Default JCB C3 Mark 3

Hi,

I have just bought one of these, about 1980. I am told it was one of the last ones of this shape. It has a shuttle leaver to go forward and backwards.

It has gears also, but can not see a clutch, so have just left it in one gear, which seems pleanty fast enough.

Few problems:

1) Steering goes very hard and then loose.

2) Gets hot!!

3) Leaking hoses, I am told best to get new ones made up, as spares are hard to find.

4) Can not work out how to move back actor along. Assume there is some way of un locking it and sliding it about with the actor.

5) Breaks dont work.

6) Probably needs a service as I don't what has and has not been done for a while. It certainly has not seen a grease gun in a long time. Are there any baisc guides to show how to service these? What oils to use etc.

Any help or mauals would be great news.

Looking forward to hearing.

Cheers

Hi Astimson, welcome to the forum, you will find lots of friendly people around here. If you let me have your e-mail address I will forward the ops manual for this machine to you, that should help some. With regards to the steering problem, what is the hydraulic oil level at, first thing to play up when the level is low on these machines is the steering! Rad blocked or thermostat u/s for too hot. Hydra clamps need to be released to move the back-acter along the rails. If shes not been looked after well, they maybe seized. All this info is in the manual Cheers for now. Mark

Thank you so much. So what do I do to sort out over heating, worried I might kill it as it was smoking after two hours. What oil for breaks and any clue on steering. These three things are worring, the other bad bits I can cope with!!!

Mark,

Thank you, I want to preserve this old girl, want to make sure I dont killer off. So the manuals would be so useful, I think it has the leyland engine.

When it arrived just after it came off the lorry it ran dry, so already bled the derv though so now know my way around a little bit.

Most worrying bits are, over heating, will this cause damage? She was smoking after two hours of very light work.

No breaks scares me!

Steering goes light then very hard.

Is there a basic service book?? I should follow as I dont know is any has ever been done, certainly this is the only grease in serveal years she has seen.

Any tips very welcome and thank you for your time. Any info much apprciated, if you have anything you can e-mail that would be great.

astimson@savills.com


Cheers

If it's overheating you want to be very careful. I presume it has a heat gauge (if not I advise you invest in one.

the radiator needs a blow out to start with, and if you suspect that won't work then take the radiator out and flush it through with a hose pipe in reverse to what the engine normally pumps water through.

As for the brakes, I've been told the 3C's where a bit prone to it (being that it's only tractor brakes) So once you get them working you'll need to use the gears for braking/holding it back whenever possible.

Somewhere, Hidden Deep inside grandfathers attic is a 3C operators manual and possibly a Workshop Manual. I'll see if I can find them for you.

Also when you have five minutes, Spray the back legs with Oil or paint on some. Just makes the operation smoother, if it's really bad then wire brush the legs.

The manuals would be amazing. Mark Rive, said he has some he can PDF to me, but no sign of them as yet, not sure if he got my messages.

No heat gauge it just start to smell hot and smoke came off the engine. Assume all the years of oil and filth buring off.

I will try all the tips. Thank you so much.

Is the steering and and actor and bucket all driven from the same hydraulic oil resivor?

Or is the steering on a seperate system? When some oil leaked out it looked brown in colour and seemed to seperate, as it there were two types of oil. Advice change all the oil??
