When I was at work,I used to do a lot of large diesel engine rebuilds, mostly for shunting locos and large landfill gas powered generator engines.On one particular engine .a Rolls Royce V8, the main bearing bolts were torqued up to 1000 ft lbs, with a double barreled torque wrench.(it was enough to just collect the lump from the toolstore).What I used to do as there was no chance to use it as you normally would, was to turn the engine on its side on the build stand, and then use the overhead crane to torque up the bolts.Shame I couldn’t have gone and fitted the engine in Sri Lanka, seems an interesting place to visit if you are not paying,(no I am not from
Yorkshire)
