Overview
This 2-pack of aftermarket 16-inch replacement chains is designed to fit select Homelite chainsaw models. Over time every chain stretches, dulls, and eventually needs replacing. This aftermarket option matches the OEM pitch, gauge, and drive-link count so you can install it directly without modifications. A fresh chain also reduces strain on the bar and sprocket.
Key specifications
- Bar length: 16”
- Quantity: 2-pack
- Type: Semi-chisel (aftermarket replacement)
Compatibility
Engineered to match the specifications of select Homelite chainsaw models, this chain drops in without modification. Before ordering, verify the three critical numbers — pitch, gauge, and drive-link count — against the stamp on your guide bar. A mismatch in any one dimension means the chain won’t fit safely.
Installation notes
Start by removing the battery or disconnecting the power cord. Take off the bar-cover plate and release bar tension. Pull the old chain out of the groove and off the sprocket. Seat the replacement chain into the bar groove — cutters must face forward on the top of the bar. Engage the chain on the drive sprocket, reinstall the cover, and adjust tension so the chain lifts about a dime’s width off the bar and springs back. Hand-rotate the chain to check for binding before powering on.
Common questions
Q: Will this 2-pack S56 16” chain fit my Homelite UT43123 electric chainsaw, and does it also work on the ZR43120?
Yes. This S56 replacement chain is made for the Homelite UT43123 and ZR43120 16-inch 12 Amp electric chainsaw, so it matches the required 16-inch bar setup for those models. As long as your saw is using the stock 16-inch bar, this chain should fit properly.
Q: How do I know if the chain tension is correct after installing this S56 chain on my UT43123?
After installation, the chain should sit snugly against the bar but still pull around by hand with gloves on. If you lift the chain at the middle of the bar, the drive links should start to come out of the bar groove slightly, but the chain should not hang loose underneath the bar.
Q: Do these 16” S56 replacement chains come sharpened, and what maintenance should I do to make them last longer on my Homelite electric saw?
Yes, replacement chains like this typically come pre-sharpened and ready to install. To extend chain life, keep bar oil filled, clean sawdust from the bar groove and sprocket area, and check tension frequently since a new chain can stretch a bit during the first few uses.
