Bigbore preparing problems

[Fatal1ty]

Hi all,
I just finished my DEX210. What a nice high quality car! I'm really looking forward to the first outdoor season drive!

I got some problems, preparing my BigBores. I buildet them right, so short as possible, and all parts are at the right position. But I dont get them right.
After bleeding them, there is no oil in the highest 3-4 milimeter position, and the piston comes out the oil inside the shock body.
What am I doing wrong?
The biggest problem for me are the rear shocks. The front shocks are ok to make for me.



thanks!

The pistons only slightly protrude until the spring platforms are fitted I think. I've never had any problems with the shocks and Ive not done anything special when building. I always fill them a little too much and them bleed them through the bleed holes in the normal way.

hi i thought the same thing. it only happens on the rears. i build mine like this.

1. fill shock with oil to the top
2. move the piston up and down slow
3. once all the air bubbles have gone slowly slide the shaft so you have about 5 mm shaft showing (make sure the shocks are fully built.
6. leave the bleed screw fully tightened in place then screw cap in place
7. fit spring etc
8. pump the shock to build up the pressure

job done

as mentioned above once built the shocks work fine

y do u not bleed them?

Bleed them? No need if there is no air trapped inside. Bleeding allows you set the rebound to much and you loose all pressure thus no rebound. Shocks never used to have bleed screws can't see the point really. If you set the shaft to the position you want before fitting the cap it does the same as bleeding. But if you are not slow when bleeding you loose all pressure and rebound. Works for me anyway

+1 Thats how I built the shocks on my sx3 works perfect, I done my 410 the same way to with no probs...
