User question

where to buy Stihl MS170 chainsaw parts

Artificial Intelligence ResponseLABEL_AI_GENERATED

Direct answer to the question

For a STIHL MS 170 / MS170 chainsaw, the best place to buy parts depends on whether you want genuine STIHL OEM parts or lower-cost aftermarket parts:

Need Best place to buy
Genuine STIHL parts Local authorized STIHL dealer
Warranty-related repair parts Authorized STIHL servicing dealer
Aftermarket carburetors, filters, fuel lines, recoil parts, tune-up kits Hipa, HL Supply / HLS Pro Parts, Sawzilla, Amazon, eBay
Bar, chain, sprocket, files, maintenance parts STIHL dealer, Oregon dealers, hardware stores, online marketplaces
Engine internals or safety-critical parts Prefer OEM STIHL from a dealer

STIHL’s own dealer locator specifically lists authorized dealers as sources for original spare parts and accessories, and STIHL warns against counterfeit or unauthorized online sellers posing as official retailers. (stihlusa.com)


Detailed problem analysis

1. Best source for genuine STIHL MS170 parts

If you want real STIHL OEM parts, use an authorized STIHL dealer. This is especially important for:

  • Carburetor assemblies
  • Ignition modules
  • Clutch components
  • Chain brake parts
  • Oil pump parts
  • Crank seals
  • Piston/cylinder assemblies
  • Safety-related covers and brake components

In the U.S., STIHL generally routes genuine replacement parts through its authorized dealer network rather than treating parts like a normal open online marketplace item. STIHL also states that suspiciously discounted online products may be counterfeit, poorly made, unsafe, and not covered by STIHL warranty. (stihlusa.com)

Practical tip:
When you go to the dealer, bring:

  • The saw: MS 170
  • The serial number
  • The failed part, if available
  • Bar length and chain information, if buying cutting components

That helps the parts counter identify the exact revision.


2. Good online aftermarket sources

If your saw is out of warranty and you are comfortable using non-OEM parts, aftermarket parts are widely available for the MS170, because it shares many parts with the 017, 018, and MS180 family.

Common online sources include:

Supplier Typical parts available Notes
HL Supply / HLS Pro Parts OEM and aftermarket parts for STIHL 017, 018, MS170, MS180 Good chainsaw-specific supplier; lists MS170/MS180 category parts. (hlsproparts.com)
Hipa Store Carburetors, air filters, fuel lines, spark plugs, chains, tune-up kits Useful for inexpensive maintenance kits; Hipa lists STIHL-compatible chainsaw repair parts. (hipastore.com)
Sawzilla Parts Carb kits, oil lines, worm gears, filters, recoil parts, aftermarket MS170 parts Common aftermarket chainsaw parts source.
Amazon / eBay Tune-up kits, carburetors, chains, pull starters, covers, filters Convenient, but verify seller quality and part number carefully.
Local small-engine repair shops OEM or aftermarket parts Often better than guessing online, especially for fuel and ignition problems.

Practical buying guidance

Use OEM parts for these

I would strongly prefer genuine STIHL parts for:

  • Chain brake parts
  • Clutch drum and clutch hardware
  • Ignition module
  • Flywheel
  • Crankshaft seals
  • Bearings
  • Piston/cylinder assembly, if you want long service life
  • Oil pump components
  • Any part involved in safety or high-speed rotating loads

Reason: the MS170 is a small high-speed two-stroke machine. Poor crank seals, bad carburetor calibration, or inaccurate ignition timing can cause lean running, overheating, seizure, or unsafe operation.

Aftermarket is usually acceptable for these

Aftermarket parts are often reasonable for:

  • Air filter
  • Fuel filter
  • Fuel line
  • Spark plug
  • Primer bulb, if equipped
  • Starter rope
  • Recoil handle
  • Bar nuts
  • Chain
  • Guide bar
  • Carburetor for a low-cost repair on an older saw

For a homeowner-grade MS170, a complete aftermarket tune-up kit can sometimes be cheaper than a single OEM carburetor repair.


Important compatibility notes

The MS170 is part of STIHL’s 1130 series family, related to the 017, 018, and MS180. Many parts interchange, but not all. Before ordering, verify:

  • Exact model: MS 170, MS 170 C, or regional variant
  • Serial number
  • Carburetor type
  • Bar mount pattern
  • Chain pitch, gauge, and drive-link count
  • Whether your saw uses older or newer fuel-system components

For the chain and bar, do not rely only on “fits MS170.” Check:

\[ \text{Pitch} \quad + \quad \text{gauge} \quad + \quad \text{drive link count} \]

Common MS170 setups use low-profile 3/8 in chain, but the exact gauge and drive-link count depend on the bar.


Where I would buy, in order

If you want the safest answer

  1. Use the STIHL Dealer Locator.
  2. Call the nearest authorized dealer.
  3. Give them your MS170 serial number.
  4. Ask for the exact OEM part number.

This is the best route for genuine parts and avoids counterfeit components. (stihlusa.com)

If you want cheaper repair parts

Look at:

  • HLS Pro Parts / HL Supply
  • Hipa Store
  • Sawzilla Parts
  • Amazon or eBay, but only if the seller has good reviews and clear part-number compatibility

HLS Pro Parts specifically lists parts for STIHL 017, 018, MS170, and MS180 saws. (hlsproparts.com)


Brief summary

For genuine STIHL MS170 parts, buy from an authorized STIHL dealer. For cheaper non-OEM parts, use chainsaw-specific suppliers such as HL Supply / HLS Pro Parts, Hipa, Sawzilla, Amazon, or eBay. Use OEM for engine, ignition, clutch, and safety-critical parts; aftermarket is usually acceptable for filters, lines, starter parts, chains, and basic tune-up items.
