car pulley belt

For decades, drive belts, V-belts, multi-vee-belts, and serpentine belts have been used to transmit power from the engine crankshaft pulley to add-ons, like the power steering pump, air-con compressor, water pump, or cooling fans. Toothed timing belts and timing chains, too, are used to transmit power from the crankshaft to the camshafts, plus some from the camshaft to camshaft, based on engine design.

The drive belt, timing belt, or timing chain won’t work very well, or for lengthy, if, with incorrect Car Pulley Belt tension. A loose drive belt won’t drive the accessory reliably, slipping and making noise. Conversely, an excessively restricted belt may cause item or pulley bearing harm. Various forms of tensioner pulley preserve long-term engine and item quietness and reliability.

Tightening or Loosening
Sometimes, maintenance or repair will require tightening or loosening a tensioner pulley. Replacing a drive belt or timing belt, for instance, would need you to loosen a tensioner pulley to make room for the new belt, as the brand new belt is smaller sized than the worn drive belt.

You will have to tighten a tensioner pulley, generally, after the installing a fresh drive belt, or to change for a stretched drive belt that hasn’t worn enough to warrant replacement. Extend belts don’t need tensioner pulleys but are “stretched” into place using a special tool-always use the special tool to avoid belt damage.

Tensioner pulleys generally fall into two categories: accessory-integrated (AI) and non-accessory-integrated (NAI). Think of AI tensioners as adjustable accessories, such as an alternator, and NAI tensioners as adjustable idler pulleys. There are three types of tensioner pulleys and many methods to loosen them.
Mechanical tensioner pulleys will be the simplest, the majority of common, and least prone to failure. There can be one caveat, however, as mechanical tensioner pulleys require manual adjustment. This makes them prone to user error, resulting in insufficient or excessive belt tension. Additionally, they have to be adjusted to compensate for belt stretch over time.
