Heavy weight naturally slows down the movement of
any material. As you could have noticed, automobiles carrying more
cargo moves more steady even through rough roads than those that don’t
carry much. This is because the gravitational pull is stronger at such
point. The concept seems to have nothing wrong. But the mere fact that
the gravity is stronger with heavier materials, incorporating
additional equipments in a vehicle is not ideal, for that will affect
engine performance. Instead of utilizing that concept, auto makers use
harmonic balancers. As expected, Geo units also feature them.
Geo harmonic balancer is an auto component that acts as vibration
damper, eliminating uneasy movements. It’s a two-piece balancer
connected by rubber plugs, spring loaded friction discs, or both. This
auto product serves the vehicle by redirecting the twisting power
generated by the cylinder from the heavy part of the damper to the
rubber discs that connects the two parts of the damper. With that
concept, the twisting power hits the crankshaft instead, thus the
balancer is able to absorb the energy. But because the harmonic
balancer has heavy construction, the twisting energy finds a weaker
port which is the part with rubber material. The motion then speeds up
the damper wheel, making the crankshaft operation calm.
The harmonic balancer of your Geo should move in a standard speed. If
you notice some abnormality with its operation, most probably the
balancers are dislocated or damaged. When that happens, the
crankshaft’s performance will be affected, because the crank would also
run slow. This tells you to always ensure good condition of your Geo’s
harmonic balancers. If replacement is needed, make sure to get only the
high quality aftermarket Geo harmonic balancers. In such way decreased
torsional vibrations and prevention of crankshaft failure will be
ensured, so as prolonged engine life through reduction of wear on the
main bearing and main journals.
