You might think knowing the part number would make buying a replacement part easy. This is not always the case, particularly when you are considering used parts. Case and point is the crankshaft pulley.
The 914-6 engine is essentially from a 911. The air-cooled 911 have no less than 4 different pulley sizes, not counting AC versions, and I’m guessing several flavors of those given original and after market. There are plenty of used pulley for sale with photos, but they rarely include the size. The pulleys I’ve seen don’t usually have a part number on them. They do have a variety of timing marks. This makes buying something as simple as a replacement pulley much more involved than it should be.
For the record, the 914-6 (Non AC) part number: 911-102-017-50 shares the same part number as the 1969-73 911 and appears to have a diameter of 116.5 mm. If this eats up much more time, it will probably push me to buy a new one from Sunset.
