Since the OAD, belt and tensioner are a system, it is a good idea to replace them together.

• Ultimately, this “mechanical virus” can damage other, more expensive, components within the belt drive system.
• Overrunning alternator pulleys and overrunning alternator decoupler pulleys are becoming increasingly popular on many late model vehicles due to increased alternator loads and engine torsional fluctuations.
• OADs are becoming the design of choice for many newer applications.
• industryresearch.biz has published a new research report on “Global Alternator Decoupler Pulleys Market” to its database.
• This report is aimed toward guiding people towards an apprehensive, better, and clearer knowledge of the market.

to absorb some of the force associated with belt tension application and release. During rapid deceleration, the OAD allows the alternator’s rotor to free-wheel, rather than cause a drag on the belt. So the OAD is consistently absorbing speed increases and deceleration reductions as you drive. That reduces belt wear and quiets the engine by reducing noise, vibration, and harshness.

Accessory Drive System Guide

This condition will likely lead to unsatisfactory levels of NVH and reduced component life. This clip shows the use of a variety of “one-way clutch” alternator pulleys on the same engine. Millions of late-model vehicles now require alternators equipped with an OVERRUNNING ALTERNATOR DECOUPLER™ (OAD™) pulley rather than conventional solid or “one-way clutch” pulleys.

Similarly, the use of an “OAP” (“one-way clutch”) on this application also results in significant belt drive vibration, causing NVH issues and wear of key components. Used to be the industry standard and has been around for many years. If your alternator has a solid pulley, only replace if damaged, rusted, or worn. Have the engine running at idle and check belt tensioner movement. If excessive, this may be the first indication of a worn overrunning alternator pulley. Multi-rib accessory drive belts were commonly made of neoprene and generally lasted about 50,000 miles, but since the mid-1990s, drive belts have been made of EDPM and can last up to 100,000 miles. The key words here are “up to.” Check the belt, tensioner and clutch pulley every 50,000 to 60,000 miles.

The internal torsion spring design is patented by Litens Automotive Group of Toronto, Canada. Replacement OAD pulleys are available from Gates, Veyance , Schaeffler and Advance Auto Parts. Key regions covered in the report are North America, Europe, Asia-Pacific and Latin America.

An alternator decoupler pulley drives the alternator by transferring torque from the engine to the alternator via the belt. It powers the alternator during acceleration and cruising speed, and it disengages during engine deceleration. Its job is to reduce the drive system vibrations, QuickBooks improve the engine efficiency and increase the life of the belt, tensioner and other parts. Global “Alternator Decoupler Pulleys Market” report covers all crucial aspects like growth factors, market developments, top investment opportunities, future prospects, and trends of industry.

Gates Pulley

I read your post above and thought that you had solved my problem– the decoupler on the alternator pulley was bad. As preventive maintenance replace the pulley when rebuilding the alternator and/or when replacing the serpentine belt.

A failure to install the correct replacement design could cause severe damage to a vehicle’s belt drive system. Compare the diameter of the alternator pulley to the diameter of the harmonic balancer and you’ll see that the alternator pulley is generally 1/3 the diameter of the balancer.

However, an Overrunning Alternator Pulley on the other hand, is just a one-way clutch that allows the alternator’s rotor to free-wheel during deceleration. Many late model vehicles are equipped with alternators fitted with an Overrunning Alternator Decoupler Pulley or simply, OAD. This condition will cause a loss of engine efficiency/fuel economy, shortened belt and bearing life, extreme NVH, and other problems. This footage shows a Litens OAD™ pulley on the same application. Note the smooth, efficient, low-stress operation of the belt drive system. This comparison of three leading alternator pulley designs demonstrates the danger of using the wrong type of pulley on a vehicle requiring an OAD™ pulley.

Alternator Decoupler Pulleys market competitive landscape provides details and data information by companies. The report offers comprehensive analysis and accurate statistics on revenue by the player. It also offers detailed analysis supported by reliable statistics on sale and revenue by players. Millions of vehicles are now factory-equipped with an OVERRUNNING ALTERNATOR DECOUPLER™ (OAD™) pulley rather than a conventional solid pulley or one-way clutch pulley.

Traditional pulleys, whether driven by a V-belt or multi-rib belt, are attached to the alternator with a nut. OAD pulleys have a flange on the front that sticks out past the belt grooves. OADs are attached to the alternator shaft with a bolt, usually an “Allen” or Torx type. You will need special tools to diagnose or replace these pulleys. These engines cash flow and the belt tensioners were designed for OAD pulleys and replacing it with another type of pulley can damage the belt, tensioner, and even the engine. This patented design offers exclusive benefits that cannot be provided by another type of pulley. Use of another type of pulley could lead to serious and expensive issues in the drive belt system.

The global market for trusted digital certificates is largely held by a small number of multinational companies. Certification authorities in the market use different validation techniques such as domain validation, extended validation, and organization validation. Commercial certification authorities often use a combination of techniques to assure the correctness. The certification authority market in influenced by a number of standards such as General Data Protection Regulation , Sarbanes-Oxley Act , and Payment Card Industry Data Security Standard .

These improvements are possible by utilizing Litens’ Lean System design philosophy. Lean systems, with only Litens’ OAD™, can significantly reduce the common parisitic losses found in accessory drives, due to the belt bending that occurs during operation. The parisitic loss reduction is a result of a holistic approach to accessory drive – drive layout, OAD™, and tensioner design/matching. This video demonstrates the excessive levels of NVH, belt system stress and other severe issues resulting from the use of a solid alternator pulley on this Ford engine. The OAD™ pulley is significantly different from any other “clutched” alternator pulley. Using another type of pulley in place of an OAD™ is a sure way to cause drive belt system problems. I’ve been told by many engineers what the purpose of these clutch pulleys are but it never holds up to annylasis.

This report provides a complete quantitative data and qualitative analysis on the global market for Alternator Decoupler Pulleys . Market size is analysed by country, product type, application, and competitors. Expanded coverage includes additional end-user industry breakdowns and in-depth producer profiles. I had an alternator decoupler pulley failure, a product I had never heard of until today. I did not locate a thread addressing these pulleys; so, I thought I’d start one to inform/help others. Now we see the smooth, efficient operation of the same engine belt drive system using an OAD™ pulley. The Liten OAD™ pulley was previously referred to as an isolating decoupler pulley or IDP and marketed under the RotorRX brand.

OAP’s often are found on automotive diesel engines that exhibit torsional vibration in the engine during running as well as during engine shut down. This is accomplished by using the one-way clutch that allows “freewheeling” one direction, but locked engagement the other rotational direction to drive the alternator. This freewheeling/locking feature’s function is what normally fails over time and requires replacement of the complete OAP. The OAD™ pulley design is patented by Litens Automotive Group, a global manufacturer of original equipment and replacement components for the transportation industry. Litens is also the exclusive manufacturer of OAD™ pulleys for original equipment alternator manufacturers as well as customers in the replacement parts market.
