Grunt, I was directing my query to "Now, that is for an engine built from a balanced crank and a balanced pulley and a balanced flywheel, and we still ended up balancing the flywheel plane for EVERY engine *after assembly.*
So, fully machined parts assembled to a balanced crank can and will...
Thanks Greg, this just reaffirms the old "you get what you pay for" adage. Soon, a brand new OEM FW should be installed, and my hope is that this will restore the balance.
Can you explain why so many people manage to get away with machining their FW without noticeable issues? In my case, I...
Thank you for all of your advice! I'll call up these shops and see if I can find another. I just took the service manager's word (back when I still had some trust in the garage) when she said she called around.
And Rod, I'm glad you learned that lesson for all of the rest of us!
Gruntguru, 1 and 2 are correct as you describe. I already intended to suggest this option to the mechanic, but I don't know as yet what their excuse will be.
Thruthefence, this is not possible for the same reason it was not possible to get the balance on the flywheel checked on my 2nd visit...
I doubt that could be the problem then, as the vibrations are consistent regardless of clutch engagement... they're dependent only on engine RPM, it seems. That is, revving in neutral, clutch disengaged, or driving in any gear produces the same given amplitude at a given RPM. This is what...
thruthefence, I've added that to my list of things to mention to the shop technician. I can see this being possible with these people, now.
Rod, you raise good points. I had read many horror stories of slipping clutches occurring simply turning the flywheel on a lathe to resurface it on...
Tmoose, thank you for the wealth of considerations! I assume the install shop's technicians lacked the know-how or wherewithal to actually measure anything. From what the service manager indicated, it sounded like they were trying to find fault with the clutch/pressure plate (anything to deny...
Thanks thruthefence. No possibilities are ruled out, at this point, even after the shop pulled it back down "found nothing wrong" and put it back. Meanwhile, my driveline continues to vibrate, and I believe from the greatly increased clutch chatter that a damping spring has probably broken on...
Apologies for asking a possibly common flywheel question: my car forums of choice are vastly under-qualified to help. My question is twofold: How likely is it that a 23 lb (mild steel?) flywheel turned on a lathe (improper tool) or ground (proper tool) would become out of balance significantly...
