many thanks
it looks like a 1948 but it does not have the "zero" in front of the number.
What is your opinion ?

[virtanen]

There was no zero on the front that time, but I wonder the letter "A" as the last digit?

it looks to me that the A at the end is not really an A but it looks to be more like a "slash" which ends on top of the welding area

[peter schepens]

Could the A mean Austausch? It seems that the Zundfolge is partial grinded.. Just an idea.

what do you means by "it all looks wrong ?"
The only thing I know is that the car , most likely , was produced for Austrian market.
It has all accessory as old engine including the heater duct.

[rod_vw]

Sorry, I was looking at the casting marks, the poor visibility of the firing order markings and the inclusion of the 'A' after the numbers.
Maybe a different view of that would be convincing enough to believe that it was never an 'A' but a numerical digit. As far as I am aware VW (in this era) did not use 'Alpha' characters, they were all numeric.

If we ignore the last character i.e. 1-115107 then the engine was made in the latter part of 1948.
If we consider it as 1-115107? then it was made in September 1955
{Dating from Progressive Refinements.}

In 1948 it would have been a 25ps unit and in 1955 a 30ps one. Which is it?

Now I hope that you understand my comment.

Rod,
i really appreciated your explanation and the time you spent to make it clear to me .....I am not a specialist !
I do believe that the last carhacter is a slash instead of a "A" .
can it be the case ?
How can I determine if it is a 25hp or 30 hp ?

Tnx again

[rod_vw]

Even the '/' or "\" would not be correct but let us not be too concerned. It is an early VW engine and hopefully worthy of further use.

As a quick identity to differentiate between 25ps & 30ps if the cylinder heads are on the engine and covered by their tinware a 30ps will have raised pressings 'outboard' of each pair of plug holes to clear the cylinder head securing nuts. If it is a 25ps then these are absent as the head studs do not protrude into this area.
If the covering tinware is absent but the heads are in place then notice that the head securing nuts are normal hexagon on a 30ps and special recessed socket nuts on a 25ps.
If no cylinder heads but cylinders visible then the nominal bore size of a 30ps is 77mm and 75mm for a 25ps.
If no cylinders etc then it is difficult without detailed examination to determine the difference.

Are there 3 circles with numbers on the Left side of the generator stand or near the center seam of the case? Are there any dates on case near the oil pump or oil dip stick area?

Mike

[virtanen]

It's a pre 1950 for sure, the crank case style is such. Serial number location relation to the spark firing order is pre 1950.

Virtanen,
can you provide me more details to understand your assumption ?
Anything more I have to cross check on the engine ?

What is the casting date on the case?

May be on the left side of the generator stand. It should have a circle with three numbers. They'll be one on each case half.

Look through this thread.
