2PC 20 Inch Chainsaw Chain for Poulan Pro PP5020AV / PR5020

20-inch replacement chain fitment for Poulan Pro PP5020AV / PR5020

This 2-pack 20-inch replacement chain is intended for Poulan chain saw models PP5020AV, PR5020, and 5020 as listed in the original fitment information. It is a full chisel chain, and the package includes 2 pieces, making it a practical option if you want one chain ready to use and one spare on hand.

Will this chain fit your saw?

The easiest starting point is the bar length: this listing is for a 20-inch bar. If your saw is a Poulan PP5020AV, PR5020, or 5020 and it is set up with a 20-inch bar, this chain may be the correct replacement.

To confirm fitment, match all of the following chain specs from your current chain or guide bar markings:

• Bar length: 20 inch
• Pitch: match the chain pitch marked on the bar or chain packaging
• Gauge: match the groove width required by your bar
• Drive-link count: match the exact number of drive links on your current chain

A chain can be the right length overall and still not fit properly if the pitch, gauge, or drive-link count is different. That is why checking all four specs matters before ordering or installing.

Compatible model numbers and reference part numbers provided for this listing are:

• Poulan PP5020AV
• Poulan PR5020
• Poulan 5020

Replaces part numbers:

• 577180501
• 72LPX070G
• D70
• E70

If your old chain, packaging, manual, or bar references one of those part numbers, that is a strong fitment clue for this product.

Replacing the chain

Before working on the saw, make sure the engine is off, the saw is cool, and the spark plug is disconnected if you want an extra margin of safety. Wear gloves when handling the old or new chain.

1. Loosen the side cover and remove the bar/chain cover.
2. Back off the chain tension so the old chain can be lifted off the guide bar and drive sprocket.
3. Clean sawdust and oil buildup from around the bar groove, clutch cover area, and sprocket before installing the new chain.
4. Place the new chain around the drive sprocket and along the guide bar, making sure the cutter direction is correct.
5. Reinstall the side cover, then adjust chain tension so the chain sits snugly on the bar but can still be pulled around by hand with a gloved hand.
6. Tighten the bar nuts securely and recheck tension after the first few cuts, since a new chain can stretch slightly during break-in.

If the chain will not seat correctly in the bar groove or on the sprocket, stop and recheck the saw’s pitch, gauge, and drive-link count.

Keeping it sharp

A full chisel chain cuts fast, but it also benefits from consistent maintenance.

• Touch up the cutters regularly instead of waiting until the chain becomes very dull. A few light sharpenings are easier than one heavy regrind.
• Keep the chain properly tensioned and make sure bar oil is flowing. Poor lubrication increases heat, wear, and dulling.
• Avoid cutting into dirt, sand, or anything on the ground. Even a sharp new chain can lose its edge quickly from abrasive debris.

Also inspect the bar occasionally for burrs, uneven rail wear, or a clogged oil hole, since bar condition affects chain life and cut quality.

FAQ

Does this listing include one chain or two?
It includes 2 pieces: two 20-inch full chisel chains.

Will it fit any Poulan saw with a 20-inch bar?
Not automatically. A 20-inch bar is only one part of fitment. You also need the correct pitch, gauge, and drive-link count, and this listing specifically references PP5020AV, PR5020, and 5020, along with part numbers 577180501, 72LPX070G, D70, and E70.

What does full chisel mean?
Full chisel refers to the cutter shape. It is designed for efficient cutting performance, especially in cleaner wood, but it generally needs to be kept sharp and out of dirt to perform its best.
