Does anyone know if these are balanced at the factory as one unit (crank/pulley/flywheel) or if they are just balanced individually and assembled? Theres plenty of people saying either way so I'm looking for someone who actually knows for sure, but people with facts are hard to find.
Unfortunately, I do not have a definite answer to your question and knowing Toyota's reluctance to share information on manufacturing and assembly methods, I doubt if you will get one.
I am somewhat familiar with Toyota's vehicle assembly methods and assuming that the same processes are applied to powertrain assembly, my guess is that each of those components are balanced individually and then assembled in order to speed up the actual assembly process. I know that each engine is run in prior to shipping to vehicle assembly locations.
OK, thanks Ray - thats about as close as an answer as ive found anywhere and it confirms my thoughts too so I'll say youre right ;-)
Cheers J
