I dont know much myself about the 920 tractors, but have never heard good things about them. Sorry to hear about the trouble you are having. I know Pulltilbroke on this site has a couple of them, maybe you could see if he has any leads on parts?

These Lombardinis do smoke a little, its just the nature of the beast.

I have yet to find a good parts source.I've never really needed any hard parts yet. I have gotten filters and the Like from a Local Small engine outdoor power store but you got to have the part numbers.

BTW Kohler now owns Lombardini.

I'll see what I can come up with parts wise and keep you posted.

I also have the parts manual and service manual in PDF form if your interested, PM me your email and I'll dig em up and send em your way.

Search a little, they are an industrial engine, and are fairly popular. My AC dealer could get me any parts I needed, although I saved about $400 on a starter, by looking online. The fuel injection system is Bosch, and I have a Bosch dealer very close who could get me parts for that.
Here's one; http://www.powertechengines.com/Lombardini.html
The white smoke might be low compression, do a compression test.
Cold, they will smoke, when it warms up it should pretty much clear up.
One more thing,
on the moparguy thing, pulltilbroke and I are also.

This is where I found a starter; http://fleetalternatorstarter.com/
New, updated, gear reduction, and less than half the price of the dealer one. It never started so easy.

I think a gasket set and a set of rings my be my best bet if I can find them I should be ok I can make a valve guide in the shop the valve on the front cylinder moves around about a 1/16th of an inch but the rest r.tight as new well I need valve seals but I might have something in my boxes of parts from other stuff still rebuilding my powerking to busy me lol

I remember reading someplace someone used pistons and/or rings from a diesel nissan or something I'll see if I can find it.

Okay.....
I found the part number for rings.
SEALED POWER E594KC
They're actually for a Mazda, I found it on another tractor forum.
Another snippet.
gasket set from http://www.m-and-d.com/

If I had it to do over, I would probably get my parts from Blue Ridge Diesel ( http://www.blueridgediesel.com/ ). Parts guy is Elton Wright. The kit that I got from M&D had the wrong seals for the push rod tubes. If I did it again, I would buy the seals that I needed and not the kit since I didn't need lots of the seals. Besides replacing the oil pan seal, I didn't mess with anything below the cylinder jugs since I have not leaks on the front or back of the crank shaft.
...

Here's a link that helped me : http://freemansgarage.com/blog/?p=272
Hope that helps.
The one more thing is you get rings for a 4 cylinder engine so you have an extra set in future if you need it. :trink39:

New valve guides and new rings fixed the smoking issue now just got to get it to charge and fix the rough idle and surging seems like a timing issue the copper washers wasnt in my pump I had o rings that I replaced and the fuel leak stopped lot more power than before but still think it needs something to make it right has to be the timing the bore is 86mm I got the measurements on the rings if anybody needs them bout 30 bucks shipping and all for 2 sets from hastings

:howdy:Just figured i would chime in.....Thats a nice 920, i have a 7790 in my fleet, with a 46 inch snow plow, and mower deck, and i love it! I too have had a hard time finding parts, mine smokes just like all the other ones that i have read about. I just finished restoring my cub cadet 782d, diesel, and have to pick another one to do. I already did 2 cub restorations, maybe the 7790 will be next, atleast a paint job anyway!!Brett in the pocono's
