Thanks Diecast for your message. You might be interested to know that the Cam Gears drawings (at least early ones) are stamped "Steerings Pty Ltd" of Gardeners Rd Mascot. Evidently they must have moved as business picked up in the 60s.
I've written up an article on steering rack reconditioning process which is now available on my web page under "Articles" at
http://www.leylandaustralia.com.au. I hope interested readers will find this useful, and would be happy to discuss any aspect of it.
I've also read the article written by Chris Katiskas which is referred to in another recent post from the reader in Guam who was wondering if he should recondition his own rack. Now, Katsakis is a knowledgable guy, but this article contains several errors which could be potentially dangerous and I feel I should mention them here in case someone follows his advice. In this article, there is an apparent ignorance of the presence of a pin which does through the lock ring and ball housing in to the rack shaft. Just going on what he shows, Katiskas has just sheared off the pin completely while undoing the ball housing apparently believing that the only connection between the lockring and housing are the stakes on the surface between them. But these stakes are to stake the pin so that it doesn't fall out. You can see the sheared off pin in one of his photos, and then a semi-circular hole through the thickess of the ball housing in another photo which goes unremarked. In later reassembly, the need to re-pin the two parts to the rack is not mentioned. As well, the procedure of setting the ball housing preload is totally wrong. Sorry Chris, but you must have been having a bad day on that one.
