The end of the block sits just below the housing face. I measured 0.1 mm.

Next, I measured the recess in the cover plate, 1.7 mm.

Then I measured the thickness of the original shim, and the gasket.

Here's the math. The total gap, including the gasket, is 2.1 mm. The designed gap is 0.2 mm. Can you spot my math error? The desired shim should be 1.9 mm! But the original shim is 1.85 mm, so all is well.

This is awesome, I will be doing this to my rack soon. Thanks for the picture of the seal as finding a replacement was one of my concerns. (IMG:style_emoticons/default/smile.gif)

Steering rack, part 2.

I started with the eye-bolt build kit.

No instructions, so I made up my own.

Here's the bushing and eye-bolt on the press, with plenty of liquid soap. Centering is important.

After the first attempt to press in the bushing. Watch out for pinching the rubber edge between the piston and the eye-bolt. Ask me how I know.

Another squeeze, just to the limit of pinching.

With the pressure released, the bushing rebounded a bit.

I then pressed into a 27mm socket, matching the outer rim of the eye bolt.

That was enough to get just a bit of the bushing edge out the other side of the eye bolt.

I then used my blunt ex-screw driver pry tool to ease the edge out all around.

Then I pressed in the metal center bushing. Again, lots of soap.

And then a smaller socket to press against the rubber bushing.

Ready for the final assembly. The specs come from the factory shop manual, and specify the lateral dimensions (278 mm left and right from center) and the angle of the eye bolts (9 degrees down to the rear).
