With the trans in neutral, attach a bungee from the shift lever to the passenger side door handle while the adjustment bolt is loose. Rotate the splined shaft to the right as far as it will go, then tighten the bolt.

Damn I have been screwing around with "one spline at a time" method for all these years.

Now you tell us a secret.

Would this work for a Rennshifter as we'll ?

In concept, yes.
However, the centering springs probably make it difficult.

A bit of a ressurection here, but I'm having some 'challenges' with aligning my shifter after a bushing change (tail shifter). Presumably this method is common to tail and side shifters... But my question is if the splined shaft referenced is the forward shaft, connected to the shifter, or the rear shaft to the trans... Logic tells me it's the latter.

Thanks.

It's the splined end, at the shifter lever end,. Does take a bit of work to find the sweet spot.

Excellent, thanks! That will hopefully be my Sunday project.

Another trick I have learned (even if using Racer Chris's method):

Paint some white out across the splines at the adjustment point and then mark both sides of the interface with a mechanical pencil or other accurate marking tool - BEFORE you adjust it.

Probably 90% of us will adjust it the wrong way the first 5 times and you want to be able to at least put it back where it was.

So I'm now back to a point where I have first through 4th pretty cleanly...but I can't get to 5th. Based on the cutout in the plate within the shifter housing, am I correct to say that 5th is actually slightly further over than 4th? If that's the case I suspect I just need to get a LITTLE more travel to the right and I'll be set.

Nope. The 4-5, 2-3 throws on a properly adjusted box are equidistant. If you are not getting 5 that is odd. It should be the same amount back as 3 and 1.

Where is the adjustment screw? I think R & 1st are way too close to the drivers seat. I'm thinking this will fix it.

On a side shift, the adjustment is made directly behind the shifter.
On a tail shift, it is through the access hole right in front of the firewall bushing.
You have to loosen the bolt (IIRC 13mm) and rotate the shaft one spline at a time.

Mark both pieces with a fine tip magic marker
put two or three lines across the splines to reference for depth and a single line in one spline and onto the adjoining piece for rotation

So mine is a tailshifter and I just finished replacing all of the bushings in the shifter and the linkage. That took out a lot of slop.

I used this method above to adjust the shifter afterwards and it did improve getting it into first but then noticed that it made it easier to nick reverse when shifting into second, hence my question....

If R and 1st are in the same plane and I have to pull the shifter over to the left against the spring-loaded plate underneath to get 1st, then shouldn't the shift lever move far enough to the right as I shift from 1st to 2nd to be out of the same R-1st plane so that I don't nick reverse? When shifting into 2nd I have released all "left ward" pressure against the spring.

What am I missing? Anything else I can adjust?

Sounds like you may need to adjust the lever over to the right just a touch more. Or maybe to the left a touch more? But there are many reasons that we tell people to momentarily pause in between gears when shifting a 914; allowing the lever to fall into the correct plane is only one of them.

I use the put it wrong method, and then estimating how much you need to correct it, pull it out, curse, scream, and rip up your hands, and then finally get it in. Results may vary.

For Rennshift, multiply the frustration times 4.
