Replacing a mini-excavator seat

[Phlebas]

Attempting to replace the standard seat in my Volvo EC18D mini-excavator with something more comfotable. It looks as if the existing seat runs on two tracks attached to the seat baseplate. So replacement should involve releasing the existing seat from the rails, sliding it out, and replacing it with a seat which fits the same rails. My main problem is the cab of the EC18d is very small so its difficult to see what needs to be unbolted and how to get to those fixings. Has anyone done this?

Undo 2 front bolts, slide seat fwd, fold back of seat fwd and take out the back 2 bolts. Simple

Thanks for responding to my query. Please look at the enclosed pics. Is it the Allen head bolt going up into the seat from that needs to be removed at each of the four corners? The seat has a back tilt adjustment but it does not appear to fold.

There is no way to access that nut as it is inside the channel so no space for a socket or spanner.

I’m pretty sure if you slide the seat forward you can get to the Allen bolts on the front and if you slide it back you can reach over the back and get to the ones on the back, then the seat will come off and you can then remove the bolts.

Well, unless they built the cab around the seat or got a midget to go underneath, there has to be a way.
The seat in my skid has the rails but unbolts from underneath to access the rail bolts.

They come out, I've replaced the seats in jd50, Volvo 60s , Kubota kx121, dynapac rollers they all unbolt the same.

Might be a stop plate you have to remove in order to allow the seat to slide further and allow access to the bolts.
