I will see what we get then and we will repair a steering gear on an E32 750iL, which should be the same as the one for the 850 (I hope at least, that the gasket set fits).

Just for info: the power steering kits are all same, no matter what BMW model, as long as the ZF pump has a vain diameter of 19 mm, even fits on some Audi models which have the same power steering pump, like the Audi Quattro.
Did meanwhile 2 pwer steering pumps reman, no big deal, easy to do, but you need a small press for the shaft seal, or DIY tricks.

Steering gear reman:
BMW still has some hundred gasket/seal sets on stock, p/n 32 13 1 134 768 List price 01/2008 EURO 37.40.

here I posted some pics from the overhaul
