Tesla Model S: Locking Devices

General

Always replace locking devices with ones of the same design.

Caution: Do not use impact tools on fasteners that are threaded into aluminum components.

Locking tabs and washers

Always inspect locking tabs and washers. Do not reuse if damaged.

Pipe and hose unions

To prevent rotational damage to components, use two wrenches when loosening and tightening unions.

Nyloc and torque nuts

Discard and replace Nyloc and torque nuts after removal.

Encapsulated and Patch bolts

Discard and replace encapsulated and patch bolts after removal.

Locking compounds

Approved locking agents must be applied to some threads on reassembly where indicated in the procedure.

Note: If original bolts are to be reused, clean old compound off both male and female threads with a solvent cleaner and a wire brush before re-applying locking compound.

Note: Even if new bolts are being fitted, ensure all internal and external thread surfaces are clean and dry before applying locking compound.

Applying LOCTITE

Warning: Please consult the Manufacturer's Material Safety Data Sheet (MSDS) before handling any chemical product.

Leaving the first thread clean, a bead of LOCTITE should be applied to the complete diameter of the bolts leading threads for the first 10mm.

Loctite is a registered trademark of Henkel Corporation.

Flexible Pipes and Hoses

When removing and installing flexible hydraulic pipes and hoses, ensure that the following practices are observed to ensure component serviceability:

• Absolute cleanliness must be observed with hydraulic components at all times.
• Obtain appropriate plugs or caps before detaching hose end fittings, so that the ports can be immediately covered to prevent the ingress of dirt.
• Fit a cap to seal a hydraulic union and a plug to its socket after removal to prevent ingress of dirt.
• After any work on hydraulic systems, carefully inspect for leaks underneath the vehicle while a second operator applies maximum brake pressure to the brakes (servo pump running).

For information about assembling refrigerant pipes and hoses, refer to Workshop Manual.
