Motorshop Left Side Engine Case for Harley FL 1965–1969

Left side engine case for aluminum electric start inner primary application on 1965 Panhead and 1966–69 Flat Side Shovelhead engines. The Motorshop Left Side Engine Case is specifically designed to fit Harley Davidson FL models from 1965 through 1969. Crafted in Taiwan, this engine case requires professional installation, including precise machining of the cylinder deck height to ensure proper alignment with the right side case. It’s not a bolt-on install; case line lapping and potential clearancing for the cast inner primary vent tube are necessary for optimal fitment and performance. The case features a blank number boss for customization or identification, providing flexibility for rebuild or restoration projects. Compatibility with essential components such as case race cylinder base studs, breather tube, bearing assembly, and drain plug is maintained, and it is compatible with Timken roller bearing assemblies, all sold separately. For best results, use this case with the #10-0955 Replica Bare Engine Case Set, ensuring a cohesive rebuild process. The case’s durable construction and precise fitment make it an excellent choice for custom builds or restoration of classic Harley Davidson FL models, ensuring reliable performance and authenticity. Accessory items include inner primary cover bearing, replica inner primary cover, Panhead engine case set, and left crankcase main bearing set, providing all necessary components for a comprehensive engine rebuild or upgrade.
