I'm still working on getting that late model 430 I posted about a week ago. Question: Do the 430 and 530 gassers share the same block and crankshaft? I know the 430 is 148 ci and the 530=159, but is it just a difference in bore?

Thank you,

Glenn F.

pretty sure the 159 is longer than a 148, I do know the camshafts will interchange cnt

I guess what I really want to know is what all do the tractors share (or how do they differ) in a given year? Driveline, pto, cooling system, fenders, sheet metal, etc. I assume they're more similar than, say the H & M Farmall.

Joe Young seems to know these tractors right down to the cotter keys....

Thank you,
Glenn F.

The crankshaft part numbers are consistent between the 148 and 159 engines of the same vintage:

The early 430s and 530s parts manuals call out part number G11183 for the crank in both engines.

Late serial numbers call for part number A37210

I dont know if they are truly different or the early part number was an "assembly" number that included the crankshaft and the pilot bearing??

The blocks are the same dimension (roughly 1 1/2" shorter than the 188 diesel or the 188 gas (630)), but the part numbers are always different from early through late models:

Early
430 (148ci) - G2034 or G11911 or G10506
530 (159ci) - G2089 or G11957 or G10507

Mid
430 (148ci) - G2034, A37470, A36779
530 (159ci) - G2089, A37209, A36777

Late
430 (148ci) - A37470
530 (159ci) - A37209

One of the reasons the castings changed over time was to move the oil filter from aft of the distributor forward under the PS pump.

Camshafts show a different part number between 148 ci (G2055) and 159 ci (G2049) engines, but the cam bearing sets are the same part number so the dimension of the shaft must be the same but the lobes might shaped different??? The camshafts are consistent from early through late models.

Besides the engine, the biggest difference between the 430s and 530s (Ag models) is the tin. The hood tin is taller on a 530 (and 630) which requires 15" grill screens. The fuel tank is under the hood on a 430, while the 530 and 630's fuel tank is part of the tin work.... In other words the larger fuel tank is exposed.

Another difference is the fenders. 430s always had clam shell fenders and small footplates that were not connected to the fenders. The early 530s had full fenders that connected to the footplates similar to the 300s and x00B series tractors before them. The very late 530s and 570s were fitted with clam shell fenders similar to the 430s..

Another major difference was instrumentation. The 430s had a tach, temp gauge and two indicator lights (Gen and Oil pressure). Early 530s had cluster gauges that included Fuel level, Water Temp, Ammeter, Oil Pressure, Tach and Speedometer gauges. Later models (after serial number 8262800) had individual gauges.

The lower tin on the 430s resulted in a different placement of the hydrostatic steering valves on the later tractors. The 430's valve was placed in front of the radiator behind the grill screens, while the 530's was placed under the fuel tank aft of the engine. Of course this difference in valve placement resulted in different plumbing from the pump to the valve and then on to the steering cylinders. The early 530s had several different power steering setups before the hydrostatic steering system was introduced with serial number 8262800. The PS options for the early 430s were limited. The Char-Lynn system used on the 300B/400B was available, and there was a system available for the solid front axle utility. That being said power steering on the "economy model" 430 was not common.

Other than the items mentioned above, the drive train and chassis between the two models were identical, or nearly so....but there were a number of changes made from early to late models. - Joe

Joe I know the camshaft change is the addition of a fuel pump lobe, other than that a "VA" series through 159 are the same I have installed "VA" series cams into 159 engines if you look up a "VA" series cam they sub up to a 159 cam, that is good to know on the length as a 159 will bolt into a 148 space with no hood mods thanks cnt

Hey Tom

I thought the cams were identical as well (and they may be...), until I looked up the part numbers this afternoon. The numbers didn't change throughout the production run of the 430 and 530 according to various parts manuals, but the numbers are different between the two models. All the best - Joe

I just checked the 470/570 parts manual, and both call for the same camshaft part number G2049..... Interesting that they would be different from 1960 to 1969, and then identical for the last couple of years. That tells me they must have been identical, or nearly so, all along.... - Joe

they must have had at least two different blocks for the 159, the 955/150 swather's I have have the 159 power plant and they have fuel pumps, I do not remember if the 530 of mine has it,,covered??, when I needed a cam for my 530 some 8 years ago I was going to order one and found the new number subed all the way back to the VA models, I also have a 950 swather with a 126 (200B) power unit that also has the cam driven fuel pump but am pretty sure my 200B does not have the hole for one,, maybe a later run mod??? cnt

the early 430 and 530 will not work on the late with independent pto, the early hand clutch 430 and 530 dont have splines in the crankshaft for the pto shaft like the later 430 and 530 also the the oil filter on the older blocks will be in the way of the power steering pump

I don't know for sure on block length but I do know a camshaft from a 164 will fit a 148 because we have one in one. It is a G2003 part No. you find it has allot more duration than the original 148 camshaft. Will make a few more hp. FYI
