Product Description

Harley Davidson FXR Shovelhead/Evo Master Cylinder, 1982-E87 (OEM #42446-82A)

OEM unit in nice, clean condition.
Original black paint finish still looks good, and we have disassembled and inspected, and the bore, spring, plunger, and seals are in good shape, and some fresh fluid is still present.  Produced excellent pressure in our bench tests.  Attached switch has not been tested, and replacement should be assumed.
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.
  • Condition:  Used
  • Type:   FXR
  • Vintage:   1982-Early 1987
