Next installment - Motor cleaning I'm done with warships for a bit so I dusted the Cromwell off to finish the overhaul. Today we open the EV Warrior motors and see what we've got after eight years of battling.
Motor pulled from a the tranny. <https://lh5.googleusercontent.com/-KTnFdgEf26g/U75680VPZ5I/AAAAAAAAAbI/tRv0zintlt4/s1600/ADsc00332.jpg> The back plate is removed. I had bought a lot of used EV Warrior's off eBay back in the day and about half of them had warn back sleeve bearings. I was hoping I wouldn't see the same with these and luckily I did not. Back bearings look good. The front bearings are sealed ball bearing and their OK also. <https://lh3.googleusercontent.com/-sWibTUeSqd0/U757PeJfIjI/AAAAAAAAAbQ/ztiTtVWOINs/s1600/ADsc00335.jpg> Pulling the brush plate off. Note that a socket is used to keep the brushes in place. Also note the three noise caps that were installed in the motors initial modification for R/C combat. <https://lh4.googleusercontent.com/-7XRBhNoKbT8/U758DsxjvBI/AAAAAAAAAbY/w1oYePoUR7Q/s1600/ADsc00336.jpg> Note the clipped off section of brass plate. There used to be tabs here that grounded the motor case to the ground wire. This had to be removed so the motor could be reversed safely. FYI, most automotive application electric motors like the EVW are case grounded. <https://lh3.googleusercontent.com/-vPO_-O3SHuk/U7581A4EzNI/AAAAAAAAAbg/Rp9CM_j5EJ4/s1600/ADsc00334.jpg> Not to much dirt. Mostly carbon dust from the brushes. This was all cleaned out. <https://lh4.googleusercontent.com/-_kfClHWnVV8/U759fByF8-I/AAAAAAAAAbo/f4eSBZnPUwc/s1600/ADsc00337.jpg> Brush plate after a bit of dusting off. Plenty of life left in those brushes. <https://lh3.googleusercontent.com/-qbwF0yY30hU/U7590VeP_CI/AAAAAAAAAbw/Q3XoUHIX5jw/s1600/ADsc00338.jpg> After cleaning up, the back plate gets a dap of grease on the bearing before reassembly. <https://lh6.googleusercontent.com/-_s1aKaqGdFM/U75-QqRJ0cI/AAAAAAAAAb4/fXPXXy0Mruw/s1600/ADsc00339.jpg> I noticed some rubbing wear on the caps so I'm adding a layer of friction tape to help protect them. <https://lh4.googleusercontent.com/-Ftr8RgKcp2k/U75-dCqt2JI/AAAAAAAAAcA/J9KCfICpK5Q/s1600/ADsc00342.jpg> A detail of how the brush to case caps are attached to the case. The case-side leads are wedged between the back-plate and case. <https://lh5.googleusercontent.com/-goadeABHaGI/U75_ew9fwXI/AAAAAAAAAcQ/kLMX7_67BKc/s1600/ADsc00341.jpg> Back in the tank and good for another eight years. <https://lh5.googleusercontent.com/-NJtlM9zP7wg/U75-1khsPOI/AAAAAAAAAcI/RLI0phMMZzg/s1600/ADsc00348.jpg> -- -- You are currently subscribed to the "R/C Tank Combat" group.
