Motorshop Panhead Left Side Engine Case for Harley-Davidson FL/EL (1948–1954)

Accurately cast replacement Panhead left-side engine case with a blank number boss, designed for Harley-Davidson EL models 1948–1952 and FL models 1948–1954. Crafted in Taiwan, this left case uses loose roller bearings and cages for durability.

Designed for Panhead 61 inch or 74 inch applications, the case requires machining of the cylinder deck height for an exact fit with the right-side case, followed by line lapping of the case race for optimal sealing and performance. This left case does not include provisions for cylinder drains.

Hardware such as case race studs, breather tube, bearing, and drain plug must be ordered separately to complete the assembly. The design emphasizes precision and OEM-aligned standards, ensuring proper fit when correctly machined and assembled. This is not a bolt-on installation and demands technical expertise for installation and machining.
