Losi XXX-T Gear Grinding
Hi folks,
I bought a used XXX-T and have been running it for a while now. As of recent, I get a grinding noise when I run it. When I hold it up in the air, all is well. But as soon as I put it on the ground, it starts grinding away. I've changed the spur gear (84) and the pinion (17-20) with no luck. Think it is something in the transmission? When I took the tranny apart, the middle gear had a saw like pattern on it (like the teeth were bent forward). I really have no idea because the grinding sounds like it's coming from the spur/pinion combo. I've also moved the pinion closer or farther away from the spur. Any help would be great.
Thanks a lot.
