I removed the engine balancer without making any marks , i am now ready to install it but i don't know what is its position since i cant find any marks on the balancer shaft nor its housing.

Take out the #1 spark plug and turn the engine by hand until you feel compression building when your thumb is over the spark plug hole. Now continue turning the engine slowly while watching for the timing mark on the dynamic balancer line up with the TDC mark on the timing indicator. Position the distributor so that the rotor is pointing to the #1 plug wire position on the rotor cap. When you mesh it with the cam gear, it will move past the #1 position. Take it back out and move the rotor to compensate for the distance it moves when the distributor is fully seated. Install the base clamp and bolt but don't tighten the bolt yet. Make the engine ready to run. Hook up a timing light and start the engine and set the timing by rotating the distributor until the timing marks are correct, then tighten the clamp bolt.

If you are referring to the ignition timing, the you connect the timing light into the no 1 spark plug lead. Start the engine and shine the light - which should be flashing - at the front of the engine onto the harmonic balancer. You should be able to see the timing mark on the harmonic balancer, and the scale on the engine you align it to. It may help to mark the harmonic balancer with a small dot of white paint to make it more visible. Adjust the distributor so that the timing mark on the harmonic balancer aligns with the timing mark on the block that the manual tells you to use. Make sure that the idle speed is correct first. However if you have not removed the distributor, then the ignition timing should still be OK. If you are referring to the timing of the camshafts and gears, then you do not use a timing light. Most vehicles have special tools that are installed onto the camshafts and crankshaft which lock them into the correct position so that the timing is correct. If you have replaced all these parts and do not know how to set the timing of them, get help from a mechanic otherwise you will break you engine when you try to start it.

2.2L & 2.3L Engines
Except S2000 with 2.2L Engine

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Remove the cylinder head (valve) and upper timing belt covers.
3. Turn the engine to align the timing marks and set cylinder No. 1 to Top Dead Center (TDC). The white mark on the crankshaft sprocket should align with the pointer on the timing belt cover. The words UP embossed on the camshaft sprocket should be aligned in the upward position. The marks on the edge of the sprocket should be aligned with the cylinder head or the back cover upper edge. Once in this position, the engine must NOT be turned or disturbed.
4. Remove all necessary components for access to the lower timing belt cover, then remove the cover.
5. There are two belts in this system; the one running to the camshaft sprocket is the timing belt. The other, shorter one drives the balance shaft and is referred to as the balancer shaft belt or timing balancer belt. Lock the timing belt adjuster in position, by installing one of the lower timing belt cover bolts to the adjuster arm.
6. Loosen the timing belt and balancer shafts tensioner adjuster nut, do not loosen the nut more than one turn. Push the tensioner for the balancer belt away from the belt to relieve the tension. Hold the tensioner and tighten the adjusting nut to hold the tensioner in place.
7. Carefully remove the balancer belt. Do not crimp or bend the belt; protect it from contact with oil or coolant.
8. Remove the balancer belt sprocket from the crankshaft.
9. Loosen the lockbolt installed to the timing belt adjuster and loosen the adjusting nut. Push the timing belt adjuster to remove the tension on the timing belt, then tighten the adjuster nut.
10. Remove the timing belt by sliding it off the sprockets. Do not crimp or bend the belt; protect it from contact with oil or coolant.
11. If defective, remove the belt tensioners by performing the following:
    1. Remove the springs from the balancer belt and the timing belt tensioners.
    2. Remove the adjusting nut from the belt tensioners.
    3. Remove the bolt from the balancer belt adjuster lever, and then remove the lever and the tensioner pulley.
    4. Remove the lockbolt from the timing belt tensioner lever, then remove the tensioner pulley and lever from the engine.
12. This is an excellent time to check or replace the water pump. Even if the timing belt is only being replaced as part of a good maintenance schedule, consider replacing the pump at the same time.
13. To install:
14. 1. If the water pump is to be replaced, install a new O-ring and make certain it is properly seated. Install the water pump and tighten the mounting bolts to 106 inch lbs. (12 Nm).
    2. If the tensioners were removed, perform the following procedures:
       1. Install the timing belt tensioner lever and the tensioner pulley.
       2. Install the balancer belt pulley and adjuster lever.
       3. Install the adjusting nut and the bolt to the balancer belt adjuster lever.
       4. Install the springs to the tensioners.
       5. Install the lockbolt to the timing belt tensioner, then move it its full deflection and tighten the lockbolt.
       6. Move the balancer it's full deflection and tighten the adjusting nut to hold its position.
    3. The pointer on the crankshaft sprocket should be aligned with the pointer on the oil pump; the camshaft sprocket must be aligned so that the wordUP is at the top of the sprocket and the marks on the edge of the sprocket are aligned with the surfaces of the head or the back cover upper edge.
    4. Install the timing belt on the sprockets in the following sequence: crankshaft sprocket, tensioner sprocket, water pump sprocket and camshaft sprocket.
    5. Check the timing marks to be sure that they did not move.
    6. Loosen, then retighten the timing belt adjusting nut; this will apply the proper amount of tension to the timing belt.
    7. Install the timing balancer belt drive sprocket and the lower timing belt cover.
    8. Install the crankshaft pulley and bolt, tighten the bolt to 181 ft. lbs. (245 Nm). Rotate the crankshaft sprocket 5-6 turns to position the timing belt on the sprockets.
    9. Set the No. 1 cylinder to TDC and loosen the timing belt adjusting nut one turn. Turn the crankshaft counterclockwise until the cam sprocket has moved 3 teeth; this creates tension on the timing belt.
    10. Tighten the timing belt adjusting nut.
    11. Set the crankshaft sprocket and the camshaft sprocket to TDC. If the sprockets do not align, remove the belt to realign the marks, then install the belt.
    12. Remove the crankshaft pulley and the lower cover.
    13. With the timing marks aligned, lock the timing belt adjuster in place with one of the lower cover mounting bolts.
    14. Loosen the adjusting nut and ensure the timing balancer belt adjuster moves freely.
    15. Align the rear timing balancer sprocket using a 6 x 100mm bolt or rod. Mark the bolt or rod at a point 2.9 in. (74mm) from the end. Remove the bolt from the maintenance hole on the side of the block; insert the bolt/rod into the hole and align the 2.9 in. (74mm) mark with the face of the hole. This will hold the shaft in place during installation.
    16. Align the groove on the front balancer shaft sprocket with the pointer on the oil pump.
    17. Install the balancer belt. Once the belts are in place, be sure that all the engine alignment marks are still correct. If not, remove the belts, realign the engine and reinstall the belts. Once the belts are properly installed, slowly loosen the adjusting nut, allowing the tensioner to move against the belt. Remove the bolt from the maintenance hole and reinstall the bolt and washer.
    18. Install the crankshaft pulley, then turn the crankshaft sprocket 1 turn counterclockwise and tighten the timing belt adjusting nut to 33 ft. lbs. (45 Nm).
    19. Remove the crankshaft pulley and the bolt locking the timing belt adjuster in place.
    20. Install the lower and upper timing belt covers, and all applicable components. When installing the crankshaft pulley, coat the threads and seating face of the pulley bolt with engine oil, then install and tighten the bolt to 181 ft. lbs. (250 Nm).
    21. Install the cylinder head cover gasket cover to the groove of the cylinder head cover. Before installing the gasket thoroughly clean the seal and the groove. Seat the recesses for the camshaft first, then work it into the groove around the outside edges. Be sure the gasket is seated securely in the corners of the recesses.
    22. Apply liquid gasket to the four corners of the recesses of the cylinder head cover gasket. Do not install the parts if 5 minutes or more have elapsed since applying liquid gasket. After assembly, wait at least 20 minutes before filling the engine with oil.
    23. Install the cylinder head (valve) cover and all other applicable components.

Set the engine to the number one compression,and bring the timing mark to zero on the harmonic balancer.(or just bring the timing on the harmonic to zero). mark to match the plug wires to cap,remove the cap.(if you can remove the cap without removing plug wire) mark the rotor position to the engine using a scribe, mark the rotor to the distributor, mark the distributor to the engine using a scribe,Take the lock down bolt out and pull out distributor. when you reinstall line up all your marking and check timing.

when you install the distributor the rotor button should point at the # 1 plug wire on the distributor cap make sure you are on the compression stroke of the motor when doing this you can verify that you are on the compression stroke by removing the #1 spark plug and turning the engine over while holding your fingure over the spark plug hole it will push your finger off the hole you need to spin the engine .spin the engine over slow while doing this so you don,t pass the timing mark on the harmonic balancer.

1. Disconnect the negative battery cable.
2. Turn the engine to align the timing marks and set cylinder No. 1 to TDC on the compression stroke. Once in this position, the engine must NOT be turned or disturbed. On DOHC Preludes without VTEC, hold each of the camshafts in the TDC position by inserting 5mm diameter punches into the alignment holes just behind each cam pulley.
3. Remove the splash shield from below the engine.
4. Drain the engine coolant. Use a clean container; cap or cover the container and wipe up spillage.
5. Unplug the electrical connector at the cruise control actuator, then remove the actuator. Don't disconnect the cable; simply move the actuator out of the work area.
6. Remove the belt from the power steering pump. Remove the mounting bolts for the pump. Without disconnecting the hoses, move the pump out of the way.
7. Unplug the alternator wiring and connectors; remove the engine wiring harness from the valve cover.
8. Loosen the adjusting and mounting bolts for the alternator and/or compressor. Remove the drive belt(s).
9. Remove the valve cover.
10. Remove the side engine mount support bracket, if equipped.
11. Remove the upper timing belt cover.
12. Support the engine with a floor jack on the oil pan (use a cushion between the jack and pan). Tension the jack so that it is just supporting the engine but not lifting it.
13. Remove the side engine mount.
14. Remove the dipstick and dipstick tube.
15. Remove the crankshaft pulley bolt and remove the crankshaft pulley.

This bolt is one of the tightest on the entire car. The pulley must be held in place while the bolt is loosened. One trick is to wrap an old drive belt around the pulley to hold it steady-don't try this with a belt that is to go back on the car; it will be stretched or damaged.

1. If necessary for additional clearance to remove the lower timing belt cover, remove the two rear bolts from the center beam. Slowly lower the jack and the engine until the clearance is gained.
2. Remove the rubber seal from around the belt tension adjusting nut (do not loosen the nut). Remove the lower timing belt cover.
3. On all models except Prelude with VTEC, lock the timing belt adjuster arm in place using one of the lower cover (6 x 1mm) mounting bolts.

Fig. 10: On all engines except VTEC, the belt adjuster arm must be locked in place using one of the lower cover mounting bolts
There are two belts in this system; the one running to the camshaft pulley is the timing belt. The other, shorter one drives the balance shaft and is referred to as the balancer belt or timing balancer belt. Use a piece of chalk or a marker to place an identifying arrow on the belts. The arrow can identify the direction of rotation or the outer edge of the belts. The belts must be reinstalled so it moves in the same direction. Protect the belts from oil, coolant, etc. It's an even better idea to replace the belts at this point.

1. Loosen the timing belt adjustment nut. Push on the tensioner to relieve tension from the balancer belt, then tighten the nut. Remove the balancer belt.
2. On all models except Prelude with VTEC, loosen the lockbolt installed earlier and the adjusting nut. Push on the tensioner to release the timing belt, then tighten the nut. Carefully remove the timing belt. On Prelude VTEC models, remove the timing belt from the pulleys, then remove the bolts securing the auto-tensioner. Remove the auto-tensioner from the engine.

   1. Hold the auto-tensioner with the maintenance bolt facing up. Loosen and remove the bolt. NOTE: Handle the tensioner carefully so the oil inside does not spill or leak. Replenish with clean engine oil if any does leak. Total capacity is 1⁄4 fl. oz. (8 ml).
      
   2. Clamp the mounting flange of the tensioner in a vise using a cloth or blocks of wood to protect it. Insert a flat blade screwdriver into the maintenance hole. Place the stopper (tool number 14540-P13-003) or an equivalent clamp on the tensioner, then turn the screwdriver clockwise to compress the bottom. Be careful not to damage the threads or the gasket contact surface.
   3. Install the maintenance bolt on the tensioner with a new gasket. Tighten to 6 ft. lbs. (8 Nm).
   4. Make sure no oil is leaking from around the maintenance bolt, then install the tensioner on the engine. Make sure the stopper stays in place and tighten the bolts to 16 ft. lbs. (22 Nm).
   5. Remove the stopper. Fig. 11: On VTEC engines, the tensioner must be compressed before installing it on the engine
      Fig. 12: Remove the stopper after installing the tensioner on the engine
      
   
   
9. Make sure all timing marks are positioned correctly (as described earlier).
10. Align the rear timing balancer pulley (to the right of the crank pulley) using a 6x100mm bolt or rod. Mark the bolt or rod at a point 2.913 in. (74mm) from the end. Remove the bolt from the maintenance hole on the side of the block; insert the rod into the hole. Align the 74mm mark with the face of the hole. This pin will hold the shaft in place during installation.
11. Loosen the tensioner adjusting nut and verify that the timing balancer belt adjuster moves freely. Fig. 13: The balancer shaft must be held in position during timing belt installation
    
    
12. Fit the balancer belt over the pulleys. Remove the bolt or rod from the maintenance hole.
13. Temporarily install the crank pulley. Rotate the engine one turn counterclockwise, then tighten the tensioner adjusting nut to 33 ft. lbs. (45 Nm). Double check the positions of the timing marks and make sure they still line up. If not remove the belts and repeat the procedures. NOTE: Both belt adjusters are spring-loaded to properly tension the belts. Do not apply any additional pressure to the pulleys or tensioners while performing the adjustment.
    
14. Remove the crank pulley. Remove the lockbolt installed earlier on the timing belt adjuster arm. Install the maintenance bolt with a new washer. Tighten it to 22 ft. lbs. (30 Nm).
15. Install the lower cover, making certain the rubber seals are in place and correctly located. Tighten the retaining bolts to 9 ft. lbs. (12 Nm).
16. If applicable, raise the lower beam and engine into place. Install the rear bolts for the lower beam. Tighten them to 28 ft. lbs. (39 Nm) on 1990–91 Accords, 37 ft. lbs. (50 Nm) on 1992–95 Accords and 43 ft. lbs. (60 Nm) on 1992–95 Preludes.
17. Install the key on the crankshaft and install the crankshaft pulley. Apply oil to the bolt threads and tighten it to the following:
    • 1990 Accord: 166 ft. lbs. (230 Nm)
    • 1991–93 Accord: 159 ft. lbs. (220 Nm)
    • 1992–93 Prelude: 159 ft. lbs. (220 Nm)
    • 1994–95 Accord and Prelude: 181 ft. lbs. (245 Nm)
18. Install the dipstick tube and dipstick.
19. Install the side engine mount (refer to engine removal and installation for procedures). Remove the jack from under the engine.
20. Install the upper belt cover.
21. Install the side engine mount support bracket if it was removed.
22. Install the valve cover.
23. Install the compressor and/or alternator drive belt; adjust the tension.
24. Route the wiring harness over the valve cover and connect the wiring to the alternator.
25. Install the power steering pump and install the belt.
26. Reinstall the cruise control actuator. Connect the vacuum hose and the electrical connector.
27. Double check all installation items, paying particular attention to loose hoses or hanging wires, untightened nuts, poor routing of hoses and wires (too tight or rubbing) and tools left in the engine area.
28. Refill the engine coolant.
29. Install the splash shield under the engine.
30. Connect the negative battery cable.
31. Start the engine, allowing it to idle. Check for any signs of leakage or any sound of the belts rubbing or binding.
