The timing installation method of the new Santana is as follows:
(1) Use a spark plug sleeve to remove all spark plugs.
(2) Look through the spark plug hole and use a manual wrench or sleeve to turn the crankshaft pulley fixing bolt {Note: The crankshaft can only be turned in the normal rotation direction of the engine crankshaft). Bring the piston of cylinder 1 close to top dead center. Remove the blind plug bolt located approximately 5 cm directly behind the crankshaft position sensor (CKP). Install and tighten Special Tool No. 2 directly by hand. Turn the crankshaft clockwise again (the direction in which the engine crankshaft normally rotates) so that the crankshaft of the crankshaft is in contact with the No. 2 special tool, and then turn the crankshaft counterclockwise about 30° - 60°.
(3) Use a hand tool to gently turn the intake and exhaust camshafts. Make the intake and exhaust cams of cylinder 1 be in the position where the intake and exhaust valves are all closed (which is commonly known as the "upper figure"), and then insert the No. 1 special tool from the rear plane of the cylinder head tightly into the intake cam. In the timing groove of the exhaust camshaft.
(4) Use the tool again to rotate the crankshaft pulley fixing bolt in the direction of normal rotation of the engine crankshaft, so that the crankshaft is in close contact with the No. 2 special tool.
(5) Remove the crankshaft pulley fixing bolt (do not rotate the crankshaft), remove the crankshaft pulley, find an M6x18 bolt, and tighten the bolt by hand. Fix the crankshaft pulley to the timing cover of the engine (note: the fixing bolts can be tightened by hand. Do not tighten with tools. In addition, there is a bolt hole for M6 bolts on the crankshaft pulley. You need to tighten it when fixing. The crankshaft pulley points vertically downward and aligns with the bolt hole on the timing cover,).
(6) Use a special tool or the same tool to secure the crankshaft pulley in reverse, and gently fix and lock the crankshaft pulley fixing bolts, and then remove the M6x18 bolts that position the crankshaft pulley. It should be noted that the crankshaft pulley fixing bolt must be locked in two stages: use a torque wrench to tighten to 100 N.m; use an angle ruler and a torque wrench to tighten the bolt to 90°;.
(7) Disassembly special tool 205-072.
(8) Disassembly special tools 2.
(9) Use a tool to rotate the crankshaft about 1.75 turns in the normal engine running direction. At this time, the piston of cylinder 1 is approximately 450 degrees before TDC (top dead center).
(10) Install special tool 2 again.
(11) Use a tool to rotate the crankshaft to cylinder 1 TDC (top dead center) according to the normal rotation direction of the crankshaft, so that the crankshaft of the engine crankshaft is in close contact with the special tool 2, and then check the small holes on the crankshaft pulley. Check whether the bolt holes are directly below and aligned with the threads of the timing cover, and tighten the M6x18 bolts by hand.
(12) Use special tool 1 to check whether the timing position of the intake and exhaust camshafts is normal and whether the tool can be placed well into the timing slot of the intake and exhaust camshafts. If it doesn't fit nicely into the slot, the timing will need to be rematched.
(13) If it can be put into the groove of the camshaft well, remove the camshaft timing matching special tool.
(14) Remove the M6x18 bolt for positioning the crankshaft pulley.
(15) Special tools for disassembly 2.
(16) Use tools to tighten the blind plug bolts according to the standard torque (plus N.m).
(17) Use the calibration tool to calibrate and install the engine crankshaft position sensor.
(18) Install the CKP sensor fixing bolt according to the standard torque, and remove the crankshaft position sensor calibration tool. At this point, the engine valve timing correction work is completed.
