I have already posted threads on this subject under a specific part of the operation and thought it would be better to post any further threads under this title. I am in the process of removing the boiler to go down to Western Steam so they can ascertain if it can be repaired or if I need a new boiler. I have been told it needs to be completely stripped down which I am doing. I have removed most of the boiler fittings and the only thing left to do is to remove the regulator which I need advice on. On the regulator block photo I have circled in red what I thought might be the nut circled in red on the drawing I have attached. Does this need to be removed in order to slide out the rod and detach the rest of the regulator. As you can see I have already removed the cover. On the regulator block photo I have circled in blue two screws, do these need to be unscrewed as well. On the regulator backhead cover photo you can see I have circled in red four small bolts. I am assuming once the nut or what is holding the rod at the other end has been removed these bolts can be removed and the regulator slid out from the boiler. One last thing are the super heaters just pushed into the boiler tubes and by undoing the nut in circled in blue on the super heater photo the boiler can be removed from the loco. I look forward to any replies.
