Belt falling off/broken idley pulley mounting bracket/broken bolt

Hello, I havehad a Husqvarna GTH2654 for years and mostly had no issues. last year, the belt came off because the idler pulley bracket (welded onto the deck) broke. I had it welded back, no problem. This year, it broke off again. Had it welded again. After cutting the grass once, the Grade 5 bolt on the same idler broke in half and the belt came off again. Seems like the force being applied to that idler is too much. Any suggestions on where to look?

SOURCE: MTD Lawn Tractor: Constantly shredding deck belt...

I have the exact same model MTD tractor with same problem. It began when the bolt that extends through the idler arm assembly broke and subsequently damaged the pulley. Upon examination of the broken bolt, I found that the threaded end that extends below the deck is significantly smaller that the rest of the bolt. I got a larger bolt with the same size threads, bored out the hole through the deck and it made the whole idler assembly much stronger. the deck still has some vibration and some unusual belt harmonics, but it appears to be working. Compared to most other tractors of this size, this deck is very complicated.

Please could you give me a diagram of the valve timing of a double O.H.C.on a toyota Rav4 3SFE engine


no year(94-present) stated. and under kia dont help much.

its at alldtata.com, i read all the steps and not skip one, I WOULD.

wild guess, #1 a 2005 RAV4
2.0L 3sfe. inline 4 cylinder, not V6


here is the one i see on the FSM.

my gates belts all come with a manual. RTM?
if you buy the belt at a dealer they assume you have the FSM.
right?
FSM, install, steps
  1. Install the oil pump pulley. Tighten the nut to 18 ft. lbs. (24 Nm).
  2. Install the crankshaft timing pulley. Align the pulley set key with the key groove of the pulley. Slide on the pulley facing the flange side inward.
  3. Install the No. 2 idler pulley and tighten the mounting bolt to 31 ft. lbs. (42 Nm). Be sure that the pulley moves smoothly.
  4. Install the No. 1 idler pulley with the bolt and the tension spring. Pry the pulley toward the left as far as it will go and tighten the bolt. Make sure that the pulley moves smoothly.
  5. Temporarily install the timing belt. Using the crankshaft pulley bolt, turn the crankshaft and position the key groove of the crankshaft timing pulley upward. If reusing the timing belt, align the points marked during removal.
  6. Install the timing belt on the crankshaft timing pulley, oil pump pulley, No. 1 idler pulley, water pump pulley and the No. 2 idler pulley.
  7. Install the timing belt guide.
  8. Install the lower (No. 1) timing belt cover and new gasket with the 4 bolts.
  9. Align the crankshaft pulley set key with the pulley key groove. Temporarily install the crankshaft pulley and bolt.
  10. Align the camshaft knock pin with the groove of the pulley, and slide the timing pulley onto the camshaft with the plate washer and set bolt.
  11. Tighten the pulley set bolt to 40 ft. lbs. (54 Nm).
  12. Turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
  13. Finish installing the timing belt and check the valve timing, as follows:
    1. If reusing the old timing belt, align the matchmarks made previously and install the timing belt onto the camshaft pulley.
    2. Align the marks on the timing belt with the marks on the camshaft pulley.
    3. Loosen the No. 1 idler pulley set bolt 1 / 2 turn.
    4. Turn the crankshaft pulley 2 complete revolutions TDC to TDC. ALWAYS turn the crankshaft CLOCKWISE. Check that the pulleys are still in alignment with the timing marks.
    5. If the No. 1 idler pulley uses a green tension spring, slowly turn the crankshaft pulley 1 7 / 8 revolutions, and align its groove with the mark at 45 degrees BTDC (for the No. 1 cylinder) of the No. 1 timing belt cover.
    6. Tighten the No. 1 idler pulley set bolt to 31 ft. lbs. (42 Nm).
    7. Be sure there is belt tension between the crankshaft and camshaft timing pulleys.
  14. Place the right-hand engine mounting bracket in position but do not install the bolts.
  15. Install the upper (No. 2) timing cover with a new gasket(s).
  16. Remove the engine crankshaft pulley bolt and pulley.
  17. Using SST 09249-63010, or equivalent, install the mounting bolts for the right-hand mounting bracket. Tighten the mounting bolts to 38 ft. lbs. (52 Nm).
  18. Align the crankshaft pulley set key with the pulley key groove. Install the pulley. Tighten the pulley bolt to 80 ft. lbs. (108 Nm).
  19. Install the spark plugs.
  20. Install the right-hand mounting insulator, as follows:
    1. Attach the mounting insulator to the body and mounting bracket with the 4 bolts and 2 nuts.
    2. Tighten the 3 bolts to hold the mounting insulator to the body. Tighten the bolts to 47 ft. lbs. (64 Nm).
    3. Tighten the 2 nuts and bolt to hold the mounting insulator to the mounting bracket. Tighten the bolt to 27 ft. lbs. (37 Nm) and the nut to 38 ft. lbs. (52 Nm).
  21. Install and adjust the power steering pump drive belt.
  22. Install the right-hand engine undercover.
  23. Install the right front wheel.
  24. Lower the engine.
  25. If equipped, install the ABS actuator.
  26. Install the alternator and alternator bracket.
  27. Install the wiring harness bracket for the DLC1.
  28. Install the power steering reservoir bracket and reservoir.
  29. Connect the negative battery cable.
  30. Start the engine and check the timing.

step 13.4 is never to be skipped. ask why., most do. and it fails.

Can't keep the belt on my 1996 Dodge Grand Caravan. When it does stay on it squeals all the time. We have had this trouble for six years but it is getting worse. Replaced the belt twice in the last...


The belts on that year model are a known for this issue. As far as them popping off that indicates that they are too loose or too tight. Assuming you have never had any serious front end damage that caused damage to the pulley system between the different parts. The only other issue could be the pulley's being out of alignment or a weak tension pulley if you have the spring loaded tension arm that was used on some models. I know the 3.0 and 3.3 liter motors used them. The 4 cylinders used the adjusters on the alternator and AC brackets. If you have more than a 1/4 bend in the belt when it is in place the belt is too loose and will pop off. Make sure all the bolts for those devices you replaced are properly seated and the brackets are not moving around as well to be sure that is not an issue.

Went to change my alternator took off bolt attached to belt pullt bracket and can't seem to get the bracket back on .....HELP


Most cars have a spring loaded belt tensioner - look for a smooth pulley that the back of the belt goes around. If you removed the alternator mount without removing the belt first the tensioner spring will have taken up the slack and now you will not have enough latitude to refit the bracket. Make a sketch of the pulleys and the path the belt takes around them. Remove the belt. Refit the alternator bracket. Now focus your attention on the tensioner pulley. IN the middle of the pulley there will appear to be a bolt head, could be a torx. Fit the appropriate socket and with e wrench pull the nut and the pulley against the spring. It will take some effort but it will move. Once you have familiarised yourself with how the pulley moves it is now time to refit the belt. Using your earlier sketch as reference feed the belt over all the pulleys leaving the smallest until last, at which point the belt can be fitted over this by putting pressure against the tensioner pulley to provide the necessary slack. Easy when you know how

I have a audi i cant put the surpentine belt back in


Click on the following Direct Link. I know you said Serpentine (correct spelling) Belt and this Link has Timing Belt; however this does have the Serpentine Belt Diagram and also some key instructions to putting it back-on. After going to the Link, scroll down the page (to about half-way down the page) to Diagrams: G00039904, then G50H16367, then G50J16369.
In Diagram G00039904: it has the "Hinged Mounting Bracket" which has the Pulley holding tension on the belt keeping it tight. This must be loosened (NOT REMOVED) in order to get a serpentine belt back on. Then re-tightened in order to have the correct amount of tension.
In Diagram G50J16369: this Hinged Mounting Bracket has Mounting Bolts which again must be loosened (NOT REMOVED) in order for the hinge mounting bracket to move - loosening the Pulley = loosening the Serpentine Belt.
There are a couple of additonal Diagrams regarding the Electric Fan Mounting Bolts etc., that are useful for your reinstallation.

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!
