Hi,
May someone help me locate the hydraulic pump on a Same Silver 100.4?

Been a while since I have had one but isnt the steering pump and hydraulic pump facing away from each other? Or am I dreaming

Not dreaming, your right - steering rearward, hydraulics forward

Covered, or should I see them without removing anything?
I looked up new pump on a net store to see how they look, but couldn't see anything alike behind the fuel tank...

If your digging potatoes you wont see them until you dig all the muck out from around the diesel tank and around the 3 filters

 

[ridger]

They go on the front and back of this thing

Dont know how to draw an arrow to it but look up there and you will see the 2 pumps

Yes that's it

Has yours stopped pumping or lost pressure

Very bad pressure. And I think, from the location, that it has also started making a noise.

Try filters first or maybe you have

Mine stripped the splines off the shaft that drives it at a time

Thanks.

I'm going to replace oil and filters. But because of the noise I wanted to locate the pump to check if the noise is from it.

And by the way - one pump is for the steering and one for the rest of the hydraulics originally?
Or steering and front loader on one pump?

One pump is lower pressure for steering, agroshift, 4wd, diff lock, pto etc and other one is lift and spools

You’ll need to take the tank straps off, then you can move it out the way, you don’t have to completely remove it. It’s high up near the mud guard at the back of the tank. It’s quite covered up in pipes etc which makes it awkward to get at. You need to remove the top pipe - 3 Allen keys bolts, there is an oring as well. The lower pipe I found easier to undo at the other end near the spools. There are 4 bolts on the actual pump, 2 Allen key & 2 volt heads - you only need to undo the Allen keys. To get easier access I cut an Allen key down. It’s a faff of a job but not really hard to do
