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. 1: There are typically 3 types of accessory drive belts found on vehicles today

Fig. Fig. 2: An example of a healthy drive belt

Fig. Fig. 3: Deep cracks in this belt will cause flex, building up heat that will eventually lead to belt failure

Fig. Fig. 4: The cover of this belt is worn, exposing the critical reinforcing cords to excessive wear

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.

ADJUSTMENT

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.

if you're refering to the serpentine drive belt, most are held tight with the tentioner & you will need a 3/8'' drive breaker bar to pull back on it & while doing so, remove the belt carefully & then gently releasing the tentioner. most have a square 3/8'' hole in the middle of it to insert the tool & is easier to remove from under the vehicle. hope this helps.

You can reuse it. But you need to find out why it was thrown off. Check all the pullies by grabbing them and checking for side to side movement, With the exception of the power steering pump pulley (which has some in and out play) they all should have no play. Just turn in nice smooth circles. Sorry I don't have the diagram, but there should be one under the hood. Sometimes on the bottom of the hood.

dont cut the belt try to tighten more to release it or unbolt

The serpentine belt tensioner has a 3/8 drive rachet square on it. By attaching a 3/8 drive rachet and a strong forearm, pry the tensioner back and slip the belt under it. At your local auto parts dealership, they sell a prybar with a 3/8 drive square that's welded to it if you don't have a strong forearm. This runs about $20. It might actually be easier to slip the belt under the belt tensioner. Prying the tensioner back and slipping the belt over the water pump pulley or power steering pump pulley.

There should be a tensioned idler pulley which has an internal spring to take up the slack. It will have a nut or a drive socket so you can attach a spanner and rotate it to relieve the tension. You will need an extension as the tension is quite high. Putting the belt back is easier with an extra person to hold the idler pulley back while you manipulate the belt.

on the underside of the belt is a patch mirror clean it , replace the cleaner

I have a manual for the Wizard 5HP tiller. The reverse belt basically makes a figure 8
The belt goes over the motor pulley and over the idler pulley then makes a twist in the middle and around the bottom pulley. This cause it to basically rotate the opposite direction from the rotation of the drive pulley

i can't give you a picture but i will say that you may just need to tighten the belt instead of replacing it. and if you don't want to spend the money on a chiltons repair book (sold at auto zone) then if you have a library close they carry them most of the times and you can just make a copy of the pages you need.
