Dj-5c Part Identification?

Forgive me, but my background is in MOPAR and an odd AMC Concorde in the 1980's. Totally new to the Jeep lineage.

Spent yesterday doing a serious once over on my 1974 DJ5C, and I've found several pieces that I gotta say, I have no idea what they are!

a) Inboard of the rear bumper, on the left side, buried up there is a canister with 3 ports on it. Two are attached, third is dangling. It looks like it is fuel related, but I can't be sure. It isn't the evap can, which is under the hood...

b) Right behind the oil filler cap on the rocker cover is a beautiful hole about an inch in diameter. Something probably went there, right? There's already a hose on the firewall side of the cover, which I am guessing is either the PCV or possibly some sort of air vent. Since the jeep is missing the air cleaner completely, I would guess that the hole was fed from there, but I may be wrong again.

c) On the left side of the Carter carb, below the throttle linkage, is a plunger type item. It is stiff as wood - you need to really work on it to make it move. And it has an electrical connector, so either it's a sensor or an electronic actuator. What is this?

d) That rubber bladder on the inside left fender - that's my windshield washer reservoir? Really?

e) Any easy way to identify the automatic transmission I have? It's got a trans cooler in the bottom of the radiator, and the pan has four tiny little dimples in the corners and a silver-dollar sized one in the front left side. I didn't think any of these came with cooler lines! Sadly, I forgot to count the number of bolt heads holding the pan on. Meh.

f) Last one for now. Somebody cut and tapped into the orange wire on the main wiring harness on the firewall. They used wire nuts to splice in some extra blue wire and snake it back through the grommet into the under-dash space. Any idea what the orange wire is supposed to be, so I can figure out if I can remove that after-market wire?

Thanks again!

 

Not sure about all of them.
a) Probably an expansion tank for the vapor recovery system. A '72 CJ used an expansion tank and a '73-on used a liquid check valve. You could look at the '74 TSM here http://oljeep.com/gw/74_tsm/4-FuelCarburetion.pdf for a picture of the '74 system to compare to.
b) PCV valve or filtered air for the crankcase from the air cleaner. Might be shown in 4A of the TSM linked above - '74 should be the same.
c) Idle stop solenoid?
d) I guess. Cheesy, but maybe ok for a postal.
e) Wikipedia says
DJ-5C (1973–74): 232 cu in (3.8 L) AMC Straight-6 engine, T-35 or M-11 automatic
which are both Borg-Warner transmissions. I think the Borg-Warners have a separate bolt-on (iron?) bellhousing, and I'm sure the later Torqueflite case is one piece. Jeep didn't use the Borg-Warners for civilian cars after 1965 (only in early Wagoneers), and never in CJs. Maybe an AMC car forum could help, or maybe there's a DJ forum out there somewhere? Possible there's a Yahoo group.
f) Wow, there's no way to tell that from here, I think. Somebody out there might sell the DJ service books, or try to find another owner that has one. You need a wiring diagram, if you can't figure it out by tracing the wires. If it were me, I'd trace it out and see where the wires go.

Here's a Facebook group that might offer some tips - Jeep DJ - Postal Jeep

 

Good pictures of the engine top here,



from 74 DJ5 Transmission Problems
but the posters in this thread are more wrong than right. Looking at other info, the M-11 has a cast iron case and the T-35 has an aluminum case, both with separate aluminum bellhousings.



Is your starter on the left or on the right side? There are 2 different 232s, and I had thought that the early ones got the Borg-Warner and the later ones got the Torqueflite.

 

My starter is on the right hand side, sorta buried below the distributor and next to the master cylinder.

What confused me about the transmission is the cooler lines. Everything I've read said that there are no cooler lines on a BW transmission. But they are there, and they connect straight to the bottom of my radiator, sort of where I'd expect them to go in a smaller vehicle (my bigger truck has a separate radiator for transmission).

I'm gonna go diving underneath the DJ tonight, maybe I can find something distinctive, like a casting or part number. Maybe I'm ignorant, but something just feels fishy.

 

I don't know the Borg-Warners well enough to comment on whether there should be cooler lines or not.
Could be a Chrysler TorqueFlite transmission. Those definitely have transmission cooler lines.
DJ-5D (1975–76): 232 cu in (3.8 L) AMC Straight-6 engine, 727 TorqueFlite automatic
Just because Wikipedia says it has to be a DJ-5D to have a TorqueFlite does not totally rule it out. Stranger combinations have come from Jeep.

I'm assuming you have a build tag or such that tells you it's a DJ-5C.

A B-W will absolutely have a separate bell housing. The TorqueFlite case is one piece.

Starter on the right is correct for the later 232. This means the bell pattern is the AMC "unified" pattern, same as the 258, 4.0L and Gen 3 V8s (304, 360, 401). The earlier 232 "Rambler" engine has a different and distinctive bell pattern, various internal parts and deck height. You'll notice there's no starter bump on the passenger side of the T-35 pictured above. Your 232 is an excellent engine; economical, durable and reliable, if not exciting.

 

Yeah, the sticker on the dash says that. And now I am sort of convinced of it.

It's a B-W. I found the builder plate, although I can't see enough of it to guess at the model number.

I'd give almost anything to have it, in an overnight miracle, convert itself into a Slant-6. There's nothing wrong, per se, with the AMC engine. It's just that I love the sound of the 225 when she ticks over. For kicks, I have included the build stamp off of the engine block, so I know that this is the correct (and probably) original engine for the jeep. I suspect that my odometer isn't right, as it's only showing 2670 miles, and that is oddly low for a work vehicle of this age.

 

I suspect the the odometer has just rolled over from 100,000 miles. Vehicles the age of our Jeeps only counted to 99,999.
A Postal Jeep could have rolled over a couple times.

Sweet Yumpin' Yimminies! I found it!

According to some of the other AMC / AM General forums, that transmission tag has all the info. The first line, half obscured by crud, is the AM General Part Number. And if you look that up, you see that this is a BW M-11 transmission.
I google-found a scanned PDF of the transmission details, and it reports that a Jeep DJ-5C with my VIN had the M-11 installed - the alternative was the M-43.

So, now, I am enlightened.
