Attention! It is understood that the work is carried out with the correct installation of the ignition distributor (if a distributor is provided).
Attention! If it is necessary to restore the correct position of the distributor, then determine the engine stroke by the feeling of compression in the 1st cylinder with the candle turned out, then align the ignition timing marks (see below).
Attention! The installation procedure is the same for 2F, 3F-E and 1FZ-FE twin shaft OHV engines.
1. Installing the piston of the 1st cylinder at the TDC of the compression stroke is necessary to perform adjustment and adjustment work (valve adjustment, ignition timing, etc.).
2. Move the transmission selector to Neutral or Park (on automatic transmission) or in neutral (on a manual transmission). Get the central high-voltage wire of the distributor of ignition and connect with weight.
3. The crankshaft is turned with a key by the head of the pulley bolt clockwise.
4. On the wire from the spark plug of the 1st cylinder, find the corresponding terminal on the cover of the ignition distributor and mark it with a risk on the body. Remove the distributor cap.
5. Turn the crankshaft with a wrench on the head of the pulley bolt clockwise until the marks on the flywheel are aligned (torque converter drive plate) with pointer (on engines 2F and 3F-E, photo on the left) or grooves on the crankshaft pulley with a mark "0" on a fixed scale (on engines 1FZ-FE, photo on the right).
6. If the pointer of the distributor slider is opposite the risks on the distributor housing, then the piston of the 1st cylinder is at TDC of the compression stroke. If the slider is turned 180°from the risks, then turn the crankshaft 1 turn, after which the piston of the 1st cylinder will be set to the TDC of the compression stroke. In this case, the marks on the scale and the pulley must be aligned, and the slider pointer must be opposite the risk, indicating the output of the 1st cylinder.
Attention! If it is not possible to set the piston of the 1st cylinder to the TDC of the compression stroke in this way, then the reasons are the incorrect installation of the ignition distributor, gears or the camshaft drive circuit.
7. Designate the terminals of other wires in accordance with the order of operation of the engine. By turning the crankshaft further clockwise relative to the TDC position of the 1st cylinder, you can set the piston of each cylinder to TDC, aligning the slider with the pin marks.
