Looking at the engine from the front, the normal movement of the crankshaft is clockwise rotation.
Warning: before starting work, place the gearbox in neutral and turn off the ignition system - to do this, remove the ignition coil wire from the distributor cap and ground it.
A) The preferred method is to rotate the crankshaft using a large socket and wrench connected to a large bolt screwed into the crankshaft.
b) You can also use an additional starter switch, this will save time Connect the wires to the starter coil leading to terminals S 9 (switch) and B (battery). When the piston is close to TDC position, use the wrench and socket as above.
V) If your assistant is able to intermittently turn on the ignition, then the piston will go to TDC without using an additional starter switch. To complete the procedure, use a socket wrench as described in subparagraph a).
2. Locate the No. 1 spark plug wire terminal in the distributor cap, then mark the distributor base under the terminal or opposite the terminal.
3. Remove the distributor cap as described in chapter 1.
4. Turn the crankshaft (see paragraph 1 above), while the ignition timing indicating TDC (usually zero or T), will not match the pointer (see drawing).
5. At this point, the rotor will point to the mark you made earlier. If it is rotated 180 degrees, then the piston is at TDC on the exhaust stroke.
6. If the cylinder was in the exhaust stroke, turn the crankshaft clockwise one full revolution (360 degrees). Then the rotor will accurately point to the mark. If the rotor points to the #1 spark plug wire terminal located on the distributor cap (it is marked with a label on the distributor housing or engine) and the ignition timing coincides with it, which means that the number 1 piston is at TDC on the compression stroke.
7. After piston No. 1 is brought to TDC on the compression stroke, for the remaining cylinders, they are obtained by turning the crankshaft and following the ignition order (see picture).
