2. Piston installation (pistons) to the TDC position is an essential part of many procedures, such as removing the camshaft, timing chain and sprocket.
3. Remove the spark plugs (see chapter 1, section 32).
4. Place the automatic transmission in park and chock the rear wheels of the vehicle. Raise the front of the vehicle and secure it to stands.
5. Looking at the engine from the drive belt side, the normal rotation of the crankshaft is clockwise rotation. To set any piston to the TDC position, it is necessary to turn the crankshaft with a socket wrench with a ratchet (ratchet) for a bolt screwed into the center of the antivibrator on the crankshaft.
6. Have a helper turn the crankshaft with a ratchet wrench as described above while holding your finger over the spark plug hole of cylinder 1 (see illustration).
3.6. Hold your finger over the spark plug hole until you feel air coming out
Note. To find the location of the 1st cylinder, see the figure in the section "Technical data" in this chapter.
7. When the piston approaches TDC, air pressure will be felt at the spark plug hole. Have your assistant turn the crankshaft slowly.
8. Insert the plastic handle into the spark plug hole (see illustration). As the piston rises, the handle will begin to push out. Pay attention to the point when the handle stops - this is the TDC.
3.8. Insert a plastic handle into the spark plug hole to detect piston movement
9. After the 1st cylinder is set to TDC on the compression stroke, the top dead centers for the remaining pistons can be found by turning the crankshaft clockwise by 120°in accordance with the order of operation of the cylinders, or you can repeat steps 6-8, to find the TDC for each particular cylinder.
