My balance shaft belt broke while I was driving. It stripped some of the teeth off the timing belt and Im pretty sure it jumped time. I need a diagram to show the timing marks and how to get it back in...


see diagrams from autozone.com. Cam sprocket has an "UP" label, but also 2 scribes on the sides to align to upper head surface. The critical part of the job is keeping tension on the side of the belt that is opposite from the tensioner as the tensioner is released onto the belt. The timing marks must be aligned when the job is done.

4256a1c.gif To install:

  1. Install the camshaft timing sprocket so that the UP mark is up and the TDC marks are parallel to the cylinder head gasket surface. Install the key and tighten the bolt to 27 ft. lbs. (37 Nm).
  2. Install the crankshaft sprocket so that the TDC mark aligns with the pointer on the oil pump. Install the spacers with their concave surfaces facing in. Install the key. If equipped, install the TDC sensor assembly back into position before installing the timing belt.
  3. Install and tension the timing belt. Use a 6 x 1.0 mm x 25 mm bolt threaded through the cam belt tensioner plate to temporarily hold the tensioner.
  4. Temporarily install the crankshaft pulley and rotate the crankshaft counterclockwise 5-6 turns to be sure the belt is properly seated.
  5. Set the No. 1 piston at TDC for its compression stroke.



WARNING If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.

  1. Rotate the crankshaft counterclockwise so that the camshaft pulley moves only 3 teeth beyond its TDC mark.
  2. Loosen, then retighten the temporary cam belt tensioner bolt.
  3. If the rear balance shaft sprocket/gear case assembly was removed, perform the following:
    1. If the rear balance shaft was moved, rotate the balance shaft until the 6 x 1.0mm x 100 mm bolt can be installed into the maintenance hole to the scribed line.
    2. Align the notch of the balance shaft sprocket edge with the pointer on the gear case. Install the rear balance shaft sprocket/gear case assembly using a new O-ring coated with fresh engine oil. The balance shaft sprocket should be installed in the TDC position. The pointer on the gear should align with the pointer on the oil pump housing plate.
    3. Tighten the mounting bolts to 18 ft. lbs. (25 Nm).

  4. If the front balance shaft sprocket was removed, perform the following:
    1. Install a suitable and sturdy screw driver or drift through the maintenance hole in the shaft behind the sprocket to hold the front balance shaft.
    2. Install the front balance shaft sprocket and mounting nut. Torque the nut to 22 ft. lbs. (29 Nm).

  5. Make sure the balance shafts and crankshaft are in the TDC position.
  6. Remove the crankshaft pulley, and if removed, install the balance shaft belt drive sprocket.
  7. Install the balance shaft belt, making sure the balance shafts and sprockets are still in the TDC position.
  8. If removed, install the balance shaft belt tensioner and tension the balance shaft belt.
  9. Loosen, then retighten the tensioner adjusting nut to 33 ft. lbs. (45 Nm).
  10. Remove the 6 x 1.0mm x 100mm rear balance shaft holding bolt.
  11. Temporarily install the crankshaft pulley and rotate the crankshaft 2 revolutions counterclockwise, stopping at TDC.



WARNING If any resistance is felt, stop immediately and determine the cause.

  1. Recheck that all of the TDC marks align for both the camshaft and balance shafts.
  2. Loosen, then retighten the tensioner adjusting nut to 33 ft. lbs. (45 Nm).
  3. Remove the 6 x 1.0 mm x 25 mm bolt used to secure the camshaft timing belt tensioner.
  4. Remove the crankshaft pulley and install the lower cover.
  5. Install the crankshaft pulley, lubricate the bolt threads and both sides of the crankshaft pulley bolt with fresh engine oil and tighten the crankshaft pulley bolt to 181 ft. lbs. (245 Nm). Do Not use an impact wrench.
See Figures 19 and 20

            1. Install the upper timing cover and the valve cover. Be sure the seals are properly seated.
            2. Install the side engine mount. Tighten the through-bolt to 47 ft. lbs. (64 Nm). Tighten the mount nut and bolt to 40 ft. lbs. (55 Nm) each.
            3. Remove the floor jack.
            4. Install and tension the alternator belt.
            5. Install the power steering pump and tension its belt.
            6. Install the splash shields.
            7. Reconnect the positive and negative battery cables. Enter the radio security code.
            8. Check engine operation.

            How do u change the timing belt on a 1990 4 cylinder honda accord?


            Disconnect the wire harness at the distributor.Remove the spark plug closest to the drivers side front tire. Place the palm of your hand over the valve covers empty spark plug hole and have a helper crank the motor over until air pressure pushes past your the palm of your hand. Next, look at the cam shaft wheel and note the direction that the arrow is pointing, the arrow should be pointing straight up IN RELATION TO THE ENGINE not the earth. If it is not, you will need to manually rotate the engine till the cam wheel is infact pointing straight up. Next, Jack up the front of the car and support it with jack stand and remove the front drivers side tire.Next, support the weight of the engine with a floor jack remove the motor mount closest to the drivers side tire To remove it you will need a deep 17mm socket on a heavy duty breaker bar. Next, loosen and remove the power steering belt and alternator belts. To loosen and remove the belts you will need a 10mm wrench and a 12mm wrench. And also a 14mm or 15mm wrench. Next, use a 19mm socket AND an air powered IMPACT wrench to remove the bolt holding on the crank shaft pulley. Next, remove the crankshaft pulley. Next, use a 10mm wrench and/or 10mm socket and remove the bolts holding the plastic engine side cover. Next, loosen the 14mm or 15mm bolt which secures the 2 belt tension wheels. Next, LOOSEN the 10mm bolt that is on the balance shaft tensioner. The balance shaft is the cogged wheel with a small timing mark dot on the side of the wheel. Next, loosen the 10mm bolt on the timing belt tensioner. It's obvious what wheel is the timing belt tensioner. Next, remove the 12mm bolt on the back side of the block (near the balance shaft) a little bit of oil will drip out, this 12mm bolt will allow a long bolt to be inserted into a recessed channel of the balance shaft. This recessed channel is needed to lock the balance shaft in place. A bolt from the air conditioner works great for locking the balance shaft in place. You're basically just pushing the bolt in a hole to keep the balance shaft from spinning.890a27a.jpg Next, remove both the balance shaft belt and timing belt. Then reverse the procedure to complete the new belt installation. EXTREMELY IMPORTANT!!!!!!!!! PLEASE NOTE, the oil pump wheel furthest to the left (closest to the radiator), has a timing mark on the flat face side of the wheel, that timing mark has to be pointing directly to the 9:o'clock position in relation to the engine. The cam wheel has an arrow on the side of one of the "spokes" ...make sure it is pointing straight up in relation to the engine...straight away from the crank shaft. Put the crank wheel on with the arrow pointing straight up to the center of the cam wheel.

            Balance shaft alinement marks on honda 2.3 litre engine


            set it to top dead center. there's an access hole to put a 4" or 100mm pin to keep the balance shaft from moving when replacing a timing belt. The other marks are at the cam and crankshaft pulleys.

            Or remove #1 cylinder spark plug, put a wooden rod against the piston, when it is at the top of it's travel and goes neither up or down, it is at top dead center. The balance shaft locking pin can then be inserted.

            I removed my timing belt from my 1992 honda accord


            The balance shafts have marks on their sprockets that line up with indents on the block. For the one with the pin, just use a drill bit shaft that seems to fit the best and look for the marks. You only have two choices as you turn the balance shaft and expose the alignment hole. One of those spots will have fairly obvious marks that line up at the sprocket. The other one has a mark toward the front of the block. I'll see if I can dig up a photo and post it. The other tricky part is tensioning the belts, it's done in two steps while half the tensioner is clamped in place by a spare timing cover bolt. If you need help with this, let me know.
            Please, please don't forget to remove the alignment pin or the bolt you used to clamp the tensioner!
