The Stihl MS 170 is a popular lightweight chainsaw, ideal for homeowners and occasional users. However, like any power tool, it requires regular maintenance and occasional part replacements. Understanding your MS 170's components and where to source replacement parts is crucial for keeping it running smoothly. This guide will delve into the common parts you might need, where to find them, and some troubleshooting tips.
What are the most common Stihl MS 170 parts that need replacing?
This is a great question, and it really depends on usage. However, some parts are more prone to wear and tear than others. These include:
- Chain: Chains are consumables and will need replacing regularly, depending on use. Look for signs of dullness, stretching, or damage. A dull chain reduces cutting efficiency and increases the risk of kickback.
- Guide Bar: The guide bar guides the chain and can become damaged through contact with rocks, nails, or other obstructions. Check for bending, scoring, or excessive wear.
- Air Filter: A clogged air filter restricts airflow to the engine, reducing performance and potentially causing damage. Regular cleaning or replacement is essential.
- Spark Plug: The spark plug ignites the fuel-air mixture. A faulty spark plug can lead to difficult starting or poor engine performance. Regular inspection and replacement are recommended.
- Fuel Filter: A clogged fuel filter restricts fuel flow to the engine, hindering performance. Inspect and replace as needed.
Where can I find Stihl MS 170 parts?
Finding replacement parts for your Stihl MS 170 is relatively straightforward. Your best options are:
- Authorized Stihl Dealers: These are your primary source for genuine Stihl parts. They ensure the quality and compatibility of the parts, providing peace of mind. They can also offer advice and assistance with installation if needed.
- Online Retailers: Many reputable online retailers sell Stihl parts, often at competitive prices. However, always verify the seller's authenticity and ensure you're purchasing genuine Stihl parts to avoid compatibility issues and potential safety risks. Beware of counterfeit parts!
- eBay and similar marketplaces: You might find used or aftermarket parts here, but proceed with caution. Verify the seller's reputation and ensure the parts are compatible with your specific MS 170 model.
How do I identify the part number for my Stihl MS 170?
Correctly identifying the part number is critical when ordering replacements. You can usually find this information in a few ways:
- Your Owner's Manual: The manual should contain a parts diagram with corresponding part numbers.
- Stihl's Website: Stihl's website provides online parts diagrams for many of their models. You can search using your chainsaw's serial number or model number.
- The Part Itself: Some parts will have the part number stamped or printed directly on them.
How often should I replace the chain and bar on my Stihl MS 170?
The lifespan of your chain and bar depends heavily on usage and maintenance. As a general guideline:
- Chain: Inspect your chain after every use for signs of wear or damage. Regular sharpening is crucial, but eventually, you'll need a replacement. Expect to replace the chain several times per year with regular use.
- Guide Bar: The guide bar is more durable, but it will eventually wear out. Check for damage or excessive wear regularly. Replacement might be needed less frequently than the chain, potentially every few years depending on use.
What are the signs that I need to replace parts on my Stihl MS 170?
Several signs indicate that your MS 170 requires part replacement:
- Difficult Starting: This can be due to a faulty spark plug, clogged air filter, or fuel issues.
- Poor Performance: Loss of power, stalling, or erratic running could indicate several problems, including a clogged air filter, fuel filter, or worn chain.
- Excessive Vibration: Excessive vibration can indicate problems with the chain, bar, or other components.
- Unusual Noises: Any unusual noises, such as grinding or clicking, should be investigated immediately.
By understanding common replacement parts, where to source them, and recognizing the signs of wear and tear, you can keep your Stihl MS 170 running efficiently and safely for years to come.
