The Stihl MS 170 is a popular lightweight chainsaw, perfect for homeowners and occasional users. However, like any piece of machinery, it requires occasional maintenance and may need parts replaced over time. Understanding where to find Stihl MS 170 parts and what parts are commonly replaced is crucial for keeping your chainsaw running smoothly. This guide will delve into everything you need to know about sourcing and identifying Stihl MS 170 chainsaw parts.
Where Can I Buy Stihl MS 170 Parts?
Finding replacement parts for your Stihl MS 170 chainsaw is relatively straightforward. Several options exist, each with its own advantages and disadvantages:
-
Authorized Stihl Dealers: This is generally the recommended option. Authorized dealers offer genuine Stihl parts, guaranteeing quality and fit. They can also offer expert advice on part identification and installation. However, they may be slightly more expensive than other options.
-
Online Retailers: Numerous online retailers sell Stihl parts, often at competitive prices. Be cautious and ensure you're buying from a reputable seller to avoid counterfeit parts. Check reviews and seller ratings before making a purchase.
-
eBay and Craigslist: You might find used or aftermarket parts on these platforms at lower prices. However, thoroughly inspect any used parts for wear and tear before purchasing. Counterfeit parts are also a risk here, so proceed with caution.
What are the Most Commonly Replaced Stihl MS 170 Parts?
Certain parts on the Stihl MS 170 are more prone to wear and tear than others. These are the ones you'll likely need to replace most frequently:
-
Chain: The chain is the cutting element and experiences the most wear. Regular sharpening and eventual replacement are necessary.
-
Guide Bar: The guide bar guides the chain and can become damaged or worn over time. A damaged guide bar can lead to chain breakage or poor cutting performance.
-
Air Filter: A clogged air filter restricts airflow to the engine, reducing performance and potentially damaging the engine. Regular cleaning or replacement is essential.
-
Spark Plug: The spark plug ignites the fuel-air mixture. A worn or fouled spark plug can lead to starting difficulties or poor engine performance.
-
Fuel Filter: The fuel filter prevents debris from entering the carburetor. A clogged fuel filter can restrict fuel flow and cause the engine to stall.
How Do I Identify the Parts I Need?
Identifying the specific Stihl MS 170 parts you need can be achieved in several ways:
-
Stihl Parts Diagrams: Stihl provides detailed parts diagrams online and through their authorized dealers. These diagrams show every part of the chainsaw with part numbers. This is the most reliable method for accurate identification.
-
Your Owner's Manual: Your owner's manual should include a parts list or at least a section on maintenance and troubleshooting, which might help you identify needed parts.
-
The Part Itself: If you have the old part, carefully examine it for any markings or numbers. This information can assist in locating the replacement.
How Do I Maintain My Stihl MS 170 to Prolong Part Lifespan?
Proper maintenance significantly extends the life of your Stihl MS 170 and reduces the frequency of part replacements. Key maintenance practices include:
-
Regular Chain Sharpening: Sharpening your chain regularly keeps it cutting efficiently and prevents excessive wear on the guide bar.
-
Guide Bar Lubrication: Always ensure adequate bar lubrication during operation. Insufficient lubrication can cause rapid wear on the bar and chain.
-
Air Filter Cleaning: Regularly clean or replace the air filter to maintain optimal engine performance.
-
Spark Plug Inspection: Periodically inspect and clean or replace the spark plug as needed.
-
Fuel Filter Replacement: Replace the fuel filter at the intervals recommended in your owner's manual.
What are some common problems with the Stihl MS 170?
While the MS 170 is generally reliable, some common issues can necessitate part replacements:
-
Difficult Starting: This can be due to a faulty spark plug, carburetor issues, or a clogged air filter.
-
Poor Cutting Performance: This could indicate a dull or damaged chain, a worn guide bar, or carburetor problems.
-
Engine Running Rough: This is often caused by a faulty spark plug, carburetor problems, or a clogged fuel filter.
By understanding the common replacement parts, where to source them, and how to maintain your Stihl MS 170 chainsaw, you can ensure its longevity and keep it performing at its best. Remember to always consult your owner's manual for detailed information and specific recommendations.
