Vin help

Hi I was going to install this engine I bought a while back with basically no history that came with it anyway I noticed that the clutch plate was smaller then normal can anyone help me id my engine

That is a factory remanufactured engine block. The "VW recylcle" logo plus the "X" at the end indicate this. The original number was milled off.

It is not built to original standards and the number is meaningless. The letter "D" indicates it was rebuilt to 1200 standards, but the 1200 engine ran a long time and the specifics of what block and what internals were used for this when sold by VW and what are still in/on there are impossible to say without direct examination.

That is an engine serial number, by the way. Not a Vehicle Identification Number. (THAT number is on the frame under the back seat)

1200 engines did use a smaller clutch, 180mm in diameter. You might want to count the teeth on the flywheel.

I do not know how to fix this. All I can say is it all works fine for me with what I use, Firefox.

Thank you that was lotta good information so what I’ll be able to still mount this in my car even though it has the smaller, clutch and flywheel

VW made a lot of 6V, 180mm clutch, 109 tooth flywheel engines.

They also made a lot of 12V, 200mm clutch, 130 tooth flywheel engines.

There are also hybrids that mix those all up.

Further to the above feedback… you didn’t ID the model year of your car. Or more specifically the transmission you plan to mount the engine to.

VW switched from 6v to 12v between the 1966 and 1967 Beetle model years. The 6v flywheel is a smaller diameter and used a 6v starter with a different size pinion gear. I believe you can find conversion starters if desired.

A 6v (180mm) flywheel will fit inside a transmission bell housing designed for a 12v (200mm) flywheel, but the 12v starter will not properly engage the 6v flywheel.
A 12v flywheel can be made to fit into a 6v transmission with a little grinding/clearancing. But the 6v starter will need to be replaced with a 12v starter.
Each starter has a different diameter snout on the pinion gear so the bronze bushing pressed into the transmission will need to be replaced. There are 4 types of starter bushings:

6v starter in a 6v transmission (OE)
12v starter in a 12v transmission (OE)
6v starter in a 12v transmission (aftermarket)
12v starter in a 6v transmission (aftermarket)

There is also a change to the crank & flywheel around this same time. VW switched from gaskets between the crank and the flywheel to use of an o-ring inside the opening of the flywheel. The end of the crank shaft that mates with the flywheel was different between these two. I can’t recall exactly but I believe one combination of swapping worked while the other required machining the end of the crankshaft?

So the answer to your question of whether you can just bolt your 6v flywheel to your transmission really depends on which transmission your car has?
I would also point out that since most Beetles are 40+ years old it is not unheard of to no longer have the original transmission installed in the car. So just knowing the model year is no guarantee of the type of transmission. But the 12v transmissions are more common/popular for ‘67-later Beetles.

@Ashman40 - the 12V starter for 6V transmissions was available as OE (but NLA). Mine was VW stamped. I was told they came in some earlier buses or for the 12V m-code that was available in the mid 60s.
