  View original topic: Need help to indentify main bearing size
Sandhi Thu Jul 18, 2024 9:20 pm

Hi, Volkswagen fellas.
I'm frim Indonesia, and recently re-building a 30hp 1200cc engine from a 1957 oval window bug. Turns out that the replacement parts is extremely hard to find, but I manage one by one. For the main bearing, since the supply is so limited, I found some for the engine that didin't match. And one day I was offered this main bearing, but the seller wasn't sure about the size.
Can you guys please help identifying for me?
Ow, the seller marked 0.5 case and 0.5 crank, but I won't be so sure


Please help, tx

Might be best to measure them and compare to the chart on Wolfsburg Warehouse website.

You're welcome. Best to measure all of them - individual bearings can get raided up by people who pinch one bearing and open another box to get just one bearing. Then these boxes of bearings can get mixed up over time...

From the markings on the label, might be +0.5mm and -0.5mm, but there is some handwritten notes so, best to measure each one.
