JCB 1CX - Have you used one?

AussieChris · Jan 17, 2017

Mine is a 2011 (sold new in 2012) and has the servo/pilot controls same as the new ones at CEA.

I too have read that you can operate them with the seat at 45 degrees but that doesn't work on my machine. The seat has to be fully forward or fully rearward.

You can override the controls and drive the machine while facing backwards (or operate the excavator while facing forwards) but not at the same time as you can on the older non-pilot series so there are advantages to both models.

I hope you can find a good machine. I wouldn't be without mine and I don't know why they are not more popular.

Hi AusDave,
Thanks for your response, I have bought some gauges and have some data from a manual to do some tests on the hydraulic circuits. I'm a little confused as to the testing of the M.R.V. circuit, one part says maximum working pressure is 350 bar and then it mentions later about M.R.V. at 1500rpm is 207 bar with various other control bar numbers stated.
Do you know how to go about this test and which pressures I should use for maximum setting.
What is the park brake circuit Bar pressure, the manual I have doesn't list it
I also have received a filter so I have some work ahead of me

I don't have much history on machine unfortunately, it is a standard pump machine and has done approximately 4000hrs
Cheers

Hi Lewy,

I have a similar machine to yours (year and engine) and I am experiencing the same issues yours seems to have. Did you find a resolution?

Thanks,

Greg

Hello, I am a new owner of a 2003 JCB 208s and was wondering if anyone has a copy of the service manual and/or user manual. I'm excited to go over it and make sure everything is good.

Big T · May 21, 2017

A HUGE THANKS!! to AusDave for being such an amazing help to everyone across the world with this thread. I'm going to be picking up my JCB 208s tomorrow and will update on how it goes.

Hello all! I joined this forum to see if maybe you could help me with a problem i am having with my 1cx (serial 0752898) the loader hydraulics seem to be weak and slow while the parking brake is released (switch off) however, if the parking brake switch is on (brake applied) the loader operates quickly and strong, (normally). I have the floor board out of the machine. I am leaning toward some kind of restriction in the float valve. I have no informatiin or manuals on the machine... the front bucket has a clam shell attachment. I have also noticed that if another hydraulic function is dead headed, the loader operates normally until i release the other function, then it returns to sluggish and weak. Also the loader will not move at all with the brake released until i rev the engine up. Any help will be greatly appreciated!

Hi guys, another new fella here !
I've just bought a 1997 1cx with 1200 hours Perkins and was looking for info online when I came across this forum.
The jcb is in good condition with 4 in 1 and 450 mm backhoe bucket. It also came with pallet forks and a screed bar.
Does anyone know if there are any compatible excavator buckets to fit the backhoe or does it only take genuine job buckets that suit the 1cx?
I believe the front loader is standard bobcat as I will be looking for a grapple as well.
It didn't come with a spare wheel... Again does anyone know if they are just jcb pattern or similar to another skid steer?
Any help or advice would be appreciated
Cheers Mike

Hi CSmith.
The problem could be hydraulic or electrical or both!
Best to check the hydraulic pressures and circuitry related to the hydraulic system to narrow down the cause. It's not a wise idea just to start taking bits apart on the hope it could be the cause. Diagnosis is your friend.
Send me a message with your email and I can send you some JCB 1CX operation and service manuals which may help you sort out the problem.

Hi Mike, good to hear another Aussie on the 1CX thread

Sounds like a nice machine with some useful attachments. Any excavator bucket which has the same pin size and spacing will suit your machine. However there never seem to be any around when you need one. However it's not hard to find a bucket thats matches the size of your machine, say off a 1.5 to 3 tonne excavator, and with a bit of work with the gas axe and welder make up ears and pins to suit your machine.
The front end takes Bobcat attachments so you should be able to take most skidsteer grapples.
Don't know if the wheels are similar to Bobcat ones. The easiest way to deal with punctures on a job is to have a tubeless tyre repair kit, plug the holes and put the air back. Faster than changing a tyre and will fix most punctures unless they are long cuts.
Send me a message with your email and I can send you some JCB 1CX operation and service manuals.
Let me know if I can help you further, AusDave ph: 0411 572 725

Hi Dave
Thanks for your reply and info, I will keep an eye out for buckets for sale on gumtree.
I don't seem to be able to send a direct message as I'm new to the forum however I'd love to get copies of the manuals from you.
My email address is branchingout01@outlook.com
Thanks again for your help mate

Hi Mike,

When I was looking for replacement dig buckets I was unable to find a match with any other machine. On my 1CX (a late model) the pin set out for the bucket is as follows...

Pin Diameter (P/D) - 35mm
Between Ears (D/W) - 135mm
Pin Centres (C/C) - 130mm

I realize you're looking for a 2nd hand one but I ended up getting a brand new 350mm bucket custom made locally and although it cost about $900, I'm really happy with it and it's super strong. I've attached photos to show how it is a more conventional excavator shape than the original JCB squat shape (which is bizarre). So like Dave said, you should be able to get hold of any suitable sized excavator bucket and re-do the ears to suit the 1CX.

Congrats on the new acquisition by the way.
Chris.

Hi Chris
Thanks for your reply and information regarding buckets. The one that you had had made looks really great and I see what you mean about the depth of the bucket. I will keep an eye out for a used 600mm that can get modified otherwise If I cant find one I will get one made like you did.
Cheers ate, regards Mike

Hi Guys
Just doing some more research on backhoe buckets for the 1cx and noticed that in the operators manual that AusDave very kindly emailed to me that JCB 803 and Kubota KX71 / KH60 / KH66 mini excavators share the same buckets and are compatible with each other. They have the same pin dimensions etc as Chris stated in his post above.
I just thought that I would share this info with you guys just incase anyone else was looking for buckets to suit their machine.
Regards Mike

Thanks Mike.
In defence of the squat JCB buckets, of which I have a few, the shape of the bucket maximises the breakout forces at the teeth which is really helpful digging out stumps, roots and trees. Tiger teeth are also helpful.

Hello AusDave,

If've seen that you helped may people by sending them the manuals of the JCB 1cx via email.
A friend of mine is a happy owner of one of these machines since last Friday, and I'd like to surprise him with the manuals.
My email address is fda@freemail.hu
I'd really appreciate if you could send me the files.

thank you very much in advance for your help!

Hi,
I'm buying a JCB 1CX and you could clarify 2 things in my mind :
- I've heard about mechanical play issue in the backhoe rotation system on 1CX early version. The problem has been fixed by replacing the mechanichal gear by an hydraulic worm screw. Is it correct? since when can we found the hydraulic worm? I'm worried about having found a year 2004 1CX with mechanical gear for backhoe rotation system. Is it possible?
- concerning engine type. Is there a period when 1CX could be equipped with Peugeot or Perkins (as an option) engine? Since when can we found 1CX with peugeot engine? after 2000 or not?

Hi Bruno.
I don't think JCB has changed anything with regard to the backhoe slew mechanism which is what you refer to as the backhoe rotation system. It has always been a rack and pinion style and the same system is used on the tracked version of the 1CX as well. Like any component it can wear and develop some play. It is a very simple & durable system and easy to maintain and service.

Early 1CX machines in the 1990's had Peugeot engines but I think virtually all machines were Perkins especially after 2000. It's easy to tell a Peugeot 1CX as it has the exhaust coming from the side of the engine cover whereas the Perkins engine comes through the top of the bonnet.
If the 1CX is well maintained they are an extremely useful and reliable backhoe.

Regards AusDave

AussieChris · Jan 17, 2019

Hi Dave. Good to see your still around helping us 1CX tragics!

Do you know if the slew rack and pinion can be shimmed at all to reduce play? Mine has a bit more slack than I would like but not enough to warrant replacing the rack and pinion parts.

Hi Chris.
From my experience and looking at the service manual there doesn't appear to be any way to adjust the slew play. I think it's the nature of this type of slew system. Being so close to the backhoe pivot point means a tiny bit of play is magnified many times over a couple of metres away at the bucket. Plus the fact that there is a bit of bounce in the hydraulic system as well. It just takes a bit of practice to get used to it and then you can place your bucket within a centimetre or two of where you want it.
Other slew systems with two rams, such as larger backhoes like the 3CX, can have less play but can wear quicker at the pivot points as they are often covered in dirt and mud and not necessarily greased as frequently as they should be.

Hello,

I am interested in buying a used 1CX, and was wondering if anyone could give me some advice.

There are a couple near me (Portugal), and I was wondering what I should look out for. What are some of the common problems that older 1CXs have?

One I am hoping to go and look at is a 2007 with 2800 hours for €22,000. It has been 'refurbished', which going by the photos means repainted. The positive is that it looks very nice, the negative is that it could be hiding all sort s of rust and corrosion. Although rust is not a huge problem in Portugal, certainly nothing like in Northern Europe.

Were there any major changes throughout the production run? Are there any model years that should be avoided?

Also (AusDave I'm looking at you), does anyone have an operator's manual and service manual for a 2007ish model?

Cheers.
