Overview
Designed as a drop-in aftermarket replacement, this 28” bar and chain combo takes the guesswork out of ordering parts separately. The bar rail and chain pitch are matched at the factory, so everything lines up the first time you mount it. A practical upgrade for homeowners maintaining their own firewood saws.

- Bar length: 28”
- Chain pitch: 3/8”

Compatibility
Engineered to fit Stihl MS660 MS661 MS460 MS461 MS650-3/8” Pitch 91DL saws and other models sharing the same bar-mount pattern. Always double-check your saw’s model number against the full compatibility list before ordering, since mount studs and oiler holes can vary between production years.
Installation notes
Loosen the bar-mount nuts and slide the old assembly off. Before fitting the new bar, clear packed sawdust from the oil passage and around the drive sprocket. Place the new bar onto the studs, route the chain around the bar groove and sprocket, then adjust tension to the point where you can pull the chain around by hand with light resistance. Snug the nuts in a cross pattern.
Common questions
Q: Will this 28 inch bar and chain combo fit my Stihl MS661, and do I need to match anything besides the saw model?
Yes, this combo is made for Stihl MS660, MS661, MS460, MS461, and MS650 saws that use the 3003 mount, a 3/8” pitch setup, and a 91 drive link chain. Before installing, confirm your current bar mount pattern and count the drive links on your old chain, because those specs need to match along with the saw model.
Q: Is the chain on this 28 inch combo semi-chisel, and is that a good choice for cutting dirty or hardwood timber with my MS460?
Yes, this comes with a 3/8” pitch 91DL semi-chisel chain, which is a practical choice for hardwood and for conditions where the wood may not be perfectly clean. Semi-chisel cutters usually hold an edge better than full-chisel in dirty or abrasive conditions, though they may cut a little slower in clean wood.
Q: When installing this 28 inch replacement bar and chain on my Stihl MS660, what tension and maintenance steps should I follow?
After mounting the bar and chain, tension it so the chain sits snug against the bar but can still be pulled around by hand with gloves on. It also helps to verify the oil hole lines up, fill the bar oil reservoir, and recheck chain tension after the first few minutes of cutting since a new chain will usually stretch slightly.
