Differential Drama Day
The diff on my Tamiya TRF415-msxx was a bit gritty today whilst racing, so I swapped it out after race 2 today. I put in a unknown 2nd hand diff I’d picked up, it felt okay, so went with it.
I cleaned and rebuilt the other diff, and it felt okay, so put it back in the car, but a run later and it was very notchy again, so the spare diff went back in Unfortunately, the spare diff managed to loosen itself, the nyloc nut was worn.
So I fiddled with the other diff some more, and got it smooth again, and back in it went.
Yes, you read all that correctly, I swapped diffs after every run. And in the last run, the diff failed again, notchy once more.
This evening once I got home, and messed about with all the diff parts I’ve got, and ended up chucking out 2 sets of ceramic balls (notchy, flat spots I guess), 3 pairs of plates (both sides pitted and used), 2 nyloc nuts.
I was left with a complete diff with ceramic balls and thrust, and a good enough nyloc, and it’s very nice now.
Spares didn’t quite go to a spare diff, I was a nyloc nut short of making up a spare steel ball / steel thrust diff.
I’ve ordered up some spares: a JAAD ceramic thrust, some EDIT ceramic balls, some Tamiya plates, some HPI nyloc nuts, some Tamiya sticky covers. ie Enough to make a spare ceramic diff and some other spares left over. That should get me through a good few months I think.
(And I won’t even talk about the front driveshafts… or the end result…)
