Default 968 Shift rod coupler bolt

Anyone have the details on the bolt that connects the shift rod at transaxle to shift lever. Cant find the part number and of course I don't have ht bolt. Here is a pic I lifted:

It's a pointed but not sure if it is drilled for safety wire.

Looks correct. I put a M8 x 1.25 in, not pointed. I thought I read it was wired somewhere. I will order another one

Thanks

it needs to be pointed, the tip is supposed to engage the divet. a nornal bolt will slip at the wrong time and leave you stuck on the side of the road. ask me how I know

it also is supposed to be safety wired, but blue loctite is fine.

the pointed part makes me wonder - the coupler, outside piece, slides over the shaft which is tapped M8 all the way through. I ran a wire through the M8 on the shifter shaft. Must mean the coupler has the taper point on the back side. If I loctite the M8 in the shift shaft it wont come out, maybe I will drill it and loctite, cant see what the taper point does.

thanks

No, the part is not tapped all the way through. The black shift shaft is tapped only on the driver side of the shaft, and the pointed bolt is meant to thread through that and have the tip engage the divot in the brass rod of the shifter mechanism attached to the trans. You could drill all the way through the entire assembly, black rod and brass rod and thread the entire thing and run a standard bolt with a nut on the other side, but I have never seen that done and anyway I'd think you'd run into clearance on the other side of the black shift shaft with it hitting against the trans case if a nut and protruding end of a bolt was there.

That picture doesn't show a 968 linkage, it's different. Look at some of the pics on this page:
https://rennlist.com/forums/944-turb...roject-10.html

I suspect that the bolt is different from the 944 part listed in this thread.

I pulled that number from the 968 PET but double check. I assume pointed from the picture

I happen to have that bolt out of my car at the moment, it's an M8x16 1.25 thread and it is pointed and drilled for a safety wire. I'd send a picture but my camera's broken and we've all seen bolts.

I can't remember what it was wired to. I hope it will be obvious when I re-install it.

Thanks Otto.

I see that in a picture also. Thanks. I think its M8 x 60mm with point. Cross drilled on hex for wire. I'm almost thinking I should just make my own. Does it look like a 90 or 120 degree point?

OK, double checked the length and I'll estimate the angle of the point at 45 degrees. The threaded part of the bolt is about 15.5mm (call it 16, not 60) the point is about 4mm between the tip and the first thread. Total length of the bolt is 20.5mm Confirm the thread pitch is 1.25.

I'd say you could make it with some patience. The head is drilled through the face of course.

This is from an '89 944S2 not a 968, but the linkage in your photo looks identical.

PS: Yellow zinc plated.

Otto Mechanic, look at the link I posted... the 968 linkage is different from the 944/951/S2 and so is the bolt

I would say get a few metric bolts at the hardware store, ( you can tread on a nut , then grind down a "point" on the bolt to fit that "Dimple", then use brake cleaner to clean the threads on the linkage, then Blue loc-tite on the bolt and be sure it is tight

Well, you're asking about #143? I can't see the difference between the stock linkage on mine and the one in that picture, except the one in the picture is cleaner

Really, it looks pretty much just like mine. I don't see a picture of the bolt. Were you looking at a different photo?

The part numbers are remarkably similar, the S2 PET lists the "intermediate shift lever" as 944 424 13 02, the 968 PET shows it as 944 424 13 01 (odd since the S2 came out before the 968). Honestly, they look the same to me.

Aren't you rebuilding these Michael? I saw something recently, instructions on how to re-build those intermediate linkages using thrust bearings? Wasn't that you?
