Chainsaw parts can often present problems in respect to finding the right parts when they need to be replaced and many times, woodcutters can incur unnecessary espense by simply going out and buying a new chainsaw.

Preserving chainsaw parts comes down to good maintenance practices; maintaining and looking after your saw on a regular basis will ensure the vital components are preserved longer and will give you greater service. Ignore general maintenance and it not only becomes expensive and frustrating but safety issues can come into play.

When purchasing a chainsaw, it’s good practice to buy from a dealer which provides back up service and parts. For example, buying a Stihl saw from a Stihl dealer means specialist parts shouldn’t be a problem when they’re needed and the same goes for Husqvarna, Echo, Poulan and so on.

Dissecting a chainsaw’s parts means concentrating on a dozen or so aspects of a machine which combine to produce the overall work output. These are some of the parts which you need to pay special attention to during a chainsaw’s life.

- Chain catcher…this is a safety part which protects the user from being injured by a renegade saw chain.

- Anti-vibration… vibration can cause undue stress to a user’s arms and joints. Anti-vibration systems absorb much of the vibration output ensuring smoother handling.

- Chain brake… kickback is a common concern with chainsaw use and causes many accidents. The chain brake was introduced during the mid 90’s as a way of putting an effective stop to the chain if kickback occurs.

- Muffler… noise has always been associated with chainsaw use and the muffler assists in alleviating part of this problem by absorbing a good part of the noise thus having less impact on a users hearing.

Flywheel… this part has a two-pronged benefit as it not only controls the speed of the engine but also has coolant qualities. While powerful, chainsaws are not excessively big machines but produce enormous amounts of power. Heating could be a problem however, flywheels reduce a lot of the heat stress.

Other chainsaw parts include the clutch, decompression valves and throttle valves which all have an important part in the performance of the machine.

Maintenance of chainsaw parts should be done on a regular basis. Sharpening of a dull chain, checking the fuel system and making sure it’s clear of unwanted contaminants, checking the chain system for correct tension, air filters, spark plugs and making sure the muffler is clean and undamaged on a regular basis will all help to preserve the vital parts of a chainsaw.

Don’t forget, maintenance of chainsaw parts is not just about checking them regularly. When your machine is not in use, storage is also an important factor. If your machine is in limbo for any length of time, you’ll need to perform tasks such as draining the fuel tank as well as from the carby line and draining the machine’s oil. There are other areas you need to pay attention to which should be listed in your chainsaw service guide. The saw itself you be stored away from the elements.

Gasoline-powered vehicles such as your Pontiac are among the major contributors to urban air pollution. This can be attributed to the high quantities of nitrogen oxides, carbon monoxide and hydrocarbons that are being produced by the normal combustion process of your car. If these burnt gases are left uncontrolled, they would eventually contribute to urban smog, as well as heart and respiratory heart problems. To protect the air quality and improve the quality of air, your Pontiac vehicle has been equipped with a group of emission-control components known as the exhaust system. This group of car parts serves the main function of conveying burnt gases from your internal combustion engine. The Pontiac catalytic converter is an indispensable part of your exhaust system. It looks very much like the muffler, and can be usually seen mounted under the vehicle. It was first used in cars three decades ago, and has evolved into a more complex and more reliable emission control component because of automotive technology.

The number of catalytic converters installed on your vehicle depends on your car?s configurations. Some have 1 while others have 2 catalytic converters. But no matter how many catalytic converters you may have on your car, they still serve the same purpose?that is, to significantly minimize the harmful poisonous gases in your exhaust gases. A typical Pontiac catalytic converter is made up of a honeycomb form catalyst that is protected by a stainless steel canister. The interior surface of your Pontiac catalytic converter within the honeycomb structure is coated with catalytic metals such as rhodium, palladium, and platinum. There are 2 catalysts present in every catalytic converter?an oxidation catalyst and a reduction catalyst. The oxidation catalyst burns all the byproducts of your fuel combustion such as the carbon monoxide and hydrocarbons. On the other hand, the reduction catalyst ensures that the nitrogen oxides are turned into harmless emissions.

There are 2 types of catalytic converter: the two-way converter and the three-way converter. Also known as an oxidation catalytic converter, the two-way catalytic converter makes use of the oxidation process to transform the harmful pollutants into harmless gases. Through adsorption, the oxygen molecules, carbon monoxide, and hydrocarbon are simplified into water vapor and carbon dioxide, which eventually goes out of the tailpipe. The three-way catalytic converter oxidizes the hydrocarbons and carbon monoxides and at the same time transforms the nitrogen oxides into less harmful nitrogen and oxygen. This type of catalytic converter is used in conjunction with the feedback engine management and fuel injection of the car. Your Pontiac catalytic converter can last for over 100,000 miles if properly maintained. A worn out catalytic converter can decrease the performance level and fuel economy of your engine, aside from contributing to urban pollution and health problems. You can easily determine if your Pontiac catalytic converter needs replacement when you hear some rattling noises from the catalyst, especially when your car is increasing speed. A defective oxygen sensor and poor maintenance are some of the leading causes of a worn out catalytic converter. So when this happens, do not think twice on replacing your defective Pontiac catalytic converter with a new one in order to maintain the emission control functions of your car.
