    Re: Transmission pressure light.

    Yes that is correct with the loader. Load sensing line brings the pump out of standbys mode so to speak.....when the joystick is moved.

    One of the spools needs an O-ring on the nipple as the...

    Cheers for the reply footsfitter
    No it's not plumbed in via QRC but hard pipes so no spool valves are taking up if that makes sense?

    I don't think I've asked where to get a seal kit on another site!?
    Also yes I was told what to "check" but I had the pump off and stripped at that stage! Also I've no means of pressure testing.

    Anyone know can you get a seal kit for the internals of the sle hydraulic pump? Or do I need one after disassembling the pump? I know I need a new mounting kit.

    Yes I will see about an o ring kit and replace all o rings and seals while it's apart. Then check the suction pipe and PTO pipe aswell while I'm there ... Then all together...

    Re: 1993 Ford 7740 sle transmission issue

    Nothing as of yet... I pulled the pump and stripped it down but everything looks in order.
    Maybe wasen't the right thing to do but now I know the pump is good. And I was pretty sure it was the pump 🤔

    Re: 1993 Ford 7740 sle transmission issue

    Yea I'd say after the 40series they changed the design! I guess I'm looking for the easy and cheaper things to check first.... Failing that it'll probably be sent away.

    Anything to watch for in...

    I changed all but the steering filter as the steering is unaffected.
    I did find shrapnel from a bearing race..... I think from the rear 4wd shaft bearing.
    I'm curious could the hydraulic pumps...

    Thanks for the Rey Footsfitter.
    That is correct, because I have the variable ccls hydraulic pump if the damper plate had failed I would have no steering. I'm really pushed on an internal leak.....

    1993 sle 7740 has no drive and no hydraulics and the transmission pressure light is on constantly. Possibly unrelated but since the tractor was parked up it's now very hard...

    For anybody facing a similar issue.... It turned out to be a blown capacitor in the ECU presumably due to the wires rubbing in the loom and shorting it out!

    I have tried that ironhead, unfortunately it was no good... The error codes on these are self reseting when the error is no longer present.

    Re: 1993 Ford 7740 sle issue(s)

    That's an interesting theory and makes alot of sense too. Either way I'd say the ECU needs to come out and get rewritten or repaired!

    Re: 1993 Ford 7740 sle issue(s)

    Up until this week the bottom LCD never displayed anything only the top part displayed gears. That's why I find it odd!
    As far as I know it's just a basic sle no frills on the rear linkage at all!...
