|More CJ3A Restoration Pictures...
A number of hours were spent cleaning years of rust and grime off
of the frame. Nothing that a lot of hard physical labor couldn't take
care of! The frame was coated with a substance that looked like
brown bubble gum. What I have heard is that farmers used to spray
oil underneath and run it down a dusty road to undercoat and
preserve the Jeep. Well, it saved my frame! A high temp pressure
washer, wire-brushes, scrapers, and emory cloth all helped prep
this frame for the 2 part preservative and undercoating process.
The silver coating pictured below, bonds with the metal and
neutralizes any remaining rust in preparation for the thick black
sealant / undercoating. This stuff was too thick to spray on, so I had
to brush it on. The frame was easy to flip around from side to side
with the axles and wheels still on. This also allowed me to take
advantage of some nice March weather while the breeze safely
carried the noxious fumes away!
Engine, Transmission, and Transfercase:
The CJ3A came standard with the 134 cubic inch flat-head 4. The motor is also referred to as the L-head or the
"Go-Devil", a name well earned all over the world during WW2. A T90A-1 transmission and a Dana Spicer 18
twin stick transfercase were also standard equipment.
|Many parts were interchangeable between the CJ3A and earlier CJ2A's. My engine (above left), while correctly
a 134 L-head, has "clock block" casting marks indicating that it was from an early CJ3A or more likely a CJ2A.
My T90A-1 transmission (above right) proudly sports a "5-2-51" original CJ3A casting mark!
My Flat Head 4 had seen better days! By the time I got it, it
needed a total rebuild. The head was cracked, the
camshaft worn, the bearings shot, and 2 cylinders badly
scored. Virtually every moving part was replaced. The block
was sleeved, bored, planed, and completely rebuilt!
The pictures above and to the right show the engine
reassembled and repainted. My research indicated that the
engines were originally painted black or gray from the
factory. I picked black since it would go better with the
yellow paint scheme I had in mind for the body.
The 3 pictures above and to the right show the original
PTO, Dana Spicer 18 transfercase, and the bell housing.
The picture to the immediate right shows the three after
they were restored, reunited with the transmission, and
All of the gears had to be replaced due to rust from water
laying inside them. They were quite foul looking and
smelling when they were first opened up!
