Willys Overland CJ-3A
This is Gary Keating's CJ3a
The Willys Overland CJ-3A was produced from 1949 to 1953. It was to replace the CJ-2B. The most noticeable difference is the windshield of the 3A has the wipers on the bottom. Willys Overland made other changes to give the driver more room. The driver seat was moved back but it still had a 80 inch wheelbase. It had a taller windshield gave more headroom. All CJ3b's came with a 6 volt electrical system that included a generator. It is a common mod to upgrade to a 12 volt system with an alternator.
Engine
The Willys L134 "Go Devil" engine was used in the CJ-3A. It was a 4 cylinder that produced 60 horsepower and was nicknamed the “L134 "Go Devil"”. While the majority of automotive engines have the valves in the head, this engine was an L-Head design. That meant the valves were in the engine block.
Drive-train
The CJ-3A came with the T90 three speed transmission. Click here for more info on the T90. -->> https://jeep-cj.com/community/threads/manual-cj-transmissions.43554/#post-394889
The transfer case was the Dana 18.

The rear output is on the passenger side. It is a strong transfer case. Warn made an overdrive for the Dana 18.
The front axle is a Dana 25 with an enclosed steering knuckle.
Originally Willys Overland used the Dana 41 rear axle in the CJ-3A. Starting in 1951 the Dana 44 was used.
Accessories
The CJ-3A was often used on farms. The CJ-3A could be used to plow.
There was a lot of accessories that could be attached to the PTO.
