Updated shift adjustment

In what way is this part updated?
How is a 5.2 different from a 2.7? What are the advantages? Thanks

 

Looking at the 2.7 parts manual, it seems that the newer type offers easier adjustment. i.e. independent length and angle.

It looks like the 2.7 locking nuts (37&38) had to be adjusted simultaneously for rod length and rotation.

 

Correct.
I have been thinking to do this update on mine but then I looked at all the parts required and decided against it for now. It is basically easier to get a nice adjustment with the updated version.

 

That’s what I thought. But the shift rod is different. It has a updated part number. I assume as the length is changed with the updated shifter block.

One shift rod is 163518 and the new part for 5.2 motronic is 164392.

 

If you get the part 42, it seems quite simple to fabricate the disc for part 49 which should just follow the diameter of the circular section of the part 42. Then, machine the 3 slotted holes and weld-on a length of threaded rod. Does one side of the coupling have left thread?

 

One side of item 36 has a left-handed thread, and ... I cannot remember which side. If I had to guess, it's item 49 that is left handed thread. In a bind, I would modify the existing one to make it fit.

 

If the stud of the part 49 has left handed thread, it can be made from a longer bolt like, example: https://belmetric.com/m8-m14-coarse-hex-head-left-hand-reverse-thread-bolt/?sku=LB8X60F
