How do you adjust a harmonic balancer?
The only way to tighten the harmonic balancer bolt properly is to lock the motor up somehow and tighten it with a torque wrench to the correct tension. Which means usually wedging the flywheel some way. Or you could just use a impact wrench (rattle gun) and tighten it up really tight if you want the easy way out.
Where is top dead center on a harmonic balancer?
It is usually the largest pulley, often located in the center of the engine’s bottom end. Look for the timing marks on the pulley and the marker with which to line them up, usually located on the engine’s block or front cover.
How do you find the timing mark on a harmonic balancer?
Once Top Dead Center has bee found with a dial indicator or by other accurate means and have installed the harmonic with a timing tab, this calculator will determine your exact mark (in inches) at whatever degree you indicate in the data entry. Enter the number of inches for the diameter of your harmonic balancer.
Where is the harmonic balancer on the crankshaft?
The harmonic balancer is an accessory belt pulley and, although, is on the crankshaft, is not part of the valve timing. The valves are run by the timing chain behind the serpentine belt. What I need to know is if the sprocket on the crank for the timing chain is keyed, thus the valve timing would not be affected.
Why are there no alignment marks on my crankshaft?
This encoder ring was pushed off the back side of the harmonic balancer by the belt coming off the pulley and was spinning freely. I removed the harmonic balancer (which has no alignment keyway) and found that the encoder ring was not damaged but, is simply pressed into the pulley with no alignment marks either.
Why do you need a harmonic Mark calculator?
This calculator is designed to determine the measurement of an advanced (or retarded) degree setting on a harmonic balancer. If you determine TDC (Top Dead Center) and check the balancer, then you may utilize this calculator to provide the information to mark the exact degree setting you would like to use.

Where is the timing mark on a crankshaft?
Port timing is the degrees of crankshaft rotation after TDC to where port starts to open. Top Dead Center (TDC) is the top of the piston’s stroke and Bottom Dead Center (BDC) is the bottom of the piston’s stroke.
How is the crank angle measured in degrees?
The Crank Angle is the crankshaft rotation measured in degrees. There are 360 degrees total. Obviously, this is a very close approximation due to small inaccuracies on variable data input. Also please see our Port Height Above BDC Timing Calculator for two cycle engines and our Port Timing Duration Calculator, also for two cycle engines.
