Not sure if any of you others have done this but FINALLY today (been meaning to for a long while), I replaced the grease plug on the whipper clutch with a 90 degree grease nipple...Ahhh, much easier to lube. Plug it had was basically an M8 bolt with a 1.25 thread pitch...could match the 8mm but not the pitch so out with the ol' tap and die set and Bobs now me uncle.
Ahem....Tip & Trick...If possible or most importantly practicle, replace plugs with nipples...
