Alternator Clutch

I'm having a charging problem on my 82 CBX. Have replaced the battery, checked the brushes, rectifier/regulator,etc. I've noticed some oil in the area of the clutch plates. Is it normal to have a little oil in this area or could this be causing the clutch plates to slip?

Doug,

Oil in the clutch area is OK, the clutch is designed to slip when engine is accelerating. In fact, the plate faces should be lubed with Moly Disulfied when re-assembled. there are lots of tech entries on charging problems so take a look there. Also check the entries in one of the other CBX boards.

Doug,

They put the seal in there for a reason, it's a friction drive metal to metal clutch, anything you do to it that reduces the friction will cause the clutch to slip, Good Luck,

Hi Folks,

No expert here myself - but I thought that the alternator clutch was intentionally oiled through a metered orifice in the primary shaft end and that the oil in alternator clutch housing was drained through a return hole to the transmission cavity.

Further - isn't the alternator clutch housing vented through a tube to the airbox thereby serving as the engine's crankcase vent? And isn't the alternator clutch plate affixed to the primary shaft (Plate A) grooved for oil passage? Hard to imagine Honda would have allowed the plates to interface without oiling.

Cheers,
