Repair in London

[Isroslav]

I serviced my B250e and I'm happy. They dried it out, replaced the bearings, checked everything, replaced the seal and much more. If you need help with repairs, write me a private message! In london

I would remove the coolant manifold, chop off the rotor coolant tube as it's not needed, grind the rest of the tube down to the base and fit a cap with sealant. The coolant would still flow under the cap via it's normal circuit. No more coolant leak worries.

If you say so, then you do not understand the principle of operation of the cooling system in this engine...

What tankmania described is more of less what I did last Spring, and what a lot of LDU owners are doing. You lose rotor cooling but retain flyover tube coolant flow, as well as stator & inverter flow. I had a slug of alum. machined for a cap, but there's an inexpensive stamped SS sheet metal cap available nowadays.

As Tesla gave up on trying to make the rotor seal work on their Reman units, this doesn't seem particularly dangerous: eliminating rotor cooling.

See for yourself, as it is more convenient for you. But still do not worry. Our service in London is engaged in rewinding the stator winding, it will be completely new with factory characteristics.

You have shared very detailed and comprehensive posts on various options explored by many in different forums. No doubt it took you a lot of time to document along with many photo's, all to benefit many. Thank you for sharing, I appreciate it

Isroslav - Well what is described regarding the "Coolant delete" operation, with modification of the coolant manifold - that is what Tesla is doing when delivering refurbished engines, and have done for a while.
They realized that they could never get a proper seal, and therefore made a bypass for the coolant.
