This patent describes a boring machine for boring in situ spaced axially aligned bearing housings on an internal combustion engine body after removal of a crankshaft from the engine body. The bearing housings include a pair of opposed end bearing housings and intermediate bearing housings between the end bearing housings. The portable boring machine comprises: an elongate rotary boring bar mounted concentrically within the bearing housings and having ends extending outwardly from the opposed end bearing housings; an end mounting member wholly supported by each of the end bearing housings and positioned between the boring bar and the associated end bearing housing for supporting the boring bar thereat. Each end mounting member includes an inner concentric portion engaging the boring bar and mounted for rotation therewith, an outer concentric portion engaging the inner surface of the adjacent end bearing housing and permitting relative rotation of the inner concentric portion and the boring bar, and adjusting means.
