Moderator notes from EverettB:
The original photos below are dead so here is another example of the engine case stampings:
Right side case half, on left side of generator stand:

This stamping is:
3 5 16
indicating
3rd day of 5th month (May), production shift (1), year (6)
so this case half was produced during the 1st shift, May 3rd, 1956

Left side case half, to the left of the oil pump:

This stamping is:
3 5 36
indicating
3rd day of 5th month (May), production shift (3), year (6)
so this case half was production during the 3rd shift, May 3rd, 1956

Overall location of left-side stamp:

Original post is below
==============================
Hello. Can anyone tell me what year this case would be?

The case number is 1-0268989 Be a 25hp. January of 51 correct?

looks like 19 Dec. '52 to me, perhaps a restamped replacement case?
need more pics of the serial number stamping area etc.

He asked for the serial number, if you give us that we'll narrow it down for you..... :wink:

As I understand it, it is in the form of day month (shift)year.

19 = day

12 = month

22 = year (2nd shift) 1952

0 = 1950, 1 = 1951, 2 = 1952, 3 = 1953, 4 = 1954, 5 = 1955, etc

I dont have the case at my house....
But the case number is. 1-0268989

The reason Im confused is because of this ad. It says May of 1951.
IE: (28 05 11) 28th day 5th month 11th production year.

Yes, 1-0268989 IS a jan '51 engine number

The 11 in (28 5 11) is not the 11th production year.

Send pics of the Engine number stamping area on the case when you
can.

These arent much but its all I can get.

This is my block that I have for sale. I thought it was a 36 hp. What are the differences visually between a 36 hp long block and a 25 hp. The reason I ask is that the numbers stamped on the case identify it as 25 hp but there is also a stamp underneath the numbers that say it has been rebuilt. Just want to make sure I am listing it correctly.

Damn I am ignorant on these older smaller motors. :oops:

Here are some pictures I just snapped. The first is the engine number. You can see below it that there is a very faint stamping. I believe that is says factory rebuilt, but the letters between the f and y are really faint. I can't seem to get a non-blurry pic with my POS camera.

The other pics are to help everyone identify whether it is a 25 or 36 hp block.

That block has Jan 1951 serial number but it has 36hp heads and the bottom appears to be 36hp as well. The block could still be 25hp with the cylinders bored out for 36hp pistons and heads.

I would guess that is a dealer replacement case. Weird serial # stamping, later head studs, drain plug in sump plate instead of case, and so forth.

Original Beetle 1- engine numbers have more dashes.
Example

Since it's a replacement case, how do you tell that is not a 1962 date stamping?

Mon Oct 05, 2009 5:12 pm

It looks like there is a filled-in spot for a drain plug in the case.

So Seeing this case has been cut in multiple areas, And its locked up. The jug holes are opened up. cranks been cut. ect. The possibility of it being useable is very slim.

Mon Oct 05, 2009 9:06 pm

What is the casting date on the other half of the case? Should be the same date or within a day.

Tue Oct 06, 2009 11:50 pm

Where do I find that?

Tue Oct 06, 2009 11:53 pm

The other stamp is down low on the left side, closer to the pressure relief valve.

I think we're looking at a 1962 crankcase, not 1952. It has the larger, 40hp sump plate and the spacing of the "1-4-3-2" is much closer than earlier blocks, but the lettering does not appear as large as the mid-'60s cases.

Wed Oct 07, 2009 6:52 am

62 would have the bolt on generator stand I think. It's possible it is a replacement engine that was made much later in the production.
