FX24D Not running

[mrrooj]

I guess that plate is my only access to the underside of the engine. what looks like where the oil pan should be is bolted to frame, i would have to remove the loader belly piece, the front axle brace to even be able to undo the bolts to the underside of the motor. According to the service manual that small plate sized opening is the "pan" im guessing i need to remove the block from the frame, not sure where to begin with that. looks like some bolts from the frame go into the side of the block, i dont know how it connects to the flywheel, or if the flywheel stays with the motor. hydraulic pump and hoses need to be situated. fuel and injector pump.. hmm.. any suggestions on how to work on the connecting rod bearings on this tractor?

The drive shaft is still in the way along with oil uptake, maybe i can figure out a way to remove the uptake to inspect the bearings? the oil plate is maybe 6"x9" so not much in terms of elbow room.

Most tractors, not sure about an FX yanmar, the motor block is attached to the transmission making them a single unit. To remove the block from the transmission is call splitting the tractor in half.
This is a serious under taking. The separated ‘halves’ must both be supported where split.
This is why I say pull the oil pan. Again I do not know the FX, but this is usually doable on most tractors, but can be very involved—worse on subcompacts and compacts such as the FX.

I don't know anything for certain but I would think the small plate should give you enough access if you remove the drive shaft. Your oil strainer is held by two bolts.

Got the drive shaft off, retrieved all of the ball bearings :laughing:

Reassess how much room i had to work with it out of the way. not nearly enough.

So planning on splitting the tractor and then figuring out how im going to remove the engine block from the frame.

So far ive..

removed the dashboard, fuel tank, firewall, starter (again), disconnected: power steering lines, all the rest of the hydraulic lines that are between the front and the back, and steering wheel link.

I removed/slacked the 8ish bolts on the flywheel and then realized that my loader belly piece is holding the front and rear of the tractor together.

I think thats the last bit holding the two sides together. Going to figure out a safe way to support the two sides safely and roll them apart.

after its split it looks like there are 8 frame bolts on each side of the block holding it to the frames sides. Plan is to get a hoist to support the block, undo those 16 bolts and lower the frame to ground and then put the engine on a stand so i can flip it over and take the belly off and inspect the connecting rods.

Cleaned up and ready to split:

mrrooj, WEDGE the front axle(both sides) to prevent the engine from flopping to one side when you get everything else disconnected

Engine sump: is a load carrying part, ie HEAVY.

Got it, thanks!

Now I need to figure out a way to support the motor while removing the side frame bolts. Guessing a hoist would be a good idea.

Chain hoist or if you have an adjustable height engine stand or can adjust the height of the motor/front frame are your best bets in my opinion.

Good idea, got an engine stand from harbor freight, thinking I can jack up the engine and get it mount up. Pulled off the clutch and flywheel. But it looks like I need to remove this plate in order to remove the oil sump. Bolts are out but not sure how it's still held on. I'll keep at it when I have more light tomorrow.

Also misunderstood the difference between inches pounds vs foot pounds, ended up with the larger torque wrench.
