I will send you a few pictures later on today but i know that there's one feed and two returns

It's an Akon valve chest. Pic shown

Am anxiously waiting for someone to show what pipe goes where.

I could do with knowing very soon. It's on a McCormick CX 75 by the way.

Oop's I was distracted and didn't get the picture but will definitely get it done tomorrow.

Thanks

Thanks

1 and 3 are returning oil. 2 is feeding a constant supply, 1 seems to be returning oil from where the original supply line is feeding from. 3 is going somewhere back in the backend, and I will take a few more pictures in daylight. Excuse the numbering system not in sequence [emoji87][emoji87]

Thank you Gerard for the pics. I'm a bit confused with the pipes. What model tractor is that taken from?

I've got a cx90 piped up. I could get some pictures if you want. Think my loader was factory fitted or dealer fitted

I thought I had it mostly figured out but I could be wrong. This is the way I thought it should be :
Pipe 1 Pressure pipe from top of spool valve to P (bottom left on chest valve (CV))
Current pipe needs removal from spool valve to large suction tube (steering pump side)
Pipe 2 Return pipe from back of tractor (a steel pipe behind the couplers) to T1 (bottom right on CV)
A blank on the steel pipe needs removal (32mm head)
Pipe 3 "Tank" pipe from suction tube to T2 on right side mid way up on CV. I think this then becomes the high pressure carry over.
Would this be the way it should be?

As in @gmc541 photos no 2 is supply and usually marked with a P, no1 is carry over. On a open centre system you need to break into the tractor circuit and feed the block to no2 and then carry the feed on back to wherever you broke the circuit to feed the next item in line. Usually on tractors hydraulic pump will feed trailer brake valve as a priority, then the spool valves then the hydraulic lift. They’re all part of a circuit. You just fit the loader valve inbetween one of them if it makes sense. No 3 pipe usually marked T is a return to tank from the loader valve block PRV when a service is dead ended or overloaded.

That looks so simple. Is that a two pipe system then?

 

[Numick]

Thanks Mur Huwcun. Maybe I have the pipes correct but wrong in my thinking re the return to tank. Then T1 is return to tank, not T2 ?
