Before you adjust it, belts are on tighter than chains, 1/4 inch up and down play is norm

How do i adjust the drive belt on my troy bilt pony model 37120


There should be an adjusting nut you loosen somewhere along the belt path. You normally loosen it the pull the belt tight the tighten the nut back down much like a fan belt in a car.

How do you fit a new drive belt to a rockworth compressor because there doesn't seem to be ant adjustment


if this is a small compressor say 2 hp you leave everything alone make sure you have the right size belt and stretch it on like a rubber band.. The belt will be quite tight but thats the way they come. If you are concerned that the new belt is too tight or too loose mark the position of you motor with a felt pen remove the belt and move the motor forwards or backwards a small amount in line with your marks, then refit the belt. The main thing is that the motor shaft stays parrallel or close to it with the drive shaft of your pump.

Drive Belts

Print


INSPECTION

See Figures 1, 2, 3, 4 and 5
Check the condition and tension of all drive belts every 12,000 miles, or at least once a year. Loose drive belts can lead to poor engine cooling and diminished alternator, power steering pump, air conditioning compressor, or emission air pump output. A belt that is too tight places a strain on the bearings in the driven component.

Fig. Fig. 5: Installing too wide a belt can result in serious belt wear and/or breakage
Replace any drive belt that is glazed, worn, cracked, or stretched to the point where correct adjustment tension is impossible. If two belts are used to drive a component, always replace both belts when replacement is necessary. After installing a new belt, run the engine for ten minutes, shut OFF the engine and recheck the belt tension. Readjust if necessary.

Two popular methods of checking drive belt adjustment are; the Belt Tension Gauge Method and the Belt Deflection Method. The former requires a special gauge and the latter requires a straight edge and scale or just a good eye for measurement. The deflection method will be used in the following belt replacement instructions. A rule of thumb for checking belt tension by the deflection method is to determine the midpoint between two pulleys of the drive belt and press down at that point with moderate thumb pressure. The belt should deflect to the measurement indicated in the following installation procedures. Adjustment is necessary if the belt is either too loose or too tight.

WARNING A belt adjustment which is either too loose or too tight will eventually damage the accessory that belt is driving. A too loose adjustment allows free-play in the belt which could transfer a whipping motion or shock to the accessory drive pulley. Similarly, a belt which is too tight will preload the accessory bearings, leading to early failure.


REMOVAL & INSTALLATION

See Figure 11
Raise the front of the vehicle, support on jackstands and remove the lower splash shield if access is hampered due to space limitations when changing drive belts.

85 chevy celebrity. replaced alternator. that one squealed 2. got another. still hear a squeel. does not squeel when belt is off.


ALTERNATOR BELT NEED ADJUSTING AND REPLACING IT GLAZED. WHEN DRIVE BELT GET GLAZED SHINY CAUSE IT TO SLIP AND SQUEAL.REPLACE ALTERNATOR DRIVE BELT. AND ADJUST IT DRIVE BELT TENSION BY TIGHTEN THE UNTIL YOU CAN PRESS DOWN ON THE BELT IN THE LONGEST RUN. YOU NEED TO PRESS DOWN BELT AND GET A 1/4 TO 1/2 INCH DEFLECTION IN BELT.THE BELT CANT BE TOO TIGHT WHERE WHEN YOU PRESS DOWN AT IT WONT GIVE IN NONE TOO TIGHT, WILL CAUSE PREMATURE ALTERNATOR BEARING FAILURE IF DRIVE BELT TOO TIGHT.

Can i adjust accesory belt tension without a guage?


Serpentine belts?....yes. Absolutely. Timing belts...no. Drive belts should be tight, but not too tight. If too tight, it could cause noise because of the pressure put on the affected pulley bearings. Too loose can cause poor charging of the alternator, lose of power steering when the wheel is cut to much either way, or squeeling.

Belt routing


V-BELT ADJUSTMENT CAUTION
On models equipped with an electric cooling fan, disconnect the negative battery cable or fan motor wiring harness connector before replacing or adjusting drive belts. The fan may come on, under certain circumstances, even though the ignition is OFF. Alternator Drive Belt
  1. Position a ruler perpendicular to the drive belt at its longest run. Test the tightness of the belt by pressing it firmly with your thumb. The deflection should not exceed 1?4 in. (6mm).
  2. If the deflection exceeds 1?4 in. (6mm), loosen the alternator mounting and adjusting arm bolts.
  3. On 1968-72 V8 and 6 cylinder models, use a prytool to move the alternator toward or away from the engine until the proper tension is reached. NOTE: Apply tension to the front of the alternator only. Positioning the prytool against the rear end housing will damage the alternator.
  4. On 1973 and later V8 models, place a 1 in. (25.4mm) open-end or equivalent wrench on the adjusting arm bolt and pull on the wrench until the proper tension is achieved.
  5. Holding the alternator in place, tighten the adjusting arm bolt. Inspect the belt tension. When the belt is properly tensioned, tighten the alternator mounting bolt. Fig. 1: Alternator belt adjustment 86651054.gif
Power Steering Drive Belt ALL 6-CYLINDER AND 1971-72 V8 MODELS
  1. Holding a ruler perpendicular to the drive belt at its longest run, test the tightness of the belt by pressing it firmly with your thumb. The deflection should not exceed 1?4 in. (6mm).
  2. To adjust the belt tension, loosen the adjusting and mounting bolts on the front face of the steering pump cover plate (hub side).
  3. Using a prytool on the pump hub, move the power steering pump toward or away from the engine until the proper tension is reached. Do not pry against the reservoir as it is relatively soft and easily deformed.
  4. Hold the pump in place, tighten the adjusting arm bolt and then inspect the belt tension. When the belt is properly tensioned tighten the mounting bolts.
1973 AND LATER V8 MODELS
  1. Position a ruler perpendicular to the drive belt at its longest run. Test the tightness of the belt by pressing it firmly with your thumb. The deflection should be about 1?4 in. (6mm).
  2. To adjust the belt tension, loosen the three bolts in the three elongated adjusting slots at the power steering pump attaching bracket.
  3. Turn the steering pump drive belt adjusting nut as required until the proper deflection is obtained. Turning the adjusting nut clockwise will increase tension and decrease deflection; counterclockwise will decrease tension and increase deflection.
  4. Without disturbing the pump, tighten the three attaching bolts. Fig. 2: Power steering belt adjustment (slider type) 86651055.gif
Air Conditioning Compressor Drive Belt
  1. Position a ruler perpendicular to the drive belt at its longest run. Test the tightness of the belt by pressing it firmly with your thumb. The deflection should not exceed 1?4 in. (6mm).
  2. If the engine is equipped with an idler pulley, loosen the idler pulley adjusting boot, insert a prytool 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 adjust, as outlined under Alternator Drive Belt.
  3. When the proper tension is reached, tighten the idler pulley adjusting bolt (if so equipped) or the alternator adjusting and mounting bolts. Fig. 3: Air conditioning belt adjustment 86651056.gif
Thermactor® Air Pump Drive Belt
  1. Position a ruler perpendicular to the drive belt at its longest run. Test the tightness of the belt by pressing it firmly with your thumb. The deflection should be about 1?4 in. (6mm).
  2. To adjust the belt tension, loosen the adjusting arm bolt slightly. If necessary, also loosen the mounting belt slightly.
  3. Using a prytool, pry against the pump rear cover to move the pump toward or away from the engine as necessary. WARNING
    Do not pry against the pump housing itself, as damage to the housing may result.
  4. Holding the pump in place, tighten the adjusting arm bolt and recheck the tension. When the belt is properly tensioned, tighten the mounting bolt. Fig. 4: Air pump adjustment points 86651057.gif

My nordic track treadmill's walking belt stops when I start walking on it but the motor is still running although the front roller is not moving when I start walking on the walking belt. Do you think the...


Unplug the unit remove the motor shroud inspect the drive belt if the rubber feel slick then my recommendation is to replace the drive belt. Adjusting the drive belt may take care of the problem if you do not need to adjust it too tight. If you choose to do the adjusting and feel you have adjusted the running belt thinking it would resolve the slipping, then back the tension down until it the running belt is slipping then adjust until the slippage is resolved.

If I stand on the belt it stops moving


Unplug unit remove motor shroud so you can see the drive belt, plug in unit then start it you will be able to see whether the drive belt or running is actually causing the problem.If it is the running belt then turn both rear roller adjustment bolts clockwise in equal quarter turn increments until treadbelt stops slipping. NOTE: Be sure to run on treadbelt to ensure that the treadbelt does not slip while under load. Use 1/4" allen wrench
If the drive belt is slipping then to adjust the belt you must loosen the adjusting bolt on the motor frame then hold the motor by hand applied tension to belt then tight bolt you should be able to twist the drive belt no more then 45 degrees if you can repeat adjusting process.

Change drive belt //


check this out 02bdcd0.jpg
loosen the the two bolts (show on the figure above) first
loosen also the bolt used for adjusting tension.
remove the old worn-out belt.
place the new belt (you may need to loosen further the tension adjusting bolt)
when belt is properly place, tighten it enough the tension adjusting bolt,
(not too tight, but not too loose) press the belt to ensure its not too loose!
When belt tightness is enough, tighten the the other lower one of the two bolt then the lastly tighten the pivot bolt.
gookluck!!!!
