If I offended someone please accept my apologize, it wasn't my intention for a single second, just wanted to hear few more opinions.
I am reading this forum for a decent time and have only good thoughts of people here.
Now, I have two more questions If someone still would to answer me ;
1. On which port on the boom down cylinder "Tee" valve have to be fitted (picture attached) ?
2. Can someone give some more info about "T" valve that need to be used ?

Thanks

The correct way to operate a hyd hammer is to install a hammer valve which are priority flow regulators with relief valve and are solenoid operated. These valves re normally installed between the hyd pump and main valve chest. The regulated A port supplies the attachment and the B port supplies the main spool valve. When de-energised the controls operate as normal. When the hammer valve is energised the hammer is supplied with the correct regulated flow and the remaining functions still operate BUT with lower speed.

Yes, I would also want to add a 12V 3/4" hammer valve, but I am not very sure would it work on my 3cx because I have a single pump (90 liters/min capacity), and a breaker is Montabert BRH 125 (40l/min minimum).

I guess it is not very hard to plumb up valve, but if I dedicate enough liters to breaker, would my rear arm work fine is my biggest concern.

Without a hyd schematic for your JCB. I tthink you should have enough flow for the breaker from the single but pump. When operating the breaker the back arm will operate slower when you are operating the hammer. I've only seen these hammers operating and normally you don't operate the back up to much when you use the hammer function.

From my experience with a hammer on a 360, you position the hammer and then fire it and as you say don’t need much flow to the arms as you mostly only lower the boom till your though what your breaking out. Once though foot off the peddle for full flow to arms re-position and repeat !.

There is the official scheme in attached files in this message. This on pic is old manual diverter valve I guess. Feed from pump into hammer valve, one hose goes to excavator valve, second to hammer. Electric 12V valves have little drain pipe, still breaking head where to fit that ??.

And does anybody maybe have experience how to connect electric wire supply to hammer valve?

Ive got a 1994 4CX which had breaker pipes on, used a breaker a few times but not much and took the lines off a few years ago. No idea if would fit your machine or not but would sell them if they were any use to you.

 

[tonidukic]

I don't need them, already bought 2 used hammer lines so I have a lot of pipes both steel and flexible. I am just missing hammer valve but I found supplier for it If decide to put it on.
Anyway thanks for your offer, I believe you would sell your pipes easily because they are wanted a lot.
