If you are asking about timing gears with a belt system, you have to line the timing marks up with the marks on the gears. If you want to know about chain gear alignment please re-ask with vehicle specifics and I can answer that also.

Remove the valve cover and line up the timing marks on the crank and both cam gears. Now remove the crankshaft pulley and the timing cover. Insert a pin through each cam just behind the gears to hold them in position for reinstallation. Loosen the belt tensioner bolt and remove the belt. Now reinstall the new belt. I usually remove the pin from the exhaust cam and turn the crank counterclockwise to pull the slack to the tensioner side. Now tighten the tensioner bolt and turn the engine over a few times then line up the timing marks again. That will ensure proper belt alignment and cam timing.
A timing mark is usually a white line on the timing belt to sync the firing of cylinders in an engine. You can see this line when the engine is turned off or with a timing light also a strobe light when the engine is running.
If the timing belt broke you probably got some bent valves. but as for puting the timing belt back on, there are marks on the outer edge of the cam and a indention on the valve cover behind it. line those up and on the crank gear blade there is a small v. line that up with the triangle on the engine- around the 10 o'clock position. then you will have to commpress the tensioner and use a small Allen wrench to hold it compressed. then install the timing belt and put the tensioner back and pull the pin. spin it over by hand and make sure the marks line back up
THERE ARE SMALL HOLES IN THE TIMING GEARS THAT LINE UP WITH MARKS ON THE FRONT OF THE HEAD. When the crank pulley is at TDC on the compression stroke, 'E' & 'I' on the camshaft sprockets should be at 12 o'clock.
To line up the timing belt on a 1992 Dodge Spirit with a 2.5L engine, first ensure that the engine is at top dead center (TDC) on the compression stroke for cylinder one. Align the timing marks on the crankshaft and camshaft gears; the mark on the crankshaft should point to the 0° mark on the timing cover, and the camshaft gear should align with the pointer on the back cover. Once the marks are aligned, install the timing belt, ensuring it is taut on the tension side and has the correct tension. Finally, double-check the alignment before reassembling any components.
Line up the marks on the gears with the off colored links on the timing chain.
To set the timing gears on a 4HE1T engine, first, ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Align the timing marks on the camshaft and crankshaft gears; the marks should be in line with the designated reference points on the engine. After confirming the alignment, securely tighten the bolts and rotate the engine by hand to double-check the timing has not shifted. Always consult the specific service manual for torque specifications and detailed procedures.
For a 1984 Isuzu 2.3 engine, the timing marks are critical for proper alignment after a belt replacement. The crankshaft timing mark is typically located on the pulley and should align with a fixed pointer on the engine block. The camshaft timing mark is usually on the cam gear and should line up with a corresponding mark on the engine or timing cover. After replacing the belt, ensure both marks are aligned to maintain correct engine timing.
To adjust the timing take off the timing cover,take off belt and then line up the marks on the timing gear.You will need a special tool to hold the gears if it is a DOHC(duel over head cam)
there are 2 marks on the gears you have to line them up
