Hi all,
The preface: My TO bearing disintegrated on me, so I decided to do a drivetrain overhaul. I've replaced all the tranny seals, the rear main seal, pilot bearing, etc. New Sachs clutch and PP, TO bearing, clutch fork, etc... Had the flywheel lightened and resurfaced (now 13lbs. down from 18lbs.). IE urethane motor and tranny mounts. New guibo and CSB.
The problem: In gear or out, clutch in or out, sitting still or driving, I get drivetrain vibrations most noticeable between about 2000-2300 rpms. It's kind of a "lump-lump-lump" feeling like a wheel out of balance would be, but in the drivetrain (for lack of a better description). Anything lower or higher in the rpm range than that and it's pretty much unnoticable.
My question is - should I be worried? Is this normal on new clutch installs that will fade with use? Or perhaps I'm just feeling the added NVH of my lightened flywheel and urethane mounts? Or is it symtomatic of something more serious like an out of balance flywheel?
TIA
