jcb 526 56 air seat

[bobk]

Ok so some little scrote has emptyed the air out of the seat , presumably by pulling the knob under the front , do they inflate by pushing the knob in ?
This method isn't working

 

[David.]

More usual to lift the lever/knob to raise air seats.
A picture would give us a clue..

My seat in our New Holland started leaking, would need pumping up constantly.....then compressor gave up!
Shoved a old duvet under the seat. Spends most of the year either attached to Sprayer or drill so hasn't been too uncomfortable. However had to spend 2 days on grain cart with it, turns out its no so comfortable bouncing about the lanes

New seat ready to go in.
Tho I will miss my cozy naps in the corner of fields

I don't think that's the right knob?

Isn't that the suspension travel height limit adjuster knob on the KAB seats? Any other knobs on there? Unless it's a different model of kab seat than I normally see in handlers?

Oh , you could be right , can't see any other way
Normally a lever at the side , have you got a diagram

There’s another switch/toggle thingy higher up. Grey in colour from memory. Good chance a wire has rubbed through or been ponched if the seat has been right down. Killer for air seats is to have them to low or run out of air

Same as my 526
Just check that the black rubber cover isn’t stopping the plunger on switch going fully in.
It’s surprising how hard you need to push mine for the compressor to activate.
I can’t remember if you need ignition on or not for it to work but I like to inflate mine when engine is running

Fart into it

Yes that the correct knob for seat height, push in hard to activate pump.

Usually the wires inside the seat base will be broken or cut by the mechanism.

Check there is power to the plug behind it first, if there is then take the seat out and lift it's skirt and have a look inside.

Seat comes out very easily.

No i'm not, i was thinking of another version both pictured below. So yes i guess pull out to let air out and push in to pump up. Best check out the power supply to it, i wouldnt waste too much effort in trying to fix the actual base though unless its an easy fix since a new base is quite cheap anyways. you probably have something like a 15/E6 Seat.

Ok , so there's power to the switch , if I join the power in to the power out and bypass the switch is the alright
If it works then the switch is shot

 

[bobk]

Sorted , bust wire behind the seat , first job take seat out

Airbag went on ours. Modified.

Piece of wood does the trick.
