Hello, Finding top dead center is not that hard. All you will need to do is remove spark plug for cylinder number one. With a long screw driver, place it into cylinder. Turn the crank bolt and you will see screw driver move up or down ( keep one hand on screw driver, and keep it straight, or it could get stuck ) you can watch it come all the way up, to find top dead center. Double check the crank, timing marks should also be visible.
If you have any more questions on this, please feel free to ask. Thanks
Yes you can remove the crank balancer. After you removed it you can use the crank bolt and washer, and find another some what thick washer. You can put that bolt back on to help align the timing marks.
Remember you are going to need another thick washer with the crank bolt. Failure to do that can crack the tip of the crank. It's just to make up the gap difference with out the balancer
