With restoration of the "outside" underway, works have commenced on examaning the Alco 251 prime mover to ensure all is well in the engine room.
Covers, rockers and injectors were stripped.....
...and heads lifted to check pistons and liners.
Preparations to line up the new conpressor have also been commenced.
Several components have been removed for overhaul and here we see the auxillary generator being lifted back for fitting.
With the aux gen back in place the real fitter returns to tune the engine...
...while others attend to changing the oil.
Diesel engines use injectors to put the fuel into the cylinder. Here we see another overhauled "rocket" being replaced.
