Al: Basic chassis and power train never changed. Two basic changes from 100 and 130 were fan hub automitive type water pump, versus the old pump on bottom water outlet from block, and pressed steel front wheels on 140. The 140 started off 58 to mid 63 with 40-60 type grill, chrome plated decals, 6 volt generator. Mid 63 until 67 it was 04-06 grill which stayed until end of production in 79. The decals went back to adhesive type after mid 63 and that stayed until 79. Between 58 and 67 they were called either Farmall or International the later being industrial, and the name McCormick remained in decal. From 68 onward they were all called Internationals, with the word Farmall on model decal just above 140. Not sure if anything but 140 appeared if it was industrial. The name Mccormick disappeared from decals at the end of 67. 12 volt generator came in the latter half of the 60s and 12 volt alternator somewhere between 72 and 75. Key start came with the alternator. There are bound to be items I forgot, but that is close. One other item, all 140 have a heavy wire in harness, most of them, it's not coupled at either end. It was for an optional horn positioned between radiator and grill. I found this wire when restoring my 140 and changing it to 12 volt alternator. I couldn't imagine what such a heavy wire was for ( probably 8-10 gauge). After much digging in IH literature I discovered what it was for. I now have a switch on dash and use that wire to power a 12 volt motor on an attachment I have on front of tractor.
