Well I wanted to finish building the shocks on the Pro-4 today and guess what, the treads on the inside of each shock cap are not all there. I have 2 shocks that I cannot tighten the caps on fully and they leak because there is no force against the plastic mounting collar to the bladder seal. I am starting to wish that I had bought the Tamiya Evo-4 instead.
I think I know what you mean. When you screw the cap it is not tight against the lip on the body? See the arrow. Mine is not either.
You will get some oil come out the vent hole on cap if you start with the much (I always start with to much and let it bleed out). After that, just tighten the cap, work the shock shaft up and down, wipe off the excess oil (I like to use a paper towel with alchol on it to get the oil off). There should be not leakage then.
Do you mean part A787 has no threads?
take care
