Hi and welcome to FixYa, I am Kelly

This is a generic response to all John Deere Variator linkages but most likely what you must do with a transmission change.

To adjust the "Variator linkage" do the following.
1. Pry off the buttons on the side that cover the access holes located just below the variable speed lever.
2. Put the variable speed lever in notch #5.
3. Loosen cap screw one or two turns. This is located inside the hole.
4. Disconnect and ground the spark plug.
5. Turn ignition key to crank engine until clutch-brake pedal raises as high as it will go.
6. Take up linkage slack by pushing down on cap screw (see step #2). Tighten cap screw.
NOTE: If the tractor won't move with the variator in the first notch after these adjustments then the primary drive belt needs to be replaced.

I am concerned that maybe you did not connect the linkage properly but you have to do the above steps if no matter what you do you only have slow speeds.

I hear that on the service manual and the springs. Take a look at these decks if you talking about a deck belt and find yours. Then look for the spring routing visually.

http://opebycrigby.tripod.com/decks/jddeck.html

If you need drive belt info look here:

I would like to know if this was enough info for you so that you were able to re-connect the spring.

Thanks for choosing FixYa,

How to adjust tension on belt of John Deere Ride On D140


How to adjusted Cutting Deck Belt Tension

You do not say which size cutting deck you have. I will be writing about the 48", 3 blade cutting deck

The belt on this deck is self tensioned. The tension is provided by a spring attached to a moveable pulley on the deck. When the belt is in place you can manually force this pulley forward/backward and it will release the tension.

If the belt is off track, place the belt back around all the pulleys in the correct path, lastly force this spring loaded pulley forward/backward (depending on your deck, the direction is not important, the tension is) to get the belt around the pulley. If the belt is placed correctly, when you release the spring loaded pulley it will properly tension the belt.

Typically, these belts should not be jumping off. If yours is coming off frequently the belt may be worn. When they wear they get quite a bit longer, then the tension pulley cannot apply the correct tension. Rarely does the tension spring have to be replaced.

The other problem that causes belt jumping is worn spindles and stationary pulleys. The spindles are the most likely to need replacement. You can buy excellent replacements for JD spindles on Amazon for very reasonable prices. The following spindles are super replacement spindles for the 48" deck. They may very well be the same for smaller and larger decks; I have not researched that. Just search Amazon for Silver Streak # 285851.

How do i tighten the timing belt tension on a 1999 dodge stratus


The belt tensioner is not adjustable. To loosen a tensioner you would swivel the belt tensioner away from the belt with a long flex wrench or ratchet and to tighten the belt you would let the spring in the tensioner move the swivel back into the tight position. An internal spring tightens the tensioner pulley against the belt. You will need to get a smaller belt or replace the tensioner if the belt is "too loose" after you swivel it back into the tight position against the belt and release pressure.

How do i remove the timing belt tensioner without the proper tool?


TO LOOSEN THE BELT TENSIONER PULLEY ASSEMBLY, THEN POSITION A CAMSHAFT BELT ADJUSTER TOOL T74P-6254-A OR EQUIVALENT ON THE TENSION SPRING ROLL PIN AND RETRACT THE BELT TENSIONER AWAY FROM THE TIMING BELT.TIGHTEN THE ADJUSTMENT BOLT TO LOCK THE TENSIONER IN THE RETRACTED POSITION. INSTALL NEW TIMING OVER THE CRANKSHAFT SPROCKET AND THEN COUNTERCLOCKWISE OVER THE AUXILIARY AND CAMSHAFT SPROCKETS MAKING SURE THE LUGS ON THE BELT PROPERLY ENGAGE THE SPROCKET TEETH ON THE PULLEYS. BECAREFUL NOT TO ROTATE THE PULLEYS WHEN INSTALLING THE BELT.RELEASE THE TIMING BELT TENSIONER PULLEY ALLOWING THE TENSIONER TO TAKE UP THE SLACK. IF THE SPRING DOES NOT HAVE ENOUGH TENSION TO MOVE THE ROLLER AGAINST THE BELT.AND BELT HANGS LOOSE, IT MIGHT BE NECESSARY TO MANUALLY PUSH THE ROLLER AGAINST THE BELT AND TIGHTEN THE BOLT. YOU WILL NEED BELT TENSIONER TOOL OR EQUIVALENT.YOU CAN GO ON LINE INTERNET FIND THE BELT TENSIONER TOOL.SHOULD COST TOO MUCH.YOU CAN SEE IF AUTO ZONE HAS ONE TO RENT YOU.

Timing belt


TIMING BELT & SPROCKETS R & I
NOTE: Some procedures may differ slightly due to engine
construction.
Removal
1) Remove all necessary air ducts. Position No. 4 piston at
TDC of compression stroke. Align timing marks. See Fig. 2. Remove fan
and fan shroud. Remove belts. If necessary, remove radiator and
splashguard.
2) Prevent engine from rotating and remove crankshaft timing
pulley retaining bolt. Remove upper and lower timing belt covers.
Remove spring from tension pulley. Loosen adjusting bolt and move
pulley toward water pump. Remove timing belt.
CAUTION: Ensure pistons are at TDC when rotating camshaft or damage
may result.
Inspection
1) Handle timing belt carefully. Avoid twisting or kinking
belt. Do not allow belt to become contaminated by water, oil, dirt or
other contaminates. Inspect belt for cracks or damage. If necessary,
replace.
2) Measure tension pulley spring length and force. Spring
length should not exceed 2.76" (70.2 mm) and spring force should not
be less than 197-347 lbs. (27-48 kg).
3) Replace tension pulley spring if not within specification.
Installation
1) Pull tensioner fully toward water pump side and
temporarily tighten retaining bolt. Ensure No. 4 cylinder is at TDC on
compression stroke by rotating crankshaft until keyway aligns with
mark on front crankshaft seal housing (12 o'clock). Rotate camshaft
until timing mark on cam gear (arrow) aligns with mark on upper
camshaft cover (notch). See Fig. 2.
NOTE: When timing marks are aligned as stated above, No. 4 piston
is at TDC on compression stroke.
2) Position timing belt over crankshaft sprocket, oil pump
sprocket, camshaft sprocket and tensioner in that order. Ensure belt
is positioned in sequence given and without slack between sprockets.
Loosen tension sprocket adjusting bolt allowing spring tension to
tighten belt. Tighten adjusting bolt temporarily.
3) Temporarily install crankshaft pulley bolt and rotate
crankshaft 2 complete revolutions in opposite direction of engine
rotation, until marks on crankshaft and front oil seal retainer are
aligned again. See Fig. 2. Loosen tensioner lock bolt, allowing
tesioner spring to fully adjust tension. Tighten tensioner lock bolt.
4) Install timing belt covers. To complete installation,
reverse removal procedures. Tighten all bolts to specification. See
TORQUE SPECIFICATIONS table at end of this article.

Changing the timing belt on a Hundai


  1. Remove all necessary components for access to the timing belt cover, then remove the cover.
  2. Rotate the crankshaft clockwise and align the timing marks so No. 1 piston will be at Top Dead Center (TDC) of the compression stroke.
  3. Loosen the tensioning bolt and the pivot bolt on the timing belt tensioner. Move the tensioner as far as it will go toward the water pump. Tighten the adjusting bolt.
  4. Mark the timing belt with an arrow showing direction of rotation.
  5. Remove the timing belt.
  6. If defective, remove the timing belt tensioner.
  7. Align the timing marks of the camshaft sprocket and check that the crankshaft timing marks are still in alignment.
  8. If removed, install the timing belt tensioner, spring and spacer with the bottom end of the spring free. Tighten the adjusting bolt slightly with the tensioner moved as far as possible away from the water pump.
  9. Install the free end of the spring into the locating tang on the front case.
  10. Position the timing belt over the crankshaft sprocket, then over the camshaft sprocket. Slip the back of the belt over the tensioner wheel.
  11. Turn the camshaft sprocket in the opposite of its normal direction of rotation until the straight side of the belt is tight and be sure the timing marks align.
    NOTE If the timing marks are not properly aligned, shift the belt 1 tooth at a time in the appropriate direction until they are aligned.
  12. Loosen the tensioner mounting bolts so the tensioner works, without the interference of any friction, under spring pressure. Be sure the belt follows the curve of the camshaft pulley so the teeth are engaged all the way around. Correct the path of the belt, if necessary.
  13. Tighten the tensioner adjusting bolt, then the tensioner pivot bolt to 15-18 ft. lbs. (20-26 Nm).
    NOTE Bolts must be tightened in the stated order or tension won't be correct.
  14. Turn the crankshaft 1 turn clockwise until timing marks again align to seat the belt.
  15. Loosen both tensioner attaching bolts and let the tensioner position itself under spring tension. Retighten the bolts.
  16. Check belt tension by putting a finger on the water pump side of the tensioner wheel and pull the belt toward the water pump. The belt should move toward the pump until the teeth are approximately 1 / 2 of the way across the head of the tensioner adjusting bolt. Re-tension the belt, if necessary.
  17. Install the timing belt covers and all other related components.

Drive belt adjustment


most belts are tightened by an idler pulley, which is either controlled by
1) the operator moving or sqeeqing a lever (this type of system may have a cable adjustment)

2) and/or a tensioner spring tightened idler pulley
no adjustment is required

3) if the belt is still too loose, and new belt may be required

Drive belt slips on lawn tractor, cannot see an adjustment.


hi,

i would check with the owners manual to see if it shows an adjustment for the belt drive. most mowers today are equipped with a self adjusting arm witha pulley tensioner with a spring attatched to it. as the belt stretches the tensioner spring pulls against the arm causing it to apply tension to the belt thus tightening it. it sounds as if your belt is stretched beyond the limits of the tensioner. at least every new season it would be a good idea to inspect the belt tensioner for room or space of free play. that is to check to see if it will move opposite the pulley allowing the belt to tighten. if there is not enough sufficient room then i suggest replacement of the drive belt.

  1. REMOVAL
    AIR CONDITIONING BELT

    NOTE: The A/C drive belt self tensioner is NOT a dynamic tensioner. After adjustment the tensioner bracket bolts are tightened. The torsion spring is no longer responsible for tensioning the A/C belt. The torsion spring is only used for initial belt tensioning.
    1. Remove generator/power steering belt to gain access to A/C belt. Refer to GENERATOR/POWER STEERING BELT for procedure.

    1. Loosen BUT DO NOT REMOVE tensioner locking bolt and pivot bolt (Fig. 2).
    2. Insert 1/2" drive breaker bar into square opening on belt tensioner. Rotate tensioner counterclockwise until belt can be removed from pulleys (Fig. 2).
    3. Slowly rotate tensioner clockwise to relieve spring load.
    CLEANING
    Clean all foreign debris from belt pulley grooves. The belt pulleys must be free of oil, grease, and coolants before installing the drive belt.

    INSPECTION
    Belt replacement under any or all of the following conditions is required:
    • Excessive wear
    • Frayed cords
    • Severe glazing
  • Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not (Fig. 3).

    NOTE:
    Do not use any type of belt dressing or restorer on Poly-V Belts. INSTALLATION

    WARNING: DO NOT REMOVE A/C BELT TENSIONER LOCKING BOLT WITHOUT FIRST HOLDING THE TENSIONER WITH A 1/2" DRIVE BREAKER BAR, AS PERSONAL INJURY COULD RESULT.
NOTE: Verify that torsion spring position is in the new belt position before installing a NEW belt (Fig. 4). If torsion spring is not in the new belt position, follow steps 1-7 to change the tensioner spring from the USED belt position to the NEW belt position.
  1. Insert a 1/2" drive breaker bar into the square opening on the tensioner. Hold counterclockwise pressure on tensioner while removing the locking bolt (Fig. 2).
  2. Carefully release spring load of the torsion spring on the tensioner.
  3. Remove pivot bolt, tensioner, and spring from front timing cover.
  4. Insert spring arm into the NEW belt position on the tensioner (Fig. 4).
  5. Install torsion spring, tensioner, and pivot bolt.
  6. Install pivot bolt. Tighten only finger tight, at this time.
  7. Using a 1/2" drive breaker bar, apply counterclockwise pressure until locking bolt can be installed.
    1. Install the NEW belt by rotating the tensioner counterclockwise until the NEW belt can be installed on pulleys. See (Fig. 5) for belt routing.
    2. Release tensioner and remove breaker bar. Belt is automatically adjusted with the tensioner's torsion spring.
    3. Tighten tensioner locking bolt and pivot bolt to 28 Nm (250 in. lbs.) (Fig. 2).
    4. Install generator/power steering belt.
    AIR CONDITIONING BELT - USED

    NOTE: A "used belt" is considered having more than 500 miles of service use. NOTE: Perform steps 1-7 to change the tensioner spring from the NEW belt position, to the USED belt position.
    1. Insert a 1/2" drive breaker bar into the square opening on tensioner. Hold counterclockwise pressure on tensioner, while removing tensioner locking bolt (Fig. 2).
    2. Carefully release the tension of spring on tensioner.
    3. Remove pivot bolt, tensioner, and spring from front cover.
    4. Insert spring into the USED belt position on tensioner bracket (Fig. 4).
    5. Install spring, tensioner bracket, and pivot bolt.
    6. Install pivot bolt. Tighten only finger tight, at this time.
    7. Using a 1/2" drive breaker bar, apply counterclockwise pressure until locking bolt can be installed.
    8. Install the USED belt by rotating tensioner counterclockwise until belt can be installed on pulleys. See (Fig. 5) for belt routing.
    9. Release tensioner and remove breaker bar. Belt is automatically adjusted with the tensioner's torsion spring.
