ARCHER SPROCKET FITS ECHO CS-590 TIMBERWOLF, CS-600P, CS-620P 3/8 PITCH

...bearing seems right on too... (be nice if the e-clip was included, I always use a fresh one. MHO) and the rim drive should save a lot of wear'n'tear too...

As always right product, price and service. Will do business with again.

Sprocket fit as it should and works fine. Two piece sprockets seem to run smoother to me, and I keep a spare on the truck so a lot less space taken up.

Works great and lets me use a bigger sprocket for more chain speed. Adding 1 tooth lets the saw 'noodle' better. The noodles land behind the saw and not straight down. I can noodle longer w/o having to stop and clear the noodle pile away.
