df-03 rear diff prob :(

[mx0range]

my buggy is fwd! power isnt being transfered to the rear wheels. took it apart and tried to tighten it as much as possible, and its had no effect. i can literally poke either rear wheel when at full speed and they'll both stop with no resistance

new balls, reverse the plates and rebuild it ?


I built the latest DF03 with Kanzen ceramic balls - still it needed to be quite tight to not slip. I put that down to the fairly small diameter so there's less leverage from the balls on the plates??

Do you have a slipper? a slipper set properly should protect the diff - the more the diff slips the worse it will get and more it will slip.

i do have a slipper, yes. should the rear wheels spin in opposite directions when you manually turn 1 of them? the front does, rear doesnt.. im sure it should

[jimmy]

if you hold the spur / centre shaft then yes it should. without holding the drivetrain still then no - it might not! depends how loose the diff / motor and rest of the drivetrain are.

if they are the stock rear diff parts, the plastic holders have commited suicide or just been devoured by a spnning diff ring, so you can tighten it all the way down with no joy.

not plastic, they never went in. i got some 3racing metal ones
