Rear arm removal and refitting

Post by Vanny » Thu Feb 01, 2007 10:23 pm

Citroen Workshop manual xb 433-2 which deals with the replacement of rear arm bushes and the corect method for reshimming can now be found in the downloads section of the BX Project

And also at the following direct link

http://www.bxproject...SNIP.../XB422-3RearArmBearing.pdf

This follows on from a sub discussion in toms post about TZD Restoration in the 'Chat' area

Thanks Vanny, the mystery unfolds...

It looks like the tool is actually used to measure the distance between the outer faces of the mounted bushes so that shims can be used to adjust this width to ensure that the metal spacer length is just shorter than the bush face to face distance, and so does not protrude beyond the bush faces. This makes sense now. The specified torque on the 24mm nut of 13 kgf m is converted to thrust and transmitted through the subframe to the thrust bushes to establish the preload on the bearings. If the spacer protruded beyond the outer surface of the bushes, it would but against the subframe and interfere with the transmission of this thrust. Sufficient shims are added to ensure that the spacer is just shorter than the bush face distance by a fraction of a millimeter.

A picture paints a thousand words. Thanks again Vanny.

An appropriate moment for the reference to pictures and a thousand words methinks.
this might be a signature

The screw trhust must be about 90,000 lbs for a torque of 13 kgf m and a 2mm thread.

I've never been much good at small torque......

Some say that the car is a phallic symbol. I don't know what they're talking about.

As far as I'm concerned, my car is red, always starts first time, takes longer to get up than it used to but will stay up all day if need be, not the fastest but has plenty of power when it's needed, and is responsive in the right hands with loads of thrust at critical moments.

What on earth is phallic about that?

Never thought of the BX as a phallic symbol - but an E type in the awful heather (pinkish) - well!
