5000 turbo oil lines

Good evening, I just bought Airesearch turbo and manifold for a 7600 to put on my 5200. I dont have the oil feed and oil return lines to and from the engine block. Has anyone made their own lines and connections? I saw on the CNH parts page the lines and elbows to connect but they were $$$ in my opinion.

Thanks Heagon
 
Even if you bought CNH parts, they wouldn't bolt on because you don't have the correct ports in the block to hook them up to.

Best bet for the pressure line is to make up a suitable length of braided hose and tap into an existing pressure port on the block. Avoid the two near the oil pump drive hump because that is unfiltered oil.

For the return, I'd remove the hydraulic pump cover on the back of the engine and make a plate to go in its place with a suitable drain hose connected to it. I'm pretty sure that's how M&W did it with their turbo kits.
 
Back in the day before all the blocks were drilled the same turbo or not, M&W had a plate that took pressure oil off the oil pump drive plate and dump the return where the gear sits. Ive made a few out of aluminum.

I almost did it like that on our 5200, but the 7600 manifold put the exhaust forward and I didnt want to cut another hole in the hood. So I used it on a 6600 to turbo it.

If it were mine I would use a 7000 manifold and fab up the exhaust parts to come out the factory location.

Thanks for all the information. Were some 5000 blocks drilled for the turbo lines? It looks like my was from the factory. And someone before be had a turbo on it, and cut the hood for the exhaust to exit in front.

did you check the block numbers,,, to see if it had been replaced with a newer model?

Hopefully those taps will work. My 5200 with the m/w setup used the rear of the cam shaft as said by others for the oil feed. It also ran it through an external m/w oil filter then feed the turbo. The external oil filter was probably more for cooling than filtering??

I have checked the block numbers with those on the underside of the hood and they matched up. So these taps, will it be supplying unfiltered oil??
 
Looks like you have a later block in your tractor. What's the casting number on it? Look on the RH side. It will say "xxxx
6015 x".

That said, those two ports shown in your pic will work for a turbo. The smaller upper one is pressurized and filtered oil. The
lower larger one is block drain. Look at any pic of a 7600/7700 and you'll see both of them in use.
 
Looks like it already has the 7600 manifold on it.
Neither our 5200 or 6600 have those spots drilled and tapped.
Its either a later block (maybe replacement), from a turbo application originally or someone drilled and tapped them.
 
The "D1NN" is what I was looking for. This means early 1970s. Which means it's very likely original to your tractor. The earlier 5000 blocks were not drilled and tapped for a turbo. Your block however is "7000 ready".
 
Thanks everyone for the replies! The tractor has been mismatched a little bit over the years, I think someone put a turbo on it in the early 80s and took it to tractor pulls, and rebadged it a 7000. I received a lot of good information from this thread!
 
Those holes were not drilled and tapped after it left the factory. You can clearly see the cast-in boss for the lower larger
plug. Given the date code, it's clearly a "7000 capable" block. I suspect that after the 7000 came out, that all 5000s and
7000s used the same block, since there really is no difference between them with the exception of the aforementioned plugs.
The fact that your 6600 does not have the plugs tells me that there were in fact different blocks in the "x600/x700" era.
 

more confusion.. I see the early 5000 series power steering pump on it?????? So that would indicate it was with an early block?

The OP said that he has a 5200, not an ag chassis 5000 (5100). I believe the 5200 used that style power steering pump for the entire production run. It was only the ag chassis 5000 (5100) that changed p/s pump styles partway through the run. At least that's what the parts diagrams say.

yes... your right..the 7200 in the yard has the early pump also...

brain fart.
 

I'd say that block was drilled and taped later to add a turbo, the 7000 blocks were also drilled and taped for a engine oil cooler and that one isn't, I can see the pad for the oil cooler fitting behind the ps pump and it's not drilled.
My 74 5000 has a D1NN block with the pads but none are drilled, I have a M&W turbo kit for it and will use it's plumbing that replaces the hyd pump cover.
My 76 6600 has a D4NN block with the pads but none are drilled, it'll go to a machine shop to be drilled and taped for the 7600 turbo I have for it.
My 90 6610's block is drilled for the oil cooler but not for a turbo, no present plans to add a turbo to that one yet.

That's a interesting location for the oil sending unit.

I thought it was an interesting place too, I assume it is sufficient??
 

Well that location is getting feed straight from the pump before the filter, the standard location which is near the back of the ps pump is after the oil filter and a couple of main bearing feeds.
Just my opinion but I'd think the standard location could give a earlier warning of a pressure issue.
