Y385T Short Block?

[Ed_B]

Hey All:
I think I may have fried the engine in my Farm Pro 2425, well I didn't fry it, my brother-in-law used it and it looks like the rear main went and he lost all of the oil and didn't know it.

Anyway, I see I can get a new engine for about $1800. I could rebuild it, but the parts keep adding up to more than $1800 with bearings and a crank. I don't see that there are any oversize bearings out there if I have to machine the block/crank.

I don't have the tractor engine taken apart yet to see exactly what happened. I am assuming the worst, spun bearing(s) etc.

Is there a source a source for a short block engine that anyone knows of?
I thank you all in advance for your help.

Ed.

More than a few folks have reported that the bolts that hold the bellhousing to the engine block will vibrate loose, causing oil loss such as you describe. The bad news is that you have to break the tractor just aft of the bellhousing to get at the bolt heads. But in doing so, you might discover that sealing up the oil leak may be all that's required.

Unless your BIL actually froze up the engine that is........

Hey Greg:

I am sure that the bolts working loose are what caused the seal failure there is a gap between the block and bell housing.

I am also 99% sure that the engine is seized, unless the flywheel is hanging on one of the bell housing bolts. I will know more when I break it in half. Starter won't turn it over and I tried to pull start it and all I got were skid marks in the driveway for my effort.

I will keep you all posted. I am just looking at the worst case scenario for now. Maybe I will get lucky if it is seized and it will only be seized piston(s) and not spun bearing(s).

Ed-B,the individual parts cost make a complete new engine look better and better,because it will come with just about everything including starter,injector pump,ect.We have priced out a rebuild parts list and for just a little more you can get a new engine.We keep several complete engines in stock if you decide to get one, or we have the parts once you get it tore down, I suspect that a rod or main bearing has spun and damaged the crank.

Let me know if we can help

Tommy:

Thanks a bunch. I checked your site out first for the engine. Do they make oversize main/rod bearings and rods if I can get the block line bored and the crank turned? I am speculating, but my guess would be a spun bearing too.

I would rather not buy an entire engine if I don't have to. Is there a core on the old block, etc.? I suppose I could keep the old pumps, etc for spares. No short blocks that you are aware of?
Thanks for your help thus far.

Most dealers are only going to stock OE or OE equivalent parts. Going that route for "oversize main/rod bearings and rods" would likely be difficult.

One of our first "major repairs" on a Jinma, a 2002 Agracat, was a "seized engine" We pulled the engine and once th engine was on the floor, it wasn't seized anymore! the bell housing bolts had worked loose, the tractor "settled" and the seal clamped the crankshaft tighter than anything, couldt crank with starter, couldn't pull in gear and let out the clutch, nothing.... so don't get too worried, split the tractor and pull the flywheel off and take a look. I'll bet the engine is fine.

Ed,I do have some oversized bearings not sure,I had some 10 over,25 over on mains.Since it is a sleeved engine you can rebuild with new crank,rod and main bearings ,gasket set,ect. it just gets costly.Which ever way you end up having to go we should have the parts needed.Let me know after you get it split,maybe it is just the seal binding it up,that would be good news for you

The link you posted seems to show the engine block only; no pistons, rods, camshaft, crankshaft etc.

I don't think the chinese sell "short blocks". In the past, we have taken complete new engines apart, separate head, injection system, starter, alternator, water pump flywheel, etc. and sold just the short block. But contrary that wise old sage's conclustion, the whole is much cheaper than the sum of the parts.

But once the flywheel housing is properly attached you will most likely be up and running fine. Be sure to check the number of threads engaging on the bolts. We had to put longer bolts in the agracat we fixed in 2003.
but more recent ones seemed to have long enough bolts, just needed locktite.
(someone needs to sell the chinese locktite, especially thier powersports factories).
