Hydraulic problems

[Markdenston]

Help please! I’ve a fault on a p35.12k looks like no hydraulic pressure to the valve block for the loading legs and body tilt? Anybody know where the pressure comes from and is it electronically controlled? Thanks

If I'm not mistaken that model number is a Merlo! So you all know were you can stick that POS

Not a clue Sorry OP not very helpful I know

Yes it will have a solenoid valve that stops operations when boom is above can height. The switch is mounted on the back of the boom near the main pivot pin. Check the switch internals and power supply

Thanks for the reply I’ve checked the switch and wiring and all seems good? Do you know if it takes a feed off the valve block for pressure or has a separate solenoid on the pump?

I believe it is fed from the transmission pilot system. Does it drive correctly? There is a solenoid and valve separate to other hydraulics. Will pm you

Yeah drives spot on all the other functions work correctly off the main valve block ie lift lower boom and bucket just no pressure for separate valve that works the extra pads for extra stability!
