Kyosho Ball Diff. Rebuilding AWD MA-010

First time doing something like this. Please bare with me .

I brought this AWD with me to the Philippines in March and ran it there (RCP track of course). It's the same car with the same diffs that I used for RCX event. After months... I finally found time to rebuild my diffs .

I use Kyosho ball diffs with PN ceramic diff balls, open steel ball bearings and green slime for grease.

Tools/Items you'll need:
-tweezer
-Q-tips/cotton buds/cotton swabs (whatever you call it)
-1500 grit sand paper
-ball diff grease (I use green slime made my Team Associated)
-low pressure air can
-all purpose electric cleaner
-used tire
-medicine container or similar (you can also use can covers like wd-40 covers etc...)

Tools:

Kyosho diff:

Take the diff apart and clean it with dry paper towel:

Wet sand the plates with 1500 grit. Place the used tires on the tip of your finger and use this to hold the plates down on the sand paper and do a circular motion:

You want the plates to look like the one on the left.

Remove the gear diff bearing:

Place the bearing inside the small container. Spray electric cleaner onto the bearing and also roll the bearing using the hex driver. You can also do this with the outside ball diff bearings:

This is how mine looked after months of not cleaning the bearings :

Spray a small amount of cleaner on the Q-tip and use this to clean the inside bearing. Sometimes there's build up in there.

When done, use low pressure air spray to blow the dirts out of the bearing. (only for open bearings. I use open and kept mine dry)

Place the diff balls on a clean paper towel and roll it with your finger till it's clean:

Apply small amount of grease on you palm and roll the diff balls on it.

Per Alberto C., don't apply grease/lube on the plates/rings.

Put everything together. Make sure everything is nice and tight. (adjusting ball diff is done at the track. I just make sure that it's not too tight or too loose while I'm on the bench) Also, dont forget to clean the bulk head using a Q-tip soaked with elec. cleaner before installing the diffs

and you're set! Thanks for reading !
