Tesla Large Drive Unit Reman and Tuning - Part 1 

evclinic.eu/product/30x55x8-tesla-ldu-graphite-dual-lip-seal/

So you do sell this seal?

Less expensive than Tesla offering anyway

@@evclinic oh thats great to hear. So a perfect upgrade for a broken DU 👌

@@SgtFvMC yes, only if stator failed beyond repair.

After longer road test, 20000km made. And we are planing to make dyno test.

OK thank you, I will be waiting 👍

Zagreb, Croatia

Yes, that is possible.

Almost done, 25000km. Even bigger surprise developed.

You have link in description

I saw it on internet, but didnt see in real. Interesting, they must have read our letter but i am wondering what they did to limit rotor overheat. Probably 2-3 extreme starts will limit torque and power to motor. We have better solution which works and prevents any future leaks. And working on revision 2 for even better seal

My 2014 is going into the service center to have a remanufactured LDU Monday morning and it just so happens to be a "U" revision by the part # quoted. I'll test the theory that 2-3 hard pulls will limit power due to heat.

@@ferrynpalmer3875 And second theory is that overheat might damage Si rotor ballbearings.

@@evclinic .....ok. The replacement drive unit will be covered under a 4yr 50k mile warranty. I'll launch it all day and we can verify.

@@ferrynpalmer3875 Please 😎

Soon

No

I know, it can fail even earlier

When will this DU be available for the public? Is it possible to do this to the Sport Large DU? @@evclinic

@@daniellele9634 evclinic.eu/product/tesla-large-drive-unit-stator-tuned-re-winding/ Already available. Yes it fits in Performance LDU

Not completely true. Motors without rotor cooling they overheat and damage rotor ballbearing. Same what happens with BMW i3 motor, Renault Zoe r240 motor, Hyundai Kona rotor, and so on. All non-cooled-rotors fail below 100k km

@@evclinic This is not a specific unit problem, this is a BMW, Renault, Hyundai problem. Tesla M3, Y, S restyling, no longer have rotor cooling and run without gaps for a very long time, the Volt, Bolt, Nissan Leaf and many others are rougher, and besides, Tesla itself eventually came to the decision to abandon LDU rotor cooling. Change the bearings to steel ones and change the lubricant in them to a more advanced one and everything will work much longer, and besides, the malfunction of the rotor bearings can always be heard and replacing them is a simple and not expensive job, 100,000 km is a very good resource even in the worst conditions In any case :), this is much simpler than the problem with the oil seal and the consequences of its leakage.

@@Boris_312 But hey have oil cooled rotor.

@@evclinic oil cooled rotor LDU ?

@@Boris_312 No, you dont read. You mentioned model 3 and s Small drive unit, which are oil cooled
