Full parts list — 274 parts from the manufacturer's IPL

The complete IPL-3120XP_2018-06 parts list, parsed straight from Husqvarna's own document across all 14 assembly groups — searchable, and filtered to your serial number. Use it in preference to the hand-entered table below, which predates it.

Serial filtering matters on this saw: the muffler group changed at week 50 of 2011 and the ignition group at 2017, so 14 parts are serial-dependent — 7 fit a 2001 build and 7 do not.

Search eBay NOS (~$350-$500) Meteor Kit eBay (~$195)
Amazon Generic/Holzfforma (~$85-$130)
Buy Meteor if OEM is too expensive. Avoid $85 generics for heavy milling.
Carburettor (Walbro WG 7A, EPA)
503 28 12-16 · WG10 variant is 503 28 20-01
Search eBay OEM (~$150-$200) Amazon Aftermarket (~$25-$40) The IPL rebuild kit is 503 59 74-02 (Walbro K12-WG). K10-WG is a different kit and is not listed for this saw.
Ignition Coil
503 90 17-01
Search eBay OEM (~$120) Amazon Aftermarket (~$25) OEM preferred for reliability. Amazon clones are hit-or-miss.
Case Splitter Tool
502 51 61-01
Search eBay OEM (~$100+) Amazon Generic (~$45)
eBay Generic (~$35)
Generic Amazon splitter works perfectly fine. Don't waste money on OEM.
Flywheel Puller
502 51 49-02
Search eBay (~$30) Amazon Generic (~$15) Ensure thread pitch matches. Amazon generics are completely viable.
Carburettor rebuild kit

Search eBay (~$20) Amazon Clone (~$10) Always buy OEM Walbro kits. Clone diaphragms harden quickly.

Full BOM with buy links

How to read this table. Status chips describe your own shelf, not live vendor inventory — nothing here queries a supplier. A link tagged CONFIRMED resolves to a specific product page that was opened and priced; UNVERIFIED means the link goes to a vendor home page and the price has not been re-checked. Part numbers are cross-checked against IPL-3120XP_2018-06; any number that does not appear in it is called out inline.
