The inspection of drive belts hence calls for assessing its condition for glaze or crack by examination with a glazed belt showing slippage and cracked belts usually initiating on the inner side. Any worn out or damaged drive belt should be replaced in time while it is good practice to replace them all together as part of preventive maintenance. Manually adjusted belts need their tension and state checked every year with thumb pressure midway between pulleys used to assess tension. The belts should deflect correctly without sagging or having too much tension. The gap between outer surface to inner radial cracks must be watched, and course, cross-hatched driving surfaces are needed; the presence of very smooth surface means that there is belt slippage. In V-belts adjustment requires a locknut loosened, moving the component to obtain proper tension and retightening, whereas a multi-ribbed V-belt can be adjusted by loosening its pivot bolt then rotating the tensioning roller. Serpentine belts have automatic tensioners; therefore manual adjustment is not possible. Marking their direction of rotation when replacing belts is indispensable. When changing V-belts, loosen the adjustment bolt and pivot bolt so as to put them back at once afterwards. There are toothed bolts included in some components which make prying unnecessary. Proper routing needs to be done for multi-ribbed V-belts while tension is adjusted by rotating clockwise or anticlockwise depending on whether you want tightening or slackening respectively until desired level of tightness has been achieved after which one tightens up on his pivot bolt for his tensioner roller as per those words, For serpentine belts, they must fit correctly exactly same way as when fitted before if it happens again during spring-loaded tensioner assembly though, this can pose danger too-so much misplacement as these things keep making progress with. In case of air conditioner belts the methods of releasing tension will always be different depending on what kind of tensioners are being used whilst timing belts ought to be checked regularly and replaced if damaged, contaminated, removed for any reason or whenever their replacement period is not clear which generally happens after 50,000 miles or 4 years.
