Suspension markings Options

[scotty b]

I remember this being brought up before, possibly by myself, but I can't find any trace of it so I thought I would atart a new thead specifically dedicated to suspensions and in this case factory makings on them. These pics are from Jim McCloeds 73. All markings are on the rear trailing arms and I could find no evidence of anything onthe front suspension. Notice there is one brushed on and also one stamped mark on each side. (IMG:style_emoticons/default/idea.gif)

I am revising this post because i have looked over the photos on this thread and noticed something about the painted numbers and the stamps in relation to their orientation on the trailing arms.

1.

the hand painted numbers on the left hand trailing arm appear upside down.
the hand painted painted numbers on the right hand side appear right side up.

examples from page 1 of this thread.

rhs top. lhs bottom image.



when you look close even the K stamps seem to have the same bias.


i noticed this image from page 1 also.
it suggested set of trailing arms set up on a bench in this orientation.




when you arrange them like this the upside down and right way around markings make sense. as if they have been in a test jig or check measuring jig and then marked up as a pair.







i think prior to reaching the assembly line these trailing arms get checked to see if they are within tolerance and marked up accordingly. they are put in some kind of test or check jig which is horizontal with the trailing arm bearing shaft pointing up. the resulats are painted on and marked up. probably to assist with the final wheel alignment likley done right at the end of the assembly line.

i'm not sure exactly what the numbers mean as they don't make a lot of sense to me in terms of alignment values.

but i think the K means korrekt. (correct) the circle means zero or nought.
correct with 0 compensation required.
the other numbers and maybe the square with a 1 in it are guidance to compensate for a trailing arm that is not quite true or straight but is still within acceptable tolerance.

????????????

for sure i think these things were marked up well before they got to the final installation jig on the production line where they would have arrived as a completed component with brake lines, bearings, hub, brake disc and caliper etc.

the way those markings are upside down and right way up side to side of car is very suggestive to me that the trailing arms are marked up elsewhere and prior to final assembly and marked up as a pair.
