Well folks, I thought I was being careful taking my 1948 single lever trans apart, but I did make a boo-boo. I don't know how to position the inner shift shaft lever, in relation to the outer shift shaft lever. (This is the rod activated lever - not the cable one.)
Page 8-10 of the manual says the inner lever should be straight up, but says nothing about where the outer lever should be. The inner lever slides onto the splined shaft. There is no key to determine a set assembly position so the inner lever can go on in many positions. This is non-adjustable after the transmission is in the car, so I need to get it right on assembly.
I think the inner shaft should point straight up and the outer shaft should point to about 7 or 8 o'clock.
Can anyone advise me on this please?
That is correct. The lever fits on a spline, and can be either slightly forward or rearward, depending on what spline you fit it on. and it should be forward, to give correct movement form the linkage.

Mike, before you install the actual shift arm, line up the inside lever parallel and the outside lever parallel, then check to see what location the arm is clocked. As Geoff describes, one position is slightly off and the opposite position is equal outside/inside.
So, are you guys saying that the two levers should be one spline away from parallel? They are presently inner lever straight up at 12:00, and outer lever slightly forward at 7:00 (as viewed from the left side.) Does this sound OK? This is one spline away from parallel.
Thanks for your advice Geoff and Doug - much appreciated
Remove the inner lever , turn the shaft 180 degrees, now re-install the inner lever. This is without the outside lever installed. One position is slightly off, and the other position is straight. With that said, now install the outside lever on, and decide what fits your linkage best. I have found the best adjustment is obtained when we use the straight inside and straight outside combination is used. The outside lever has an offset built into it. The linkage is adjustable, but depends on what you are installing it in. Since yours is a '48, it could have 2 different styles of linkage.
Will do!
Thanks again Doug
Well, Mike, I did the same, resulting in the outside arm being in an excessively rearward position. Kicked myself all over the garage. Once I got over that, I realized the shift rod coming off it need only be extended by about 1.5". So, I cut off a bolt of sufficient length, welded it on, chased the threads and installed. Caution on the motion of the shift rod, it comes very close to the starter HOT lug, so a slight bend of the rod is in order.
Attached shows a the bolt used. If your situation is that you installed yours such that it is one spline too short, the opposite will be true: you may need to shorten the rod. If you look closely at the second photo, you'll see that the single shift rod is rearward. The photo was taken just after installation into the car (50 Commodore 6).
Hope this helps,
Pat
Hello Pat,
I'm curious to see your photos. Could you resend please?
Just edited this post using Chrome instead of Explorer AND further reducing the size of the photos. I hope these images have sufficient resolution to convey my meaning.
Mike,
Yeah. I noticed an error after submitting the post stating the photos could not be uploaded due to size (they are actually small in memory size, not sure what the issue is).
Pat
