As already announced, I had a professional sealing company make sealing rings for the LDU. These have now arrived. Haven't tested them yet but look good. They should work with or without Speedy sleeve. Very interesting! Anyhow, definitely experienced knowledge on installing tighter fit bearings wit...

I'm also interested in buying 2 or 3 for testing.

Just found these on AliExpress: https://a.aliexpress.com/_EvS09oh Single, double and tripple lip (CSL, CDL and CTL). Seller does't seem to have a lot of knowledge. Says that seals are for 5.000 rpm. According to the discription surface speed is 25 m/s (+- 16.000 rpm). He answers in Chinese (automati...

By the way: I’ve checked the speed sensor after driving 400 km with the new seal (Ceimin CTLBDYW). Well, that wasn’t what I hoped. There was condensation on the sensor. The drain was still dry (was plugged, so I would know how much it leaked). I collected about one drop of coolant when using some c...

One would think no as its the same PTFE lip material and the lips has more energized pressure against the shaft from the very beginning. This makes cause of @WimV's shaft damage all that much more mysterious. This was a rebuild DU, I wouldn't be surprized if the shaft had wear before the rebuild...

For the speedi sleeve: the flange is pre-cut (you can easily pull it off after making an incision. I do think speedi sleeve is not such a good solution because of the tight tolerances of PTFE seals (0,5 mm diameter increase is probably just to much). There is also a “speedi sleeve gold” that is coat...

In attachment some pictures of my triple lip rev Q seal with a small leak for at least 8 months. The seal is 5 years old and 77.000 km. All the seals are flat without concentric rings or other features. The seal at coolant side and dust lip were in pretty good shape. The middle seal was almost compl...

Worried reluctor chamber drain tap at bottom not enough? With that drain, won't get a pool of coolant for the reluctor wheel to agitate and aerosolize? I suppose no pool is great step with drain tap. Your thought if we can get to no collateral damage from leak so no need to repair leaky seal. Even ...

How did you prevent coolant from traveling through those sensor wires in future? It looked like the white sleeve is embedded in the stator, so I don't expect water to leak in the sleeve. If my seal is going to leak again in the future, I'm thinking about opening up the reluctor housing. There shoul...

Immediately after connecting the 12 V battery, the coolant pumps started running and the coolant level was lowering. I added about a litre before I started driving. I drove 20 minutes, the level was lowered again. Added again about a litre, so level should be the same as before. Until now, everythin...

I don't have a vacuum tool, so I'm just going to try to let it purge itself. There are temp sensors everywhere, so I don't think anything can go wrong when there's an air lock.

I drained about 2 litres, so I’ll be driving and charging slowly till I’ve topped the reservoir with 2 litres.

I used a wiring harness sleeve to pull the temp sensor wires through the tunnel, worked very well. The motor is assembled. Going to put it in the subframe now. How do you guys purge the cooling system? Is it necessary to fill the motor before connecting the cooling system in the car? Or will it purg...

Plugged the hole between reluctor wheel and stator, added vents and drains to reluctor housing and stator housing.

Now cleaning everything and reassemble (and adding a drain to inverter housing).

Which lips were most damaged? Theoretically the lip in contact with coolant will run a flim of coolant between lip and shaft for hydrodynamic effect to avoid burning up the seal. Since the other 2 lips has no hydrodynamic effect from coolant, I wonder how they survive? I just removed the seal. Star...

Yes, remanufactered

A few photo's of the rotor before and after cleaning and the seal. The rotor has way to much wear to use without sleeve or welding and grinding. The seal is a tripple lip. It's disintegrated pretty bad. Maybe the rotor already was rough when they rebuild it? I'm suprised there wasn't more leaked coo...

On speedi sleeve + Ceimin seal combo, did you see Boxster EV's leak experience and Johan's analysis? The main lip sealing off the coolant rides on the end of the speedi sleeve and probably compromised it. The sleeve is not wide enough for that seal. https://openinverter.org/forum/viewtopic.php?p=42...

I took apart mine yesterday. Bought the car in the beginning of this year, checked the speed sensor and noticed some condensation. Had no time to do the repair until now, so kept driving. Still drives fine without bearing noice or errors. The drive unit is a rev Q. Replaced under warranty in 2017 at...

Very interesting! I'm also looking for a quality seal. QC Charge claims to have them, but they ignore me if I ask if they're willing to sell them. They are familiar with Tesla LDU seals for a few years now. Do you mean that they have produced them before? Did they say for which company? Anyway, I'm ...

According to the seller, BK means "oil flooded" and should have a longer life. I don't know what they exactly mean with oil flooded. PTFE often has certain additives to improve friction and dry run, so maybe they mean an additive.

Thanks! There are 4 different versions: 30x55x8 CTLBDBK 30x55x8 CTLBDYW 36x37x8 CTLBDBK 36x67x8 UH5322-E Am I correct that 30x55x8 is the water rotor seal and 36x67x8 is the oil seal between rotor and gearbox? Any idea what the difference between both types for each dimension is? The bearings for th...

Thanks for the pictures! I've noticed some condensation on the encoder in my 2013 Model S (revision Q drive unit), so I'm going to rebuild my drive unit soon. It sounds and drives fine, so I hope there's not too much damage. What's your experience with the seal you've used? I would like to order the...
