On a Hotrod 4mm crank I have(banshee), the clutch side bearing has a groove in it, is that for a O ring or for the half-clip that holds the bearing? If its for the clip, what would keep the bearing from spinning?
thank you

thank youThe groove is for the Half clips. The difference in bearing to case bore size will keep the bearing from spinning.

Unless you have a real early set of cases, they will have the groove on top and bottom. I always put 2 clips on that side. I would recommend a TZ style or better quality Japanese bearing on the clutch side. They are worth the little bit of extra coin in my opinion.

i feel straights are more of a how far you want to stretch reliabliity and also hp and tq considerations.. i just ran tz full welded in the 350's and usually over a known 85+hp i would suggest straights a lil easier on the whole motor and easier/ less stress inside also translates to more useable hp.. ( in my opinion..)

Is there really any hp gains from a straight cut gear vs. oem. Any dyno or time reslults showing an improvement? I have considered it myself but some builders say it does nothing as far as hp is concerned.
