I'm gonna try to explain the process and tips i've found that helps me to get the job done, i haven't seen any topic or video explaining this so i hope it helps.
1. Remove the HST adjuster. In this case you can see i got the golden one but it may vary with a black steel one. In case you have the black HST adjuster you're gonna have a hammer weight instelled too that will come out when you pull the adjuster and spring out. Some R400 have hammer weights, all R500 and Boss have them
2. Remove the trigger. See this topic ----------> Royale trigger after a couple thousand shots[/QUOTE]https://www.airgunnation.com/topic/...uple-thousand-shots/embed/#?secret=gq45rccXtg
3. Now that we have the trigger out we will be able to remove the hammer. In this pic we can see: brass hst adjuster, washer, hammer spring and hammer. The hammer weight would be between the hammer spring and hammer acting as a spring guide, that's why you will need the black hst adjuster wich doesn't have a spring guide built in.
4. Remove the two screws on the upper part on the block wich holds the lever guide and lever itself to it's pivot point
5. Carefully pull the plastic lever guide out using the angled side of an allen wrench from the buttom of it, it can be quite tough tho so be patient.
You can then remove the side lever and pellet probe without effort
Regarding the lubrication now, the only parts i lube are marked with a circle. In the red one i use moly paste (metal to metal contact) and in the green one i use silicone grease/liquid silicone (plastic to metal). I've tried using moly paste in boths sides but the side lever was becoming sticky and not too smooth
Another important conclution i reach was that the hammer and the chamber where it slides needs to be completly free of grease or any kind of lubricant, otherwise it will slow the hammer down when striking the valve loosing velocity and increasing ES.
To reassemble just reverse the steps
I hope you got me
p.s. i've found the liquid silicone thing is actually not necessary, the moly paste in the parts i mentioned above is just fine
