This is what happens when you go a bit too deeply into cleaning and servicing your RC car. I got this bandit about a year ago. It has been bashed hard without many failures. On August 31st that streak ended the motor started smoking then just plain gave up. Within minutes I ordered a brushless replacement it and eagerly waited for it to arrive.
When it arrived a few weeks later. I got to looking at the bandit. I found that it was thrashed. bent and leaking shocks worn bearings wornout driveshafts and it was filthy. Now there are more problems but I am only going to fix the major ones.
The first thing I’m going attempt to fix is the differential (not really broken but going to try and make it better). it has a fully open differential. Causing it to spin only one wheel get stuck way more often than I would like.
To remedy this problem I cleaned out the differential then filled it with a mixture of seatpost grease (it has glass particles in it) and regular grease. This will hopefully add friction and act as a limited slip differential. Failure is always possible time will tell if this will become a problem.
I also repaired the shocks and slipper clutch. First I straightened the bent shaft of the shock. Then proceeded to clean and refill them with a thin grease. The slipper clutch was getting a bit polished and grooved. This was not causing a problem at the moment but I figured it would in the future. I took the clutch and sanded the maiting surfaces using 1000 grit on a peice of glass to remove the polish and any groves.
It is now time for reassembly. Expect an udate in a few days when I get it back together. That’s all for now.
