That is so funny. I have the exact engine disassembled for upgrades. To remove the boiler/cab, remove the front truck. One brass screw holds the boiler in front. The two screws next to the rear connector hold the back end.
as for the chuffing, there’s two micro switches. One for two chuffs per rev, and another for four chuffs per rev. I have removed the selector switch and hardwired for four chuffs. Done the same with the smoke unit switch. Removed and hardwire since I only run command. The turbo smoke unit is connected to the chuff micro switch. Oh yeah, micro switches and cam lobs are on the front driver.
Im installing GRJ super chuffer and fixing a rear driver that out of quarter. Keeping EOB as it works just fine, and will be changing the railsounds.
