Suspension markings Options

[wonkipop]

took a look at my 01/74, got curious.

all i can still see is what i believe are the traces of a K in a circle on rhs.
overshot with undercoating when car was new.
whatever is there on lhs has undercoating over it and is invisible.

when i take wheels off next will look for anything else.
but a wipe down of arm further along would appear to indicate nothing else is there on either side.

example from files on ECA/B engine research.
06/74 1.8
1 in square on left. K in circle on right. no other markings.

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.

another example from L Jet research.

05/74 1.8.
lhs traces of square with 1 (?), rhs square with 1




of interest - driveshaft has a number on it. 9 or 6 ?
