It's tricky to interrupt large DC currents, to effectively and reliably quench the plasma arc. Various magnetic and air movement techniques are used.

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

When you're installing a Speedi-Sleeve, it's to correct surface imperfections that would cause a seal to not work well. So I assume that the sleeve will not have great contact with the shaft, and will have the worst contact in exactly the area where you would want the most contact! I'm not saying th...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

Deciding to leave the retaining compound out isn't a great idea. The aluminum case expands much more than the steel in the bearing as they heat up. It can get loose / spin if you skip it. In fact, heating the case is the easy way to get stuck bearings out typically. To clarify again, Howard found w...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

The air I asked about was to allow coolant to drain out. Meaning that trigger wheel void area is able to easily suck air in from above the coolant that you want to drain. If the water manifold is siliconed in, it likely can't get air in the dry side unless it shares a breather / passageway. The ass...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

The thing I don't like about the trapped-moisture-between-lips-caused-rust-there theory is that there is a finite amount of oxygen that can be trapped, and rusting should cease once that oxygen has been depleted by . . . oxidation. The amount of rust I see seems inconsistent with trapped moisture . ...

Re: NACS Inlet Port options

you will need contractors to cut you AC lines when configured to DCFC In my case, I don't need to cut off AC when DCFC, because the Tesla OBCs always have tolerated HVDC at their AC input. That's the way the Model S (and our RAV4 EVs, which use the same OBC) do it. So when DCFC, just need to close ...
