Dolmar PS-510 sprocket issue

[Tyler laShomb]

Hi All,
I have a small issue that I am trying to make the best out of....i have a Dolmar ps510, 18" and i love it...i bought a box of chains (8 to be exact) that are all 72Dl...i went out and bought a new bar to accomadate the new chains (my old ones were 64DL)..butr now, when i went to use them, i noticed the spur sprocket is not the right size...so...are the sprockets interchangable? can i just order a dolmar 72dl compatible sprocket and change it?

The 510 is listed as using 3/8" pitch chain or .325" pitch chain. The spur sprocket pitch has to match the bar pitch( sprocket nose) and the chain pitch. The gauge of the chain has to match the bar gauge.
