The Complete Guide to Buying Chainsaw Parts and Accessories

Owning a chainsaw for either personal or business use can be very useful, but there are times when various parts and accessories may need to be replaced. It is of vital importance that a chainsaw is kept in top condition so that it performs at its best and the risk of malfunction or serious injury to the operator is reduced. An important part of keeping a chainsaw is knowing how to maintain it, and to be able to do this the owner will need to be familiar with the various parts and accessories. When purchasing chainsaw parts, make sure sufficient research is done into the make of tool and compatible parts. Always use a reputable seller on eBay with high-quality parts.

Chainsaw Parts and Accessories


Chainsaw chains should be replaced on a regular basis, ideally after 1-2 hours of use. When replacing a chainsaw chain, it is very important to make sure the correct measurements, size and type, since chains are available in almost limitless variations. This is because chainsaws themselves vary in size and application. When replacing a chainsaw chain, there are three different chainsaw chain numbers that must be known in order to find the right one for the chainsaw owned. These three numbers are:

  • Pitch
  • Gauge
  • Number of Drive Links


The pitch of a chainsaw chain is the measurement of how close the links are on the chain. It is measured by finding the distance between any three rivets on the chain, divided by half. This may sound complicated but the majority of chainsaws will display this measurement somewhere on the tool itself or in the operator’s manual. The most common chain size is 3/8” . When the pitch size is displayed on a chainsaw, it is usually found on the guide bar (towards the operator’s end of the tool). Sometimes it is very clearly displayed, but sometimes it is hidden amongst other numbers, so it is worth knowing what to look out for. If the pitch number can’t be found either on the tool or in the operator manual, it is usually best to take the chainsaw into a professional shop to be measured. The pitch can be measured at home, but a high level of accuracy is needed. If measuring at home, always remember to measure the central point of three rivets on the chain and then divide the number by two.


The parts of the chainsaw chain that fit into the guide bar are called drive links. The drive links are the bottom part of the chainsaw chain. The gauge is measured by the thickness of the drive links when viewed along the length of the chain. The right chain gauge is needed or the chain will not fit into the saw correctly. The most common gauge is .050”. Like the pitch measurement, gauge can also sometimes be found on the chainsaw itself amongst other numbers, so it is worth knowing what to look for. Because the difference between gauge measurements is so tiny, it is not recommended that the operator measure it themselves unless the measurement can be found either on the tool itself or in the operator manual. Ideally take the tool to a professional shop.

Number of drive links

The total number of drive links on the chain must be counted (if not already known). Overall length measurements are not what is required here, but the overall numbers of chain links. This is not a measurement that will be found on the tool itself, which is why the links need to be counted.

Sharpening and Filing Tools

These are vital as they help extend the life of the chainsaw. Sharpening the chainsaw when it is necessary to do so will make crosscutting easier to do, as it makes the chainsaw more efficient at cutting and shortens the time it takes to finish a project. This, in turn, reduces the chance of an accident occurring. The answer to this is to purchase a chainsaw file kit. The benefit of purchasing such a product is that it will add to the life of the machine and save money long term. This type of kit usually includes a round file, file handle, flat file, file handle, and guide. A depth guide gauge is also recommended but will normally need to be purchased separately.

Oil Pump

The oil pump of a chainsaw provides the lubricating oil to the guide bar, thus lubricating the chain. In order for the chain to keep running properly, oil must be supplied constantly, as there is a lot of friction involved and lack of oil can cause the chain to either stop or break altogether. If there is a lack of oil supply, then the oil pump will require replacement.

Spark Plug

Ideally chainsaw spark plugs should be changed after about 40 hours of use.

Chainsaw bar

The chainsaw bar should be replaced if it becomes warped, the groove is damaged or if the nose sprocket doesn’t turn freely.

Clutch Sprocket

The sprocket on a chainsaw is the piece beneath the clutch that drives the chain. When it is worn down, the chainsaw performance reduces, and the chain will start to slit or refuse to spin. This is when the clutch sprocket will require replacement.


A broken starter can be very frustrating for the chainsaw operator. The rope could snap, or refuse to recoil mid-project, and the common culprit could be that a new pulley or starter spring is required.

Other Parts and Accessories That May Also Require Replacement

Chain catcher – This is a metal or plastic guard which is design to prevent a chain that is broken or derailed from hitting the operator. Flywheel – This is a weighted wheel that controls the chainsaw engine speed and helps to cool down the engine. Clutch – This controls the driving part of the saw. Decompression Valve – This releases the saw compression which allows the chainsaw to begin easily. Anti-vibration handle system – Lessens the effect of vibration on an operator’s hands, arms, and upper body. Hand guard – This is a defensive plastic shield that protects the operator’s hands in case of kickback (which is where the nose of the chain or guide bar catches on wood without cutting it and throws the chainsaw violently backwards or upwards, which can be extremely dangerous). Muffler&– A hearing protection device that lessens the noise of the chainsaw when in use. Chain brake – A safety requirement that stops the chain if kickback occurs to prevent user injury. Throttle – This regulates the saw’s speed by increasing or decreasing the amount of fuel sent to the cylinders. When pressure on the throttle is released, the chain will stop. Throttle Interlock – Prevents the throttle from operating until the interlock is pressed.

What to Look Out For

Always make sure that the correct parts for the chainsaw are purchased. Some manufacturers’ parts are not compatible with others, so before making any purchase always make sure that the part will be able to be used with the chainsaw.
