Don't overfill it, as most of the time, what we think is leaking is actually just seepage from overfilling the diff.
Ahh nice to hear! I put x ray 2k in it and greased the out drives as well as the o rings heavily. Do you know what size they are by chance and do you use the oem gasket or have you found something that isn't paper thin?

Use the red 5mm Kyosho O rings in the diff, it will instantly stop leaking after. No grease required.

As you can see on the picture below! ;-)
very clean build mate...

im running spec-r Front Spool with spring steel cup now...more durable cup than the Stock one. and the best thing is it's dont use pin, it's use screw to lock down the cup into the spool holder!.

Just a quick one bd7 lovers, after I built mine awesome (crap shocks) IMO, I played with spur gears.
Now I've been racing 15 years and for as long as I can remember I have used rw racing for spurs and pinions
I have never stripped a spur nor had a poor quality one. They are light and ultra strong
So I know people are saying some spurs work some don't, xray do etc etc.

I made a call to neil at rw racing after I measured and worked out what's needed (writing it like that makes it sound more difficult than it was really)...
He is making some spurs for me to try for the bd7, I'm sure of my measurements so I'm confident.
With the standard spur the screws made contact with the pulleys and did not seat properly as I'm sure those who have played would know.

Anyone with rw 008 offset spurs its the same concept design, as I had them done.
They are 4 screw design and 80 to 120.... Plus teeth,3 mm thick I'm sure he will do 48 and 64 dp mine are 64 comin
I will let u know tomorrow. And attempt some pics if i can load up
P.s any one not running rw pinions, get them and try the hard light weight ones the are ultra light and perfect pitch. Great company great products.

The normal rw spurs work just use associated bh screws.

What's the height of the head then? I have tried 3 possible 4 different manufactures, including ally and titanium the heads a too big. The screw heads butt up against the pulley no gap! And pulley not 100% on hex.......

U must have different pulleys possible the 008 ones? Issue with that is the internal thickness of the spur is .2 mm thinner, also the screw heads would sit really close to the edge of the lip. Or it's not rw spurs... I have tried 2 and 4 hole none have a "proper fit".

Ive never had an issue with the gasket, just replace it when it gets squashed a bit.

If anyone is having trouble building the shocks, get rid of the blue bladders, they are pretty much useless. Get the black ones and replace the bottom o-rings with the optional ones. You wont say anything bad bout the shocks again
