Long 610

The long 610 is based on a Fiat design as were all the smaller long tractors

Your question about plate removal vs. oil pan makes it sound like MAYBE the oil pan is structural cast steel, which it is on various tractors. If this is the case it can be lowered, using a floor jack by removing two bolts that go through the bolster into the block and replacing them with two that are four inches longer. then remove the rest and slide the bolster back on those two long ones.

Exactly. They don't have a frame and the big cast pan is bolted to the bell housing and the front bolster.

Where's the best place to get parts? Pistons/rings and rod bearings? And a complete gasket set?
I measured the piston: just under 4". Here's what I found:
If it measures about 4 inches, that lines up well with the engine used in the Long 610 Tractor — the Fiat 8045-series 4-cylinder diesel, which has a 100 mm bore (3.94"). That’s basically right at 4", so your measurement makes sense.

I'd go to that chap I sent the link of in my previous reply. Has good knowledge of these units and a good selection of parts.

Nat i looked on ebay and there is still a fair amount of stuff at reasonable prices. I did not look at the Fiat version. also most 2610 are same as 610
