Common Questions ▼
Q: What does Stihl part number 3623 005 0091 fit?
A: Stihl part 3623 005 0091 (33RSC 91E) fits Stihl chainsaws that use a 3/8" pitch, 0.050" gauge guide bar with 91 drive links, including many MS 251, MS 261, MS 271, and MS 291 configurations. Always confirm your guide bar specifications before ordering.
Q: What is the difference between the Stihl 33RSC and other Stihl RSC chain models?
A: The 33RSC designation identifies the chain's cutter style (Rapid Super Comfort, semi-chisel) and gauge (0.050"/1.3mm). The number following — 91E in this case — refers to the total drive link count of the chain loop. Different RSC chains share the same cutter style but differ in pitch, gauge, or drive link count to fit different bar lengths and chainsaw models.
Q: Is the Stihl 33RSC 91E chain a low-kickback chain?
A: Yes. The Stihl 33RSC 91E (part 3623 005 0091) is engineered with Stihl's Rapid Super Comfort low-kickback geometry, incorporating tie straps and cutter profiles that reduce the risk of kickback during operation, making it a preferred choice for homeowners and occasional-use operators.
Q: How do I know if part 3623 005 0091 is the correct replacement chain for my Stihl MS 271?
A: Verify that your Stihl MS 271's guide bar is rated for a 3/8" pitch, 0.050" gauge chain and requires 91 drive links. This information is typically printed on the guide bar itself. If all three specifications match, the Stihl 33RSC 91E (3623 005 0091) is a direct OEM fit for your saw.
