Dan Hiebert Posted January 5, 2011 Report Posted January 5, 2011 Greetings all. I need to replace the steering sector shaft on my 48 D-24. Couple of places I've found that list the part don't have any, and won't get any. The only ones I've found on e-Bay are for a 41. All other associated parts for "48" begin at 42. Part number listed is 866809 for the 41. Can anyone tell me if this will fit the 48, and if not what the part number for the 48 steering sector shaft is? I haven't finished looking, and the correct part number should help immensly. Thanks in advance. Quote

Part number listed is 866809 for the 41. Part #'s can be tricky.... Although part #866809 is listed as 1941 Dodge D19. Part #867534 is also listed for 1941 Dodge D19 (US body, Windsor built) which is different. In some cases there is a denotation of S/A which simply means "same as" and is interchangeable. However in some cases two different part #'s are just that TWO different parts. I have had difficulties in the same situation. Sometimes exact measurement trumps part #. Will look in my Dodge books later if no one steps up with the correct #. Edited January 6, 2011 by Roadkingcoupe Quote

Hope that helps on your search! Quote

Hope that helps on your search! The more info I have, the easier it will be. I imagine theories abound for just why the same part will have several numbers. Thanks for the additional numbers! Quote
TodFitch Posted January 6, 2011 Report Posted January 6, 2011 The more info I have, the easier it will be. I imagine theories abound for just why the same part will have several numbers. Thanks for the additional numbers! Near as I can tell from looking at parts books from the 20s, 30s, 40s and then 80s & 90s, Chrysler used a simple sequential numbering scheme for parts. Assume Joe Engineer is designing a widget and his preliminary guess is that in addition to using some already available fasteners, he'll need five new parts to make the widget. So he goes to drawing control and gets a group of six sequential numbers assigned (one for the widget plus five for the little pieces that go into it). Now Sam comes into drawing control and gets some part numbers assigned. Later Joe comes back because in needs two more part numbers for his widget design and gets two more numbers but they are not consecutive with his previous numbers because Sam got those. That type of operation is very similar to what they did at a manufacturing plant I worked at decades ago and is the only reasonable one I've been able to come up with based on the patterns I've seen in the parts books. Net result: The smaller the number, the earlier the part was designed. You can get a pretty good idea of the first year of use of a given part in the 1930s based on the number alone. You may not have a clue what the part is or what make car it goes on. But you can guess the year pretty closely. So, the lowest number part for an application is the original one. The higher numbered parts superseded it. Why supersede a part? They figured out a better or cheaper design. Since it was not the same part (maybe a different material or even just a heat treatment specification) it needs a new number. And since the new part is just as good as the old for the vehicles in the field, why keep making the old part? Just issue a "superseded by" listing for the old part giving the new one. Rinse, repeat for as many numbers/parts as needed. Quote
Roadkingcoupe Posted January 6, 2011 Report Posted January 6, 2011 So, the lowest number part for an application is the original one. The higher numbered parts superseded it. Looking at a part number can tell a lot about the application before even looking it up in the book. There are trends rather then rules about part #'s. An example is the even odd scenario. If a tail light housing is an odd # it is for the left side (drivers) if the part # is even it is for the right side (passenger). This occurs 70-80% of the time but is not a rule with MoPar parts.

This occurs 70-80% of the time but is not a rule with MoPar parts. I can well imagine that the left and right tail lights were designed at the same time by the same engineer. So it would not surprise me if they had consecutive numbers. Looking at Group 18, you can see when some one came in and added a whole lot of "missing" fasteners by the sequential numbers. Or you can look at the first year of a component and see that the internal part numbers are often pretty close to the overall component number. But later years that use that component might have no apparent correlation between the numbers of the internal parts and the assembly if it reused internal parts from the earlier design. Regarding the lower number being oldest, I was referring to the situation where several parts are listed as equivalent, like the "part #1317461 S/A #817241 S/A #953769" set posted earlier. In that case I would assume that 817241 was the first designed, was superseded by 953769 which was superseded by 1317461. Quote
Dan Hiebert Posted January 7, 2011 Author Report Posted January 7, 2011 I imagine minute changes in parts prompting PN changes is good for the manufacturer to track down problem areas - but it sure doesn't make it easy for us consumers to find the right number. I was successful in finding a sector shaft, thanks to the help from this forum. For all intents and purposes, there were only two available nationwide (other than salvage). Of course, if I continue to look I'll probably either find one cheaper, or find a whole serviceable steering box that is cheaper as well - that's usually the nature of things. BUT, at least it won't be so exciting keeping the ol' Dodge between the ditches Quote
