RB5 Build Tips

[jim76]

the associated tungsten carbide balls are pretty good, probably better than the kit ones. ceramics just last forever and hardly ever need a rebuild.

when building the shock body (p20, no.30), what does the oring do?
ensures the collar doesn't move?

the o-ring is preventing me from adjusting the collar .. i cannot even turn my collar up (to lower the car) once the collar has covered all the thread .... something must be wrong somewhere.

yes the o'ring stops the collar from loosening during a race and therefor moving unwatedly.
Did you put some oil on the threads before you started to put the colar on? This adds lubrication to the shock body, making it easie to put them on and gives you less chance of cross threading the whole thing.
Hopefully you haven't already cross threaded them and thats preventing you from screwing the the collars up.

Mine went on fine with the oil on, but are a little tight without it, but not imposible to screw up or down.

check for cross threading. hopefully its ok.

the manual also showed another plastic part as well as the adjuster. I think this was a mistake in the manual as this part doesn't go over the threads so makes adjustment impossible. I just didn't use it!

yes .. that's the offensive part # 109


yes, i did apply oil on the o-ring before adjusting the collar.
funny, i just have the problem on both front shock bodies. the rear ones are ok. what the ..

will have a look at the buggy again.

btw, found this on the rc-car setup website.
on the front shock tower .. see how the collar is positioned the right way? the little sleeve is facing downwards?





see how it is on the rear?
the collar seems to be inverted, the sleeve is facing upwards. i have a similar problem, but only the other way around (i.e. on the front shock bodies instead of the rear).
perhaps i got my shock collars mixed up.
but i wasn't aware the shock collars were for specific shocks and not interchangeable

[jim76]

the shock collars are all the same. do idea why this guy has his upside down on the rear, the springs will rub on the shock body. Possibly turn them upside down if you need to wind the thread right to the end for maximum ride height. turning them this way up will give you a fraction more height without the collar losing the thread.

Just a quick one on the upturned collars...

Mine is the opposite way around, facing upwards on the front, simply because one of them cross threaded when I put it together out of the box.
For some reason the collar will go all the way to the top when screwed on upside down, but for the life of me, it just won't go past the O Ring when screwed on the correct way round.... Even with a ton of lube...

There could be an entirely different reason for the guy in the picture, but that's what I've found....
