I have an opportunity to buy a 330 with and I quote "a twisted off shaft". For $30, comes with 2 bars and 6 chains. What's the history with the cranks on these? Seems like a complete rebuild? Any info is much b appreciated!
They were somewhat known for breaking the crankshaft on the drive side. I don't have the complete history but I'm fairly sure it was more common on earlier models and Homelite addressed the problem at some point and made an improvement. Back in the 80's it was pretty common, nowadays you don't hear as much about it.
And yes, it would require a complete teardown, split the outer case and split the engine case. If you've done one, it's really not that bad. On your first one, there's some learning curve mainly to splitting the outer case and getting it all back together. Once you get to the engine, it's pretty easy. The engine case splits at the crankshaft center line so you pop the crank, rod and piston out into your hands. And all the engine case screws are readily accessed with a nut driver or electric driver of your choice, no endless end-wrenching like on many other models.
The bars and chains alone sound like they could make the deal a good buy, depending on condition. The saw itself would likely make a dandy donor if you find another one that doesn't need as much work. Or if you find another donor or box of parts with a good crank, it's not that tough to put them together.
