Heart Transplant #1

So as it turns out, even benevolent bee saviors can have health issues. A few weeks ago, Beezus suddenly stopped running. What to do?!

Our first thought was that maybe his poor little batteries were tired. So we let him charge up for a while. No dice.

Next thought was an issue with some of the original wiring as some of it was fairly corroded. After a lot of fiddling around with the multimeter, we decided that wasn’t it either. Which left one last thing…

The motor. We set to work taking it apart, and determined that the brushes had burnt out and broke, and that the commutator was past being salvageable.

TIME FOR A HEART TRANSPLANT!

Fortunately the space where Beezus lives (NIMBY) can be a great place to find old parts, and SuperDave happened to have an old motor from another utility vehicle lying around. We just had to detach it from the axle. This actually ended up being more of an adventure than we had originally anticipated, but after a lot of tinkering and a lot of motor oil getting on basically everything, we managed to make it happen. Ta-Da!

Then came the process of putting the new(er) motor in Beezus. The replacement was slightly bigger, so making it fit was a bit of a challenge. Then came the process of trying to fit the chain back on. We had hoped to do this without taking everything apart, but no such luck. So off came the brake drum and the casing around the chain. Lots more tinkering. Lots more oil. Lots more fun tools.

Eventually, we got the motor in and connected! Then it was time to actually try to run the bee again. SO I pushed down on the gas pedal and… nothing. Wires were connected wrong. Oops! Tried again. AND IT WORKED! Sort of? We managed to get the motor running and wheels turning, but we ran into a slight issue. The new(er) motor had a bad bearing. Siiiiiigh. Well at least we’ll be ready for the next one!
