If you want a picture of one of the fig, let me know which one, there are several pictures. All I'm doing is copying out of my database.

Would need to see type of engine and a good look ,does it have any marks on front of engine ? if not then crank mark will be through a hole in bellhousing ,injector pump if common rail will have no marks as not needed to be timed in ,camshaft if no holie in spoke on gearwheel tand no mark on rim then remove the rocker cover and look on back of camshaft for a slot ?but no year mentioned here so ?? why didnt you put some white paint marks on gears before you took it apart

REMOVAL & INSTALLATION

4.3L, 5.0L, 5.7L and 7.4L Engines
See Figures 1, 2, 3, 4, 5 and 6

1. Remove the timing cover. This will allow access to the timing chain.
2. Crank the engine until the timing marks on both sprockets are nearest each other and in line between the shaft centers.

Fig. Fig. 1: Crank the engine until the timing marks on both sprockets are in line

1. On 1996-98 vehicles remove the crankshaft position sensor reluctor ring, if equipped. On 7.4L engines tool J-41371 or its equivalent puller must be used to remove the reluctor ring.
2. Take out the bolts that hold the camshaft gear to the camshaft. This gear is a light press fit on the camshaft and will come off easily. It is located by a dowel. The chain comes off with the camshaft gear.

Fig. Fig. 2: Remove the camshaft gear retaining bolts

Fig. Fig. 3: Remove the camshaft gear and timing chain
A gear puller will be required to remove the crankshaft gear.
To install:

1. Without disturbing the position of the engine, mount the new crankshaft gear on the shaft, and mount the chain over the camshaft gear. Arrange the camshaft gear in such a way that the timing marks will line up between the shaft centers and the camshaft locating dowel will enter the dowel hole in the cam sprocket.
2. Place the cam sprocket, with its chain mounted over it, in position on the front of the truck and pull up with the three bolts that hold it to the camshaft.
3. After the gears are in place, turn the engine two full revolutions to make certain that the timing marks are in correct alignment between the shaft centers. Tighten the camshaft sprocket bolts (and nut on the 4.3L) to 21 ft. lbs. (28 Nm) on 1988-95 models. On 1996-98 models, tighten the bolts to 18 ft. Lbs. (25 Nm). On the 7.4L, tighten them to 20 ft. lbs. (26 Nm) on 1988-95 models. On 1996-98 models, tighten the bolts to 25 ft. Lbs. (34 Nm).

When installing the crankshaft position sensor you must use install a new oil ring seal onto the sensor.

1. Install the crankshaft position sensor reluctor ring (if equipped), onto the crankshaft until it is firmly seated against the crankshaft sprocket. On 1996-98 7.4L vehicles replace the reluctor ring with a new component.
2. Install the front cover, torsional damper, water pump and the radiator.

Fig. Fig. 4: A gear puller will be required to remove the crankshaft gear

Fig. Fig. 5: Timing mark alignment-4.3L, 5.0L, 5.7L and 7.4L engines

It is normal to have to set the timing marks a couple of times before you can say they are right. If at first they don't pass the 2 turn roll around, then redo it. By the third time, you will have it right, and when you close it up, you will know its right. The car will start and you will be good for it. Patience. close isn't good enough.

you will need to refer to car repaire manual to set the marks to its factory standard both on camshaft and crank shaft.

1. Drain the cooling system and remove the front cover.
   

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

1. Crank the engine until the timing marks on the camshaft and crankshaft gears are aligned.
   
2. Use a gear puller to removal both of the timing gears.
   
3. Before installing the timing gears, be sure that the key and spacer are properly installed. Align the gear key way with the key and install the gear on the camshaft. Be sure that the timing marks line up on the camshaft and the crankshaft gears and install the crankshaft gear.
   
4. Install the front cover, and assemble the rest of the engine in the reverse order of disassembly. Fill the cooling system.
   

Timing belt removed, static timing was not set before removing timing belt.

[Set Static Timing:
No.1 piston is brought up to TDC before removing timing belt.

Cam gear has a punchmark on face of gear, and this mark aligns with one single tooth. There is a matching punchmark on the Timing Belt Rear Upper Cover.

Facing the cam gear, the mark is to the upper right. There is an 'egg shape' of the timing belt upper rear cover, in this spot. This punchmark is in that 'egg shape', and is close to a bolt hole. The cam gear mark lines up with the Timing Belt Rear Upper Cover, mark.

The crankshaft gear has a punchmark on the face. It lines up with one single tooth. There is a corresponding punchmark on the lower right side. An alignment mark)

Should be a round punchmark on the face of the crankshaft gear. It lines up with a single tooth. Wipe the gear clean, use a little carb cleaner. (NO flames, or sparks nearby, well ventilated area)

Barring you cannot find the crankshaft mark, find the camshaft alignment marks, make sure they are aligned with the alignment, (Punchmark), on the Timing Upper Rear Cover.

Count the teeth in the timing belt. There should be 133 teeth on the belt.

There is 43 teeth in-between the timing mark of the camshaft, and the timing mark on the crankshaft.

(43 teeth in-between the Right Side Camshaft mark to crankshaft mark, 43 teeth in-between the Left Side Camshaft mark to crankshaft mark)

There should be 40 teeth in-between the two cam gears.
