Essential Engineering Checklist for Stihl 170 Chainsaws
Choosing the right parts for stihl 170 chainsaws requires matching technical dimensions to the MS170 platform while balancing cost against replacement frequency. The following criteria cover the most frequent failure points and upgrade decisions observed across user reports and specification sheets.
Chain Pitch, Gauge, and Drive Link Compatibility
The Stihl MS170 and related 017/018 series use a low-profile 3/8 inch LP pitch chain with .043 inch (1.1 mm) gauge and exactly 55 drive links for standard 16 inch bars. Any deviation in these three measurements causes the chain to bind on the bar, skip teeth on the sprocket, or fail to seat in the drive links. Always verify the part numbers 61PMM355, 61PMMC3-55, or Oregon 90PX055G equivalents before purchase. Multi-packs that list these exact figures reduce the risk of ordering errors compared with generic listings.
Bar Length and Combo Kits
A 16 inch bar remains the factory match for the MS170 powerhead. Combo kits that pair a new bar with a pre-stretched chain eliminate the need for separate tensioning adjustments during initial install. When the original bar shows groove wear or rail peening after 20-30 hours of use, replacing both components together restores straight cuts and reduces chain stretch. Single chains remain suitable for users who already own a serviceable bar and simply need a spare.
Carburetor Fitment and Replacement Standards
Carburetors for the MS170 must match Zama C1Q-S57, C1Q-S57A, or C1Q-S57B castings and the OEM part 1130-120-0603. Aftermarket units that list these exact replacements typically include the necessary gaskets and linkage arms. Improper throttle shaft diameter or missing impulse ports produce lean running conditions and hard starting. Confirm the listing covers both MS170 and MS180 variants when the saw has been previously modified.
Brand Consistency and Material Quality
OEM Stihl Oilomatic chains and Oregon low-kickback replacements offer documented heat treatment and chrome plating that extend cutter life under abrasive conditions. Value multi-packs from secondary brands provide acceptable performance for occasional users provided the pitch and gauge remain exact. For frequent cutting, the material consistency of established brands reduces the frequency of filing and tensioning. Cross-check listings against the Chainsaws category resources for additional platform comparisons.
Pack Quantity and Cost Efficiency
Single chains suit users who file regularly and keep one spare. Two-pack, three-pack, four-pack, and five-pack options lower the per-chain cost and ensure a ready replacement when a chain is damaged mid-job. Calculate the effective price per chain by dividing total cost by quantity. For example, a multi-pack priced near the lower end of entry-level to premium often delivers better long-term value than repeated single purchases at higher unit prices.
Low-Kickback Features and Safety
Low-kickback designs incorporate bumper drive links and reduced cutter angles that limit rotational force if the nose contacts an object. All chains intended for the MS170 consumer class should carry this designation. Pairing a low-kickback chain with a properly fitted bar nose sprocket and chain brake maintains the original safety envelope of the saw.

Common Questions on Stihl 170 Chainsaws Answered
What chain specifications fit Stihl 170 chainsaws?
Stihl MS170 models require a 3/8 inch LP pitch chain with .043 inch gauge and 55 drive links for the standard 16 inch bar. Confirm the listing includes these three numbers or the part codes 61PMM355 / 61PMMC3-55 before ordering to ensure proper sprocket engagement and bar seating. For broader ecosystem context, read through our operational guide on greenworks 40v 18 vs ego cs1800.
How often should I replace the chain on a Stihl MS170?
Replace the chain when cutters can no longer be filed to a sharp edge or when stretch exceeds the available bar adjustment range. Under typical homeowner use this occurs after several seasons; keep a spare multi-pack on hand so cutting can resume immediately after a damaged chain is removed.
Can I use aftermarket carburetors on Stihl 170 chainsaws?
Yes, provided the carburetor lists exact replacements for Zama C1Q-S57, C1Q-S57A, C1Q-S57B or OEM 1130-120-0603. Units matching these castings install with the original linkage and gaskets and restore correct air-fuel mixture without further tuning in most cases.
Is a bar and chain combo better than buying parts separately?
A matched bar and chain combo restores both rail condition and chain geometry at once, which is preferable when the existing bar shows wear. Separate chains remain more economical if the bar rails are still straight and free of peening. Evaluate current bar condition before deciding.
