As I am about to wrap up my build, I discovered a very small brake fluid leak from the upper NPT fitting going into the grove airfoil gear member. After lots of head scratching, I think I am going to have to drop the gear to get to the fitting.
That said, I thought this would be an idea time to change over to the NAS 1804-6 Nuts on the outboard fitting. I currently have the NAS 679A6 sent with the gear from Grove.
Does anyone know if the bolts will be long enough and if I need to change them, what bolts and washers do I need to use? It looks like the washers are key to a safe installation.
The inboard three bolts have the nylon locking nuts that come from Grove (or maybe Van's). Is anyone changing these to the 1804-6 nuts? Any reason to do so?
The Steve Smith, Bob Kuykendall study was really a first rate piece of research. My congratuations to them for their fine work. If I understand correctly, the issues and the study are all focused on the outboard bolts.
