I am a newbie with roller cams so I have a question.I have a comp cam with weber hardware including ,torrington bearing,washer,timing chain ,spacer and gear.When all the hardware minus the gear is on the cam I have 7/32" clearance to install the gear and it seems that is not enough.The gear it self to be installed fully on the cam shaft it needs 23/64's.Am i the only one or this is common issue ..
