removing 308 GT4 gear shift knob

Maybe you don't have a stock/factory original knob on there now. It wouldn't have an allen screw opening. If you have an allen screw, you need to back it off or you might wreck the threads on the shifter shaft. The factory knob threads on the shaft directly, with the 17mm nut to allow you to fix its position so that the engraved gear shift pattern is straight.

 

Rick,

On the bottom of my shift knob, there is a nut that you unscrew to loosen the shift knob. Once that nut is loosened, you can remove the shift knob.

For the dead pedal, I did remove the rubber underneath. Note: I noticed that the dead pedal for the 308 GTB/S cars is different from the GT4 deadpedal. I purchased mine from Ultimate pedals, and he custom made a dead pedal for me.

Here is a link to a thread which contains a photo/description of my setup:

Hope this helps.

Rickjaffe, as suggested above, sounds like you have a non-standard knob mounted there. Possibly a Momo or similar knob that fixes to the shaft via small allen headed bolts rathe than threadin down the shaft thread with the 17mm lock nut. If you can get the old knob off you will find that the factory knob will thread on the shaft thread just fine - be sure to thread the lock nut on first so you can tighten this up against the knob and thereby lock the knob in place on the shaft.

 

Does anyone have a spare stock locknut to sell? The one on my GT4 is long gone, and a standard 17mm nut looks stupid there. Thanks for any leads.

I believe Paul Hill (FChat sponsor) has them available
LN01 - Locknut for gear knob - £3.50 each
http://www.customferrariparts.com/ferrari-shiftknobs.htm
Daniel at www.RicambiAmerica.com may have them also since he carries Paul's stuff.

 

Check a hardware store, or industrial supply house like Grainger's.

Seems to me I got them at one of those places. Probably in the SS section.

 

It looks like a funky nut that has two slots to grip it instead of the usual hex pattern. I would imagine that the knob can be simply unscrewed. The nut is just tightened against the knob to hold it in the right orientation. You ought to be able to unscrew the knob, then the nut will unscrew easily as well and you cna replace it with a normal nut, which is just a thin 17mm nut.

Where is this allen bolt you were talking about??

There were two disigns of nuts securing the gear lever knob - early cars had a larger locking ring with two slots in it for removal and the later cars had a 17mm hexagonal domed nut.

If you damage your locknut the early type #103312 cost £8.25 (GBP) and the later type cost £1.10 (GBP) plus postage, but you should be able to remove without damaging

You can just use the tip of a large screwdriver turned sideways.

 

Just do as Mike says above, shouldn't be that tight

 

I have two-slot nut on my Dino. Never could find a spanner to fit so just grabbed it with a pair of Vise Grips adjusted to leave groves in line with slots. Clamped and unscrewed 1/8 turn. Everything came loose. Removed ball with my fingers. Looked at nut and there was hardly a scratch. I use same tool, same position, to put nut back and no one knows.

You do have to loosen nut to get ball off without ruining ball. There are all kinds of ways to replace/repair nut once it is loose. You probably will not have to.

Go for it!

Where can I get some of those 5-10 horsepower nuts? I'll use them on everything.
Can you say Enzo/GT4?
