gear conversions Part 2! Need your help please!

[Cooper]

well!

as you might know (or don't know)
I made the conversion for the old cars to use Tamiya gears in it.

well now I want to make it even more simple, use X10 gears but without replacing the whole transmission.
And you can help me with this (because I don't have an X10 or XRS)

What I need is:

1 broken(or new) pinion gear
1 crown gear


it's no problem when they're damaged, it's just for fitting them and making measurements.

I'll pay you shipping costs if you want

so if you would like to donate me these pieces i'd be very very thankfull!

greetz,

the big problem you will find coops is that the X10 diff is close to being indestructible - i don't think anyone has broken the gears yet!

well i've heard of some lugs that broke off from the pinions when people didn't use that ring.
;D

[chris burgess]

indeed so have I! I had forgot about those breakages, but they were soooooooooooooooo long ago!

And if you send them back they get replaced ;D

I have broken them with the ring fitted, loads of power!

aaah If I email ttech they won't answer anyway

well.... so I must do this on my own! but I need the help from you guys who've run the pre X10 versions.

I'm going to order:
2 pinions
2 crown gear
gear collars
spur
2 Bearing Flanged 6x12x4



I'll just use old outdrives etc and put the new crown gear in it, next step will be dremel the chassis I guess...

next step is to dremel a 1mm piece of that 'thing' on the one way and rear coupling that slides between the pinion lugs. (you know what I mean I hope) because the new bearing diameter is 6mm and the old is 8mm

install pinions


shim everything out


BUT

I need to know some things before investing in this...
is the diameter of the pin that goes into the pinion still the same?
is the rear coupling form the X10 longer/shorter than the old P8? or is only the part where the pinion slides on different? (like I hope it will be)


thanks in advance!

Coop, the inside diameter of the steel pinion is 3.99 mm, I just measured it. I don't have a P8 so I don't know if its smaller or not, or if the coupling is longer than on the P8, sorry.
