Jcb 530 70 road speed

[Cmoran]

I’ve just taken delivery of a 530 70 Loadall I’d say it does barely 10mph in fourth gear on the road everything else seems perfect is that max speed or am I doing something wrong?

 

[Wellytrack]

Sounds wrong.

 

[Goweresque]

It sounds silly, but is the accelerator pedal free to go right to the floor? I noticed my 530-70 was slowly getting more asthmatic on the road, especially going up slopes and the like, though fine around the yard, and I eventually realised that there is a well in the fuel tank under the cab that allows the pedal to be depressed, and this slowly fills up with soil, dirt etc and prevents the pedal going as low as it should. Cleared that out and it was all back to normal.

I’d say you’re spot on because it doesn’t seem to Rev very high without pushing hard on accelerator

yep common as muck! clean out under the cab well, also had the tank expand due to injector pump boost diaphragm blown which restricts the pedal travel. can get round that by tweeking the pedal bracket and adjusting cable a bit.

Cable. Don't know what happens to it but it's not uncommon. Mine is a 52 plate and in the top "auto" gear it needs to be doing over a certain speed to shift into too gear, and if course it never gets that fast. Winter service should put it right here.

Thanks folks I’ll give cleaning that ago today hopefully it will be easy job to do!

Is it a farm special of standard construction model? if standard with 4 speed gearbox do not expect any more than about 16 mph with a tail wind!

 

[Cmoran]

It doesn’t say farm special only 530 70. I cleaned under accelerator it made a big difference

Get someone to sit on the seat with foot flat to floor then have a look if the lever connected to the accelerator cable is touching the stops for flat out - if you can push the lever further to the stop you need to adjust cable accordingly.

Can I ask what is the difference between the two models?

 

[Sparkplug]

At that age it wasn't a great difference whereas today it is about £25k!
if yours is around 1999 ish, you can always bolt a APUH on the back so that's not a problem, FS would have 100 hp in that era, probably a joystick with 4 buttons on the top, Radial Tyres 17.5 LR x 24, Hydraulic Equipment Locking (another bolt on accessory) possibly air con as an option, maybe a 5 speed gearbox but other than that nothing major - whereas as the FS model grew there were lots of spec increase to justify the price difference including Boom Suspension 120 then 140 hp engines, 6 speed box, high capacity hydraulic pump with with load sensing, torque lock etc etc.
The models made around 1999-2008 were some of the most reliable bullet proof models ever made by JCB, but since then it has all been downhill in every respect except for the Retail Price!!

Mines definitely standard model!! But will hopefully do all I’ll ask of it! Would have preferred a bit more road speed but tractor and loader can cover that

The construction machines used to have a plain bongo non turbo 4cyl engine and as much spirit as day-old duck-muck.

It seems to have a bit of poke in fairness for the engine size. I see it been it’s used here and the jd6330 parked for all feeding near yard they are saying it’s very comfortable to drive.

Any one know where speed sensor is ,as lost speedo ,and wont go into higher gears sit in 3 rd
03 530-70
thanks

This is my one , see the writing on the side , has your got that , mine goes about 20 mph on the road , i wouldn’t want it going any faster, and it doesn’t need full Rev to do it either.

old ones will just indicate a rough speed based on engine RPM which will come via the alternator but some newer ones did have a proper speedo which probably takes its reading off the speed sensor on the gearbox.

First thing to do it make sure its rev flat out though as throttle travel is a common problem, with crap built up under the cab and often a swollen fuel tank so the pedal hits the fuel tank before its opened the fuel pump fully.

Speedo reading might not actually do anything other that give you an indication of speed. Gears might work fine with out it but i dont know. RPM would be the first to get right.

Full RPM makes a massive difference to how a torque converter transmission drives. It is always the first thing to get right.

What I mean is when I’m on the road I won’t be at full Rev but still going as fast as I want to. Not like when I had a case 580 g digger and on the road it needed full Rev to get anywhere .
