L3400/2800 Hydraulic Drawing

[bigballer]

I put together a rought sketch of my current setup. Am looking to identify the follwing lines:

1) Is this Power Beyond?
2) Return to tank - I think this is the only one I know for sure..
3) No Clue
4) No Clue

Can anyone help me ID these?

If anyone has Visio and would like a copy of this, PM me and I'll send the file over..

RE 3 and 4, the hard lines come from the middle of the tractor and into hyd block, do they come from the pump? why are there 2 of them?

 

[bigballer]

answering some of my own questions.. looks like 3 is return to tank and 4 is in from pump..

so then there are 2 returns to tank? in the kubota manual it states that #2 is from implement (Outlet), and #3 is the Tank Port. what is the difference between Outlet and Tank Port??

I was looking at some picts of mine since I'm not close to my tractor and it looked to me the they (3 & 4) are flex lines coming off the loader valve to the hydraulic block under the r/h step.
I would figure they both can't be return lines, one of em has to be pressure since the rest go to the loader cylinders.

i want to add a 3 spool open-center stack valve (with pb port) as shown in drawing. does my drawing look correct?

 

[subzero]

this would be the correct way...without any backhoe... do you have a back hoe, any other questions email me subzero@mcsnet.ca

 

[bigballer]

yes, i already have the backhoe (and ports for it) and just want to add the 3 spool..
