Title: It has begun...E36 rack conversion [PICS]
Post by: bmwman91 on October 26, 2007, 12:28:25 AM
I finally got the rack in the mail today.  $220 shipped from a place I found on http://www.car-part.com and it was in good shape.  105k miles on it, no leaks at all.  It is from a 1997 Z3 1.9L, which means it has the 2.7 turn gear ratio.  That will sure beat 4 turns on blown end seals!

Anyway, since I still have some special-order crap in the mail, I did some prep work today.

As you can see, it was a tad dirty, and had old tie rod assemblies.  I purchased new ones, as well as new boots (and just about everything you can imagine).  I rebuilt the PS pump 2 months ago, and also got a new resivoir and new hoses (minus the high-pressure line...no leaks in it and it is $240 f'n dollars).  I had wire-brushed it before the picture.

A little further apart.....

I decided that I wanted this thing CLEAN.  Despite the fact that it is already pretty weather-resistant, I opted to go overboard.  I began the prep-work.  Some MEK and brake cleaner came in handy for this.

I am addicted to the PVC / under-carriage paint stuff (No, I do not huff it).  It is something I strive to apply to anything that goes under the car, so long as the part does not get terribly hot.  This stuff has a pleasing texture to it as well (this is the stuff you repaint the rocker panels with).

And a little closer up...
Don't mind the masking-line around the input shaft area.  There is a rubber boot that will cover that.  I will also be repacking the rack teeth & shaft with fresh lithium grease.

I am not sure if I want to tackle the install this weekend or not.  I have to fly to Seattle on business from Sunday-Wednesday, leaving Friday evening & Saturday to do this.  I also have to get it aligned afterwards, which means I need to get it done by like 4PM Saturday, because this has to get me to work next Thursday.  While I am down there, the control arms are getting replaced as well (thinking of putting some nifty PVC paint on those as well).  I might have to hold off on this until I get back, although it will be even harder due to a weekend with GF & best friend from college.

I use some stuff by 3M, called Undercarriage Paint or something similar.  $8.99 for a large can.

Will you post pics from the installation process? I would love to see how it goes as I plan to do this soon myself.

The rack does look sweet after your paint job.

Well tittysprinkles, the special parts are delayed a few days.  Looks like I will not get to this until I get back from my business trip.  If I can take this coming Friday off, I will do it then.  Otherwise, my weekend is occupied with the GF and an old friend and it will have to wait until the following weekend.

LOL, nice.

I have a question for anyone who may have done this, regarding the tie-rod lock plates.  When I took the old tie rods off of the rack, there were none.  RealOEM does not list any in the bill of materials either for the rack I have.  The E36 M3 rack has them listed.  Does the Z3 rack not use any?  It seems a little dangerous that way...

Well, I purchased the ones for the E36 rack back when I was getting everything.  When I took the used unit apart, there was nothing in there resembling them.  The ones I have are like big washers with a little tab and a semi-circle welded on.  You have any pics of what I am supposed do to with these?

You know, they may be the locks.

Again, for reference, there are no lock plates listed in the BOM on RealOEM for this rack.  The other E36 cars have them listed, but not the 1.9L Z3.  I have a hard time believing that there is no securing plate when every other BMW has them!

As for the paint, any old car parts store should have it.  Just look for the rubberized undercoat stuff.

As for the lock plates, Stuck cleared that up.  Apparently a number of racks don't use them...Loctite is the solution in this case.

The E36 rack and short shifter are the two most enjoyable mods I have done so far. They make the car feel a lot newer and much better. The high pressure line is pricey. I got one made at a hydraulic hose shop for $60. They soldered the BMW banjo fitting to their new crimp fittings and hose.

Is it possible to do that the rack-mod to a non-power steering car (e30 318is)?

No reason you could not have a custom line made to just loop from one outlet to the other. Would work fine this way.

Non power steering cars require a change to the steering shaft coupler. There is a write up on R3V about it.

It would be nice to have photos or a drawing of the modification of plate #6.  I took shaft part #1 out and then removed plate #6. I cut it so that the lower part of the opening for boot #4 was rotated clockwise (looking from the front of the car). I made an aluminum patch for the open area that was left and pop riveted it to #6. It's a lot easier with #6 out of the car. The angle of the pinion housing is different on the newer racks and they move the lower end of shaft #1 toward the center of the car.
