MS 500i
MS 500i OEM Parts
Find genuine STIHL OEM replacement parts for an MS 500i chainsaw for maintenance, troubleshooting, or repair. Begin with the exact model designation, serial number, and OEM part number if known. Compare those details with the product title and application information before ordering.
Begin With the Failed System
Start with the symptom and the assembly that needs attention. Inspect the complete system, identify the failed part, and use an illustrated diagram where needed. This helps build a complete order instead of replacing only the most visible item.
MS 500i Parts by Service Area
Depending on current inventory, this collection may include genuine STIHL MS 500i OEM components for the following repair and maintenance areas:
- cylinder, piston, crankshaft, crankcase, bearings, gaskets, and sealing parts;
- air intake, filter, fuel tank, fuel line, fuel-system, and related components;
- starter housing, recoil components, electrical parts, wiring, switch, and controls;
- clutch, sprocket, chain tensioner, oil pump, worm gear, and lubrication parts;
- chain brake, hand guard, throttle controls, handles, and anti-vibration mounts;
- covers, caps, springs, clips, screws, retainers, and other service hardware.
Use the category that matches the repair area to narrow the catalog. For example, an oiling problem may involve the pickup, drive, oil pump, delivery path, or a seal. A starter issue can involve the rope, pulley, spring, pawl, housing, handle, or hardware. Identifying related components before you order can save time and avoid an incomplete repair.
Confirm the Listing Before Purchase
Read the full product page for every item in your order. Confirm the OEM number, MS 500i application, title, description, quantity, and included parts. Product photographs are useful for recognizing an item, but they should not be treated as a fitment guarantee. A photo may not show every angle, may include items sold separately, or may represent a product family rather than the exact component offered.
When an OEM part number is replaced by another reference, check that the current number is specified for your MS 500i serial range. If the listing does not clearly state the application, verify it before checkout. This is especially important for components associated with the fuel system, wiring, controls, engine, or safety functions. Ordering the correct item is more efficient than fitting a part and discovering a compatibility problem afterward.
Maintain the Drive and Lubrication Path
Regular attention to the cutting attachment helps protect the saw and the parts around it. Inspect the guide bar, chain, drive sprocket, clutch cover, chain catcher, and oil outlet. Keep the bar groove free of packed debris, maintain correct chain tension, and sharpen the chain as directed by STIHL. If oil delivery is reduced or absent, stop using the chainsaw until the cause has been found. Running with inadequate lubrication can damage the guide bar, chain, sprocket, and related components.
Clean the clutch-cover area and inspect for debris, loose fasteners, a worn sprocket, or damaged guards. Identify the cause before replacing a part; oil-delivery and chain-drive problems can involve more than one component.
Install Parts With Safety in Mind
Work on a clean surface, keep removed hardware organized, and follow the applicable STIHL service procedure. Allow the saw to cool before beginning work and use appropriate protective equipment. Do not force electrical connectors, threaded components, plastic covers, fuel lines, or control pieces. If you are not comfortable with a repair involving engine internals, fuel delivery, electrical systems, or safety controls, ask a qualified small-engine technician to inspect the machine.
Test Safety Features
Before returning the MS 500i to service, inspect the chain brake, front hand guard, throttle trigger, throttle interlock, stop control, chain catcher, handle mounts, and fasteners. Replace any damaged, missing, or non-functioning safety part with the correct application-specific component. Complete the recommended checks before operating the chainsaw. Do not use equipment with a safety feature that is loose, binding, or not functioning normally.
Get Fitment Help
When you need help locating a product, provide the model, serial number, OEM part number if known, and a description or photo of the item’s location. These details let us narrow the catalog search more effectively. Final compatibility should always be verified with the product listing and your machine’s applicable parts information.
