Shift knob won't stay on, What's the fix? Options

[drmitch]

Hi all,

The new 914 went into the shop for a couple of things. One thing they did was take out the atrocious short shifter that a PO had installed and replaced it with factory. It's a huge improvement. HOWEVER...while the shift knob on the short shifter seemed to be solidly attached for eternity, the knob on this replacement came off in my hand before I got out of the parking lot.

I circled back and a tech wrapped some black electrical tape around the shaft and tried several times to get the knob to grip. He did so, but told me it probably wouldn't last and what I need is a knob with a set screw.

Since these didn't come with a set screw, and since the previous knob didn't have this problem, and since I just dropped $500 at the shop, I think it's reasonable to expect the new knob to be as good as the old. The new knob came off in my hand twice on the drive home. I've sent an email to the shop owner asking for a solution.

What say you all? Yes, there is a crush sleeve up in the knob. If the solution is to put a new one in there, please tell me how to get this one out. If the solution is epoxy, I'll do it. If the solution is a knob with a set screw, please point me towards a source. I couldn't find one yesterday online.

THANKS!

Resurrecting this thread. I've not tried a new crush sleeve yet, but I've done the tap with a rubber mallet thing twice. It's nice and tight after that...for a few miles. Then it's rotating. Then it's slipping off. Maybe I'll order a crush sleeve, though it was a new one when this was put one at the shop a couple of weeks ago. Otherwise, do any of you know of a knob that would have the right look but has a set screw? It's that or the epoxy suggestion. I'm tired off wrestling with this thing and I don't want to keep beating on it.
