S&S gear drive
Not impressed with the machining tolerance of these gear sets. Crank runout is .0003", yes thats right .0027" less then max. The 2 cam gears aren't to bad for clearance, but the outer cam gear and crank gear are pitiful, some teeth have .002" and some have .0005". The engine runs fine but the noise that travels through the valve terrain and into the rocker box is awful. It is not gear whine, it is not collapsed lifters and it is not lash, it is simply noise. I did a search before I installed this garbage, specifically looking for noise complaints and found nothing. I wish S$S would warn that there will be noise. I guess I knew there would be some noise, that is why I did a search, if the gears where machined properly, I wonder if they would be quieter.
My engine has again as much noise as it did with the chains, ls this what others are finding?

Have you listened to it with a stethoscope, is the noise transfering through to the rocker box? My gears sounds fine listening all around through the cover, the sound of it drives me nuts.

All my noise is in the cam chest area, not in the rocker boxes. It runs good though so I'll just enjoy the ride and get used to the noise.

I have the 510G cams also and other then a bit of a "whine" when installed they seem good. I have a few
hundred miles on them now and they are not making as much noise so for me all is good.

Mine have been noisy since install. Almost sounds like a loose pushrod, but stethoscope it and from cam chest to rocker boxes and all sounds normal. Been to 4 different shops and no one can find where it's coming from.
