Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
These are the 3 coolant seals I bought. Single lip, double lip and triple lip. Time will tell which works best.

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
Thanks, that grease looks thick! haha Few questions - Did you mix it with the original grease? - Any longevity data? I guess need to pull again to see for sure.. PITA haha - Any thoughts on electrical conductivity characteristics? Thanks -I cleaned off most of the old grease but not all so a small ...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
Howardc64 RE: Spline grease. A good sticky grease used for propellor shafts is made by Overall Supply Inc from New Jersey. It is called "super grease" and is very sticky. It worked well on tug boat prop shaft bearings and seals. A couple other synthetic greases are made by Hydrotex and Cer...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
I'm going to try this 2 lip PTFE seal for my 2012 P85. It took 8 days to come in the US mail from New Jersey to the Chicago area. It ships with an internal collar spacer fitted to keep the seals oriented and stretched until installation.

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
Now that I'm looking inside the stator with a magnifying glass these metal shavings "hairs" sticking up look more like fibers from the insulating casing around the windings. They don't appear to be metal at all. It sucks getting old, haha.

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
howardc64 I had the gear case split apart. Inside the pinion shaft there is a steel collar that looks to be a grease stop for the rotor splines. It has a small hole in the middle so I screwed a self tapping screw into it connected to a slide hammer I made to pull the cap out. Then the rotor splines ...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
While cleaning the stator with an abrasive pad I noticed small metal shavings (hairs) sticking straight up from where the potting material was missing. (The grey strips in the picture.) I attempted to clean them out and apply some quick set epoxy but the metal filings stuck up through the epoxy as i...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
I got the gearbox and inverter put back together for my 2012 P85. All the bearings spun smoothly and had no play so I didn't replace any of them. My rotor bearings were the same. Johan mentioned in one of his videos that he damaged the dust seal on a motor bearing while removing it to repack the bea...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
After pouring WD40 in it last night and sleeping with this on my mind I came out this morning to find exactly what you described. I'm pushing on the pinion shaft. I will now attempt to remove the collar inside the pinion shaft so I can get to the end of the rotor shaft. I'll probably use a slide ham...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
Hello, I've been watching this thread for a couple weeks since my 2012 S with 180,000 miles threw some error codes and shut down. There was coolant leaking into the motor causing an isolation fault. This P85 large drive unit was last replaced in about 2017 and has about 80,000 miles on it. Using the...
