430 engine identification

Anonymous-0 · Jul 23, 2011

i am having one hell of a time getting the correct engine gaskets for my 430. and the dealer is of no help. the gasket set that they sent me was suppose to be the correct one but the head and pan gasket are about 3 inches too short. the only head gasket that seems correct is for a desil but mine is gas . the bore appears to be approx. 3.8 . the number on the plate on the block is 2024786 , the plate on the dash is case 4308241704 and the cylinder head is g2084. The shop that did the crank tells me that the crank and rod numbers that i have are for a 188c.i. deisel. i have been messing around for 3 weeks now with no luck and to the best of my knowledge it is the original engine but i,m not positive .. help.. sam

I just googled G2084 and came up with a head for a 580B of 630

Should say 580B OR 630. Maybe it had an engine transplant? Does the sheet metal look original? The Gas 148(which is what a 430 would come with) is shorter than the Diesel 188 but just a few inches. Maybe the gas 630 engine is the same length as the D188

the sheet metal appears 100% original on one of my google searches i did find a notation that the 430 could be had with a 148, a 159 or a 188c.i. engine but that is all that i could find sam

For gas engines 430 would have been 148, 530 would have been 159, and 630 would have been 188CI. I went to tractor data dot com and a gas 630(640) is listed with 188ci gas engine, bore 3.8125. I think someone put a gas 188 from a 630 in what was most likely a diesel 430. I think the gas hood is shorter than the diesel hood, so most likley it was a diesel. The dash plate should also say 430,431,440,441 or some such. That might tell what it used to be. I think you have a 630 gas engine.

I have a 148 gas in a 430 and could use some more ponies on occasion, so I have been sniffing around on transplant options but have no real expertise. DW

i am sure now that you are correct and that the tractor at one point did have a transplant from a 630. i have finally got it together and was wondering if anyone had the valve setting for a 630 188 c.i. gas thank you sam

All the specs i have seen call for .014 at operating temperature. Just curious, Diesel 430's had a water trap at the very lowest part of the fuel tank.(not just the sediment bowl but something made into the metal bottom of the tank)Does your tank have a water trap?

yes there is what appears to be a water collector at the bottom of the fuel tank. on an added querey i now have the engine started but appear to have low oil pressure and no oil to the rockers. i did crank the engie over without the plugs before starting and the oil shot across the shop' any ideas and how are the rockers oiled sam
