It iscomparatively easy to strip the cab and fittings which wouldhave to be removed in any case, and little time is recjuiredto cut off and punch out the rivets. Then the work of ap]ily-ing a new firebox, leing ])erformed in the boiler shop, is. Fig. 2—View of Boiler with New Firebox Applied conveniently located for workers and supervisors. When thenew firebox is applied, the back end of the boiler is sentback to the erecting shop and fitted in place, new rivetsbeing driven in the old holes as shown in Fig. 2. This method of renewing fireboxes has a big advantage,both as regards labor and material costs, over the formermethod of disconnecting and removing the entire boiler fromthe engine frames. In that case it is necessary to strip thejacket, lagging and fittings from the entire boiler, all run- ning boards and brackets also being removed. Cxlindersaddle bolts and expansion pads must be removed. It takes two men aljout 16 hours to disconnect and removethe back of the boiler, as shown in Fig. 1, and about 20hours are required to put it back in place and rivet it, asshown in Fig. 2. The old method of removing the entireboiler would probably take four men about 24 hours andapproximately twice as long to put it back on again,
