So I am putting a project tractor that I got cheap together and am trying to figure out if I am missing some parts. I am putting on the selective control valves(mine has 2) on and am a bit confused with the parts book. I have the line(al38184) that goes to the wheel side of the valve. Also have the line on the other side(al55494). On the next page it show the return filter and all that goes with it. My lines are different and I have no parts for that filter(the bracket or filter head). Did some tractors not have it, or am I just missing parts. Mine is a cab tractor late sn758434. I am in Wyoming so parts or tractors are hard to find. Thanks
 
Al38184 is oil return from SCV to RH side of rockshaft housing, AL55494 is the pressure line that attaches to rear of pressure control valve to RH side of scv. Routing oil to hyd filter housing was an option that a smaller % of tractor had from factory. Both type returns could be used on the same tractor. SCV returning oil to hyd filter is preferred if an orbit motor or FEL is controlled by SCV

A John Deere 2555 is a very handy tractor, should be fairly easy to work on and easy to find parts.

So far I have been able to order most of what I need. It is 100mi to the nearest Jd dealership. Any used tractor is worth a lot more here than in the Midwest. Thankfully we don't have much rust either. The only part I have not found is the pipe for the air cleaner from the front to the back by the turbo. But a 3" hose will work.
