111-101-123 VW & Porsche Main Bearing Dowel Pin - Beetle Bus 356 914

Main Bearing Dowel Pin (8mm x 5mm) – 111-101-123

The 111-101-123 is a vital component for any professional engine assembly. During disassembly and cleaning, these small pins are frequently lost or misplaced. Reusing worn or damaged dowel pins can lead to bearing misalignment, which can cause catastrophic engine damage by blocking oil flow to the crankshaft.

These pins are precision-machined to a standard size, providing a snug press-fit into the engine case. Whether you are building a vintage Porsche 356, a 1600cc VW Beetle, or a 2.1L Waterboxer Vanagon, these pins provide the necessary mechanical lock to keep your main bearings securely in place under high RPMs and heavy loads.
