Ford 730 Loader on Ford 3600

[ManaFarmandForge]

I am purchasing a Ford 730 for my Ford 3600 Tractor. The loader is coming off of a Ford 3000 but from my research this should work. My question for the amazing people on here that always point me in the right direction is how do I hook up the hydraulic pump to the front PTO? the seller sent me a pic of the hydraulic pump and the sprocket that comes out of it. Will I have to take the front grill off to attach the sprocket? Ive attached pictures of the loader. I can upload pictures of my tractor if needed. Will I need any sort of special adapters to attach it to my tractor? Is this an easy install or will the radiator need to come out? Any pointers would be appreciated or if there are any tools I might need!

You will need a coupling that bolts to the crankshaft pulley on the engine and connects to the pump shaft. He may include all this with the loader you are purchasing. If not look at his tractor to identify the parts you will need. The lower panel on the front (lower grill) may need to be cut for the pump shaft connection. Hand tools are all you will need. The coupling and shaft will be a tight fit and removal and reinstallation of fan blade and fan shroud may be required to get to the crankshaft pulley. Be sure to clean the bolt holes in the pulley and use the correct bolts for the connection.

I messaged the seller and he confirmed he has already taken the pump shaft and coupling off of his tractor and is selling it to me. I made sure the seller knew that I wanted to inspect his tractor and see how he installed and take some notes so I can get it installed. This is my first time doing something like this so want to make sure I am ready. Hate projects that I start and find I have to order a part half way through and need to undo all the work I previously did.

Do yourself a favor and replace the fan belt BEFORE you put the loader on. The shaft makes it hard to replace later.

Has the splined shaft and couples... ford sold a long shaft and a short shaft, so keep that in mind if replacing. I would inspect them for wear and replace if needed as these would eventually strip out after 3500 hours or so... as least on the couple that I had.

The loader is in immaculate condition. Everything is clean and he showed me videos of it running on his tractor and we spent about an hour and a half going over how to hook the loader up what modifications to my tractor are needed how much work its going to take and answering all my questions before we loaded it up on my trailer. Though now that I am home I cut off a section of my front grill to access the Front PTO and found a problem. The Splined PTO shaft for the hydraulic pump is 13 splined. and my tractor front PTO is 6 splined. I am not sure what Old Ford Mechanic was talking about for the crank shaft pully because it looks like it just slides right into the front PTO hole but it is 6 splined. the shaft is about 10 inches long and has the coupler with the female attachment for the external hydraulic pump that is 13 splined as well. Am I counting the splines wrong? All I can find in the parts section is a 6/23 spline PTO Crankshaft. it is 12 inches long and I can probobly make that work but am curious if I need that shaft or if I need an adapter of some sort?

6 spline is 6 protrusions and 6 detents.....like the PTO shaft. I had a '63 4000 with a tube type FEL. The hyd fluid was contained in the loader pipes. The pump was attached to the front end of the Crankshaft...splined. The pump must have been in addition to the front pulley on the CS as I sold the loader and just removed the pump from the CS, no big deal as I recall, don't recall having to mess with the front water pump/gen pulley....been 30 years....things get vague.

On second thought, It may have bolted to the front pulley....trying to remember....I don't recall any shaft sticking out in front of the front CS. I don't remember having to do any modifications up there and as I said, don't recall anything sticking way out.
I just went out and looked at my 3600 from outside without taking anything apart: The water pump contains a cast bracket (heavy duty) looks to be part of the pulley as a unified casting to which the fan is attached. The fan is just inches away from the radiator. The radiator is solid (no hole for mounting anything) and extends below the crankshaft.

In short, I don't know where you would put a pump that was attached to the front end of the CS. Guess I'm no help.

To be clear, it's not a "PTO." You are connecting directly to the crankshaft of the engine. You are either missing an adapter that goes from the pump to the engine, or you need to change the adapter that's bolted to the crankshaft pulley now, to the one from the seller's tractor.

Please provide a picture of what you see and maybe we can better point out what you need to do.

IIRC.. its is the same spider that bolts to the front of the crankshaft as the two that connect to the pump/shaft in front... but its been 30 years or more?? There are 4holes in the front pulley that the spider bolts to.

I took some pictures. the front of the tractor has a hole in the front that goes back about 10 inches and there is a female 6 spline. where as the shaft of the hydraulic pump and the bar with splines on it that should go into the hole being 13 spline. The hydraulic pump is also 13 spline. I couldnt get a good lighted picture of the front of the tractor hole so its the dark picture with the female 6 spline. This hole is bottom middle of the front of the tractor.

I found this on Yesterday Tractors parts listing under PTO but its 23 spline not 13.

If I go onto the 730 page for parts I can find the the 13 spline hydraulic pump drive. though on that page there are no adapters or pump drives that are 13 spline to 6 spline.

ok, finding my original parts book.. there are 3 or more kits for various tractors, BUT..19-523 is the "kit" for a 3600/3000 calling for....
"7701044" shaft, pump drive 11 5/8 long splined both ends,
"c5nn-n879-a" 2 each, one on each end of the shaft coupler sub kit includes....
1 ea 290420 Coupler
4 ea 290422 rubber drive blocks
4 ea bolt 7/16-14 x1.1/2
4 ea washer, 7/16 lock washer "
"291315" coupler (used at pump)
and "290465" washers as needed to shim slack out of the drive as needed.. washers are 29/64 dia (thats the total description)


and there are/were different parts/kits for
2120,2140, 2130 tractors or
3400/335 tractors or
4400/515 tractors or
3500/420/3550 tractors

Note that these other kits:
may have one coupler welded on to one end of the shaft and or
different size and/or various length shafts


looking up c5nnn879a, 2912134, and 771044, descriptions seem to show that all are 13 splines including at the pump, so one would wonder it you have the correct pump or a different pump. And other couplers may or may not work,,, However all of orig parts seem to be readily available for purchase.

The pump is 13 spline. everything that I am finding online is 13 spline as well for the pump. There is a guy down the road who has a yard full of tractors and construction equipment. I stopped by and he talked to me for a couple hours and showed me all his old hydaulic pumps and they are all 13 spline as well. He mentioned the Crankshaft pulley mount and I am wondering if I am going about this wrong. when I look down the hole its 6 spline. But maybe I need to replace the part that is attached to the crankshaft pulley? How would I access that part of the tractor? I was poking around a little and I dont see an easy way to get to it without removing most of the top. The guy I was talking to mentioned that in the past he has made adapters for all kind of drive shafts using couplers. He gave me a Surplus center book with a 6t coupler and a 13t coupler and recommended buying those and a short 6 spline shaft and having a fabrication shop in town to make the shaft for me. Issue with that is it would increase the length of the shaft so it may need to be cut and re-welded to length. At that point I could just pay a machine shop to make me the 13 spline to 6 spline adapter.

I found where the crank shaft pulley is located and on the 3600 there is a belt guard that I can take off and that grants me easy access to it. Attached is a picture of the 6T spline attached to the crank shaft pulley. its been bugging the hell out of me why this is so weird and decided to look through the service records of the tractor and found they used a front sweeper on the tractor. Hence why there is already an coupling on the crankshaft pulley. I will be ordering the correct 13T spline coupling and attaching it to the tractor. I'm not going to be replacing the belt just yet as it was replaced in 2020. I have ordered the Ford 730 Hydraulic Pump Hub part C5NNN879A and will install it once it arrives. Then Ill attach the frame and then the loader. Looking over the previous replies and Barnyard Engineering pointed out the problem right away. Also thank you sotxbill for the detailed parts numbers. that helped me figure out which part I needed to order.

Thank you everyone for the help! Ill post an update once I have the loader fully on the 3600. The fun part is going to see if I can have both the canopy and loader attached to the back axle.

Bill. I think it was really thoughtful of you to go to this much trouble to help a fellow member of this fine site.

On where to get the parts, All States Ag. Parts is a pretty big outfit across the countery and very possibly they have a junk 3600 with all the parts you need for the adaption.
