Thanks for the great video. The tech I have work on my Model 3 recommends changing the oil and filter every 30k miles in the drive units. (Retired Tesla certified Tech)? He also says that in the annual maintenance is very important to visually inspect the drive units for leaks as well as all the suspension bolts for tightness. He also says that it very, very important to do a weighted wheel alignment as it has been his observation that the factory alignment is not very precise leading to premature tire wear.
@@rienkvandenberg9103 Thoughts: which exact conditions would cause the rotor to overheat and damage when deleting it's cooling? If it only means that you can't abuse the car on a race circuit but all other everyday use is fine, then the deletion is preferred over seal replacement.
@@diyEVguy Someone told me that this motor is only rated for 30kw constant. But peak power is almost 300kw. I think cooling is very important even for daily use if you like to accelerate fast.
Thank you for the great video. I appreciate that you included the torque specs. Did you happen to find any part numbers for seals and bearings, as well as places to buy them? My biggest concern is finding the seal at the end of the coolant tube that that runs down the rotor. Thanks!
I bought Chenming seals through aliexpress. I want to discuss those in a next episode. Bearing: not sure if I need to replace them. I will share the model numbers though.
Your videos have been extremely helpful. I’m though currently trying to remove the small pinion gear next to the middle gear though cannot since I cannot take off the 3 bolts on the middle gear. The rotor has seized in places because of coolant and will not allow me rotate the rotor to get to the bolts middle gear. Any idea what to do in this situation?
I got to hand to the Tesla engineering and RD department, this is a well-built piece of equipment. No wonder the Tesla automobile is so popular, excellent engineering.
@@diyEVguy The care and precision and patients you need to work on these units. One thing I got out of this is that this is not a DIY project. If you have a problem with your electric car please take it to a professional technician.
@@ohger1 When it fails, the red Dexron VI fluid would gradually flow into the rotor chamber and next also into the inverter. It is non-conductive, so it should not short out electrinics, I guess. This continues until the gearbox runs dry and then your bearings may die.

parking mechanism is used on rav4ev and b250e, yes, model s/x does not have it.
Cost reduction.
The parking brake seen here is also used in mercedes with tesla large drive unit
Correct
@@diyEVguy What do you think about the coolant delete option?

thanks dutchie, goede info
QC Charge in Cali has a coolant delete kit that prevents inverter death! I think they have a bearings and seal kit too but not sure.
Who developed it? Tony or Tesla?
Just superb instructions video!
Thanks!

Thank you! Sorry I do not have a good answer. Maybe ask on teslamotorsclub.com?

What aspect do you admire most?

@@TOONMAN200 Yeah in general, for most people, that is the best advise.
I see you have a acent. I used to be a mechanic might go back ..part time. I did everything long time ago!
Yes a Dutch accent.
impressive
Thanks!
Why there is no o-ring 8:20? But in the other video it is in complectation?
The ring sticks to the bearing by the oil.
What symptom was seen before the unit was pulled?
Coolant on the speed sensor. See also my very first video.
Actually for this seal no symptoms at all, I just stumbled over it.
@@diyEVguy Thanks, I subbed and will check the other vids. I wonder if that bad seal would have no symptoms or cause no problems.

@@diyEVguy Thanks for the info.
Where are you guys located. I’m looking for someone in south Florida who can do this kind of work
I am in California. Try "Electrified Garage" instead.
@@diyEVguy thanks. I will look for them
12:17 mb the grease is the same which u already repacked in the bearing skf
Are you saying that the bearing grease can be used for the spline too?
@@diyEVguy yeap :)
hello! how many sealings we have in ldu?
4 (excluding all rubber O-rings)
I se SKF bearings made in USA inside the gearbox
Yes, see also more info and discussion about the "Country of Origin" here: sites.google.com/view/teslaldu/parts
