Description
This new harmonic balancer from the 3.4 engine replaces the
2.8 harmonic balancer on the Fiero engine. The 2.8 harmonic balancer is no
longer available anywhere else. This balancer is exactly the same as the 2.8
except that the timing marks are not in the correct position. We inscribe a new
timing mark on the balancer in the correct location and inscribe a TDC marking
to avoid confusion with the other marks. Attempting to copy the timing mark
from the old balancer is not recommended. The old balancer outer ring becomes
detached from the inner ring due to age, causing the timing mark to shift. This
makes the proper spark timing of the engine incorrect. This happens more
frequently as engines get older
