Removing rotor and leaking seal from Tesla LDU

In this episode, I remove the rotor from the Large Drive Unit and the leaking seal from its housing. By brute force. Learn and do better :-)

Coolant seal removal:
● Possibly a more controlled way ro remove the seal: Drill and mount 2 or 3 regular sheet metal screws (not-self-drilling, non-self-tapping) and pry each. - Thanks to Al Savage
● Drill 2 tiny holes in seal. Next, slowly screw in two #8 wood screws until they hit the housing. Then keep turning slowly both screws simultaneously by alternating. Now the threads push the seal out. - Tip from Kent Patterson (LakeCountryEV channel)
● The coolant seal can be removed using a "seal puller" (Google it!). This is way less destructive than using a dremel tool. Tip from Dan K

Reluctor wheel removal:
● Use a windshield wiper arm puller. Example: https://a.co/d/99PxEVE
First, grind away the four rivets and replace them with nuts and bolts, otherwise it's impossible to push the puller's "teeth" through the reluctor wheel's slots.
Reluctor wheel disassembly procedure (if I understood Dan correctly):
1) Separate the bolts/nuts/jaws from the puller,
2) individually push the teeth of the separated jaws through opposing reluctor wheel slots (each ~0.6" wide),
3) assemble the puller with the nuts and bolts (while fingers are still in slots),
4) put a sheet of soft material between puller and shaft (to protect the shaft end),
5) pull out reluctor wheel by rotating the puller handle.
Thanks to Dan K!
