Its been a while. This tractor is a diesel and has a 5 speed single clutch. To swap it to a gas engine what do I need to change? Just the clutch and flywheel?
 

Gas flywheel, throttle linkage, gas fan blade, air cleaner and piping, may need to swap battery boxes, diesel fuel tank has a return fitting that will need plugged or get a tank for a gas tractor.

The 4 cylinder diesel engines made then are not as popular as the 65/up diesels are, but whats wrong with your diesel that makes you want to swap it out.

And a gas engine, ignition and wiring, manifold, carb, linkage etc. of course.
 
I think it got water in through the exhaust manifold, its wont budge, even pulling it. Brass in the oil pan also. I think whoever put the balancer on didnt time it right. I always wondered why it vibrated a lot but didnt know when I was young until I started rebuilding them myself. The tractor is all ready for the engine to be pulled but its not good to let things sit too long so I thought I would do a swap until I get to the motor.
 
I couldnt remember if you need to just mainly swap engine for engine or do you change input shaft also. I have a gas tractor that Im taking the engine off of.
 
O Yea! I forgot about those minor parts! :lol:

Glad to see you took that as humorous, since it was mean to be! :)

RRR says he has a donor tractor, so he should have all he needs, no?
 
I don't work on the 4 cyl Fords much but helped a friend put a diesel in a gasser.
It seems I remember he had to change the fuel tank mounts as they were different.
 
I still need to know if its just separate from the tranny forward and bolt the gasser one up with no input shaft change?
 
That's right the diesel head is wider. The gas flywheel bolts and works on the diesel.

(quoted from post at 22:11:41 07/15/18) Use the block plate that came with
transmission. They changed thickness
somewhere in there.

as UltraDog says, and
The hydraulic manifold under the pump must stay with its matching block plate.
Most online vendors say piston pump hydraulic manifolds 310878 and NCA933J
are the same.....they aren't.
One is for the thick plate, the other is for the thinner plate.
Generally..
NCA933J -Hundred series with thick plate.
310878 -Later 01 series with thin plate.
 
They are both thin plates. While were on flywheels, I know the diesel has less horses than a gasser but I've used both on a shredder and the diesel didnt bog down like the gasser would in thick grass. Was there any reason Ford used a thinner flywheel on the gas models? That heavy flywheel carries a lot of force with it.
 
This tractor is a diesel and has a 5 speed single clutch.

I thought that they dropped the single clutch (non-live PTO) on the 5 speed when they came out with the 4 cylinder 2000/4000 series.
