Husqvarna 450 Rancher Chainsaw question

This might not be the correct forum but I thought I would start here. I have an older Poulan 2375 that was pretty simply to replace bars and chains. There didn't seem to be options for sprocket, bar or chain DLs. I was trying to buy an extra chain and bar for my new 450 but I ran into too many different length sizes and heights for a 20" chain (that came with it). My bar states 80 dl so I believe that I am suppose to buy a chain that has 80 dl. Are the sprocket, bar and chain suppose to match? I never had to deal with this on my older Poulan. Thx!!!!

The sprocket will be specific to the saw, but could have the option of a .325 or 3/8 pitch sprocket. Now bars can get more complicated due to different lengths and different gauges. The chain pitch, gauge, and drive count have to match the bar. So a .325 pitch with .050 gauge( drive link thickness) and 80 drive count chain has to be used with a .325, .050, 80 bar. Now it appears that the 80 drive link count is unique to Husqvarna with 78 being the more common link count for a .325 20" chain So will have to pay attention to buying new bars and chains because the 78 and the 80(most likely Husqvarna dealer only) link count bars and chains can be found for Husqvarna saws.

Chains can come in different gauges. So .043, .050, .058, and .063 are used in different chains for various chainsaws.

.043 is limited to the small 3/8 chains(3/8 LP) as well as some .325
.050 is the most common and used on 3/8 LP, .325 and the big 3/8
.058 is used with .325 and the large 3/8 and was common on Husqvarna and Solo saws but is also most an obsolete size
.063 is used on .325 and large 3/8 exclusive to Stihl saws.

So if I understand you correctly, order a BAR and chain replacement based on the nomenclature stamped on my existing bar, for a perfect fit? My 20" bar lists .325 80 dl and 1.3 mm. I guess the 1.3 mm is the gauge???

1.3 converts to a .050 gauge bar. If you are just replacing the bar and have 80 dl chains you want to continue using, then you need a 80 dl bar. If you are replacing both the bar and chain and don't have extra chains that you want to use then you can purchase the normal 78 dl bar and 78dl chain.

Your bar mount on your chainsaw is the Oregon equivalent of the K095 mount. Which fits Husqvarna, Poulan/Pro, Solo, and Dolmar/Makita.
