So I got the CTIS wheel valve assembly installed. The O-Ring in the elbow is obvious now, but before I understood it was there it felt as if the threads were not mating properly, like a cross thread or wrong thread pitch. Thanks to advice from the General, I got it on.
I'd be lost without the advice I'm getting here. Thanks so much!
I inflated the tire, but the wheel valve assembly is leaking. I received the rebuild kits I ordered, but in the meantime, I've placed an order for new CTIS assemblies, which are expected to arrive next week.
I left town for a trade show in Las Vegas, so the right front tire is on a jack stand and leaking slowly. It'll for sure be at zero when I return. I'll put the new wheel valve assemblies on and try again.
Before we left, I had some help, and we mounted another tire which is now ready for the CTIS wheel valve and inflation next week.
So I'll have two good tires on the front next week and 4 more new tires with 2022 or newer birth dates arriving next week as well.
I'm hoping to drive it to the scrapyard to get the 5th wheel plate off by the end of April. I'll drive it around the block a few times before then to test the brakes and get the feel of it.
