Checking the clearances in the mechanism of the valve drive mechanism motors Toyota 3-5 S-FE, 4S-Fi, 1-3, 4VZ-FE, 3S-GE and adjustment

Disconnect the negative wire from the battery, push it aside, except for its occasional contact with the negative terminal of the battery. Disconnect the cable system cruise control, air filter, channel and other elements that prevent the removal of the cap (lid) of the head unit. Remove the cover (s) of the head unit. To facilitate scrolling crankshaft unscrew the spark plugs. Place the number 1 piston at TDC on the compression stroke. Identify the gaps of these valves with a feeler gauge and fix the results of measurements that do not meet technical specifications. Gaps in the valve train, measured on a cold engine should meet the following quantities: For engines 3-5 S-FE, 4S-Fi, 1-3, 4VZ-FE clearances inlet. Valves - 0,19 - 0,29 mm, graduation. - 0,28 - 0,38 mm. For the 3S-GE engine valve clearances (inlet) - 0,15-0,25 mm, graduation. - 0,20 - 0,30 mm. Note: The four-cylinder engines, the piston of the first cylinder is at TDC compression stroke, it is possible to measure gaps exhaust valves 1 and 3 cylinders and the intake valves 1 and 2 cylinders. On the engines of V6, the first cylinder when the piston is at TDC on the compression stroke, you can measure the clearance of inlet valves 1 and 6, cylinders and exhaust 2 and 3 cylinders. At the 4-cylinder engines, turn to / shaft 360 degrees and re-align the setup tags. Measure the gaps remaining valves. Note: The four-cylinder engines, the piston 4-cylinder is at TDC on the compression stroke can be measured clearances exhaust valves 2 and 4 cylinders and the intake valves 3 and 4 cylinders. On V6 engines, such as turn the crankshaft at 240 degrees (2 / 3 of turnover), combine the installation label and measure the valve clearances (inlet), 2 and 3 cylinders and exhaust 4 and 5. Adjust the gap in the valve actuator. Remove the washer (the adjustment). Turn c / shaft so that the working projection, cam camshaft at the top. Using special tools, push the plunger, and place a spacer between the tappet and camshaft. Remove the special tools. Remove the washer (adjustment) using a small screwdriver and a magnetized rod. Calculate the size of the new washers (adjustment) as follows: Applying the mic, perform measurement of thickness removed washers and calculate the size of the new so that the clearance fit within the allowable values. Select the new washer (adjustment) with a thickness as close as possible to the calculated value, set it in the pusher. Using special tools, push the plunger, and remove the spacer. Measure the clearance in the valve train. Repeat for the other valve clearances which require adjustments. Replace the spark plugs. cover (s) head (s) of the cylinder block (do not use sealant, if the oil while the engine will trickle down, it is better to replace the rubber pads) and high-wire throttle cable bracket, etc. in the sequence, the reverse of removal.
