Unfortunately I didn’t install either after poor results from flame spray shaft repair.

US flame repair shop don't care about precise LDU shaft seal application. Flame sprayed over the chamfer producing sharp edges that can cut the seal lip on install. Flame spray also produces tiny porous holes ...

@muehlpower if you have interest to further a robust seal solution, I have been making effort in US but maybe easier on EU side.

EKK has a very advanced coolant seal designed for electric motors. They have a 30mm ID x 50mm OD sample that can be supplied at volume for $120+. But it is not simple ...

Roadster has a 185kw motor without liquid cooling in rotor or stator. Looks like just heat exchanger fins outside of casing with active air cooling. Pic of motor in pg 2-3 of this link https://www.allaboutcircuits.com/news/teslas-roadster-motor-technology/ Tesla info (search for string "cool") https ...

QC Charge now selling coolant delete manifold for $600. Also have additional oil cooling loop kit. Note QCC said rotor will show heat marks with cooling delete. My rotor after flame sprayed shaft repair showed some rainbow color discoloration on the rotor surface from the heat. Probably sealer heat ...

Hello everyone, I joined so I could add the pictures of the new 1002633-00-U Base-Drive-Unit here for everyone. These were taken in an Orange County Tesla Service Center. This seems to be a brand new LDU made in 2023. T23*** printed on the motor end plate shows it was first manufactured in 2023 ...

Moodifying an existing manifold should be easy. The tube is difficult to press out, but shortening it up to the retaining ring should work. Then you only need a cover in place of the sealing ring that leaves enough space for the shaft and has a gap to the shortened tube. If the gap becomes too ...

There is no reason to run anything externally. The water comes from below, flows around the cover and exits at the top as before. Only the space for the gap could become tight, so it makes sense to drill a hole in the channel. The hole would then be where the word "seal" is in your picture. Ok I ...

The coolant delete manifold has been found. Looks like its on the latest Rev U LDU. Unfortunately, can't just buy the redesigned manifold from Tesla

UPDATE : Speedi Sleeve + SKF FKM seal leaked at 800 miles 400 miles - dry 800 miles - seal chamber drain tube showed coolant. Drained out ~1mL Impossible to capture everything so call it 2mL leak max. never drove faster than 80mph on highway Mid Inverter casing drain tap. No signs of leak Motor end ...

I have a Tesla Model S2014 Rear wheel drive LDU renovation ongoing. I just replaced the bearings and noticed that the rotor shaft is is very worn out by the seal so the shaft is uneven. I tried with speedi sleeve but it did not work- it still leaked. Therefore I have machined the shaft end to be ...

If someone wants to try a coolant bypass, I'd be really interested in how it works out long term. I guess the question is indeed longevity. Would be really nice to have an actual induction motor design engineer to chime in. Or even a non induction motor design engineer. I wonder if a temp sensor ...

Some additional info on skipping coolant cooling of rotor. Besides Tesla PN showing such manifold ( https://openinverter.org/forum/viewtopic.php?p=59851#p59851 ) Received recent contact from Model S LDU owner in Poland indicating Poland local EV repair shop is modifying manifold to bypass coolant ...

Summarized LDU rebuild seal rotor shaft decision choices. Probably 2 main options - If have pristine rotor shaft surface -> Ceimin triple lip seal without shaft surface prep - If poor shaft surface -> Speedi-sleeve (with sharp leading edge seal installation protection) + SKF FKM / @muelhpower single ...

I thought you may have used a linty rag to clean it from a previous pic you posted, that's disappointing. I think you'd be better off with an undersized seal area vs. how porous / rough the repair ended up. Most plating options will tell you to get the surface as smooth as the desired Finnish ...

Microscope Closeups of Metal Flame Spray Photo on 8-22-23 at 11.44 AM 2.jpg Photo on 8-22-23 at 11.45 AM 2.jpg I'm guessing - PTFE seal lip will not survive sliding over porous chamfer tip - pits (or filler) on the finished shaft surface (naked eye see as tiny specks on other wise smooth surface ...

Post Metal Spray Shaft Chamfer Analysis Here is what happens to the chamfer post metal spray Screenshot 2023-08-19 at 11.22.37 AM.png There are 2 problems - Since metal spray is porous, the chamfer tip is slightly rough unless cleaned up. Ideally, the tip would be rounded off slightly. - Chamfer is ...
