A quick review of the plans, it is 240 INCH-LBS.

I am assuming with this hardware it's the same. Anybody retrofitted from a completed airplane? How much "fun" was it?

Thanks!

FWIW, mine (replaced nuts) have not budged in years and I likely have the heaviest repeat load tests on the plane being a Super 8 with 84gal of fuel. There is no question that after the stock nuts, replaced a few times, kept loosening, this is fixed.

After reading all these posts, I ordered 4 NAS nuts from Aircraft Spruce. They are not cheap but insurance will cost some money. I haven't mounted the gear yet but I like the idea that I only have to torgue these nuts once and they should be tight for years.

Even if these nuts stay put, don't forget to (as per Van's instructions):
"Check these bolts and re-torqued after the first ten flying hours, then again
at 50 hours, and annually thereafter. Failure to do so could lead to premature wear."

I canít remember the details but I replaced the bolts with the next longer to get the required thread protrusion.

Mine is not flying yet, but should be within the next 4 weeks (depending on the Virus-Thing development).
However, whilst fully assembled (and standing on the gear) i switched to longer bolts and the stronger nuts. That wasn´t a Problem at all as the gearlegs are hold in place by the single big bolt and the U-804 inboard main gear attach bracket. The aircrafts weight actually pushes the U-801-L/R gear leg firmly against the U-805-1 outb wear plate.
I removed one bolt at a time and replaced with the new Hardware thightened them and torqued them when both bolts&nuts where replaced on the same side.

No biggy, if you neglect that i do not have the tower mods done. You need two persons though.

Just make shure that the Aircraft is unable to move while you are on it.
I put mine in Level-flight attitude (put the tail on a sawhorse) to have the load of the gear coming in perpendicular onto the U-805-1 outb wear plate.

One might argue that the torque value is not correct because the whole assembly is pre-loaded……….i did it anyways and will re-check after taxi tasts have been completed, after 10 and 50 Hours and then annually.
