How do I set timing on a 2.3 Suzuki aerio engine


wow no job stated.
04 (2.3L) ill take a wild guess and say, you might be fiddling the cam
and doing something there, new cam, new lifters, new chain, new head, ? what?
FSM means factory service manual, ever heard of one?

the FSM is just lousy 4 bucks why not read that first. and not mess it up.

https://suzukipitstopplus.com/Products/1004-2004-aerio-service-manual.aspx

you said SET, so i can only assume its all apart. right then
you want to Instal the chain and time it, right so here are the fsm steps
no photos. log in and read the FSM for that.
  1. Check that match mark on crankshaft timing sprocket is in match with timing mark on lower crankcase.
  2. Install crankshaft timing sprocket as shown in figure.
  3. Apply oil to bush of idler sprocket and install idler sprocket and sprocket shaft.
  4. Install first timing chain by aligning dark blue plate of first timing chain and match mark on idler sprocket.
  5. Bring yellow plate of first timing chain into match with match mark on crankshaft timing sprocket.
  6. Apply engine oil to sliding surface of timing chain tensioner and then install it as shown in figure. Tighten tensioner nut to 18 ft. lbs. (25 Nm).

Timing chain


It appears that you got it right but to be sure the check is on the timing chain there are 3 black links If you have it right then the black links will line up with the marks. If not then re adjust the gear that is not correct.- ensure that you have the ignition timing right as you may be 180 degrees out

On 2002 ford explorer,4.6-v-8, when i was changing timing chain guides and adjusters the chains jumped teeth on the crankshaft. The manual says the left camshaft timing mark should be approx. @ 11:oo & the...


Look for some Youtube videos on this repair. If I remember correctly the links on this chain have different color metal for the spots that the cam tooth goes against. When each side is in the proper tooth the right and left colored links will be on the cam mark and the crank mark should be on the timing TDC mark. Sounds like the slack you describe is wrong and a tooth is off because the tensioner is allowing slack.. You need to slip a tooth one way or the other until the tensioner has room to be in a neutral position.

Timing chain replacement


Timing Chain and Gears REMOVAL & INSTALLATION 1.9L Engine NOTE: The following procedure requires the use of the puller tool No. J-25031 or equivalent, and timing sprocket installation tool No. J-26587 or equivalent.
  1. Remove the timing (front) cover from the engine.
  2. Lock the shoe on the automatic adjuster in fully retracted position by depressing the adjuster lock lever. NOTE: To remove the timing chain, it may be necessary to remove the camshaft sprocket. Before removing the timing chain, be sure to align the timing marks.
  3. Remove timing chain from crankshaft sprocket.
  4. Check the timing sprockets for wear or damage. If crankshaft sprocket must be replaced, remove the sprocket and the pinion gear from crankshaft using the puller tool No. J-25031 or equivalent.
  5. Check timing chain for wear or damage; replace as necessary. Measure distance "L'' (40 links) with the chain stretched with a pull of approximately 22 lbs. (98N). Standard "L'' value is 15 in. (381mm); replace chain if "L'' is greater than 15.16 in. (385mm).
  6. Remove the automatic chain adjuster-to-engine bolt and the adjuster.
  7. To check the operation of the automatic chain adjuster, push the shoe inwards, if it becomes locked, the adjuster is working properly. The adjuster assembly must be replaced if rack teeth are found to be worn excessively.
  8. To remove the chain tensioner, remove the "E'' clip and the tensioner. Check the tensioner for wear or damage; if necessary, replace it. Fig. 1: Timing chain guide and tensioner - 1.9L engine 85383285.gif

  9. Inspect the tensioner pin for wear or damage. If replacement is necessary, remove the pin from the cylinder block using a pair of locking pliers. Lubricate the NEW pin tensioner with clean engine oil. Start the pin into block, then place the tensioner over the appropriate pin. Position the E-clip onto the pin, then (using a hammer) tap it into the block until clip just clears tensioner. Check the tensioner and adjuster for freedom of rotation on the pins.
  10. Inspect the guide for wear or damage and plugged lower oil jet. If replacement or cleaning is necessary, remove the guide bolts, the guide and the oil jet. Install a new guide and upper attaching bolt. Install the lower oil jet and bolt, so that the oil port is pointed toward crankshaft. To install: Fig. 2: Timing chain alignment and installation - 1.9L engine 85383286.gif
    Fig. 3: Inspecting the timing chain for wear 85383287.gif

  11. Install the timing sprocket and the pinion gear (groove-side toward the front cover). Align the key groove with crankshaft key, then drive it into position using installation tool No. J-26587 or equivalent.
  12. Turn the crankshaft so that key is turned toward the cylinder head-side (No. 1 and No. 4 pistons at TDC).
  13. Install the timing chain, align the timing chain mark plate with the mark on the crankshaft timing sprocket. The side of the chain with the mark plate is on the front-side and the side of chain with the most links between mark plates is on the chain guide-side. Keep the timing chain engaged with the camshaft timing sprocket until the camshaft timing sprocket is installed on the camshaft.
  14. Install the camshaft timing sprocket so that it's marked-side faces forward and it's triangular mark aligns with the chain mark plate.
  15. Install the automatic chain adjuster.
  16. Release the lock by depressing the shoe on adjuster by hand, and check to make certain the chain is properly tensioned when the lock is released.
  17. Install the timing cover assembly.

If the timing chain/belt is to be reused, mark the direction of rotation on the timing chain/belt.

19. Loosen the timing chain/belt tensioner nut.

  1. Remove the timing chain/belt.
Installation
NOTE: Ensure that the timing marks on the camshaft sprockets (6256) and the seal plate are properly aligned. Ensure that the timing marks on the crankshaft sprocket and the oil pump housing are still aligned.



stv~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Pay special attention to the tooth shape of the timing belt. The current timing belts are not interchangeable with the timing belts from the 1993 model year. The 1993 model year uses a square or trapezoidal tooth timing belt while the current model year uses a rounded tooth design. The design change was made to extend the service life of the timing belt from 60,000 miles for the square or trapezoidal toothed belt to 105,000 miles for the rounded tooth belt. If the proper timing belt is not used, the customer may complain of a "whining" noise coming from the engine compartment. If the camshaft sprocket has a square cut in the valley of the gear tooth, it will require a square or trapezoidal tooth timing belt. If the camshaft sprocket has a rounded cut in the valley of the gear tooth, it will require a rounded tooth timing belt.
NOTE: If a new timing chain/belt is to be installed, make sure that the arrow is pointing away from the engine. If a timing chain/belt is to be reused, make sure that the directional arrow that was marked during disassembly is facing the correct direction.

NOTE: A new timing chain/belt has three white timing marks that indicate the correct timing positions of the camshafts and the crankshaft. These marks will help ensure that the engine (6007) is timed properly. When the engine is properly timed each white timing mark on the timing chain/belt will be aligned with the corresponding camshaft and crankshaft timing mark on the sprocket. Because the white timing marks are not evenly spaced you will need to refer to the following illustration for proper timing chain/belt placement. There should be 40 timing belt teeth between the timing marks of the front and rear camshaft sprockets and 43 teeth between the timing mark on the front camshaft sprocket and the timing mark on the crankshaft sprocket.

NOTE: Verify that the camshaft timing marks are aligned with the timing marks on the seal plate, and that the crankshaft sprocket timing mark is aligned with the timing mark on the oil pump (6600).

Install the timing chain/belt starting at the crankshaft sprocket and moving around to the camshaft sprockets following a counterclockwise path. Do not allow any slack in the timing chain/belt between the timing sprockets. After all of the timing marks are matched up with the timing chain/belt installed, slip the timing chain/belt onto the timing chain/belt tensioner.

  1. While holding the timing chain/belt tensioner with an Allen wrench, loosen the timing chain/belt tensioner nut.
  1. Allow the timing chain/belt tensioner to put pressure on the timing chain/belt.
  1. Use an Allen wrench to turn the timing chain/belt tensioner 70-80 degrees clockwise and tighten the timing chain/belt tensioner nut to 43-58 Nm (32-43 lb-ft).

    1. Rotate the crankshaft (6303) clockwise twice and align the No. 1 piston to Top Dead Center (TDC) on its compression stroke.
    1. Apply 98N (22 lbs) of force on the timing chain/belt between the rear camshaft sprocket and the timing chain/belt tensioner.
    2. NOTE: An assistant may be needed to adjust the timing chain/belt.

      While holding the timing chain/belt tensioner steady with an Allen wrench, loosen the timing chain/belt tensioner nut. Remove the Allen wrench and adjust the timing chain/belt tensioner as follows:
      1. Install a 0.35mm (0.0138 inch) thick and 12.7mm (0.500 inch) wide feeler gauge as shown.

  1. Turn the crankshaft clockwise to position the feeler gauge between the timing chain/belt tensioner and the timing chain/belt

  1. Tighten the timing chain/belt tensioner nut to 43-58 Nm (32-43 lb-ft).
  1. Turn the crankshaft clockwise to remove the feeler gauge from between the timing chain/belt tensioner and the timing chain/belt.
  1. Rotate the crankshaft clockwise twice and align the No. 1 piston to TDC on its compression stroke.
  1. Apply 98N (22 lbs) of force on the timing chain/belt between the rear and front camshaft sprocket.
    1. Measure the timing chain/belt deflection. Timing chain/belt deflection should be between 13-15mm (0.51-0.59 inch). If timing chain/belt deflection is not within specification, repeat steps 3-11. If the timing chain/belt cannot be adjusted to within specification, the timing chain/belt will have to be replaced.
    1. Position the lower engine front cover and install the five lower engine front cover bolts. Tighten the five lower engine front cover bolts to 3-5 Nm (27-44 lb-in).
    1. Install the outer timing chain/belt guide and the crankshaft pulley. Refer to the procedure in this section.
    1. Position the water pump pulley on the water pump and install the four water pump pulley bolts
    1. Use Strap Wrench D85L-6000-A or equivalent to hold the water pump pulley, and tighten the four water pump pulley bolts to 16-21 Nm (12-15 lb-ft).
    1. Position the RH outer engine and transmission splash shield and install the four RH outer engine and transmission splash shield bolts and two screws.
    1. Install the RH front wheel and tire assembly. Tighten the lug nuts (1012) to 98-118 Nm (72-87 lb-ft).
