MCS Alternator Rotor/ Clutch Shell & Sprocket Assembly

MCS Alternator Rotor/ Clutch Shell is OEM style replacement reference 36791-84. It comes with primary chain sprocket combo.

Note: Replacement clutch hub ball bearing is separately available as 556626/36799-84.

Features:

• Rotor Magnets are encapsulated in a stainless steel shell to prevent magnets coming out, which was a common problem with OEM equipment.
• Comes with Ball Bearings

TECH TIP on L84-90 XL Sportster: MCS do not recommend, to add clearance which reduces output. Better is installing new bearings.

• Note: From 1991-on the alternator was moved and the rotor is run on the sprocket shaft. This fixed the problem.

Compatibility : L84-90 4-sp XL (NU)
