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 !

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?

fastinfastout 02-06-2010 03:25 AM
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.

CraigM 02-06-2010 03:31 AM
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

fastinfastout 02-06-2010 03:40 AM
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

thanks so much for measuring up the outdrives for us, i will be interested to hear how close they are

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...

TA05 pulleys work
I was thinking the 416 pulleys are the exact same as the 511/501 pulleys
so are they different then?

DCM 02-06-2010 11:00 PM
Pulleys are the same, I am not sure whether the bearing spacing is the same though.

stevefreedom 04-06-2010 08:13 PM

I Think the spacing between bulkhead is +/- 18mm on the 501 compare to 21.5mm on the nt1 !?!?

dimblum 04-06-2010 09:04 PM
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..

T4miy4 Guy 05-06-2010 04:44 AM
I think its just another option for spares maybe

gear diffs have their advantages, look at the durango!

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.

discostu 21-06-2010 10:27 PM
what is the bearing spacing on the 416 will these diffs go in a 501.

_valtsu_ 15-07-2010 09:32 AM
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

interesting and looking forward to the pics!

is it possible to do without a lathe?

stevefreedom 16-07-2010 03:54 PM
well :cry:...i dont think so
maybe with lot of patience and dexterity w/ a flat file !??

discostu 16-07-2010 09:30 PM
yeah it can be done easily without a lathe i used a sharp stanly knife and a drill i then put a bolt though the middle of each diff half and spun the lip that needs to be removed down i done them in about 30 mins. as for better than a ball diff lack of maintance yes a good well maintained ball diff is easily as comparible stength wise the ball diff wins every time i striped my rear spec r diff on its second outing came off a big jump quite hard and stipprd it.

fastinfastout 17-07-2010 03:37 AM
2 conversions already, well done guys.

with the stripped diff, do you have a slipper?

im going to order a couple of these spec r diffs.

discostu 17-07-2010 05:46 AM
yeah and it was set correct the diffs are simply not strong enough which is a shame.

mof 20-07-2010 04:14 PM
I ordered my set of gear diffs today. :thumbsup:

They are not the ones mentioned in this thread, they are custom made by a Finnish company. Unlike the ones mentioned here, these should be rather bomb proof instead of plastic. The casing is aluminium and the gears are from a Xray nitro touring car, outdrives are custom machined Tamiya oneway outdrives, should hold up rather well :drool:

They should arrive this week, but I will not have the time to install them before next week... Should be quite a bit different to drive than my current setup with oneway on the front and ball diff on the rear :wub

Cos there are no links to it yet... so the post was more a teaser than anything else :) If there will be info released somewhere, it deserves it's own thread I think.

The production rates are currently not high, which means that the price is quite high (costs around 50% more than it does to buy all the parts for a ball diff with ceramic balls and thrust bearing).

Jan Larsen 20-07-2010 06:36 PM
I dont think many people here cares about price if it works.

interesting

are they custom made for this car, or do you mean its made for the 416 but then you will need to adapt to fit it?

spec r should really make diffs for the b44, 501x etc as im sure they would sell heaps

If I have understood it correctly, the diff casing is custom made for this car, but even if it were "just" modified from another cars casing (for example nitro touring car), it wouldn't really matter as long as it works, not to me at least.

I am not talking about the spec r diff, but another one that I ordered. The one I ordered is made for this car, and uses customized Tamiya oneway outdrives, Xray NT1 gears, and if I have understood it correctly, it uses a custom diff case, but of that I'm not sure.

Edit: Confirmation, the diff case is custom made for this car, not customized from another case.

Jan Larsen 21-07-2010 08:34 PM
Keep us posted on that mof. Very interested in one to test out if it works.

hey stu, can u just explain the lip that needs to be cut down, does cutting that lip down allow the diff bearing to be pushed over them. Also can you offer some more details of the diff being stripped, was it some internal gears that went? what motor were u running, im thinking for a stock application, it could still be a worthwhile endeavour

thanks

yeah if you cut the lip down the bearing slids on futher allowing the correct gap as for the stripping yes it was the internal gears and it was running a 13.5 spec motoron polished floor with some jumps they simply are not up for the job.
