Good deal.
I look forward to it mowing again as I am sure your neighbors feel the same way.

Last night I got the motor fully reassembled. It took a good chunk of time. Unfortunately, the acid got into the brushes and brush holders. Thus the brushes were seized in placed by corrosion. I tried pushing them out, hammering them out, lubricating them. Then I started digging and found the tiniest cutest little gear puller. It did a wonderful job of being able to essentially press them out.





To clean it up, I have some Deka battery acid cleaner stuff. It neutralizes the acid and then you can clean it up easier. It sprays on yellow and turns red if it hits acid. Super handy stuff for this job. I sprayed down the brush holder really well, let it sit, then rinsed it off with water. I did this again to make sure there was no more red. I then had to go in ever brush holder with a fine file and clean it all up so the new brushes would go in smooth.

After that, it was standard assembly. I got everything back together and hooked up the motor to an old computer power supply to run on 5 volts for the next day or so to seat the brushes. Here is the simple setup.

That acid sure caused a bunch of work/time spent on it.

That is for sure! I will be figuring out some sort of diverter / guard plate that protects the motor from EVER getting acid in it again.

If I may humbly suggest maybe the time to start thinking of a lithium battery swap. Either a CALB cell or maybe a Chevy volt take out. The lithium batteries are amazing. Very light and high energy density, you may be able to cut your grass twice before needing a charge. NO acid problems here and they will last you a LONG time (with a proper charge)
