1994 Ford Explorer idler pulley assembly

Hi - the bushing went out on the idler pulley. The pulley stayed inside the engine compartment, but the bolt, washers, whatever stayed on the road, and when I went back, I couldn't find them. I've been looking online and I can't find what size or type of bolt I need to put the pulley back on...when you buy the pulley, the bolts don't come with it. Can you help?

How to replace a idler pulley on a 1997 international 4700 series


Hi Melissa:
Nice truck!
I'm assuming that the bearings in the idler pulley are shot which is why you're replacin the pulley. Pulley's are typically attached by a bolt through their centre. Replacing the idler consists of getting the bolt out and exchanging new for old. Here's the route I would recommend:
SAFETY FIRST - Disconnect negative battery terminal.
- Make a diagram of belt routing.
- Slacken idler and remove belt
- Remove Idler retaing bolt (Watch for washers or spacers)
- Install new Idler with washers or spacers in same position.
- Tighten retaining bolt.
- Use diagram to re-install belt;
- Re-connect negative battery terminal.
- Check for stray tools or loose objects.
Test run.

How to remove the idler pulley on a jeep grand cherokeen1994


which engine? we can not guess engines.
unless, stated, or show with a photo. (add photo)
open hood see EPA sticker and engine is clearly stated there. USA.

read the FSM
read alldata. com
ZJ
4.0L:?
do tell and we CAN answer.

idler on 4.0, just it, is IT bad, or just a belt swap, do tell.
serpentine belt.
the book says, engine with no power steering (you) do have
spring loaded, idler, but the other engines and with power streering
NOT.
so is this a P/S free car" I must assume so this is the FSM quote for taht
special case: (ive never seen a P./s free GC) but here goes.
If the engine is equipped with an idler pulley, loosen the idler pulley adjusting bolt, insert a prybar between the pulley and the engine (or in the idler pulley adjusting slot), and adjust the tension accordingly. If the engine is not equipped with an idler pulley, the alternator must be moved to accomplish this adjustment, as outlined under Alternator Belt.

why not post a photo of the part that cant be removed.????

but if V8?? (it should not be, as that was introduced in 1994)(
it has a turn bolt CW to release tension, on V8 idler.
my book dont show how to remove said pulley
but I think yours is broken.

Where do I find the timing marks on pulleys?


in the factory service manual FSM.

or

login to

alldata.com

and read all the steps



3VZ-FE (and 2vz)
this is your engine. and has many steps

key is timing and proper belt tension and is free running engine.



quote

Prior to timing belt removal, make sure all the match-marks are there-2VZ-FE and 3VZ-FE engines

less photos:

the crank mark is CR -line

the cam pulleys, 3v pulley to R-cam mark

and 3v pulley to L-cam mark. (photos are best).





  1. Remove the timing belt.


If the timing belt is to be reused, draw a directional arrow on the timing belt in the direction of engine rotation (clockwise) and place matchmarks on the timing belt and crankshaft gear to match the drilled mark on the pulley.



  1. With a 10mm hex wrench, remove the setbolt, plate washer and the No. 1 idler pulley.


  2. Remove the crankshaft timing pulley, if it can NOT be removed by hand, use two flat bladed tools. Position shop rags on the components to prevent damage.


TO INSTALL:



  1. Turn the crankshaft until the key groove in the crankshaft timing pulley is facing upward. Slide the timing pulley on so that the flange side faces inward.


  2. Apply bolt adhesive to the first few threads of the No. 1 idler pulley setbolt, install the plate washer and pulley and then tighten the bolt to 25 ft. lbs. (34 Nm).


  3. Install the timing belt on the crankshaft timing, No. 1 idler and water pump pulleys.


If the old timing belt is being reinstalled, make sure the directional arrow is facing in the original direction and that the belt and crankshaft gear matchmarks are properly aligned.



  1. Install the lower (No. 1) timing cover and tighten the bolts.


  2. Align the crankshaft pulley set key with the key groove on the pulley and slide the pulley on. Tighten the bolt to 181 ft. lbs. (245 Nm).


  3. Install the No. 2 idler pulley and tighten the bolt to 29 ft. lbs. (39 Nm). Check that the pulley moves smoothly.


  4. Slide the left pulley, facing the flange side outward. Align the knock pin hole of the camshaft with the knock pin of the timing pulley, then install the knock pin. Tighten the left camshaft timing pulley bolt to 80 ft. lbs. (108 Nm).


  5. Set the No. 1 cylinder to TDC again. Turn the right camshaft until the knock pin hole is aligned with the timing mark on the No. 3 belt cover. Turn the left pulley until the marks on the pulley are aligned with the mark on the No. 3 timing cover.


  6. Check that the mark on the belt matches with the edge of the lower cover. If not, shift it on the crank pulley until it does. Turn the left pulley clockwise a bit and align the mark on the timing belt with the timing mark on the pulley. Slide the belt over the left pulley. Now move the pulley until the marks on it align with the one on the No. 3 cover. There should be tension on the belt between the crankshaft pulley and the left camshaft pulley.


  7. Align the installation mark on the timing belt with the mark on the right side camshaft pulley. Hang the belt over the pulley with the flange facing inward. Align the timing marks on the right pulley with the one on the No. 3 cover and slide the pulley onto the end of the camshaft. Move the pulley until the camshaft knock pin hole is aligned with the groove in the pulley and then install the knock pin. Tighten the bolt to 55 ft. lbs. (75 Nm).


  8. Position a plate washer between the timing belt tensioner and the a block and then press in the pushrod until the holes are aligned between it and the housing. Slide a 1.27mm (3VZ-FE 1.5mm) Allen wrench through the hole to keep the push rod set. Install the dust boot and then install the tensioner. Tighten the bolts to 20 ft. lbs. (26 Nm). Don\'t forget to pull out the Allen wrench!


  9. Turn the crankshaft clockwise two complete revolutions and check that all marks are still in alignment. If they aren\'t, remove the timing belt and start over again.


  10. Install the right engine mount bracket and tighten it to 30 ft. lbs. (39 Nm).


  11. Position a new gasket and then install the upper (No. 2) timing cover. refer to the illustration for bolt positioning.


  12. Install the spark plugs.


  13. On the 2VZ-FE, install the right engine mount insulator. Tighten the bolt to 47 ft. lbs. (64 Nm), the bracket nut to 38 ft. lbs. (52 Nm) and the body nut to 65 ft. lbs. (88 Nm). Install the No. 1 stay and tighten it to 38 ft. lbs. (52 Nm). Install the No. 2 stay and tighten the bolt to 48 ft. lbs. (66 Nm) and the nut to 38 ft. lbs. (52 Nm).


  14. On the 3VZ-FE, install the control rod and tighten the bolts to 47 ft. lbs. (64 Nm). Install the right stay and tighten it to 23 ft. lbs. (31 Nm).


  15. Install and adjust the drive belts.


  16. Install the fender apron seal and the wheel.


  17. On the 3VZ-FE, install the No. 2 stay and tighten the bolt to 55 ft. lbs. (75 Nm), the nut to 46 ft. lbs. (62 Nm). Install the No. 3 stay and tighten it to 54 ft. lbs. (73 Nm).


  18. Install the coolant overflow tank and the washer tank.


  19. Install the power steering reservoir tank and the cruise control actuator.


  20. Connect the battery cable, start the car and check for any leaks.

1996 Ford Mustang v6 coupe idler pulley and belt tensioner


I guess it depends on what failed.
The idler pulley is a simple pulley with a bearing held on by a large bolt.
If the bolt broke, or came loose, you may have problems keeping a new bolt in place.
If the bearing wore out and came apart, the bolt is probably still in the bracket. A failed bearing is common after 10 or 15 years, a loose bolt is somewhat rare.
The belt tensioner is another pulley mounted on a spring-loaded arm that keeps the belt tight. Same design but a different function.

  1. Temporarily install the No. 1 idler pulley with the retaining bolt. Hint: use a 1.65 inch (42mm) bolt in length. Do not tighten the bolt yet. Install the tension spring. Pry the pulley toward the left as far as it will go, then tighten the bolt.
  2. Turn the crankshaft until the key groove in the crankshaft timing pulley is facing upward. Install the timing belt on the crankshaft timing, oil pump, No. 2 idler and water pump pulleys.

If the old timing belt is being reinstalled, make sure the directional arrow is facing in the original direction and that the belt and crankshaft gear matchmarks are properly aligned.

  1. Install the lower (No. 1) timing belt cover and new gasket with the four bolts.
  2. Align the crankshaft pulley set key with the pulley key groove. Install the pulley. Tighten the pulley bolt to 80 ft. lbs. (108 Nm).
  3. On 2S-ELC engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
  4. Align the camshaft knock pin with the matchmarks on the oil seal retainer.
  5. On 2S-ELC/USA engines, align the knock pin with the pin hole on the timing pulley E mark side. On 2S-ELC/Canadian engines, align the knock pin with the pin hole on the timing pulley. On 3S-FE and 5S-FE engines, align the knock pin with the groove of the pulley, and slide the pulley onto the camshaft with the plate washer and set bolt.

On 2S-ELC engines, make sure that the Matchmark on the oil seal retainer and center hole of the small hole on the camshaft timing pulley are aligned.

  1. Using the removal tool to hold the pulley stationary, install and tighten the pulley set bolt to 40 ft. lbs. (54 Nm) on the 2S-ELC and the 3S-FE. On the 5S-FE, tighten the set bolt to 27 ft. lbs. (37 Nm).
  2. On 3S-FE and 5S-FE engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
  3. Install the timing belt and check the valve timing as follows:
    1. Align the matchmarks that you made previously, and install the timing belt onto the camshaft pulley.
    2. Loosen the No. 1 idler pulley set bolt 1 / 2 turn.
    3. Turn the crankshaft pulley two complete revolutions TDC to TDC. ALWAYS turn the crankshaft CLOCKWISE. Check that the pulleys are still in alignment with the timing marks.
    4. Tighten the No. 1 idler pulley set bolt to 31 ft. lbs. (42 Nm).
    5. Make sure there is belt tension between the crankshaft and camshaft timing pulleys.

  4. Install the upper (No. 2) timing cover with a new gasket(s). On the 5S-FE, align the two clamps for the engine wiring harness with the cover mounting bolts.
