Hey all, figured I'd ask a question here about engine numbers in 1960 if anyone has any data points to draw a conclusion from about what is correct ...
I have been offered several 3J numbers but I need to know what numbers would be correct for my Surrey and dispatchers.. Originally I was just going to use a MC marked motor from an M 38 but now it seems worth it to have the right marked one..
Does anyone have a chart of the engine number range by year?

Edit.......title of the post shoulda been 1960, not 62...

Topic title changed to 1960.

Hi Bill, I'll add a little info here from notes I've gathered as Colin and I work on this DJ3A Production / Survivor Chart. I see a '60 Titled DJ3A 56337-15015, the 321st unit built of a total 1959 run of 1948 units, having Engine # 3J162503. As we all know Willys were titled when they were sold, so maybe we could figure this engine number as the lower end of the range. I also see another late '59 built unit, 56337-16476, titled as a '60, has Engine # 3J165146. That's 3643 L-134's later than the other one. Don't forget, the l-134 was available also as service part replacements and industrial applications. I don't know for sure that second engine is the original in the unit as it is 1600 engines more than the 1948 DJ3A's produced in '59, and seems high for other uses. I also see a note about Engine # 3J166252 in the 1960 neighborhood, but I didn't note where I found that number. It falls reasonably into the '59- '60 Production sequence. I have no engine number notes on 1961 or 1962 titled units, but we have a Factory Production Chart showing the first January 1963 unit was 56337-22736 Engine # 3J173851. So, in summary it looks like you should be looking in the 3J162503 to 3J166252 neighborhood. Hope I've not confused everyone with my rambling.

If anyone wants to add to this thread I'm sure I am not the only one deciding what engine number would be correct for my year jeep? Thoughts as to correct numbers for all the years of the Dispatcher and its variants would be great..

If you have an original engine in your DJ and are willing to share the numbers with us, that would be fantastic! This is the sort of group research the net really shines at, lets take advantage of it!!

EDIT.. The following are engine numbers from my jeeps. To save space I didn't list the S/N prefixes of 56337 for all jeeps listed.

1960 DJ with doors....18843 engine 3J168848 probably original....Jeep was a delivery bodied dispatcher, tub highly modified. Engine number seems a little high given above numbers.

1960 Surrey 17918 engine U84068 replacement from wagon? This is the jeep I need an engine for......and it was originally a pink Surrey, but has been painted many times and tub has some modifications I need to fix. I have located most of the rare parts and seats, need to get started on an engine. Had Toyota rear axle, but I found a DJ one for it. Serious project that is gonna take serious work. Has Overdrive from a wagon??in it too.

1960 Katrina Surrey 17509 J251355 2A motor, 1948?? Originally blue Surrey. Engine painted blue, probably a reman replacement. It is set up solid anyway thanks to the hurricane. Being preserved for posterity to use as a reference for building up the other Surrey. A few parts might wander over to the other one.

Green delivery jeep 20703 3J 170679 Probably original but jeep is NOT a 56 as it was sold to me.. December of 61?? Engine partly dismantled but looks like it has been there all its life. Was a sliding door hardtop jeep at one time. Will end up giving its frame,and drivetrain to the 59, and a tub to Alex in MO.

I also have a red 59 15933 that is engineless (any ideas?) Formerly a convertible, no tailgate jeep. Tub is really nice , original faded paint still present, frame needs some serious welding to fix modifications.

And a red 60 17052 that has a V6 and frame modifications to accomodate it. And 4WD. Jeep is rusty and heavily modified so may get built up as a trail jeep to have fun with. Has tailgate.

All the jeeps listed above have the correct frame numbers in the usual spot, so I beleive the S/N 's listed ARE correct and they are not tag swap victims.


NEXT????

I edited the above post with my numbers...anyone got more data points to add? You guys withe the database let me know if you need any other stuff from those jeeps for your files...

Hi Bill-

I am having trouble typing complete sentences into the format as the entire format area doesn't show up on my screen, so I don't know all of what I have typed! Send me an email at: colins60vette@cox.net and we can hammer out the engine number stuff.

Colin

Sounds like ya need a larger screen! Anyhow, I sent ya an email.NFord2N on aol

Colin sent me this in an email.....more numbers to peruse..

.



From my database, I put this together: 1958 DJ3A #14130, eng# 3J161176… 1959DJ3A# 15015, eng#3J162503; These two are 885 DJs apart by serial number, but 1327 engine numbers apart. 1960 DJ3A#17251, eng# 3J166252 is 2236 DJs later than the #15015 above, but the engine number is 3749 away from the 15015 DJ. Now, using the 1960 DJ3A# 17251, eng#3J166252 and comparing it to 1960 Surrey#17457, eng# 3J166468, we see that the Surrey is 206 units after the DJ3A, but the engine numbers are only 216 engines apart. Using the 1960 Surrey 17457, eng# 3J166468 and comparing it to 1960 Pepsi cola Surrey# 18478, eng# 3J167774, we find the two Surreys are 1010 apart in production and their engine numbers are 1306 apart.



Beginning and ending serial numbers for 1960 DJ3A are: 16643 and 19367, a total of 2724 units. There were 12 stripped chassis’ for 1960, but they carried model # 56437 rather than 56337. Those numbers went from 10003 to 10014.



The earliest DJ3A which has a mid to late 1959 production number and could have been a 1960 model I have with an engine number is 15015, eng#3J162503. The last 1960 DJ3A I have listed with an engine number is 19208 with engine # 3J168747. The vehicles are 4193 vehicles apart and the engine numbers are 6244 engine numbers apart. You can see what a problem we have in figuring out what engine numbers go where. Somewhere, Willys sold off over 2000 L-134 engines that didn’t go into a DJ3A chassis!



Confusing, yes. Helpful, I just don’t know! HAHA!

Hey Guys,

Haven't been keeping up but trying to catch up. Fyi...my Dispatcher titled Feb '62 here in Florida has a s/n #19525 (1961 production per Colin) with an engine stamp of#3J169168, and I'm pretty confident it's the original. Also, there's an over-stamp partially on top of the '3' of "361". It's a deeper stamp mark than the engine number stamp, if that helps the confusion any. Could that be for March 1961? or something else?

The Dj's seem really at random to what parts they used to build them. For example, mine has 1" front and 7/8" rear brake cylinders, but the manual shows they should be 1-1/8" frt and 13/16" rears???? I'm not sure which would be better to have. Any comments on that?

I guess it all helps make the Dj's more colorful and interesting...and this site that much more beneficial...Misery/confusion loves company.

Thanks!
