Question 911 shift **** removal assistance

I am going to replace my shift **** on my 88 911 and upon test removing the ****, it doesn't appear to be screwed on. How are these things removed from the lever? I don't want to ruin anything while removing.

Thanks!!!

My goof...just realized my link won't work. Basic technique is to get an open end wrench that fits the gearshift shaft...place this under the bottom of the ****, hit the wrench upward with a hammer. This is the technique for ***** put on with a crush sleeve. You'll need to buy a new crush sleeve when replacing the ****...unless you use an aftermarket **** that fastens with a set screw.

Its held on by an allen head fastener that bolts down vertically through the top of the **** and into the threaded shaft, and is accessed by removing the plastic shift pattern cap on the ****. There is also no crush sleeve, unlike on the earlier 915 shaft.

Good luck,

If, by chance, yours doesn't have the allen screw...I just did my 80 with the open wrench (fit it close to the shaft size) and a rubber hammer. Word of caution, wear very thick gloves on the hand holding the wrench...and don't have your head in the line of sight with the **** when it "flies at a great speed" off the shaft!

I will pop the cap off and check for an allen screw before trying the wrench, hammer, shift **** in the head trick. Looks like I can't get a leather universal **** with a threaded end based on this info. What are my options for a replacement?

Thanks!!!

If your '88 has the stock shift ****, then you will certainly find an allen head bolt that goes down through the **** and the shaft. Pry up the edge of the plastic shift pattern insert and you'll see it.

Just to clarify, the **** itself is not threaded, and does not screw onto the shaft. Instead, the **** has a semi-circular, "D" shaped hole that mates with the "D" shaped tip of the shaft. This allows the **** to fit only one way and not rotate. The allen bolt goes straight through the non-threaded **** and into the threaded inner diameter of the shaft.

Most, if not all, aftermarket ***** just mount with a horizontal set screw through their base against the outer diameter of the shaft. Not ideal, IMO.

If you're interested, replacement leather factory ***** and center caps are available from any dealer, as well as many aftermarket vendors such as <a href="http://www.pelicanparts.com/catalog/shopcart/911M/por_911M_pedals_main.htm" target="_blank">here</a> at Pelican.

Good luck, and put that hammer away...

Thanks Tim...do you know the model year that Porsche changed to the allen head bolt and dropped the crush sleeve?

With the introduction of the G50 in '87.

cyprusx, I went to a local leather shop and bought some small pieces of thin leather (in the clor I needed) and used the leather that was worn as a template and made a new cover. I made it a shade tight and just prior to sliding it over the ****, i put it in water to allow it to stretch. When it dried on the **** it fit like a glove. If you try this, be sure to leave extra leather at the top and bottom so there will be enough left over to tuck under at each end. I have several ***** guys have given me when they bought new ones, so I have some i recovered in case my goes south again. LOL.

reminds me of a funny aside...did my dad make the first leather shift ****? Using the "shrink the leather" technique above, he placed the ******** sack of a deer he'd taken over the stock **** of his '50 Ford pickup. He told me he started doing this in the 1920's...
