The alternator is sitting on a guide. It is held on it by a bolt. All you have to do is loosen that bolt and the belt pressure sould realese.
Look around for a wheel that is touching the belt but appears to have no other purpose...this is the tensioner. Use a long handled wrench on the nut in the middle of the tensioner.
there should be a diagram under the hood, in front of the radiator, that will show belt routing and show where the tensioner is...
You can loosen the tension on your alternator belt by loosening the tensioner bolt. When the tensioner bolt is loose you can slide the alternator to the left.
Loosen the tensioner pulley. The tensioner pulley will slide to the right. This will loosen the alternator belt. So it can be removed.
find the tensioner pulley to release the belt. there should be two bolts on the top (one in front, one in rear) and one on the bottom rear ( this one is very tricky to get to).
There are two serpentine belts a/c timing etc. and alternator just release belt tensioner towards front of motor for outer belt and the secnd tensioner is located on the alternator
im going on the assumption that you are referring to the belt back on the tensioner cause there is no reason to remove the tensioner to install an alt. if it is a matter of putting the belt on, make sure that the belt is routed correctly through the pulleys. then remove the belt off the alternator, put the belt on the tensioner THEN pull the tensioner back with a wrench on the tensoiner adjusting nut. slip the belt on the alternator and slowly release the wrench. i hope this was helpful
If it's the timing belt tensioner then you have to loosen the tensioner bolt and then use a 1/4 inch hex bit and turn the tensioner clock wise. Be sure to turn the tensioner only counter clockwise to retension and align the 2 pointers. The alternator or serpentine belt tensioner requires a 13 mm wrench to turn the tensioner counter clockwise to release the tension.
first unhook the battery, then release the automatic belt tensioner and remove the belt, then unbolt the alternator and disconnect the wiring from the alternator....to reinstall, reverse the removal procedure
Use a tensioner tool or wrech if you can to pull the tensioner so the belt loosens. thread in the new belt and release the tensioner to tighten the belt. Belt diagram is usually in the engine compartment
put a wrench on the pulley side of the tensioner (15mm?) and turn. The pulley arm will move & loosen up the belt.
the belt tensioner is mounted to the block if you are trying to change the tensioner tou have to remove the alternator.if you are trying to change the belt it is the pulley to the left of the alternator it takes a 15mm wrench which you have to pull upwards to release tension
Note:The drivebelt routing decal on the radiator shroud to help during drivebelt install * To replace the belt rotate the tensioner pulley clockwise to release belt tension * Remove the belt from the auxiliary components and slowly release the tensioner * Route the new belt over the various pulleys again rotating the tensioner to allow the belt to be installed then release the belt tensioner
To change the alternator drive belt on a Bobcat 853 you start by lifting the cab. With the cab up, you can see the back of the engine and alternator. Locate the belts spring tensioner and release the belt.
Release tension at automatic tensioner use a breaker bar and socket
use a breaker bar to release pressure on automatic belt tensioner
Move the tensioner to release belt (use bolt in center of pulley and move with socket) Then simply remove bolts from block. Reverse to put on new one.
stick a 1/2 inch socketteless ratchet in it and pull it should be down and to the left of the alternator feed
Look for the tensioner pulley. There are threads on the tensioner arm that you have to put a bolt into. Turn the bolt and the tensioner will loosen. The belt will slide off. Put the new one on and remove the bolt in the tensioner. 2: I personally use a pair of vise grip and pry the tensionner arm
Disconnect the battery. Make a drawing of the belt routing. locate the belt tensioner pully and release enough belt pressure so a cohort can remove the serpentine belt off the closest pully. Remove the bolted on battery cable and electrical plug from the alternator and the mounting bolts or remove the bolts so you can access the electrical connection. Remove the ALT. Reverse the procedure to install your new alt. You will have to move the tensioner again to get the belt back on that last pulley.
If you completely replaced the serpentine belt you must detach the right side of the engine from its mount in order to get the belt back on its path illustrated on the engine's right side. If you are not replacing the belt and just want to slip it back on, then, just release the tension on the tensioner pulley near the rear of the engine and slip the belt back onto the tensioner pulley.
Remove Battery Negative Cable & secure away from post. Release tension on Belt Tensioner & remove Serpentine Belt from Alternator Pulley. Remove Battery Cable & Electrical Plug from Alternator. If applicable, remove Power Steering Line Clip from Alternator. Remove Alternator Mounting Bolts. Remove Alternator. Installation is reverse.....
If it is a drive belt and not a serpentine belt is has no tensioner. You manually adjust the tension by normally adjusting tension by moving the alternator. Loosen to bolts holding the alternator in place and then adjust the tension. Tighten the bolts when the tension is right. If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.
You have to use a 1/2 inch breaker bar and put it in the square hole of the tensioner and turn it to release the tension of the belt.
There are three main steps behind replacing the alternator on the 1998 Chrysler Concorde. The first is disconnecting the battery cables for safety. Second, is depressing the belt tensioner to allow for the release of the drive belt. Finally the alternator can be unbolted from its bracket for replacement. If the drive belt, idler pulley and tensioner are worn it would be an ideal time to replace this components as part of the install.
Disconnect the NEGATIVE battery cable at battery.Then you will have to release the tension on the serpentine belt there is a belt tensioner that requires a 22mm wrench to release the belt.Then disconnect wire HARNESS CONNECTOR on back of alternator & remove mounting bolts.Assemble in reverse order.
Disconnect battery cables at battery. Remove serpentine belt by using a breaker bar to release the tension. Use the opening in the tensioner pulley bracket. Disconnect alternator. Pretty simple. www.trailvoy.com
