The uneasy movements and vibrations experienced in your Subaru while running is normal. Engine performance and operation of all other systems are the main causes, as well as road irregularities. But if it is producing too much vibration and involuntary movements, something’s not right with the Subaru harmonic balancers. They could either be damaged or dislocated.
Harmonic balancer is 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.
Subaru harmonic balancers are the vehicle’s components which act as vibration dampers. When they are damaged, dislocated or not properly installed, you’d feel like you’re riding a horse instead of a sophisticated automobile. In conditions such as this, the operation of the crankshaft will become slow. The effect on the movement of the vehicle could be somehow tolerated. But if the condition continues, the defect in the crankshaft performance will progress and possibly cost you other vital engine parts.
If anything is noticed to be working badly, we are advised to conduct an auto checkup or bring the machine to expert machinists in order to identify what the problem really is. Early detection of the problem will spare the other vital parts from also getting damaged. Torsional vibrations will be decreased, crankshaft failure will be prevented, and prolonged engine life through reduction of wear on the main bearing and main journals is ensured. Moreover, you won’t have to spend more money for additional repair and replacement costs.
