Hello
Trying to figure out if my motor is within the correct time period for my early 1947 CJ-2A

CJ-2A - 81299

Here is what I found on the block

The "clock" handle points at the second dot from the bottom left.  Its stamped 6-19

Numbers are -- 641087-L-W8    A-N   R-N2

Motor serial number behind the oil canister has been ground off
Motor serial number behind water pump reads  BE5138 CAA  letters and numbers a crisp and straight.
The last "A'  has a "L" stamped in it.  Looks like  it was done with a screw driver.
Motor color reminds me of the old bluish green.  Not as green as a 225 V-6 Dauntless.

Any help will be grateful!

Jim

Yes, on engine colors from the factory. 

I have been with this Jeep since 1961 and it the motor was never rebuilt sine then.  Soooo  somewhere pre 1961  the motor had work done and painted bluish green or is it greenish blue.

LOL My Jeep has been in the family since 1962. its a 48 per the title but in 62 it was already on a 56=57 CJ5 frame and suspension and wore out to the point dad had to drag it home 11 miles with locked brakes (luckliy on gravel roads mostly) So its amazing what happened to these relatively new vehicles back in the day.

Motor casting numbers are -- 641087-L-W8    A-N   R-N2

Did  a little research and found that the vehicle was made in '46 not '47
Must have been'46 left over and re-registered as a '47---thus a early '47/'46---yeah Jeep, LOL

Jeep did this trick clear up until '69/'70 when the gov't stepped in and spanked them.

According to the sherman williams paint chart, this 2A should be  Harvard RED. 

NOPE!  It's Luzon Red which was offered in '47

The wheels are black with a ivory stripe....However,  according the color chart,  the ivory on black was offered in '46 with the Harvard red color.  NOT offered in '47.
  
The '47 color chart shows Luzon red had Beige wheels with a Luzon Red stripe.   

Sorry for all the B.S.  Thought I would simply add to the confusion, LOL  

Basically, it seems, Jeep did what ever they wanted too and used what they had on hand. 

Please pitch in and help add more to the confusion, LOL

good luck with that! Its like the jeep buffet. They walked down the line and took a scoop of this, a scoop of that and in the end, they had a jeep. LOL!

I recently took my oil filter canister off and found these numbers. I do not understand what they represent. Can you clarify for me?

I am not versed  on IDing stuff but there are guys on hire that could ID the head for you.  What are the numbers right behind the water pump read?

I'm good with the numbers behind the water pump. However, I read (somewhere on our forum) about the numbers under the oil filter bracket the give you a greater insight on the motors date(?).

The  numbers under the oil bracket, on top of the head, are the head ID numbers..  They maybe different from the block numbers. 

Directly behind the oil canister, on the block, is a stretched out flat oval spot the MAY have a block number.  Plus the block number may also be behind the water pump.  I have seen both places stamped with different numbers.  Most likely from a re builder.

Finding when the head was made will help you find if it is era correct.

My early '47 2A's head has a front water by pass outlet, like the 3A has, so I'm not sure if it is a 2A.

  640161 is a casting number, and may have also been the Willy’s-Overland part number.  7/18 is a casting date code. It may mean seventh month/eighteenth day, but I don’t know how to tell what year. W-1 is a Wilson Foundry mold number. 
  MB’s and GPW’s had their engine serial number stamped on the oval pad behind the oil filter. CJ2-A engines were stamped on the deck, ahead of the head/behind the water pump. 
  Willy’s-Overland was very organized in what they did, and were not nearly as haphazard as you might think. A lot can have happened, and has, in the 70+/- years since your jeep was built.   BW

CJ-2A 81299 would actually be a 1946 CJ2A        1947 didn't start until 83380     The 641087 casting didn't appear until mid to late 1947.......

Yes the serial number shows late '46    
paint is '47
wheel paint totally odd...black wheel, ivory stripe. 

The head has a 1/4"? plug where the 3a by pass hose would go.  Not sure if that's correct for a 2A.

No, it’s not. All of my 2A’s, all of my spare 2A engines, and all of my spare 2A heads don’t even have the flat spot where the hole would go. I do have a spare 3A head that has the flat spot but it’s not drilled. I also have a friend’s jeep here that has a 640161 cast head that does have the flat spot but it’s not drilled. I’m not sure whether the 3A’s had a bypass hose or not. I’d have to ask Tim on that one. BW

GEEEEZZZZZZZZ

This 2a  has a lot of oddities

I will take a pic of the head.   There's a good possibility that the re-builder had to change out the head. 

By reading my above posts, this 2a is a interesting  one.

Hi Jim,

Not sure this will help, but my block was also painted a bluish-green. the photo below shows it prior to clean up etc. It was originally rebuilt by the U.S. Army Ordnance Corps in Germany and it appears that they may have used that color paint.

Below is the rebuild tag.


Below are newspaper articles which are reporting on the activities of the facility. Who knows, my block may have been one of them in the line up after being rebuilt on 5/21/59.

That is the color. 

 I have seen a few pics of other motors with it.  Had to laugh, Who ever painted this motor, painted the front of the motor including the cam and thrust plate, ETC.  

Thanks for the reply and pic, Jim
