I got a FW-05S, how much silicone diff oil should I actually put in the diff? A lot or a little?

I fill my diffs up all the way, reasoning is that by adding oil to change the diffs action it should be filled 100% so that the diff remains constant. ie, fill it up 50% the oil will be moving around inside and not providing a constant viscosity.

I was under the understanding that u fill to just above the gears but below the case line....

MrDurst

Well, the FW-05S has holes at the bottom of the diff that fix in to the chassis. So I guess fill it up using that hole then strap it to the chassis. right???

Maybe I'm sttooopid, but didn't know you filled the diff cases on associated cars??

I lightly grease the gear faces with clear lube, but I don't fill the cases with oil.

Do you guys fill Associated gear boxes?

NTC3 has Ball diffs, FW05 Gear diffs. It's gears inside it instead of balls. When filling the diffs you slow down the gears. Kind of tightening a Ball diff

instructions on my car say either use hobby grease(which comes in the kit) or use the oil(option). The reason I ask the question is that grease and oil are very different and I'm worried there wont be enough oil on the parts at any one time.

I wouldnt even build up the diffs with the stock gears. I did and after 1 race day they were destroyed! Go and buy the Kawahara steel diff gear option about $100.00 , good luck upgrading that car it cost a lot of $ to make the car competitive. I have 1 for sale I was completely disatified with the Kyosho, I will not stray from my Mugen again!
