24692-39 Lower End 45CI & Big Twin Side Valve Models

This Samwel Supplies lower end part is specifically crafted for the 45CI Sidevalve and Flathead Big Twin engines. It offers a precise fit for 45CI models from 1937 to 1973, including Servi-Car models, and also covers the 1937 to 1948 Flathead Big Twins. As a replacement for OEM 24692-39, this component is manufactured to meet the high standards required for vintage engine work. Keeping these older motors in top condition requires parts that can handle the heat and stress of operation while maintaining original clearances. Samwel provides the reliability needed for these classic powerplants, making this an essential part for any mechanic’s bench when working on a sidevalve bottom end overhaul or routine internal maintenance.
