  Q: How to properly remove and install the harmonic balancer to ensure alignment and prevent engine damage on Mazda 6?

  A:

  To take off the harmonic balancer, make sure that both the crankshaft and timing sprocket are not loosened or it will put the engine out of time which will create serious damage. Start by taking out the drive belt and the right drive axle. Install the engine in line with the relevant locking tools. The crankshaft should not rotate when unscrewing the balancer bolt and as such, a special holding tool is needed that could be bought or made. Install the holding tool into the balancer and rotate the balancer bolt with a large wrench to make sure that the crankshaft is fixed with the holding tool. The next step is to unscrew the balancer bolt and then take off the balancer looking behind it and a diamond washer (behind the balancer) then replacing it with a new one (diamond washer) on the engines. To install, put a new diamond washer onto the crankshaft, spray the front seal a little with clean engine oil and fit the harmonic balancer. Install a new balancer bolt and washer with a hand tighten and position the hole at the top of the balancer in line with the timing chain cover. Aligning of the crankshaft is done using a crankshaft balancer alignment bolt, and then a balancer bolt is tightened to the required amount. Take out the timing pin, the camshaft alignment tool, the holding tool and alignment bolt. Turn the engine two full rotations clockwise, watching against resistance, which could be evidence of wrong valve timing. Once more rotate the engine to TDC, and fit the timing pin, and ensure the alignment with the crankshaft balancer aligning bolt. When this is not aligned, repeat the installation procedure up to the time the alignment has been done. After aligning, take out all the tools and bolts, put in the timing pin plug and put the components that have been taken out earlier.
