Does anyone know the size of a socket required to fit the large bolt/nut on the front of the crankshaft of the Perkins Prima 60? Also, are the glow plugs metric or Imperial? I would like to remove the glow plugs, get some oil into the cylinders and roll the engine over by hand before trying to start due to the extended layup. (If the glow plugs are too tight, I will remove the injectors) I cannot seem to find these dimensions searching online.
