TRF416 DIFF ? SAME AS 501X
I found those diff : http://www.speedtechrc.com/store/ebp...il.asp?id=9624
wonder if they fit in my 501x ?? thanks for your help ! steve |
The drive cups might be too small but you can use the pulley.

OK THANKS
|
i was looking at the same thing, though those drive cups on the gear diff are short, i think u'd have problems with the drive shafts falling out through suspension travel
http://www.rcmart.com/catalog/rc-trf...3-p-26528.html looking at those outdrives though, the cups look really long. is there anyone here with a 416 who could compare the out drives from it to the 501x / db01 please? |
are the pulleys the same on the 501x and 416?
it would have to be for it to start with, or near enough! edit.....,yes they are the same, hmmm.....got me thinking now. But then are the outdrives the same? if not, that its likely that it wont fit, without mods however. |
the diffs aren't quite the same, the slots in the outdrives for example are different widths because the 416 uses plastic driveshaft blades. I think you'll find the outdrives on the spec R diff are soft aluminium so running 511 bones with no blades would chop them up pretty bad. A lot of people have been having problems with the spec R diff failing too due to the plastic construction inside.
I'll try measure how wide the 416 outdrives are tonight compared with the 511 to see if they have enough length you can als mod the 416 pulley to fit an NT1 gear diff in 416, so you can potentially do the same with the 501/511 and that would be much more durable |
umm yeah you hit the nail on the head, and may stop me thinking about doing such a thing as well.
yeah thats true! An ally outdrive will last maybe 2 meets with a driveshaft with no blades. have not heard of the nt1 gear diff fitting the 416, need to look that up:thumbsup: however im sensing with all this trouble, may as well get a durango lol |

is there anything stopping us running the blades on the 501 driveshafts? if u have any info or a link about the nt1 diff, it would be handy thanks |
I don't think it would be hard to adapt one of these to fit...

I was thinking the 416 pulleys are the exact same as the 511/501 pulleys so are they different then? |
Pulleys are the same, I am not sure whether the bearing spacing is the same though.
|
.
I Think the spacing between bulkhead is +/- 18mm on the 501 compare to 21.5mm on the nt1 !?!?
|
Sorry to ask, but why would anyone have the need to change the diffs in a 501X? The diffs designed for it are already excellent..
|
I think its just another option for spares maybe

plus the diffs in the 501/511 need alot of attention just like any other belt driven 4wd offroad car as its susceptible to dirt. The enclosed gear diff would make it nearly maintenance free. |
what is the bearing spacing on the 416 will these diffs go in a 501.
|
It doesn't fit. Distance between the bearings is greater on 416.

DIFF
Hey guys,
i finally got my specR 416 diff * FITTED* to my 501x...and then to my DB01r i will take some pictures later tonight.... the car ran for the first time with gear diff... 1 word ! AWESOME ! (the fitment was quite easy,couple of shim..and 1 hour on my lathe !!! ) the pulley are the same from 501x / DB01 / 416 = 37 tooth ,same width Steve Laliberte montreal,Canada |
