Install Tooling (B) onto the studs for the crankshaft main bearing cap. Tighten threaded collar (1) of Tooling (B). Loosen threaded collar (1) of Tooling (B) by 1 1/2 turns. Attach Tooling (C) onto Tooling (B). Attach Tooling (C) onto Tooling (D). Attach Tooling (D) onto Tooling (E). Apply approximately 135 MPa (19580 psi) of pressure to Tooling (B). Use drive (2) on Tooling (B) to loosen the nuts for the crankshaft main bearings. Turn drive (2) on Tooling (B) by approximately three turns. Release the pressure on Tooling (B). Remove Tooling (B). Repeat for the remaining main bearing caps.Note: Refer to Reuse and Salvage Guidelines, SEBF8301, "Inspection and Reuse of Critical Fasteners in All Engines" for reuse criteria of main studs.
