Advice needed - timing chain

[AussieinNC]

The balancer is keyed to the crankshaft....if it moved during tightening the crank would have moved as well.

The outer ring of the balancers sometimes rotates around a little.

If you want to ensure the timing tab and balancer marks line up correctly you can do a positive stop procedure to index a new line on the balancer.

Purchase yourself a positive stop tool (amazon has them cheap). https://www.amazon.com/ZFLXH-Univers...s%2C101&sr=8-2

Set your engine to what you believe is TDC on cylinder 1 on compression. Look for the vales on cylinder 6 to have exhaust just closing and intake just opening. This is known as overlap.

The tool goes into the number 1 spark plug hole but first turn the crank backwards about half a turn. Screw in the stop tool and very slowly, manually turn the crank clockwise until the stop tool prevents any further crank movement. Take a white marker and mark a line on the balancer at the 0 degree mark on the tab. Now rotate the crank BACKWARDS slowly until you feel it stop again and mark a white line on the balancer. Remove the stop tool and turn the crank clockwise until you can see the two white lines. Measure the distance around the balancer using a tape and make a mark on the balancer at the mid point of the distance. This mark is now your true TDC mark and should be used for timing purposes. Remove the other marks. Take a small file and scribe a heavy line across the edge of the balancer then fill it with white permanent paint.
