    Here i go.
    The first problem i found was the shuttle lever not working right.
    Found that the reverse gear sometimes didnt engage very well, crunching when u release the clutch pedal as gear wasnt at its full travel.
    So as been adviced here removed floor mat (no tools needed), remove the 10 10mm hex bolts retaining floor plate and you will find 2 cables.
    The one on left is the 4-5 gears, the right one is the shuttle cable.
    Seems the problem with the shuttle was on the cables. The bolts that hold the collar in place were a bit loose but not too much. Retightened em and became better but still had difficulty on shifting reverse. Found that only crunched when you try to engage reverse and the lever is not at its full travel and you release clutch.
    If you have problems engaging reverse you will have to adjust the lever to stay a bit more forward and allow it to give more reverse travel. Loose the collar retaining bolts, loose the collar locknut.
    If you need to make more reverse travel on the lever u will have to rotate the collar in the direction that aproaches the locking nut you have just loose. If you need forward travel (Forward on the shuttle giving trouble) you will have to rotate on the opposite direction.
    I passed from difficult reverse to no forward in a little more tham 1 turn, its a narrow adjustment.
    Try in steps of 1/6 of turn until works good on both directions.

    As older it gets the adjutment will become narrower as you will have wear on the pins that hold the cable on place.
    Leave it too long crunching and expect a good bill replacing the synchro

    Gearbox and EHC calibrations.
    After tweaking the shuttle cables decide to make a clutch pack calibration.
    On Quad models like mine proceed:
    Engine off, parking brake on, press and hold clucth, upshift and downshift, start engine and cal would appear on the instrument cluster screen.
    Release buttons. Move all levers forward (F, 5th, hi range). If you put high range u will calibrate c3 and c4 clutch packs, leave it at neutral c1 and c2.
    Set engine speed to 1200, release clutch tractor shouldnt move.
    Now hold upshift to calibrate first clutch pack, same procedure (after finish first) with downshift for calibrating the other clutch pack.
    Once you are holding the pwershift button numbers will start to increase on the screen. Minimun is 120 max is 180. When the numbers stop increasing clutch pack is calibrated.
    Mine went mid 140s for c1 and c2, mid 150 for c3 c4, so they should be at half life.
    Electronic lift AUTOCALIBRATION:
    My lift was out of calibration, dint showed less tham 23 on the lift screen being the arms at lower travel, also dint have fender controls working. An autocalibration set it back to work.
    Press in cab fast raise lower switch to lower. Turn key on but do not start engine.
    Go out the tractor and disconect left or right position potentiometer. Its a round plug with 3 wires on it.
    You will hear the buzzer inside the tractor warming you error code 25. Now reconnect the potentiometer. Turn key off then start tractor. Error code 24 will appear and hitch disabled light will flash.
    Turn all knobs on the hitch control panel full clockwise. Set engine speed to 1100. Now move the hitch position lever slowly up and dow until the hitch disabled light goes off.
    Move lever full back and 99 position should be displayed. Now to position has been calibrated.
    Move lever full forward past the mechanical detent, hitch disabled light will flash again, move lever back until light goes off again. Now move lever full forward to the mechanical detent. Thats the point where full lower has benn calibrated. 0 will be displayed.
    Now move lever until 70-90 height, leave it for a while. Hitch will move up to 3 times doing some calibrations. Move full back until 99 appears on the screen.
    Hitch calibrated.
    Now i tested fender controls, they worked fine, but found that u have to move the hitch full up from the fenders, move the control lever full back to restore the lever control?
    I dont have the owners book, just the workshop manual so if there is any other way to restore control from fenders would be welcome.

    Drove the tractor 13 ish miles home and I thought the gears were a bit harsh so I tried to calibrate it but I couldn't get Cal to display (I held down the clutch and up shifted/downshifted to no avail) where should the shuttle and range lever be when doing this? Also only when i change from 4 to 5 it crunches before it is properly in would this mean that the cable needs adjustment, its fine when going straight into 5th before starting off and changing down to 4th?

    Can't see any mounting points strong enough for what I want so I'll try to bolt through to the wing somewhere .

    It does have the speed screen, I can see km/m light up when turning key from stop but it goes dead after

    Re: Ford New Holland 8340 SLE help thread

    Sorry to be a pain on this thread but i think i worked out what causes the crunch going into 5, when I change down to 4 because of deceleration/gravity (down hill) my body is pushed forward and more of my weight is put onto the pedal pushing it more down (bottom), so I moved the seat forward and pushed the pedal right down to the bottom when shifting and it didn't crunch but 1 mm (fells like) higher and it crunches so I only need to adjust the clutch (hope that helps anyone who has the same problem). Can't wait to try the baler , hope the sun will be shinning

    P.s. Thanks for the replys to my previous questions Mr.Dexta-7840 esquire

    You could be right? but isn't a SLE the old pre-TM-pre-60series?? with a clutch pedal operating switches?? If it is its a matter of needing to adjust the bottom of travel switch?

    Blimey, going back a bit now!! really need someone like rassiel or prongey to confirm

    Here's a picture of her today and the makeshift radio aerial that came with her (radio works by the way) gave me a good laugh (had to look twice at it), as you can see the blue needs re spraying but except for that it's a tidy machine, I even found out it has a working turnable air seat fitted .

    Re: Ford New Holland 8340 SLE help thread

    Can someone explain how that gearbox works? I have been looking at it for 10 minutes and still can't figure it out.

    What is the lever furthest away from driver, what are the buttons on the 1234 - 5678 stick for and what is the rocker switch on the dash behind it for?

    nearest lever is throttle
    next is f/r
    next is semi powershift 1234,then5678 after moving lever forward
    then there is hi/low

    Oh I see so the 1234 / 5678 lever only has two positions but then the buttons do the powershifts. That was what was confusing me

    Re: Ford New Holland 8340 SLE help thread

    Is this a 40 series help thread? Good. Can I ask a couple of questions. I'm really crap on tractors.

    My 7740 blue cab sl done 8500 hours. Really good condition but a couple of things.

    The clutch of late seems very slow having let off the foot pedal. I have calibrated her over the years is that all you can do? It seems to be lacking a bit of bite so is there anything else to do? There are no clutch plates are there so nothing to replace

    Hydraulic lift - she really struggled to lift the spud planter this year except when I shunt forward she tends to lift a little bit more. Is this a sign that the pump is on the way out or maybe the oil is a little old?

    Its increasingly difficult to get it into gear as well. Tending not to slide in so smoothly it is greased under the box pretty often.

    I plan to keep it until 14000 hours so any tips on keeping them ship shape would be good I think they won't go down in value anymore.

    Is this dual power transmission?
    Is the hitch electronic? If so ill post later how to autocalibrate it, but i would say its wear.

    Sounds like the clutch pack is on the way out. :cry: :cry:
    It could be a sticky solenoid valve though, proper investigations before sending any money.
    The forward reverse clutch is also the dual power pack on the SL.
    They tend to get sluggish and also difficult to get in gear from standstill when the pack is kaput.
    The plates inside warp and won't lie flat causing the drag, this also causes them to wear out and resist being squeezed together making the take up a bit slow.

    Calibration will help a bit along with tweaking the fill times, but really its short term.

    Dual power pack comes out of the gearbox into the bellhousing so needs split, but other than that its not a bad job.

    Hyd pump could be a bit down by the sound of things too, proper testing with a pressure gauge is the next step.
    Does it get worse when shes hot?

    If it is the pump the SL open centre tandem pump is a doddle to change, did our oldest one (11200hrs) just before Xmas .
    Non NH pump but made by same manufacturer, less than 300 plus a few O rings and a gasket.

    They are good old tractors and worth keeping going, 14000hrs is easily achievable if you look after it.

    Replaced the main fuel line from lower tank to sediment bowl with a rubber type and double jub clips. It had severely chafed on the first right angle bend under the right hand side of cab behind bulkhead.
    As I was attaching new pipe to air cleaner bracket with cable ties I happened to notice that the most rearward injector pipe is damaged due to rubbing on the air cleaner bracket (front end of bracket). Ford/NH placed a crappy piece of plastic on it to prevent this but it has rubbed through and the injector pipe is badly marked.

    Completely irrellevent to the topic - but I notice that the main gearstick with the fast slow buttons on it on the 40 series - is exactly the same as used on the compact tractors NH make today!

    Update:

    Charge pressure light started to light when i raise the hitch with engine speed below 1000 rpm, until its almost up.
    Havent worked on the tractor yet, just moved it around the yard, so (fingers crossed) i hope is not the hydraulic pump being worm (Didnt lighted when i bought it, but flashed).
    I expect to be the hydraulic pressure switch.
    Any ideas?

    Re: Ford New Holland 8340 SLE help thread

    Which light is that? Is it roughly in the middle lower row? What is the power steering like at low speed?

    Son went to hitch trailer (Auto PU hitch) today and it would not latch on. With a total lack of thought I immediately assumed the telescopic lift rod had come out of adjustment. It was working OK day before so unlikely. Hitch travelling to full height. It took a while to realise that two bolts had come out of the upper hitch mechanism where it bolts to the axle trumpet. (The bolts also secure the trumpet). They had worked out and one was still on top of the housing. Not sure why they have decided to fall out but it is obviously a point that needs to be checked.

    When the very 1st 8340's came out there was a TSB to modify the bracket bolted to the trumpet housing. In use the linkage jammed against the bracket as the PUH hook neared the ground and it could be impossible to get under the trailer eye. Only came to light when they launched this model as they only then put on 18.4-38's which caused the aggro.

    TSB showed how to remove the bracket and "modify" it with an angle grinder

    Sorry rassiel,dont mean to highjack your thread,but on the same topic ,has any 1 come across a charge pump failing,we hav a prequad one landed to repair and it has no charge pressure,a friend tells me its air locked but im not so sure.

    Re: Ford New Holland 8340 SLE help thread

    Pete, the charge pressure light is the top right one in the pic i took of the dash, power steering, and everything works right. Maybe its the hydraulic leak i got. Got to fix that soon, but got no time!

    Wildoat, should be an option, but most of the latest models (with the NH style front axle, being Ford or NH), and even the TS models i saw got this analog and digital dash (at least here in Spain). Never seen one on the Ford blue models.
    BTW notice mine doesnt got radar.

    There is some variations on the digital screen on these dashes, saw pics of some of the latest 40 series (the ones with plastic fenders) with logos on the digital screen for gear, speed, pto rpm and hitch position.
    These dashes are common here on Spain on other CNH models, saw some M, 60 series, TS... even Case MXMs, as my neighbourgh's 120 (no radar, but semi PS). I supose this screen should come standard on the tractors with semi PS gearbox but no radar, like mine.
    Shame mine doesnt show ground and pto speed, althoght the tractor got sensors for them.

    Looking for some help with my Ford 8240. Each time I switch it off and leave it for more than an hour I get an E24 message and have to recalibrate the clutces / gearbox. Once its done it works perfectly...a bit dull having to re-calibrate each time I use it...glad for some advice.

    E46 is fuse 12 blown.
    Behind the battery you will find the oil lines for oil cooling and steering. Also you will find the oil cooler bypass valve, the side cover with the solenoids.... There is some nuts around there. Move the battery and check.

    Yes.You can try loosening no.1 at the fan end and crank.Normally would be enough but if not, slacken 1 to 4 and crank until fuel is present.Without looking at my own,I think 5 and 6 are hard to get at because of the air filter.One is normally enough.Don't forget to tighten it again when she's running.

    The first time I changed the fuel filter on ours the front tank was empty and I did not shut of the tap near the filter. I had a difficult job priming up to the filter with the hand pump and resorted to pulling it through with a small hand pump designed for pulling oil out of a diptick hole.
