1947 cj2a build, 33's D18/D20 hybrid etc

I recently bought another flatty. A 47 cj2a. Its still sporting the original L-head (which will be staying) a t90 and a d18, for axles its got a 19 spline tapered 2 piece D44 rear and a D27 front from an early 5. It on some 33's which will also be staying.

Here's some pics (also shown is my 51 cj3a resto project)



I am planning on swapping the t90a for the slightly better (lower) geared first of a t90c, which I already have the parts for. For a transfer case I will be using a hybrid d18/d20 set-up for twin sticks that will allow independant use of either axle.

I will be swapping to a later flanged D44 from a cj5 and a disc braked D30 also from a cj5. Both with 5.38 gears and lockers.

I have already completed a saginaw p/s swap. I will also be swapping in Herm the overdrive guy's master cylinder kit to go with my new disc brakes.

Building it for moderate or less trails. Going for reliable, fun little rig!

more pics to come when I get some free time to work on it.

Here is another pic of the 51 with the new panels on the body tub for good measure

I will probably catch alot of flack for my motor choice, but I like the simple little engines, got kind of a soft spot for them. I guess if I was rich, I'd be called eccentric, but I am not rich, so I am just crazy.

Started working on the centered, flanged Dana 44 rear today. Plan is all new bearings, races and seals. And a 5.38 ring and pinion set.



Of all the places that I have found Mouse nests on/in a jeep, I have never seen one in a brake drum. Pics of the nest after I cleaned it out

Axles all taken out, Nice and beefy for a light little Jeep.

One last pic of the parts washer I got for christmas. Someone must know about my obsession with old greasy jeeps....

Its gotta stay for atleast a little while. Its a great little engine. Not super powerful, but torquey down low. And its super easy to fix. I have always been a fan of the underdog.

All the guy sin my club are busting my balls for keeping it in there. They all think they are skunk me now that my huge wrangler is gone. I can still drive better than most of them though.....

Anyway thanks for the kind words

Congrats, on your purchase. I own two '52 M38's. Pretty much the same thing as your CJ3A. Just military. Glad to see your sticking with the "go devil". They great little engines, easy to work on. Love flat fenders hope to get one of mine going one of these days soon. Good luck, nice flat fenders!

Thanks everyone. I have always been into flatties, I got the 47 also shown when I was 15. I enjoyed it for a few years, but it started to get rough. I stored it until I had the skills and funds to do it right. But I came into a deal on the cj3a that I could not pass up.

I love the simplicity, the noise/smells (although some of the smells are less than pleasant...) And I can't wait to beat up on some bigger rigs with 33's and a flathead! The thing is so small it fits where others won't and gives me more options for lines!

Got a little more work done i=on the D44 rear today. Ring and pinion installed. Got a good gear pattern. Got the housing primed and cleaned up and primed the brake backing plates. Here's the proof.



And here is a picture of the shop for good measure.

Not sure what that is, so I guess not.

Here is the pics of the hybrid D18/D20. Its a D20 housing from a J-truck, 1 1/4 intermediate shaft D18 gearset, with the sliding gear from a Bronco D20.

For anyone interested, the reason for using the J-truck D20, is that the case requires less grinding to fit the larger size of the 2.46 low range gears. Also, The J-truck version of the D20 only has one interlock pill. It will allow the use of each axle independently with no other mods other than a twin stick conversion.





The substance on the gears is white lithium grease. It works as a good assembly lube, then dissolves when the case comes up to operating temp the first time.

Got the secondary shaft put in, all those little needle bearings are a pain. Unfortunately, that is as far as I got. My rebuild kit did not have the 3 square syncro dogs, or the 2 springs for them. Another call to Novak got them coming.

Heres pics for proof:

All the pieces on the table


installed secondary gearset



More to come when I get more piecey parts
