|Since the last timing belt change ten days back I felt a "tingle" vibration in my
feet at 3000RPM. The vibration didn't lessen in the 1200 miles since
the work was performed so I had a suspicion that at least one of the
two balance shafts was out of sync. Today I disassembled the car to the
point of performing a timing belt change so that I could check, and if
needed, adjust all belt alignment items.
The timing belt (crankshaft to camshaft) alignment was suspect but after double-checks looks to be correct. The front balance shaft was off "one tooth". I hoped the back balance shaft would be in alignment once the front was changed, but no, the back was out a different amount.
These top photos document the final settings while two bottom photos show the out of spec balance shafts.
|With a 2am test drive complete I
know the 3000RPM tingle in my feet is gone. With the last photo taken
at 10:24pm it's taken me right about 3.5 hours to reassemble the
vehicle. One task scratched off my ToDo list.
