Are you guys finding that the diff on the 415 needs frequent rebuilds? I redid mine with new rings, balls, and pulley, and 4 runs later it feels really gritty again. This is really disappointing, especially since my Evo 3 and TA-04 diffs stay really smooth for a really long time. Any suggestions would be appreciated. I'm using stealth lube on the main balls and black lube on the thrust bearing.

Hi Gary,

I've got about 8 runs on mine I think, and still feels new. I used the Atlas Diff Covers, Steath on the balls, and AE Black on the thrust bearing. I'll have to report back after another 10 runs or so, but I think the diff covers make a big difference. They were stocking them at So Cal.

Mine is still good........ I just clean it out every so often. Have you tried making those lexan sheilds everyone is doing? I was thinking about trying that.

I had the same trouble, and I think i've traced the problem to the internal diff bearings. I flushed them out last night whilst i had my diff apart, and whilst they span ok, they were gritting a little. I'm going to get some replacement ones as soon as i can, and i'll see if that has an affect.

Also, following advice from on here, I'm now using a very thick Anti-wear grease on my thrust race (which was a brand new one for install last night), so hopefully that will last well now.
(FYI I'm using the Tamiya diff lube on the main balls).

Deffiently try the covers as well, if anything it better protects the rings and balls (I made some custom ones up out of thin plasttic sheet, and superglued them to the diff pulley, match the delrin outdrives well )

Actually on another point whilst I had the diff apart, i checked the seating of the rings. One appeared to move on it's seating, as if the retaining part on the outdrive had worn, very strange. Anyone know how badly this will affect performance of the diff (I'm going to get some new outdrives anyway, just don't have time for this weekend)

Hope it helps
Ed

Do you think Tamiya will make yet another version of the 415 where there's easier access to the diff and spur gear? The Hot Bodies and Yokomo cars look real nice in that regard. I don't think it will take much effort to make those similar changes.

Is that for a pair of covers or do you have to buy them individually?

It's actually for 4 covers, enough to do 2 diffs.

This is on indoor carpet though, so I don't think it's a matter of dirt getting in there. I almost think it's a matter of the grease getting flung out. One other note is that it wasn't as bad with a stock motor, but it happened really quick with a 19T.

BTW, those diff covers won't do me any good since they're not TCS legal

Gary, the covers will do wonders. Just try them and you will see. Running at socal the track is pretty dame clean but stuff like tire wear will get crap in the diff over time. I am sure it's the same way with carpet. Especially with fiber and whatever that is inside the carpet. It's not TCS legal but I am sure you can take them off for the race. That diff should last for a few runs without cover.
