  5. Remove the ECA.

    Note: The ECA has an alignment pin that requires the unit to be rotated to exit the Clutch Housing bore.

    Note: If ECA will not slide from the Clutch Housing after all the fasteners are removed, use the available pusher holes found on both sides of the ECA casting. Place the included jackscrews into the holes. Turn each jackscrew until it touches. Next, turn the upper jackscrew 1 turn; then rotate the lower jackscrew 1 turn. Continue until the ECA is fully displaced from the bore.

ECA Installation

  1. Install the ECA into the Clutch Housing bore. Align it with the lower Cross-Shaft.

    Note: The ECA will have to be rotated to align with the slot in the Clutch Housing.

    Note: Ensure you rotate the Release Yoke as close to the Case Dowel in the Clutch Housing prior to mating with the Cross-Shaft. This allows the Release Yoke to clear the Release Bearing during installation.

  2. Install the 4 cap screws from the ECA mounting flange. Tighten them to 35–45 lb-ft (47–61 N•m).

    Note: The cap screws for the ECA are longer than the ECA Bracket cap screws.

    Note: Ensure the ECA does not bind on the Cross-Shaft by snugging all cap screws before tightening to the specified torque.
