New drive units are shipped with temporary LH and RH mounts. Do not install these mounts in the vehicle. This section explains:

  • How to transfer the acoustic padding, coolant hose, and LH mount from the old drive unit to the new one
  • How to transfer the temporary LH and RH mounts from the new drive unit to the old one
  1. Drain the coolant from the old drive unit.
  2. Remove the coolant hose from the rear of the old drive unit. Note: This hose will be installed onto the new drive unit in a later step.

  3. Remove the LH motor mount from the old drive unit. Note: This mount will be installed onto the new drive unit in a later step.

  5. Secure the sling tool to the gantry.
  6. Lift the drive unit off of the transmission jack.
  7. Remove the acoustic padding from the old drive unit. Note: This padding will be installed onto the new drive unit in a later step.
  8. Position the crate with the new drive unit underneath the gantry. Open the crate and set the lid so the padding faces upwards.
  9. Prepare another padded area next to the crate lid.
Caution: Do not proceed until there are 2 padded surfaces underneath the gantry. These surfaces protect the drive units while the tilt lift extension is being transferred from the old drive unit to the new one.
  1. Lower the old drive unit onto one of the padded surfaces.
  2. With the new drive unit still inside the create, remove the top bolt that secures the LH motor mount. Note: This allows the tilt-lift extension to be secured to the new drive unit without removing the LH mount.
  3. Secure the tilt-lift extension to the new drive unit. Lift it out of the crate and onto the other padded surface.
  4. Remove the LH mount from the new drive unit. Install it onto the old drive unit, but do not install the top bolt at this time.
  5. Remove the RH mount from the new drive unit. Install it onto the old drive unit.
  6. Secure the tilt-lift extension to the old drive unit. Lift the drive unit into the crate.
  7. Install the top bolt that secures the LH mount to the old drive unit.
  8. Secure the tilt-lift extension to the new drive unit. Lift the drive unit to a working height.
  9. Install the acoustic padding onto the new drive unit.
  10. Place the new drive unit on the transmission jack and secure it with the strap. Note: Have an assistant guide the drive unit so that the ridge on the base of the drive unit fits into the fitting on the transmission jack
