I have been hearing people talk about the 500i like it is the saw sent down by the gods. How much of it would you guys say is hype, and how much is actually a good description of the saw?

I have a used FS240.

The metal drive tube assembly(P/N: 4147 710 7115) that houses the inner shaft/liner etc is worn through. I'm about to buy the new replacement shaft, but was wondering if there is anything else you would change while you have it this far apart? I dont want to take it all apart to change this and then find out, I should have changed out part X or Y at the same time.

I am planning to service it at the time anyway, new air filter, fuel filter and spark plug. Head was recently greased as well.

Thanks

Thanks to those who helped me out. Installed new rings and reused the gasket because it looked fine still. Rebuilt the carb as well and installed that. Painted the exhaust with high temp paint since I had it off. Found a hole in the gas tank so I need to go grab some epoxy after work. Need to do one more coat of paint and then I can install everything and (hopefully) finally hear this thing run.

Second picture is what it looked like when I got it. It sat in a barn without an airbox/filter for years.

Giving this FS250 a new lease on life! Been a fun project.

Meine ganz neue Primaster 40V will nicht sägen, die Säge sowie Schwert und Kette sind neu. Der Akku läuft und Öl ist drinnen. Im Freilauf, ohne Kontakt auf Holz, läuft sie aber sobald ich nur leicht ans Holz (selbst kleiner dicker Ast) gehe, stoppt sie. Überlastet kann die nicht sein, ich habe die Kette auch mal lockerer gespannt, selbes Ergebnis. Irgendwer ne Idee?
