Default Spur Gear Assembly question

As I was putting the Spur Pulleys, and spur gear, onto the Spur Gear Shaft there was no shaft sticking out on the other side to put the shim and E-clip on, the end of the shaft was flush with the bearing.

The button head cap screws that are holding the 2 sides of the spur gear hub together are hitting the spur pulley on one side and not allowing the pulley to go far enough onto the shaft to complete the assembly as the manual shows.

I'm could be missing something very simple since this is my first assembly of an RC car in over 25 years....and this is much different than the old 12th scale Associated and Delta cars of the early 80s.

I'm itching to get back to putting this car together so any help would be greatly appreciated.


Thanks in advance!!!

it sounds like it could be one of a couple of things

1. are the belts too tight, thus causing the centre pulleys not to match up, what happens if you lift the diff and spool out and then try to mount it

2. is the centre pulley mount in the right spot, what happens if you loosen the screws and then to mount it ?

This is the initial assembly, the belts are still in the bag at this point, I was at the point of installing the Spur Shaft E-clips when I notice no shaft sticking through the bearing to finish the job.....and now I'm here picking the brains of smarter people.

If the cap head screws were not there it would go together without any effort .....or dremel modifications. The book does show three cap head screws in the Spur Gear Hub final assembly.

are you using the button head cap screws? and the right length? the aluminum part should be counter sunk so they sit in the pully. any chance of post a pic of it how it is? you tightened them up good so it pulled together night right? the heads on mine hardly stick out at all. id say maybe blow it apart and start over. maybe somthing little your over looking

Using 6mm button instead of 5mm or the spur gear is too thick.

Thanks for the input, it sounds logical. I'll take another crack at it tomorrow morning.

Everything else seems to check-out, thanks to everyone that took time to help out.

what is the lightest fluid any of you have played with? the track i run at has pretty much no groove at all. and they change the track up every week so its pretty slick. im running the rsd 3x1.15 (i think lol) pistons and bladders and the rsd light blue(14) and white (13) springs and stock 40wt oil..was thinking about going white/white on the springs to. the car feels decent, but i feel like it could roll over a little more and grip a bit better

Default yoke springs qtn

i'm sure this has been asked before

but what parts do you need to make the yoke springs fit and not baggy on the shock. The yoke springs seem to be too big of bore. Do you need to replace the preload and shock retainer?

thx
