Peljob eb12.4

[BigPoppa]

Hello, I have a 1995 peljob eb12.4 (which was replaced by the Volvo EC14 series) at home for small DIY projects. I was slightly ambitious with a log/tree with the grab attachment on and the machine cut out.

Afterwards I had no hydraulics to the arms or slew, only tracks and blade. And the engine would only run for about 15 seconds and shut off.

After some investigation it had blown the glass fuse in the right armrest, the holder was also dropping to bits so I replaced both.
With the engine cutting out I started with the fuel filters and a tank of fresh fuel, still no good. I found there was no power to the fuel pump. I ended up rewiring the fuel pump and now it ticks over and revs well, it's a mitsubishi L3E for reference. But the cut off solenoid stopped working at the same time everything else blew, I haven't got around to it yet but to stop the engine I push the plunger on the end of it, for now.

Also, the safety in the left arm rest has been bypassed since before I owned it.

So, there is a 6 slot fuse box under the seat, and the bottom left 15 amp fuse keeps blowing. When I replace the fuse I have hydraulics on the arms and cab slew briefly, before it pops again.

I downloaded a manual for it assuming there was some kind of electrical solenoid that cuts out the hydraulics, but couldn't find one in the diagrams. Google says there is no solenoid and the hydraulics work off pilot pressure and the pump is directly driven from the flywheel.

Does anyone have any experience with these machines please? Is there a hydraulic solenoid? With maybe a burnt out coil which is blowing the fuse? I can't see anything obvious, and the manual wasn't much use.

Thanks in advance for any help, much appreciated

There will be a solinoid that cuts out the hydraulics. It will likely be on the pilot side (hence the pilot controlled items not working).

It's obviously been bypassed to be always live, but I think you are right with your deductions.

Do you have 2 speed tracking?

No, just single speed

Thanks, I've never had one or worked on before so a lot of learning to be done for me

This is under the cab behind a metal plate, I had to grind the bolts off to access. I wouldn't know where to start

main valve block ... the servo solenoid cut out valve will almost certainly be elsewhere ... can you trace the wiring back from the dead man cut out switch at the arm-rest to locate the solenoid valve ... coil is probably cooked on it, hence the fuse blowing and no servo circuit - may be under the floor plate ?

That makes sense thank you. I'm back at work now but will try on my next day's off and update. Thanks again

Had to grind all the bolts out for the floor plates, they just kept spinning with 30+ years of rust on them. But, I think I've found the culprit, it's melted!

yeh - I'd agree you've had yer money's worth out o' that one - hopefully it'll come off so you can measure the bore, length and diameter for a replacement ... if it's still there it should have a wattage embossed into the body too

Thanks will have another play on the next days off

Just another novice question, when I remove the damaged parts and undo the cable is there a chance if hydraulic oil leaking?
