One of the "wheels" that the belt goes around is also the tension adjustment. When loosened it moves down to release tension. You may have to push and hold it down as well. See the diagram at this link - it should provide you with the corect information. http://autorepair.about.com/library/images/bl869a-lib.htm
To loosen a tension pulley on a 1991 Chrysler New Yorker, turn the nut in the center of the pulley. This will allow the pulley to slide in the cut-out groove so that the belt will loosen.
To change the tension pulley on a 1993 Chrysler New Yorker, first, ensure the engine is off and cool. Locate the tensioner assembly, then use a wrench to rotate the tensioner arm counterclockwise to relieve tension on the serpentine belt. Remove the belt from the tension pulley, then unbolt the pulley from the tensioner assembly and replace it with the new pulley. Finally, reattach the belt, ensuring it's properly routed, and reapply tension to the belt by releasing the tensioner arm.
If it is a serpentine belt, the tension is automatically adjusted by the tension idler. If the belt is loose then the tensioner needs replacing. If it is a normal drive belt, then the alternator is mounted on a slotted bracket that allows you to adjust the position of the alternator. You can loosen the bolts and adjust the tension on the belt.
Assuming you have a serpentine belt on that 3.3L engine, the tension on the alternator would be controlled by the idler (tension) pulley. The alternator is stationary.
you dont,the tensioner tightens the belt up.if belt sqeals get new belt or tensioner! on 3.1v6,
Power steering/Drive belt Adjustment To adjust P/S belt tension, loosen tension pulley bolts and turn tension pulley using hexagon wrench. Adjust belt tension to specification described in CHECK. Then tighten tension pulley bolts to specified torque. Tightening torque P/S belt tension pulley bolt (a): 25 Nm (2.5 kgf-m, 18.5 ft. lbs.)
To replace the tension belt on your exercise bike, first, locate the tension knob and release the tension on the belt. Then, remove the side cover of the bike to access the belt. Loosen the bolts holding the belt in place and remove the old belt. Install the new belt in the same position and tighten the bolts. Finally, adjust the tension knob to the desired level and test the bike to ensure the belt is working properly.
I have a 1054 and just put a new drive belt on it. It has a spring loaded belt tension pulley and there is no adjustment. Check and see if the spring has broken or come off the pulley.
To replace the belt on your garage door opener, follow these steps: Unplug the opener and remove the cover to access the belt. Loosen the tension on the belt by adjusting the tensioner or pulley. Remove the old belt and install the new one in the same position. Adjust the tension on the new belt and make sure it is properly aligned. Replace the cover and plug in the opener to test the new belt.
To fit the alternator belt on a Frontera TDI, first, ensure the engine is off and cool. Loosen the tensioner bolt and adjust the tensioner to relieve tension on the old belt, then remove it. Route the new belt around the alternator and other pulleys according to the belt routing diagram, ensuring it sits correctly in the grooves. Finally, adjust the tension on the tensioner, tighten the tensioner bolt, and check the belt for proper alignment and tension before starting the engine.
To fit Mitsubishi Shogun fan belts, first, ensure the engine is off and cool. Loosen the tensioner bolt and adjust the tensioner to relieve tension on the old belt, then remove it. Install the new fan belt by routing it around the pulleys according to the belt diagram, ensuring it sits correctly in the grooves. Finally, adjust the tensioner to apply proper tension to the new belt and tighten the tensioner bolt.
To change the fan belt on a JCB 1400 backhoe, first, ensure the engine is off and cool. Remove the belt guard if applicable, then loosen the tensioner or adjust the idler pulley to relieve tension on the old belt. Remove the old belt and install the new one by routing it according to the belt path indicated on the machine. Finally, adjust the tension to the proper specifications and reattach the belt guard.
