Hey guys
Im kinda in a pickle here
Im doing a diy custom shorten shifter (quick shifter)
I have followed Cummins diy pdf: http://www.aussiemagna.com/forums/showpost.php?p=234827&postcount=28
How ever 1st gens use a slightly different system

Heres a pic from the tp factory manual
Now say if I was following Cummins procedures and adding an extra 30mm to the lower parts of the shifter

So I add 30mm to *1*, now this will reduce the actual ‘length’ of the stick from UP to DOWN and visa versa

Now this is where im not 100% on
So to reduce actual ‘length’ of LEFT to RIGHT, do I need to just add another 30mm to *4* (pivot lever) just before where it actually pivots so the top ˝


Now if im right ^^ would this mean I wont need to make standoffs as Cummins calls them (basically raisers) because by adding another 30mm to the top 1/2 of the pivot lever *4* this will raise the lower ˝ of the stick for UP and DOWN to meet the selector cables??


Note *4* is *3* on lower picture

You need to work the on the arm coming off (3 in the first pic) to reduce the left/right throw.

By shaping it more aggressively you can acheive this. I need to get more batteries for my camera and then I'll take photos of mine so you can see what I mean.

But that is what you need to muck around with.

You are right in extending the bottom of the shift lever(1st pic part 1) to reduce the front to back shift(although you may need to relocate the stop (1st pic part 2)).
The problem is then with the height and the fact that the shift lever is held by the pivot lever. To get the right height you would need to extend the top of the pivot lever by the same length you extended the shift lever, this however increases the side to side through considerably.
To fix this (and make the through shorter side to side) you may be able to extend the arm of the selector lever that connects to the selector cable, this will depend on cable locations and clearance.

OR…much easier… you could extend the bracket where the pivot lever bolts-in/pivots by the 30mm, not extend the top of the pivot lever but instead lengthen the bottom of it. This will both fix the height issue and also reduce the side to side through. Just remember that there is a lot of force on that pivot lever!

In short, it is not as easy to do as the 3rd gen shifter, usually short shifter of this style involve completely redesigned selector and pivot levers to overcome these problems or use transmission mounted levers that reduce the through required on the cables at the transmission case.

Good luck with it, make sure u take pics as well!

ahh yes come to think of it your right because if i did what i said to the pivot lever ^^^ this would fix the hight problem but will do a reverse effect on the side to side
but then the problem i have by extending the lower 1/2 of the pivot lever is the mount (where it pivits) for the level will have to be raised hmm this might be tricky

but yeh pics would be good KB sounds like the gen2s are similar then?

It looks almost exactly the same.

As soon as I get some batteries (Will try to get some on sat) I'll take some pics.
