Exclamation losi 8ight t 1.0

HELP HELP HELP HELP I have a losi 8ight t 1.0 that I have converted to a Electric my issue is I can not keep the center diff from burning up I have a castle creations mamba max esc and 2650 motor I run a 4 cell lipo in it the diff gear is a 45 t I tried a 48 t but it would hit the chassis and wasn't turning so had to put the 45 t on there but it wont hold up I have tuned some things down haven't changed any diff gears out yet to see if that helped any I hate to waste another diff if its not fixed . I know the 8ight t 2.0 has a 50t center diff gear in them but I figured if the 48t hit the chassis then the 50 t would to iam also thinking that the gear on the motor is a 16 t or 17 t not so sure on that any help will do thanks in advance please help me

Have you shimmed the diff occasionally to maintain proper mesh? Checked the housing for wear or damage in the bearing support area?

no I haven't Dave I am not to good at these things I can take a part off and replace it but other than that I am learning as I go. but it isn't getting hot I just tried it again and under its own weight it pulls and grinds like crazy and bud only at a 1/3 of power but if you pick it up the back wheels pull at full power and the front wheels don't pull at all the center diff turns for the back and front but the front wheels wont turn at all so I about to give up on and go back to my buggy

Dave I did check the center diff before I put it on it everything did fill tight and bearings felt good so I may take it off in a few and take the diff a part and see whats up with it
