Branden scored on this rare, early 1945 print of a Parts List for the Universal Four Wheel Drive booklet. The use of the “J” logo so prominently is unusual. You can view my discussion of the “J” logo’s short history here.

DJ-3A Production Years and Serial Numbers

• CATEGORIES: Documents, Features This site contains affiliate links for which I may be compensated.

This image used to be on Bruce Again’s JeepSurreyGala website. I figured it would be good to repost them here. They show the serial numbers of DJ-3A Dispatcher and Surrey models over the production period 1956-1965. As you can see, the 1962 year is missing.

DJ-3A Carter Carb Forms

• CATEGORIES: Documents This site contains affiliate links for which I may be compensated.

Matthew was kind enough to send along a scan he did of the YF2392s Carter Carburetor used on a variety of DJ-3As. This is Form 5170A. A later form, 5170D, features the YF2392sa version of the carb.

I’ll include here a comment from this discussion of these same carbs, which also includes the linkage issue I ran into, that was copied by Charles Tate from a now-non-working-thread from an old CJ-3Bpage discussion (that quoted Bruce Agan):

Hi Barry. As a DJ3A Enthusiast I have to limit my response to that carburetor only.

Quote from Bruce Agan (jeepsurreygala.com) and premier expert on DJ3A Dispatchers September 20, 2011 07:42 PM

“the dj has always used the YF carb. 1955-56 parts lists show both the YF 2392 & YF 738S & 738SA carbs used on the early DJs. the YF 738 carb was the original carb used on the 4-63, VJ-2, VJ-3 (Jeepster”

Quote from OLDTIME from Deriks CJ3B bulletin board

“The specifications for the 2392 S are not identical to the more commonly found Jeep YF carburetors.
That implies differences such as the main metering jets, the metering rods etc. ”

Those specifications can be seen on Carter form #’s 5170 and 5170d

The difference between yf2392s and 2392sa was likely going from a air bypass check ball an air bypass check needle.

As said Barry I know absolutely nothing about the earlier CJ3A carbureator per sey. What I ‘think’ is that the YF Series carburetor used on the DJ3A dispatcher had a larger throat bore.

IF SO, then we can refer back to this comment from KEN (OLDTIME)

“Larger diameter throat bore = decrease air velocity = increase of the air % to fuel % = lean fuel mix =
better operation at high altitude or burnt valves at designated altitude”

If all of the above is true then it might also be true that better operation doesn’t necessarily equate to more actual horsepower???
