Procedure

    1. SUBTASK 72-41-34-040-053 Remove the Front Bearing Housing Assembly from the VSV Crankshaft

    1. Refer to Figure.

    2. Remove the retaining ring V2500-A5-72-41-34-01A-941A-D (72-41-34, 01-636) that secures the front bearing housing assembly to the VSV crankshaft.

    3. Unstake the hole which secures the location pin V2500-A5-72-41-34-01A-941A-D (72-41-34, 01-638), refer to the view at A, Figure. Refer to the SPM TASK 70-42-06-400-501.

    4. NOTE

      Keep the VSV crankshaft and front bearing housing assembly together as a set.

      Remove the front bearing housing assembly and the location pin from the VSV crankshaft.

    2. SUBTASK 72-41-34-040-054 Remove the Spherical Bearing Assembly from the VSV Crankshaft

    1. Refer to Figure and Figure.

    2. Remove the retaining ring V2500-A5-72-41-34-01A-941A-D (72-41-34, 01-623) that secures the spherical bearing assembly to the crankshaft, refer to Figure.

      3. Install the IAE 1R19464 Extractor to the crankshaft, refer to Figure.

      1. Screw the threaded collar into the support ring.

      2. Locate the fixed blocks on the reactor plate on each side of the VIGV crankshaft lugs at location C and reactor plate on face D of the VSV crankshaft. Refer to Figure.

      3. Attach the reactor plate to the lug (location C) with the bolt, washer and nut, support ring and the threaded collar assembly.

      4. Adjust the slide so the support pad touches face E. Tighten the nuts to firmly secure the reactor plate and slide to the crankshaft faces.

      5. NOTE

        Install the extractor in position over the VSV crankshaft from top side of the component.

        Locate the extractor collar over the outer bearing race and position the keep ring over the reactor plate.

      6. Attach the clamp over the bearing race and secure it to the extractor collar with the two nuts and washers. Tighten the two nuts.

      4. Remove the spherical bearing.

      1. If necessary attach and secure the hydraulic supply to the Enerpac RCH-121 cylinder.

      2. CAUTION

        YOU MUST NOT EXCEED THE RECOMMENDED HYDRAULIC OPERATING SUPPLY PRESSURE TO THE HYDRAULIC CYLINDER OR DAMAGE TO THE TOOLING AND COMPONENT COULD OCCUR.

        Operate the hydraulic pump to supply the cylinder with an operating supply pressure of 2,800 PSI (193 BAR) and slowly remove the spherical bearing from the crankshaft.

      3. Release the pump pressure and if necessary disconnect the supply from the Enerpac hydraulic cylinder.

      4. Remove the extractor from the VSV crankshaft and store the tooling in the special wooden storage box provided.

      5. Remove the spherical bearing from the crankshaft.
