Malbaby Posted April 21 Report Share Posted April 21 (edited) Hi Guys.. My project car...TR4A with 6 cyl TR engine. I am confident that I have the rack in the "factory" position, thanks to very helpful forum members that provided the measurements. Currently the "Certifying Automotive Engineer" that I have to use in order to eventually have the car registered requires documentary proof of what I have done is the correct factory position.. I have seen the factory chassis measurements diagram, but the rack location/mounting plate face is not clearly seen.....Usually in relation to the main front cross member. Are there any "factory" or workshop manuals that give the precise location. Or, is there anyone that can take some pics together with ruler/tape measurements on their TR5/6.

Malbaby Posted April 22 Author Report Share Posted April 22 (edited) Can anyone interpret the height measurement of the steering rack mount plates in relation to another part of the chassis from the workshop manual, pictured above. Edited April 23 by Malbaby Quote Link to post Share on other sites

jerrytr5 Posted April 24 Report Share Posted April 24 Quite difficult to do on a running car, however using the main chassis crossmember as a datum point I get the following: Rack mounting plate to bottom of cross member 173mm. Using straight edge clamped to cross member. Rear of rack mounting plate to front of cross member 85mm. Using plumb line. Not too accurate so +/- 3mm I would guess.

Z320 Posted April 25 Report Share Posted April 25 (edited) Hi Melcolm, at Stuttgart there is a classic car fair, we (TR IG Südwest e. v.) have a 250 and s 6 on our stand. Perhaps I can measure for you at Saturday. What I noticed from remembering my 4A crossmember above the rack: it is more solid than what I found in the 250?
