This has been discussed many times before and there is other thread about Devek lever lenght active right now. Desided to start new one anyway as I don't remember comparison pics like these being up yet. Red short versions are from 928 International. Don't know if Devek's is same or not.

From left to right:
'78 4.5L factory lever what has been shortened by about 35mm
'78-'84 928intl short shift lever
'92 GTS factory lever
'85-'95 928intl short shift lever

Measurements:
A = From center of lower pipe to the top notch (this might be few mm off but if wrong all are same mm wrong)
B = From lower pipe center to upper pipe center
C = Pipe inside diameter (within 0.1mm same on all four)
D = Pipe lenght (all exact same)





'87 S4 measurements on the way within next week or two unless someone already has them on hand?

So are you saying that the '85-95 shifter from 928 int'l is the same as a sawed down '78 shifter?

Vilhuer

It seems they are close and old version could be used with little modification.

erkka, you are neglecting the weight saving..

I just put a Devek unit in mine on Sunday and what a difference. Feels good looks much better that the stock look.

I had one installed and I was told that the OEM springs cannot be reused and that there are no new springs for installation with short shifter (928 Specialist and 928 International are the same part, I belive Devek's is the same). Is that true? I have serious problems downshifting, specially from 4th to 3rd. If I want to accelerate in 3rd, It will not dows-shift until engine RPM drops sufficiently. Is that normal with short shifter?

Green Goblin

Didnt put the springs back in mine the instuctions didnt call for that. Did you clean and lube the shafts as specified. The downshifting would be more of a clutch problem or syncros. Did you replace the four bushings.
Best of luck Voytek

Thanks GG,
I did not replace those four P/N 999 924 002 40 bushings, or slide bearings, and I am not sure about cleaning the shaft. My OEM lever was downshifting from 4th to 3rd like a charm - with one finger and no delay (with all new clutch, 66K transmission, and Mobil1 75W-90 oil). It was really smooth - no resistance when pushing from 4th into the 3rd and immediate acceleration! Now I have to struggle with short level for a few secondes before engine RPM drops enough allowing level to eventually snap in the 3rd. Can You, or anyone who insrtalled it, go from 4th to 3rd with no delay?

Voytek,
Even without bushings, the shifter will still work - and looking at Erkkas pics, you can see why the springs cannot go back in with the after market units: their shaft is centered on the pivot 'barrels', unlike the OEM shifters.
Is it possible you have the early short shifter (49mm centers) installed rather than the correct 35mm center S4 unit? Easy to check, and if that is OK .... then with a downshifting problem ( that taxes the syncros), you might want to check the stroke of the slave cylinder, or bleed it to assure complete disengagement.
Just a thought to check elsewhere, as the shifter linkage is so dead simple.

i have the short shifter in my 88 and no probs going from 4-3. very nice modification.

Green Goblin

Mine shifts smooth also, although it is quite a bit firm or stiffer.

Morphing a 1980 Broomhandle into a Short Throw Short Shifter

I did this for my 86'. The benefit of doing this mod over purchasing a pre-made is that you can cut the length to your comfort and still maintain a "short throw". Mine works great.

Looking back all the threads found through JKelly's link we would need to get S4 and Devek (do they have one or two versions?) levers measured to have data on all variations. Or is there more factory versions than '78-84, '85-89 and '88-95 (on '88 in CS and SE)? All '78-84 have that horribly long lever or is there semi short factory version for '8x-84?

PS. There was some talk on one of the threads about gear lever wanting to stay between 4 and 5 when in neutral. I have since learned this is design issue and all gearboxes up to end of '86 model year should have lever in 4/5 slot. One spring was changed in S4 box to make it stay between 2/3.

JKelly

In the first picture, I believe the '78-'84 928intl short shift lever (second from the left) would have a real difficult time fitting in an 85+ model. The distance between the shift linkage bushings is too great; therefore, it is made for the 78'-84'. The 78-84 factory lever (broomhandle), barely fit on my linkage and I had to grind the very bottom of the shifter more round, like the aftermarket shifters are. The squareness of the bottom of the shifter would catch on the thick sound deadening material in there and tear it up.

From left to right '87 S4, '92 GTS and '85-95 928intl short shifter






S4 lever measurements are:
A = 220mm (20mm longer than GTS)
B = 25mm (same as GTS)
C = 11.4mm (same as others)
D = 28.3mm (same as all others)

Surprising that B is same for S4 and GTS. Is GT lever also 25mm? If so, it's possible to make GT out of S4 quite easily.
