Overview

Bundled as 2 chains, this chain is a direct replacement for Remington RM4618 RM4620 models. A worn chain strains the motor and increases kickback risk, so timely replacement keeps your saw running safely and efficiently.

Key specifications

  • Bar length: 20”
  • Quantity: 2 chains per pack

Compatibility

This chain is designed to fit Remington RM4618 RM4620. Double-check your model number against the listing to ensure a correct match before installation.

Installation notes

Begin by shutting off the saw and disconnecting the power source. Loosen the bar-mounting fasteners and remove the side cover to access the chain. Slide the worn chain off, seat the replacement around the sprocket and into the bar groove with cutters pointing in the direction of rotation. Tighten the tensioning screw until there is slight play but no droop, then secure the cover.

Common questions

Q: Will this 2-pack 20 inch chainsaw chain fit both the Remington RM4618 and RM4620, or is it only for one model?

Yes, this chain set is made for the Remington RM4618 and RM4620 with a 20-inch bar. If your saw still has the stock 20-inch setup, these replacement chains should fit properly, but it’s always smart to confirm your current chain specs before installing.

Q: Do I need to do anything special when installing one of these 20 inch chains on my RM4620?

Make sure the cutter teeth are facing forward on the top side of the bar before you tension the chain. After installation, adjust the chain so it sits snug against the bar but can still be pulled around by hand, then recheck tension again after the first few minutes of cutting.

Q: How often should I sharpen or replace these chains on a Remington RM4618?

That depends on what you’re cutting and whether the chain contacts dirt or debris, but you should sharpen it anytime it starts pulling to one side or making fine sawdust instead of chips. Replace the chain when the cutters are too worn to sharpen effectively or if you notice damaged drive links, cracked cutters, or repeated stretching.

Not sure which chain you need? See our guide: How to count drive links or Chain pitch, gauge & drive links explained.

Before you buy — how to verify fitment

  1. Find the bar stamp. Look on the side of your current guide bar for the pitch, gauge, and drive-link count.
  2. Match all three numbers. Pitch (3/8), gauge (.050"), and drive links (72DL) must all match.
  3. Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 20".
  4. Confirm your saw model against the compatibility list above. If your model isn't listed, the chain may still fit if pitch/gauge/DL match.

Frequently asked questions

How do I know this chain fits my saw?

Match three numbers: pitch, gauge, and drive-link count. All three must match the stamp on your current bar. If even one is off, the chain won't fit safely.

How do I measure pitch and gauge?

Pitch is the distance between any three consecutive rivets, divided by two. Gauge is the thickness of the drive links — measure with a caliper or check the bar stamp. Our guide covers both in detail.

How long does a replacement chain last?

With proper tension and occasional sharpening, an aftermarket chain lasts 3–5 cords of firewood or about 5 hours of active cutting — roughly the same as OEM.

Can I sharpen this chain or is it single-use?

Absolutely sharpen it. A quality replacement chain can be sharpened 3–5 times before the cutters are too short. Keep a round file matched to the cutter diameter.
