Another fact is that that the Serial number of the Jeep and the motor never match on DJ3A Dispatchers. To the point of sometimes not even being close. My common assumption was that at the time WILLYS was also pulling these motors off the line as needed to be used in generators, pumps, or other non jeep accessories. I had grown pretty comfortable in knowing this fact.
That is until about two weeks ago when I was reading a thread on the CJ2A forum. A gentleman there mentioned that he had a non 2A motor in his CJ2A. His motor had a 3J prefix and he posted it was out of a CJ3A
Instead of completely doubting his word I filed the informative in my head and decided to do some research. I went to the CJ3A forum and started looking at stastics. CJ3A's were of course made from 1949 until 1953. Records there of existing 3A's listed too many 3J prefix engine numbers to be a coincidence. In addition, they too had reported a unusual amount of discrepancies between the relationship between their engine numbers and their actual serial numbers. Just like we do on our Dispatchers!!!
I turned to Colin Peabody who knows more about the statistics of our DJ3A Dispatchers than I ever will. I wanted to verify what I had found and to find out if I was seeing things or assuming something completely wrong.
With his permission I'm going to add his initial response.
THANKS COLIN!!!!!wrote:With all the 3J engine numbers in the CJ3 A line, and all the 3J numbers we know are in the DJ3A Jeeps, we have to think the ties to the DJs and CJ3As is more prevalent than we thought before. I had thought (incorrectly now) that the 3J numbers were DJ3A engine numbers only. Do we now think that Willys had plenty of engines and body parts for the CJ3A series when that model was discontinued in 1953 and simply used the same designation and parts for the DJ3As in late 1955 and later? Sure looks that way!
