Idler spring came off when belt broke, not sure correct placement for spring and idler pulley

The spring is from the Idler / Tensioner pulley.

1.6 engine, timing belt. 4A not 4AF. F = twin cam.
V.I.N. code 6 not 5, the 5is twin cam 4AFE twin.
the car is a Corolla, and as such info is easy to find on toys,
so that the engine real name is.

so you dont want all the facts? marks and how to set tension correctly? really? at #12 and 18?
getting all this right, makes it GO 60k more miles, (a fact)

the words.

1. Remove the timing belt covers using procedures described earlier in this section.
2. If not done as part of the cover removal, rotate the crankshaft clockwise to the TDC/compression position for No. 1 cylinder.
3. Loosen the timing belt idler pulley to relieve the tension on the belt, move the pulley away from the belt and temporarily tighten the bolt to hold it in the loose position.
4. Make matchmarks on the belt and both pulleys showing the exact placement of the belt. Mark an arrow on the belt showing its direction of rotation.
5. Carefully slip the timing belt off the pulleys.
6. dont move cam, with belt off it warns.
7. Remove the idler pulley bolt, pulley and return spring.
8. Use an adjustable wrench mounted on the flats of the camshaft to hold the cam from moving. Loosen the center bolt in the camshaft timing pulley and remove the pulley.
9. Check the timing belt carefully for any signs of cracking or deterioration. Pay particular attention to the area where each tooth or cog attaches to the backing of the belt. If the belt shows signs of damage, check the contact faces of the pulleys for possible burrs or scratches.
10. Check the idler pulley by holding it in your hand and spinning it. It should rotate freely and quietly. Any sign of grinding or abnormal noise indicates replacement of the pulley.
11. Check the free length of the tension spring. Correct length is 38.5mm measured at the inside faces of the hooks. A spring which has stretched during use will not apply the correct tension to the pulley; replace the spring.
12. If you can test the tension of the spring, look for 8.4 lbs. of tension at 50mm of length. If in doubt, replace the spring.
13. Reinstall the camshaft timing belt pulley, making sure the pulley fits properly on the shaft and that the timing marks align correctly. Tighten the center bolt to 43 ft. lbs.
14. Before reinstalling the belt, double check that the crank and camshafts are exactly in their correct positions. The alignment mark on the end of the camshaft bearing cap should show through the small hole in the camshaft pulley and the small mark on the crankshaft timing belt pulley should align with the mark on the oil pump.
15. Reinstall the timing belt idler pulley and the tension spring. Pry the pulley to the left as far as it will go and temporarily tighten the retaining bolt. This will hold the pulley in its loosest position.
16. Install the timing belt, observing the matchmarks made earlier. Make sure the belt is fully and squarely seated on the upper and lower pulleys.
17. Loosen the retaining bolt for the timing belt idler pulley and allow it to tension the belt.
18. Temporarily install the crankshaft pulley bolt and turn the crank clockwise 2 full revolutions from TDC to TDC. Insure that each timing mark realigns exactly.
19. Tighten the timing belt idler pulley retaining bolt to 27 ft. lbs.
20. Measure the timing belt deflection (Tool 23600 B or similar), looking for 5-6mm of deflection at 4.4 pounds of pressure. If the deflection is not correct, readjust the idler pulley by repeating steps 15 through 18.
21. Remove the bolt from the end of the crankshaft.
22. Install the timing belt guide onto the crankshaft and install the lower timing belt cover.
23. Continue reassembly of the timing belt covers as outlined previously in this section.

Go to your local cub dealer with the modle number of the deck. They have diagrams that will show how to connect the spring correctly. If the spring came off it may have lost tension or part of the hooks on the end of the spring broke off. I would get a new spring. I have also seen the the idler pully get sloppy and not keep the idler pully properly lined up with the other pulleys.The belt will then ride up off the pulley and the spring will come off.

1st, Unplug the Dryer from the Power Supply.
You will need the Exact recommended Replacement "Idler Pulley".
With the Belt Ribs Facing Toward the Dryer Drum, position the belt on the tell tale Ring Mark on the Drum letting the Belt Hang Down below the Drum.
Place The New Idler Pulley into the Slots on the Inside Dryer Bottom located near the Motor Mounted Pulley.
(Face The Idler Pulley Toward The Motor Mounted Pulley)
(Hold the Idler Pulley in place in the slots)
Take the "Hanging Belt" & run the Whole Loop "UNDER" the Idler Pulley & then
Attach the "Belt Loop" "AROUND" The Motor Mounted Pulley.
That should do it.
Put the rest of the Dryer Back Together...Done!
Good Luck,
Vinnie

Removal & Installation

1. Rotate the drive belt tensioner clockwise and remove the drive belt.
   WARNING Never suddenly let go of the tensioned idler pulley. The force of the spring pressure suddenly released may damage the idler pulley mechanism. Always release the spring pressure gradually.
   
   
   

   Fig. Rotate the belt tensioner to relieve tension on the belt-4.6L engine shown, others similar
   

To install:

1. Route the belt over the pulleys making sure all the grooves in the pulleys and the belt line up correctly. Refer to the accessory belt routing section of this manual.
2. Rotate belt tensioner clockwise and slip drive belt over idler pulley on tensioner.

1. Rotate the drive belt tensioner clockwise and remove the drive belt.
   WARNING Never suddenly let go of the tensioned idler pulley. The force of the spring pressure suddenly released may damage the idler pulley mechanism. Always release the spring pressure gradually.

If for any reason, the tensioner is crooked, replace it!!! Also, install the belt with the writing facing you like you are trying to read a book. This WILL (a trick I learned at Mercedes) prevent even a new belt from squeeling!!

How to replace the drive belt on a Toro LX466 Lawn Tractor

1. Jack up the front of the mower-place a couple of blocks under the front wheels (retaining wall blocks from your flower bed work great). Block the back wheels so the mower won't roll off the front blocks.

1. Remove the battery and battery compartment from under the seat. You can now see the cooling fan blade under the seat. The belt runs from the pulley directly under the fan to the front of the tractor.
   

2. Lower the mower deck to its lowest position. Remove the deck hanger rod from the slots in the front of the mower deck.
   

3. Remove the metal rod guard below the engine pulley. It's held in place on one side with a bolt, and the other side with a cotter pin.
   

4. Take a large pair of channel lock pliers (about 18 in long work great) and clamp them down directly on the engine pulley, but not so tightly you distort the pulley.
   

5. Remove the bolt from the pulley. It's a right-handed bolt, so turn it counter-clockwise to remove.
   

6. Slide the pulley down the shaft until you can work the belt off. If the belt is too tight, then remove the spring from the idler pulley under the tractor. It's hooked on a bolt near the side of the tractor. You can remove it by grabbing the end of the spring with a pair of needle-nose vise-grips and slipping the end off the bolt. Then remove the old belt from the tractor.
   

7. Take a new belt (preferably Kevlar) and start at the back of the tractor (with the pulley under the cooling fan) and thread it through to the front of the tractor. The flat side of the belt rests against the idler pulley with the flat sides.
   

8. Work the belt over the engine pulley and slide it back on the shaft. Tighten the bolt on the engine pulley hand tight. Then check the belt to make sure it hasn't slipped out of the groove on the cooling fan pulley.
   

9. Clamp the engine pulley with the channel lock pliers and tighten the bolt.
   

10. Make sure the belt is routed correctly on the idler pulleys. If you had to remove the spring on the idler pulley, replace it. You can do this by grabbing it with the needle-nose vise-grips and placing it on the bolt-make sure it's above the washer. Then remove the vise-grips and gently pry it over with a small screwdriver until it slips into place.
    

11. Replace the metal guard below the engine pulley. Hook the mower deck back onto the deck hanger. Replace the battery compartment and battery. Unblock the mower.
    

Make sure the routing of the belt is correct, pay attention to tension pulley. Make sure belt is also not stretched you might need new belt.

Remove the housing with the machine off

The idler pulley is designed to push up against the outside of the belt between the drive and motor pulleys when disegaged the belt should look like a loop like a race track

engage the blade clutch and watch to see if it presses up against the drive pully and the motor pulley

their should be a spring attached to the idler arm and i believe the new belt is dragging a little

you should be able to move the belt with your hands ( it should slip freely) rod is engaged or it pulls the idler away

Either a spring causes tension when the rod is engaged or it pulls the idler away

Keep working with it until it is free you may have an adjustment on the spring tension or the linkage rod has an adjustment

I am sure you can do this without an diagram good luck
