Shift Coupler Adjustment - Is There A Trick To This

[Targa Me]

I resently replace my coupler bushing with Ed's bushing. Life was beautiful.

Then I pushed it a little further by installing a short shifter. The short shifter was merely changing out the bottom end of the shift lever. It was easy, heat up stock piece and remove, let cool and install new piece with the two piece bonding agent.

But now I can't seem to get my coupler adjusted correctly. I'm not new at this, I've done it before, but ever since I installed the short shifter I can't seem to find the correct adjustment.
All other shift bushings are fairly new.

Is there a trick I'm not aware of?
Help, please.

The only time I had much trouble when following the published procedures was the times when there was another bushing worn or broken in the system that was allowing mis-alignment.

I dont understand the SSk - you removed the bottom of the shift arm and put a new one on?

the factory SSk also changes the pivot point, if that is not changed maybe the shift tube is binding inside the tunnel???

I agree with Ed. That doesn't sound like the factory kit. The factory kit replaces the cage that the shifter pivots in. If you only changed the bottom portion of the lever, then it is likely that your shifter geometry isn't correct anymore.

What kit did you use?

[Targa Me]

It was not the factory kit.
The only piece I replaced was this.

Yeah, it doesn't work if you just switch out that piece. You can find the complete factory short shift kit here on Pelican. You need to swap back to your original base piece.

ok.
Well at least that explains my problem. So I'll move back a square, put the original piece back on for now and looks into the ssk.

Let us know if that solves the issue please

short shift kits will "show" any problems in the transmission worse than the regular shifter

search on short shift and read Grady's comments on why not to do it

the factory made the only short shift kit that is worth anything AFAIK

check all your bushings, incl. the one in the L shaped bracket

I just had the 915 repaired so I'm not suspecting any tranny problems. And like I said earlier, with Ed's bushing and the Stock shift lever life was good.

I'll do some homework on the SSK's.

I'll check-in later and give you guys an update.

[Targa Me]

ok, last night I replace the lower "thingy" with the stock one.
Shifting my 915 is beautiful again....(with a longer throw.)

Good to hear!

Targa Me:

If you install the SSK shift rod (or just the lower, as you did) but did not also change the saddle, your shift linkage will totally out of plane and likely bind.

If you measure the SSK shift rod from the "ball" end to the middle of the hole for the retaining pin, you'll see that dimension is longer than the measurement for a stock shift rod. If you install that into a stock shifter saddle (the steel rectangular piece in the shifter housing), the "ball" end of the SSK rod will sit lower in relation to the shifter housing, pushing down on the cup bushing and causing the shift rod in the tunnel to bind.

The saddle that should be installed with the SSK rod relocates the pivot point a little higher (toward the shifter knob) to make the leverage different (shorter throw) without changing how far down the "ball" end reaches into the shift rod cup.

Can't post pics at the moment, but check out the Seine Systems site for more details:

BTW, fresh coupler bushings and the Seine Systems kit transformed my 915.

Flat Six, thanks for the info.
I actually have a Seine System that is waiting to be installed.
