Yeah, I reckon I could easily do it in two, especially if I had a hoist.
Yep, another motor in the shed. That's the other cool thing about K motors, I got it and the box for $100, which may have even been expensive? :)
I'm going to give the motor an inspection and put it in if it's OK. I'm debating making a leak down tester to check condition. Even though it's easy swapping, I have trouble finding spare time, so I don't want to have to find and swap another if I can avoid it.
