Balance shaft timing on 1989 Sonata 2.4

I have a 1989 Hyundai Sonata with the 2.4 engine. The bearing on the balance shaft belt tensioner collapsed. What marks do I align when reassembling and how much tension should I put on it?

Thanks

no, when taken out should have been marked to go back the same way. when u joints changed did they move freely or were they stiff to move if so that can cause a out of balance problem

Hi there. I can solve this dangerous problem you are having. You would loose acceleration at lights and intersections, the engine will shake and revs can go crazy. The issue is the MAF (mass air flow) sensor. It was recalled in 2001 as a safety problem as people died driving this model of sonata. If you connect your comp up to a diagnostic machine you will find its the MAF the problem is a problem that is hard to ctah on a diagnostic machine though as it comes and goes. You will need to replace the MAF ASAP as you can die from this fault and hyundai will not care due to the age of this car.

I have a 2004 Hyundai sonata 2.4L engine with automatic transmission. When a crankshaft sensor is replaced, it is neccessary to have the timing belt and its tensioner replaced also?


The 2.4 L engine has a timing belt & a balance belt. They should be replaced every 60,000 miles or every 5 years (whichever comes first). During belt replacement, the tensioner should be inspected for proper operation. If it's leaking grease or has collapsed, it must be replaced.

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.

2bd7a51.jpg
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.

            Hyundai Balance Shaft Bearing making noise?


            Possible. It's hard to give you an accurate cause, since I'm not able
            to hear the sound. Most of the time, when you hear a slight wrapping
            sound, it's a rod bearing,or crank bearing. When the rod bearing goes,
            you'll know it,since it will knock like an SOB.

            There are Two Balance Shafts on the 2.4. Did your mechanic also change the balance shaft belt when he changed the timing belt? If he didn't, you'll want to do that. Since you mentioned the old belt was missing teeth, those loose teeth flying around could have damaged the crank position sensor and sensor blade (tone wheel). Also, the front balance shaft (on the side of the engine nearest the radiator), has THREE different positions when the timing mark is lined up - here's the glitch - ONLY ONE of them is the correct one - this is probably where your vibration is.

            Which engine? 4 cylinder (2.4 lit) or V6 (2.7 lit)? Two different procedures as well as different belts. The 4 cylinder also has a balance belt. See next image:
            42e8a57.jpg
            Here's the 2.7 V6 belt:

            44efb27.jpg
            The replacement procedure is nearly the same at the start (removing, accy drive belts, pullys, support engine & remove front engine mount, remove T.B covers, disconnect Cam Position Sensor & Crank Position Sensor connectors, etc.). When you get to this point on the V6, you also have to remove the front engine mounting bracket from the front of the engine (4 14mm bolts, also a 12mm bolt which bolts the dipstick tube to the side of it) Put crank shaft at TDC (top dead center w/ALL timing marks aligned) remove hydraulic tensioner (2 12 mm bolts), then remove the belt. You'll need to recompress the hydraulic (auto) tensioner in a vise and insert a retaining pin through the pin-holes at the top (through the tensioner piston) to keep it compressed when you reinstall it. Otherwise, you won't be able to install it. Assembly is reverse order of dissassembly. Inspect your pullys while you're in there (check for pully bearing noise, leaking grease, smooth rotation, also the water pump pully, etc.) Replace components as needed. Careful not to damage Crankshaft Position Sensor wire harness.

            The 4 Cylinder is quite different. You not only change the timing belt, but also the countershaft (balance) belt, which is behind the crank position sensor blade. IMPORTANT: ALL TIMING MARKS ALIGNED BEFORE REMOVING ANYTHING) There are two (2) counter-shafts (balance shafts). one driven by the timing belt, the other by the crankshaft sprocket behind the timing belt sprocket at the front of the crankshaft.
