cj3a 31865
« on: August 14, 2017, 09:40:49 PM »
Well, I'm new-ish to jeeps, new to this forum, and new to the 'postimage' site, so I may really mess this up, but here goes.

I recently acquired cj3a 31865, seen here-



I got this from the grandsons after the grandfather had passed away. The grandsons just wanted to sell, they didn't seem interested in their grandfather's vehicle.  Granddad had fishing lures stuck to the dash, deer hunter scent killer, tools, jeep parts, fencing tools, camo spray paint, several small fluid pumps, jumper cables, and just a lot of stuff piled in the jeep. Non-working fuel pump still in place but replaced by an electric fuel pump sort of improvised into use.  I had the impression the granddad's jeep maintenance level had declined as he had declined, but I think the jeep must have been stored under cover much of the time, due to the amount of paint left, and less rust than I expected. I wish I could have met the gentleman, and I hope I can do justice to his jeep.

Here's the vehicle i.d. number.  It was a bill of sale transaction.  No license plate on the jeep, no old inspection sticker on the windshield.  I don't think it had been registered in a long time. I'm thinking 1949 from info from online. I read it as '31865'.



Here's the engine serial number and a rebuild tag riveted to the engine block.  The engine number ends in '20371 but I could sure use some help on that first part, -- not sure what to expect.  From reading, I was expecting the engine number to be higher than the vin number, -- more engines produced than vehicles, is that right?




I've had the starter rebuilt (by J and I in Marshfield, Mo, -- not far from me and so far I'm very happy with their work) and ready to install.  I re-purposed an old clevis pin to use to bang the old bushing out of the bell housing and insert the new one. I read online there is supposed to be some sort of freeze-plug-like plug on the back side of that opening to keep stuff out of the bushing, can anyone give me any info on that? I can do just a bit more than turn the lathe on, --- here's my bushing tool/ clevis pin



I have the right fender off, --- making more room to get to the starter bushing, and just getting acquainted with how many captive nuts are froze up or missing, sheet metal tears, --- the hat channel that supports the fender is broken, the air shroud is bungee corded to the rear of the radiator, the bolts holding the grill to the frame are missing, etc etc. But mostly the jeep seems original and not in bad shape considering 68 years of age.



I initially thought I was going to encounter a 6v generator, but I found a delco-remy 12v generator and the corresponding voltage regulator --- vintage, but clearly not original.  It had a 12v battery when I got it, but the grandsons had bought it, and they probably didn't know 6v existed. The generator is in the rebuild shop (--- I don't trust myself to rebuild starters and generators . . .) and Dad and I are to pick it up tomorrow. Dad's a wwII vet, he went through basic in the summer of '45 training for the invasion of Japan, but after the war ended suddenly, he served 18 months in a truck maintenance unit near Naples, Italy. At nearly 91 he is doing well and  having a blast playing with jeeps again.

My general plan is this:  I don't think it's been all that terribly long since this jeep ran.  I blacksmithed a 1 3/8 hex socket to use to check to see if the engine was frozen up, and it turns fine. Oil and antifreeze both look ok. Only one tire wouldn't hold air.  I saw this advice somewhere on this site, --- get it running with the least disruption possible and catalog and photograph the problems and current condition before doing anything drastic. That sounded like a heck of a good idea to me.

Well, as time goes by I'll try to post mostly an account of what I have actually done and not too much about pipe-dreams of what I hope to do.

Nice Jeep!!!

I'd try Walcks 4WD for that starter bushing plug. I've also heard that a coin will fit in there, perhaps a penny?

Could that engine number be 4T20371? If so it's not original to your Jeep.

Can you post a photo of your fender while it is off? I'd like to see the inside of the splash apron.

Bob --

Here's a shot of the fender.


Here's the frame w/o fender.


It took me a bit, but after some time I figured out pretty much everything useful I found online was on your site, so thanks very much, and I'll be getting your book!  In the information online you mention and show photos of the presence or absence of a couple tabs and bolts on the driver's side.  Here's that area under the driver's side fender.


It's a pleasure meeting you online!,

Great thread and great pictures.

That jeep has had a lot of adventures, and more to come!

I've taken the grill + attached radiator out. Trying to figure out how the air shroud should be attached to the radiator was the trigger to take the radiator out. The air shroud has been bungeed to the radiator for awhile.

The radiator shows a big soldered area from a repair.  The bolts holding the grill to the frame and cross member were all missing. So it seems like the previous owner had problems here.



 It looks like the shroud was attached by pop-rivets in the past and these have broken or pulled through. Not sure at all how to go about getting these out.





Here it is after grill removal.



The pop rivets are just going to turn in the hole when I try to drill and then there is the risk of drilling too far and damaging the radiator, which would not be good.  The best idea I've come up with so far is; file/grind the exposed part of the pop rivet off. Slightly enlarge the hole it is in until the swollen part of the pop rivet will come out.  Fill the radiator with water and silver solder a small sheet metal patch-with-hole to repair.

Originally the shroud was attached to the radiator with SHORT sheet metal screws. Long screws will puncture the core.
