Steering box centering tool dimensions needed
« on: 03 February 2020, 05:09 PM »
Hi folks. There's a special tool (W116589062100) that makes centering the steering box a breeze. Looking at images of it, it can probably be made from a standard bolt, filed to shape. To me this looks like a standard 8x1.0mm, 13mm hex bolt with a 60* taper, but I'd rather know for sure. Does anyone have this tool, and could share the exact dimensions please? Thanks.

The best I could find so far is this:

1993 "Pearl Blue" W124 280TE
1979 "Icon Gold" W116 450SE (history, resto)

Lucas, these pictures may or may not be of any use to you, but maybe they will be.  You're correct on the thread pitch being 8x1.0.  I have no idea what the angle of the end of the cone is.....I can't find my protractor, and I'm too tired to try to remember how to figure it out in a trigonometric manner.  However, I have a feeling your guess of 60 degrees is probably accurate.  Even if not, as long as the end of the bolt cone seats in the divot of the power piston in the steering gear box it'll serve it's purpose of holding things steady while re-installing the gear box or steering shaft.
