Removal Procedure


    Object Number: 66075  Size: SH

    Notice: When raising or supporting the engine for any reason, do not use a jack under the oil pan, any sheet metal, or the crankshaft pulley. Due to the small clearance between the oil pan and the oil pump screen, jacking against the oil pan may cause the pan to be bent against the pump screen. This will result in a damaged oil pickup unit.

  1. Using a suitable transmission stand, support the transmission assembly.
  2. Remove the bolts and washers from the rear engine mount.
  3. Raise the transmission assembly just enough to permit removal of the rear engine mount.
  4. Remove the rear engine mount.

Installation Procedure


    Object Number: 66075  Size: SH
  1. Install the rear engine mount to the transmission.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
