Mazda Harmonic Balancer

The Mazda Harmonic Balancer helps protect the crankshaft from twisting vibrations, which ensures smoother revs and longer engine life. Mazda has built its reputation on lively handling, efficient Skyactiv engines, and the striking Kodo soul of motion design that gives every model a sense of movement even when standing still, and i-Activsense safety tech and available all-wheel drive add confidence when roads turn rough. Mazda also investigates electric drive and mild hybrid systems to reduce fuel consumption, but it never forgets about the fun-to-drive feeling that has characterized the brand since the days of the rotary engine. Within this dynamic family, the Harmonic Balancer stands as an unseen guardian of performance, which, through a steel hub, a hefty inertia ring, and a resilient rubber layer, works to counteract combustion pulses before they shake the block. When the ring momentarily lags, opposing forces cancel and keep components spinning true and dashboards free of buzz. Because the design is tailored to the complete Mazda lineup as opposed to a single model, one quality Harmonic Balancer makes maintenance a rather simple affair across different engines while maintaining the smooth character that enthusiasts love. Timely replacement of this part prevents costly damage to the crankshaft, maintains quiet idle, and allows every Mazda driver to experience responsive acceleration mile after mile every day.

You'll get great performance and real durability when you pick genuine OEM Harmonic Balancer. Mazda builds these using high-quality materials and official factory methods to ensure they hold up mile after mile. You deserve that Mazda reliability without the headache of cheap knockoffs. It is easy to find exactly what you need in our huge inventory of genuine parts. Plus, every OEM part carries a real manufacturer's warranty for your peace of mind. You will love our low prices too. Order today and we will ship your brand-new parts fast. They often reach your door in just a few days.

Q: How to replace the crankshaft seal and harmonic balancer on Mazda 6?
A:
First, to remove the component, disconnect the cable with the negative battery terminal. Unscrew the lug nuts on the right front wheel, lift the front of the car and rest it safely on jackstands before taking off the wheel. Then unscrew the splash shield on the fender and unscrew the drivebelt. Grab the harmonic balancer with a two-pin spanner and loosen the retaining bolt before using a three-jaw puller to remove the harmonic balancer, making sure to use the correct adapter or it may be damaged. Cautiously lift the seal out of the timing chain cover using a seal puller, keeping the depth and rise of the seal in mind to install the new seal. Installation: To install, check the pulley surface and the front cover to confirm that the surface does not have any imperfections, rectify imperfections when needed. Apply clean engine oil on the new seal and then fit it with an appropriate seal driver with the lip facing inwards. On certain engines, pour RTV sealant in the keyway and inner bore of the pulley, lubricate the outer sealing surface and fit the pulley shortly after applying the sealant, positioning the keyway with the crankshaft key. Install the pulley bolt to the required torque, and it is advisable that a new pulley bolt is installed. Install the rest of the parts in that order, screw the lug nuts of the wheels, re-connect the battery and lastly start the engine to ensure that there is no oil leakage.
