Tesla Model S: Mount - Front Drive Unit - RH (Remove and Replace) - Installation

Installation

1. Use alcohol wipes to clean the mating surfaces between the RH drive unit mount and drive unit.
2. Place a shear plate on the outboard side of the drive unit mount so that the shear plate bolt holes align with the motor mount bolt holes. Caution: Ensure that the bottom holes on the shear plate are not slotted. If the bottom holes are slotted, replace the shear plate with one that is not slotted. Note: Install a shear plate even if the original drive unit mount did not have a shear plate.
3. Insert new bolts (x2) through the lower holes in the shear plate and motor mount.

   

4. Set the new drive unit mount into position.

   Caution: Ensure that the bolts do not fall out from the drive unit mount while maneuvering the drive unit mount up to the front drive unit.

   Caution: Do not damage the RH axle during reinstallation.

   Note: The RH motor mount is reinstalled with the shear plate.

   

5. Loosely install the lower bolts (x2) to the drive unit.
6. Lower the vehicle.
7. Alternate tightening the bolts on the support jack to raise the drive unit. Have an assistant monitor the installation from the RH wheelwell and underhood area to ensure that the bolt holes align correctly.
8. Working from the RH wheelwell, hand tighten the bolts (x2) until they are snug; do not fully torque the bolts at this time. Tip: Install the forward bolt first. Have an assistant help align the rear bolt hole with the hole in the body.
9. Align both lower bolts with the front drive unit. If equipped, install the torque reaction arm shear plate on the drive unit mount. Note: The lower holes (x2) on the torque reaction arm shear plate are slotted.
10. Hand tighten both lower bolts. Note: The support jack might and/or drive unit might need to be slighlty adjusted when installing the lower bolts that secure the mount to the drive unit.
11. Hand tighten the upper bolts (x2) that secure the mount to the drive unit.

    

12. Position the 3 shim tools between the RH drive unit mount and body. Note: These tools ensure proper clearance. Leave them in place until prompted to remove, after all 6 bolts for the mount are fully torqued.

    

    1	2-pronged shim tool
    2	Hook shim tool
    3	Straight shim tool

    1. Working from the underhood area, position the 2-pronged shim around the RH drive unit mount front bushing.

       

    2. Reach beneath the drive unit and position the hook shim tool between the mount and outer bushing.
    3. Reach downward between the V-brace and cross brace and position the straight shim tool between the mount and inner bushing.
13. Working from the RH wheelwell, fully torque the bolts that secure the mount to the body (torque 120 Nm).

    

14. Raise the vehicle.
15. Attach the 15 mm ratchet tool to a torque wrench.

    Caution: Ensure that the attachment is 90 degrees perpendicular to the torque wrench when using the tool.

    Note: Only use the ratcheting tool on the front 2 bolts. Tip: A Crowfoot wrench can be used in place of the ratchet tool.

16. Fully torque the bolts (x4) that secure the drive unit to the mount in the order shown (torque 75 Nm).

    

17. Lower the vehicle.
18. Verify fitment of the alignment shims. Adjust as necessary.
19. Remove the shim tools.
20. Lower the support jack and release the strap from the drive unit.
21. Release the screws (x2) that secure the support jack to the cross car beam. Remove the support jack from the vehicle.
22. Install the bolts (x4) that secure the front fuse boxes to the front shock tower crossmember (torque 5 Nm).
23. Install the bolt that secures the coolant pump to the front cross car beam (torque 6.5 Nm).
24. Install the RH bolt that secures the A/C compressor bracket to the front drive unit (torque 10 Nm).

    

25. Reconnect the coolant level sensor harness.

    

26. Install the bolts (x4) that secure the coolant reservoir to the cross car beam (torque 6 Nm).

    

27. Install the fir tree clips (x2) that secure the 12V positive harness to the front cross car beam.

    

28. Install the 12V battery and bracket beam (refer to procedure). Caution: Do not connect the negative cable on the battery at this time.
29. Raise the vehicle.
30. Connect the battery coolant pump electrical connector.
31. Install the bolts (x2) that secure the coolant pump bracket to the body of the vehicle.

    

32. Install the HV battery (refer to procedure).
33. Lower the vehicle partially.
34. Install the edge clip that secures the coolant pump hose to the body of the vehicle.
35. Reinstall the wheel arch liner.
36. Reinstall the wheel.
37. Lower the vehicle.
38. Torque the lug nuts on the wheel (torque 175 Nm).
39. Connect 12V power.
40. Refill and bleed the cooling system (refer to procedure).
41. Reinstall any remaining components that were removed for access.
