Onbekrachtigd E36 huis heeft veel omwentelingen ik dacht 4,5 of 5.
Dit is wat ik kon vinden over een stuurbekrachtiging uitschakelen:
This is no big deal. See, most BMW technicians have no experience with this sort of thing -- only track junkies, race teams, and inveterate cheapskates want to delete E30 power steering. In terms of the first two, it makes good sense on the track because you can eliminate one possible operating fluid leak, some underhood clutter, about 10 pounds of useless (on the track) weight, and free up a small amount of parasitic power that previously went to spinning the power steering pump (a very small amount). As for the inveterate cheapskates, trust me -- you can't tell them anything anyway. However this is one case where the cheapskates aren't shooting themselves in the foot.
All you need to do is remove all the power steering parts. Once the hydraulic lines are disconnected you can work the steering back and forth lock-to-lock to expel the old ATF from the rack. Or you can plug the rack -- the little plastic plugs that come in new racks work fine, with a bit of silicone sealer. You have to clean the threaded apertures for the sealer to bite, though.
The power steering rack is lubricated internally, separate from the power steering fluid hydraulic assist mechanism. Eliminating the power steering system WILL NOT cause the power steering rack to wear out any faster than it would normally.
Nevertheless I think it's important to recognize that your rack is probably pretty worn at 200,000 miles. Wear is indicated by on-center play. There is no doubt that the clean way to do this job is to install the E30 manual steering rack. It's not hard to get -- it's just hard to get cheaply. The only source is BMW, part number 32 11 1 130 169. There may not be a core charge nowadays, since the cars are so mature. Last time I did it there was a core charge and BMW would not accept a power steering rack so I had to pay the charge.
