Harley FXR Shovel/Evo Master Cylinder, 1982-E87 (OEM #42446-82A)
Very clean bore with a good seal and piston set. And it produced excellent pressure in our bench tests. Chrome finish is faded and dated with lots of light scratches. Even so, it still shows clean. Attached switch has not been tested, but we left it in place to keep the port clean. And it's a part that can be used for reference when replacing.
Factory references show part number #42446-82A, correct for FXR, FXRS, and FXRT models 1982-early 1987. Specific to this master cylinder type is the machining for a side-mounted stop light switch. In contrast, FXST and FXWG models mounted the brake light switch remotely at the brake T location, and FLT versions featured one hydraulic fitting on the top, not two.
For a comparative reference (based on our research):
FXR: two top ports, one side port
FXST: two top ports, no side port
FLT: one top port, one side port
Please review your own Factory references to verify proper fitment and port configuration requirements.
