Question about Ford E-150

1 Answer

Ford 302 in E-150 is turning all drive belts into dental floss


There are 4 belts: alternator, air pump, power steering, A/C -- all four are being chewed down to nothing in about 500 miles driving. All but the air pump belt are either driven by the crank pulley or the water pump pulley.

I have:

- checked pulley alignment even w/ engine running -- no alignment problems found

- checked for excessive vibration -- none observed

- removed crank pulley -- no defects found

- removed harmonic balancer -- no defects found

- checked and rechecked belt tension

I have noticed recently some noise (like the fan hitting the shroud during accelerating turns) which I think could be a motor mount problem.

Also, there is a recent vibration when the engine is pulling -- I think this is a U-Joint going bad.

These two symptoms above are recent -- the v-belt problem predates them, but these two things could be a factor -- I don't know how, but anything is possible I guess.

One other point of interest: I had a garage put in a new engine about 4000 miles ago. They installed the wrong flywheel (a 28 ounce versus 50 ounce). This caused excessive vibration and could have damaged crank bearings. It was driven about 1800 miles before I could convince them they had installed the wrong flywheel and they should replace it (it's a very long story). In any event, there doesn't seem to be any damage to the engine, but I wouldn't know without taking it apart.

The belts were fine for the first 2000 miles I drove it after the correct flywheel was installed -- then the shredding started.

So what could be causing the belts to wear down to nothing?


P.S.

My next move is to replace the crank pulley although I (and others) can't find anything wrong with the one that's on it now.

    I removed and reinstalled the damper and it's torqued to spec.



    I have not compared crank pulley diameters -- the engine is not same as original -- finding out what it's supposed to be may be difficult -- but maybe not

    Yes, I see where you are going -- it's a good point. But the belts didn't shred for a couple of years after the engine was replaced. I would think if it's a "fast pulley" problem, the belts would have been shredding all along.

    A trip to a wrecking yard with a measuring tape might shed some light. Check more than one like yours. Obviously you see where I'm going with this thought right?
    Larger diameter pulley would have those belts rotating faster. Check V groove width too. Improper belts came to mind also. Just a thought.

Here are a few choices. If equipped with A/C the air could ice up the compressor and stop the a/c clutch, shredding a belt. Width of belt pulley, if narrow pulley has fat belts and fat pulley has narrow belts, then possible to shred. Has anyone cranked down the damper on the crankshaft? If the bolt comes loose or the woodruff key is worn you could get a wobble from the crank.

How to replace the power steering belt on a 4g13



ADJUSTMENT

Excessive belt tension will cause damage to the alternator and water pump pulley bearings, while, on the other hand, loose belt tension will produce slip and premature wear on the belt. Therefore, be sure to adjust the belt tension to the proper level.
To adjust the tension on a drive belt, loosen the adjusting bolt or fixing bolt locknut on the alternator, alternator bracket or tension pulley. Then move the alternator or turn the adjusting bolt to adjust belt tension. Once the desired value is reached, secure the bolt or locknut and recheck tension.

INSPECTION

All Models
Belt tension is very important, as a belt that is too tight will put too much stress on the bearings of the components it drives, causing them to wear out prematurely. A belt that is too loose will slip, causing (1) the belt to wear out quickly due to friction heat, and (2) inefficient alternator, air pump, cooling fan or air conditioner operation because much of the turning power supplied by the main drive pulley is lost.
The belts should be inspected and/or adjusted at 2,000 miles (3,221 km) and then every 4,000 miles (6,441 km). First, make sure that the belt is properly positioned in the pulley. Check the pulleys for damage. Inspect the belts for cracks and signs of fraying. These usually develop on the inner surface and extend into the backing or outer surface of the belt. Check also for glazing, a completely smooth appearance which indicates slippage. A belt that is in good shape will have a slightly grainy appearance like cloth. Replace belts that show cracks or glazing.
Check belt tension. Apply pressure with your thumb at the mid-point between two pulleys, and the belt should stretch or deflect about 1 / 4 - 1 / 2 in. (6-13mm). If the belt is too tight or too loose, adjust/replace as necessary.


ADJUSTING

Except RX-7
See Figures 1, 2 and 3
To adjust belts, first locate the mounting bolt on the air pump or alternator (each has its own belt and adjusts to permit that belt to be tensioned correctly). This bolt attaches the unit to the engine and has a nut on the end. Put a wrench on either end and loosen the bolt until there is practically no tension on it. Then, loosen the adjusting bolt, which is located on the opposite side of the unit and which passes through a slot. Pull the alternator or air pump away from the engine and tighten the adjusting bolt just enough to hold the unit while you check tension. Repeat the adjustment procedure until the belt deflects the proper amount, then fully tighten the adjusting and mounting bolts. Avoid too much belt tension or overtightening of bolts. A new belt should be tensioned just slightly more (about 0.4 in. or 10mm deflection) and checked after several hundred miles of operation to make sure that tension is still adequate. (Tension is lost very rapidly until a new belt is broken in.)

Fig. Fig. 3: On some GLC engines equipped with power steering, the pump pulley uses a slotted adjusting bar, adjusting bolt and locknut to adjust belt tension
Late model GLCs, 323s, 626s, MX-6s and 929s may use an adjusting bolt on either the idler pulley (a pulley which is not directly associated with any of the accessories) or on the power steering pump itself. This bolt makes adjustment much easier because you don't have to hold the accessory under a great deal of tension while tightening the mounting bolts.
On models where the idler pulley has a locknut at its center, simply loosen the locknut, then turn the adjusting bolt clockwise to increase belt tension or counterclockwise to decrease it or remove the belt. Do not forget to retighten the locknut when tension is correct, or vibration may cause it to fall off. Recheck the tension with the locknut tightened and readjust if necessary.
To adjust the power steering pump pulley on the GLC, loosen the slotted adjusting bar bolt, the mounting bolt across from it, and the locknut at the bottom of the adjusting bolt. Turn the adjusting bolt counterclockwise to remove the belt or reduce tension, and clockwise to increase it. When tension is correct, tighten the adjusting bolt locknut, adjusting bar bolt, and pump mounting bolt.
On 626, MX-6 and 929 models with a 4-ridge or 5-ridge ribbed type V-belt driving both the air conditioner and power steering pump, belt tension is much greater. With a used belt, deflection should only be about 1 / 4 in. (6.35mm).
RX-7
See Figures 4, 5 and 6
The RX-7 may be equipped with as many as three or four separate drive belts. The belts are arranged at the front of the engine and drive the cooling fan/water pump, alternator, power steering pump, emission control air pump and air conditioner compressor (if so equipped).

REMOVAL & INSTALLATION

All Models

  1. Loosen the accessory being driven and move it on its pivot point to free the belt.
  2. Remove the belt. If an idler pulley is used, it is often only necessary to loosen the idler pulley to provide enough slack to remove the belt.

To install:
  1. After the new belt is in place and properly tensioned, start the engine and allow it to run for about five minutes to seat the new belt.
  2. Stop the engine and recheck the belt tension. Adjust as necessary.

On engines with many driven accessories, other belts may have to be removed to access the one being replaced.

Can I drive a 2003 saturn L200 without serpentine belt?


As crazy as it sounds, I don't see why not. Based on my limited knowledge of a 2002 L200, the power steering is run off the back of the camshaft and the water pump is driven by the timing belt. The only things the serpentine belt runs are the A/C and alternator. Obviously you won't make it very far running without an alternator, but at worst you kill your battery. Serpentine belt on a 2.2l 4 cylinder 2002 L200 has nothing to do with the water pump or power steering pump.

ADJUSTMENT 1.8L Engines ALTERNATOR AND WATER PUMP BELT
  1. Loosen the alternator adjusting bolt.
  2. Raise and safely support the vehicle.
  3. Loosen the alternator mounting bolt. NOTE: Do not pry against the stator frame. Position the prybar against a stronger point, such as the area around a case bolt. Fig. 1: A belt tension gauge should be placed on the longest span of the belt to check tension — 1.8L engine 90981g05.gif

  4. Position a suitable belt tension gauge on the longest accessible span of belt and tighten the belt.
  5. Adjust the tension to 86–103 lbs. (383–461 N) for a new belt or 68–86 lbs. (304–383 kg) for a used belt.
  6. If a belt tension gauge is not available, adjust the tension to 0.31–0.35 in. (8–9mm) deflection for a new belt or 0.35–0.39 in. (9–10mm) deflection for a used belt.
  7. Tighten the alternator adjusting bolt to 14–19 ft. lbs. (19–25 Nm).
  8. Tighten the alternator mounting bolt to 27–38 ft. lbs. (37–52 Nm).
  9. Lower the vehicle. Fig. 2: Alternator and water pump pulley belt routing — 1.8L engine 90981g06.gif
POWER STEERING PUMP BELT
  1. Raise and safely support the vehicle.
  2. Loosen the power steering pump mounting bolt and nuts.
  3. Adjust the power steering pump and, if equipped, the air conditioning compressor belt tension by turning the pump adjusting bolt. Fig. 3: Power steering pump belt routing and locations of the mounting bolts, nuts and adjusting nut — models without A/C 90981g07.gif

  4. Tighten the power steering pump mounting nut near the pump adjusting bolt.
  5. Position a suitable belt tension gauge on the longest accessible span of belt and tighten the belt.
  6. Adjust the tension to 110–132 lbs. (491–589 N) for a new belt or 95–110 lbs. (422–491 N) for a used belt.
  7. Check for proper belt deflection. For a new belt (one with less than 10 minutes of run time), the deflection should be 0.31–0.35 in. (8–9mm). For a used belt (one with more than 10 minutes of run time), the deflection should be 0.35–0.39 in. (9–10mm).
  8. Tighten the power steering pump mounting nut, located near the adjusting bolt, to 27–38 ft. lbs. (37–52 Nm).
  9. Tighten the pump mounting bolt behind the pulley to 27–40 ft. lbs. (36–54 Nm), and the remaining pump mounting nut to 23–34 ft. lbs. (31–46 Nm).
  10. Lower the vehicle. Fig. 4: Power steering pump belt routing and locations of the mounting bolts, nuts and adjusting nut — models with A/C 90981g08.gif
1.9L Engines The accessory drive belt for 1.9L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner. NOTE: Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension. Fig. 5: Drive belt routing — 1.9L engines 86751052.gif

Power steering went out while driving and battery


If the belt gets wet and flies off, or starts to slip, the power steering and alternator will stop spinning causing this condition.

Check belts to see if they are still on the truck and spinning the pulleys of the alternator and power steering pump.

How to remove alternator



Park vehicle on level ground.
2. Remove battery from vehicle.
3. Remove air cleaner outlet hose, engine under cover ( right side ) and exhaust pipe # 2 .
4. Disconnect " B " terminal wire and coupler from the Alternator ( Generator ) .
5. Remove Alternator ( Generator ) belt.

6. Remove power steering pump. Do not disconnect hoses.
6. Remove Alternator ( Generator ) cover.
7. Remove Alternator ( Generator ) bracket mounting bolts.
8. Remove Alternator ( Generator ).

Power Steering pump has three bolts- 2 behind the pulley at 12 and 6 o'clock and one bolt on the back.

Once you get the power steering pump out of the way you can remove the last bolt on the alternator


Ok...I did not remove axle or disconnect hoses on power steering...I did unbolt power steering pump and moved off to side.

after that I disconnected sensor on throttle body and very carefully lifted alternator through the top where your air intake assembly would have been at, right next to A.C. refrigerant lines.It takes a minute , you HAVE TO BE CAREFUL NOT TO DAMAGE SENSOR!!

However it is a lot faster that taking off drive shaft and exhaust pipe!

If you go to AutoZone .com they have exploded diagrams of the parts you have to take off and they will show you bolt locations, the power steering pump bolt at 6 o'clock drove me crazy.

P.S. Get a ratcheting 12 mil wrench, it's a life and knuckle saver!!
