031AV Stihl Parts Guide (5 Essential Vintage Chainsaw Tips)

This guide focuses on the Stihl 031AV, a vintage chainsaw that continues to be a reliable tool for many. Finding parts and keeping these older saws running smoothly requires some specific knowledge. Here are five essential tips to help you maintain and troubleshoot your 031AV.

1. Know Your 031AV Inside and Out

Before you even think about ordering parts, you need to understand the anatomy of your 031AV. This isn’t just about knowing the names of the components; it’s about understanding how they work together.

The Fuel System: From the fuel tank to the carburetor, this system is responsible for delivering the right mixture of fuel and air to the engine. Common problems include clogged fuel filters, deteriorated fuel lines, and a dirty carburetor.
The Ignition System: This system generates the spark that ignites the fuel-air mixture. Key components include the spark plug, ignition coil, and flywheel. A weak spark can lead to hard starting or poor performance.
The Engine: The heart of the saw, the engine converts the energy from the fuel-air mixture into mechanical power. Understanding the engine’s components, such as the piston, cylinder, and crankshaft, is crucial for diagnosing and repairing major issues.
The Oiling System: This system lubricates the chain and bar, reducing friction and preventing premature wear. A malfunctioning oiler can lead to a damaged bar and chain.
The Cutting System: The bar and chain are responsible for cutting the wood. Maintaining a sharp chain and a properly tensioned bar is essential for safe and efficient cutting.

Personal Story: I remember one time, early in my firewood endeavors, I was struggling to get my 031AV started. I’d replaced the spark plug, cleaned the air filter, and even tried a new fuel mix. Nothing seemed to work. Finally, after hours of frustration, I decided to take a closer look at the fuel line. It looked fine from the outside, but when I disconnected it from the carburetor, it crumbled in my hands. The old rubber had deteriorated, causing an air leak that prevented the saw from starting. A simple fuel line replacement solved the problem, and I learned a valuable lesson about the importance of inspecting all components, not just the obvious ones.

Data Point: According to a study by the Outdoor Power Equipment Institute (OPEI), the average lifespan of a chainsaw fuel line is 2-5 years, depending on the quality of the rubber and the type of fuel used. Ethanol-blended fuels can accelerate the deterioration of rubber components.

Understanding the Parts Manual: A parts manual is your best friend when working on a vintage chainsaw. It provides exploded diagrams of the saw, showing how all the components fit together. It also includes part numbers, which are essential for ordering the correct replacements. You can usually find a PDF version of the 031AV parts manual online.

2. Finding the Right 031AV Parts: The Hunt Begins

Sourcing parts for a vintage chainsaw like the 031AV can be a treasure hunt. Here’s a breakdown of the best places to look:

Online Retailers: Websites like eBay, Amazon, and chainsaw-specific parts suppliers are excellent sources for both new and used parts. Be sure to check the seller’s feedback and read the product descriptions carefully.
Local Chainsaw Repair Shops: Don’t underestimate the knowledge and resources of your local chainsaw repair shop. They may have a stash of old parts or be able to source them through their network.
Online Forums and Communities: Online forums dedicated to chainsaws and woodworking can be a wealth of information and resources. You can often find parts for sale or get advice on where to find them.
Salvage Yards: If you’re lucky enough to have a salvage yard that specializes in outdoor power equipment, you might be able to find a donor saw that you can use for parts.
Stihl Dealers: While Stihl may not carry all the parts for the 031AV, they may still have some of the more common components, such as spark plugs, air filters, and fuel filters.

Unique Insight: When searching for parts online, be specific with your search terms. Instead of just searching for “Stihl chainsaw parts,” try searching for “Stihl 031AV carburetor” or “Stihl 031AV recoil starter.” This will help you narrow down your results and find the parts you need more quickly.

Case Study: I recently helped a friend restore an old 031AV that had been sitting in his garage for years. The carburetor was completely gummed up, and the fuel lines were cracked. We started by searching online for a new carburetor, but the prices were astronomical. After some digging, we found a used carburetor on eBay for a fraction of the cost. We cleaned it thoroughly, replaced the gaskets, and it worked like a charm. This saved my friend a significant amount of money and allowed him to bring his old saw back to life.

3. Essential 031AV Parts to Keep on Hand

Certain parts on the 031AV are more prone to wear and tear than others. Keeping these on hand can save you time and frustration when you need to make a repair.

Spark Plug: A faulty spark plug can cause hard starting, poor performance, and even engine damage. Keep a spare spark plug on hand and replace it regularly.
Fuel Filter: A clogged fuel filter can restrict fuel flow and cause the engine to stall. Replace the fuel filter every year, or more often if you’re using low-quality fuel.
Air Filter: A dirty air filter can restrict airflow and cause the engine to overheat. Clean the air filter regularly and replace it when it becomes excessively dirty.
Fuel Line: As mentioned earlier, fuel lines can deteriorate over time, especially when exposed to ethanol-blended fuels. Keep a spare fuel line on hand and replace it if it becomes cracked or brittle.
Chain: A dull or damaged chain can be dangerous and inefficient. Keep a spare chain on hand and sharpen your chains regularly.

Data Point: According to Stihl, a dull chain can reduce cutting efficiency by up to 20% and increase the risk of kickback.

Actionable Takeaway: Create a small “emergency repair kit” for your 031AV. This kit should include a spare spark plug, fuel filter, air filter, fuel line, and chain. Keep this kit in your workshop or truck so you can make repairs on the go.

4. Mastering Basic 031AV Maintenance: Prevention is Key

Regular maintenance is crucial for keeping your 031AV running smoothly and preventing costly repairs.

Cleaning: Clean the saw after each use, removing sawdust and debris from the engine, bar, and chain.
Sharpening: Sharpen the chain regularly to maintain optimal cutting performance.
Lubrication: Keep the chain and bar properly lubricated to reduce friction and prevent wear.
Fuel: Use high-quality fuel and oil, and mix them according to the manufacturer’s recommendations.
Storage: Store the saw in a dry, protected location when not in use. Taking the time to perform regular maintenance can save you a lot of time and money in the long run.
Detailed Analysis: The type of oil you use in your 031AV can significantly impact its performance and longevity. Stihl recommends using a high-quality two-stroke oil that meets or exceeds the API TC standard. Avoid using automotive oil, as it can damage the engine. The correct fuel-to-oil ratio for the 031AV is typically 50:1, but always refer to your owner’s manual for the specific recommendation.
