FWIW, here's a Highland Argon 1st disassembled with service parts ID'ed.
I haven't seen a manual, but personally, I'd lube both the DIN Wheel Retainer threads and the Piston Cap threads.
I'd pick about 80 in-lb for the DIN Wheel Retainer, and of course firm metal-to-metal for the Piston Cap.
My old reg currently yields about 90 psi IP with those two shims.
If you don't have access to a Trident dealer, DM me and I can put a service kit together with Viton o-rings and those two Trident parts for $20.
Hand cut extra shims, extra pesos.
