The Build – Part 6
Part 6 deals with building the DEST210R’s ball differential. While I could have incorporated this with the gearbox build, I just figured it would be easier to keep things short and sweet.
Build Notes: The instructions mention a ‘Silicone Grease’ and a ‘Molybdenum Grease’. Typically, Silicone Grease is clear so that was easy to figure out, so that would make the Moly Grease the green stuff. However, there was also a container labeled ‘Gear Grease’…looking VERY much like the Moly Grease. You will need to use this in a later step so don’t get them confused.
You will be using both black and diff grease while building the differential. Have some paper towels handy for esay clean up.
While I did these steps in the order presented, some of you might want to do Steps 53-54 up front. I was able to get the C-ring to snap into place easily but I can see how it might be a pain.

Take the diff spring and pre-compress it using a pair of pliers.

Open your Moly Grease and put a little on the outdrives where the rings set. Press the rings in place. The grease will help keep the rings from falling all over the place.

Once in place, coat the rings with the Moly Grease as shown.

Find your thrust washers and bearing and assemble them as as shown, making sure to pack it full of black grease (more is ok here. Be sure that the ‘grooved’ areas point towards the bearing. Slide this assembly down inside the ‘female’ outdrive.

Tricky-step time. If you have a pair of C-ring pliers this will be an easy step. If you don’t, not so much. Take the C-ring and feed it into the opening. It obviously won’t fit, but if you take a pair of pliers (or socket wrench) you can slowly work it down in the groove. It is extremely important that this C-ring snaps into the groove in the outdrive!

Take one of the 5x8x2.5 bearings and the 5x7x.0.2 shim and slide them over the nub on the male outdrive (no rude comments, please). Once seated, slide the diff gear on and over the bearing.

We want to make sure the diff had plenty of grease. Pack a liberal amount into each hole followed by the diff balls. You can also see the shim here from Step 55.

Slide the other 5x8x2.5 bearing onto the outdrive nub. Take the opposite outdrive and flip it over and into place, creating a complete differential. Make sure you keep the ‘flipped’ outdrive side face up…

…because that’s the side the Diff Screw goes through. Slide it through the diff, the Diff Spring and into the Diff Nut. Clamp the differential together and SLOWLY tighten the Diff screw into the Diff Nut. Continue to tighten 1 full turn, working the diff after each revolution. When the diff is tight, it’s ready. Since it doesn’t say, I’m suggesting backing the screw off about 1/8th of a turn. That’s about typical for these types of differentials.

Final step; Slide a pair of copper Shims on each side of the diff followed by a 10x15x4mm bearing. That’s it…you’re done. Set the diff aside for the next step as we assemble the complete gearbox.
