4600 Engine Conversion

This was mover from "Tractor Talk" to the Ford forem.
I'm really scratching my head and looking through parts books trying to decide if I can convert a 4600 gas with 8 speed with independent pto to diesel. I have several 4400 diesel engines and one 445 diesel head setting around. The gas tractor only has 2000 hrs on it and the only reason it was torn down was that rain got into the exhaust and stuck it real bad. I did get the pistons out without too much trouble and ball honed out the rust and it doesn't look too bad for a gas engine but I will rebore it for a diesel. My uncertainty is about the flywheel mainly and maybe the front pulley. The original flywheel is the lighter one with an 11" disk. I have a 66 3000 diesel 4 speed flywheel that is a lot heavier that looks like it will match up to the original pressure plate and throw out assy. but the part number is not the right one. I also have 2 4400 diesel flywheels with 13" discs but when assembled they are an inch or two thicker and both have a ring instead of fingers touching the throw out bearing. I could change the throw out brg. assy and fork and maybe it would work but I just don't know about any of the flywheels being the correct one. Also, according to the Ford parts books, the front pulley is different between gas and diesel. And a 4600 diesel is different from the 4400 diesel although they look the same. I'm pretty confident converting the engine but the clutch and pulley is my issue. I have searched this site and can find nowhere that someone has done this conversion. I have two of these gas 4600's and two 3600 diesels but they have smaller engines and different flywheels since they are both double clutches. I have a 2810 and a 3910 diesel with IPTO and maybe I could look at their flywheels if I took the starters off but they are smaller engines. Maybe leaving them gas is the smartest choice but I like diesels and I would like to try the conversion so others may know if it works. I would like to post my progress and how it works on this site but I need some expertise I'm sure is out there. Thanks and more as I progress and this is a follow up to my earlier post on (4600 Head Swap).

I converted my 4000 gas to diesel but that was back in the early 90's so memory is a little foggy, flywheels have a different part number because the starter ring comes with it and they're different. Not sure why the 4400 front pulley has a different number unless the it has bigger bolt holes for the pump drive or something like that, both the 4400 and 4600 diesels are 201's.
Personally I'd use the 4400 flywheel to get the bigger clutch or you could change the starter ring on your original flywheel and reuse it., The 4600 throw out bearing and hub should work ether way. Did recent clutch job on a 5030 the had a finger pressure plate and the replacement plate had the ring, bolted it in, adjusted the pedal and it worked fine.
Diesel pistons, head and intake, pull the distributor drive and governor then add a diesel timing gear and fuel system and you've got a diesel.
It's easier to convert the engine than it is the tractor, you'll need to pull the fuel tank and add a fuel return fitting, don't blow your self up brazing on a tank that has fuel vapors in it, I used a soldering iron. If a 4600 gas has the air cleaner thru the side of the hood back next to the tank like a 4000 you'll need to modify the intake piping to make it work or add a air filter system to the radiator shell and replace the left side hood panel with one that doesn't have the air cleaner hole. You'll also need a diesel battery tray because the gas one sticks to far forward to allow connecting the air cleaner hoses to the intake. the brackets that hold the dash panel and gas air cleaner up are different from diesel brackets but can be used.
There's a few other small things to change but that's the big items that I can think of at the moment.
