Can you get a picture of the type you want, with measurement (I assume the missing one is similar to the others that you do have)? I may have one knocking around somewhere.

threaded bar?
are you trying to replace a missing "stud" with a nut and bolt?
or, a missing bolt, with a bolt of equal length/threadpitch and tensile strength?

Sorry guys I wasn't very clear with my description. Its one of the four threaded bars that attach the gearbox to the engine. Picture attached. If you have one that would be great.

I only have machine screws (nuts and bolts) on mine. In fact there is no sign of any thread on the engine block for a stud (what you are calling a threaded bar) to screw into.

New_Alfa,

try germany

Alfa-Service

notice the 2 different thread pitches (one side should be 8x1,0mm / the other 8x1,25mm)

if the link doesn't direct you straight to item, then it is their part # 03 143 0 0

hope it helps

EDIT: actually Classic Alfa has them as well (just noticed), their part number EN135

I replaced mine with regular grade 8.8 bolts (with appropriate shank)- makes it much easier to get the gearbox in and out. Should I have used a fancier grade bolt?

that'll be ok, methinks...

Quick update. I got the threaded bar from Germsny and fitted it. Putting the gearbox back on today. Question are there any torque settings to tighten the engine and gearbox together or is it just a tighten till you can't! I can't see any reference to this in the manual or on the sites!

I couldn't find torque specs for bellhousing>engine in my S4 manual either

I guess that is because you'd be hard pressed to get a wrench in there, unless the engine and box were out of the car.
But, I wouldn't go mad tight on those.......nice n' snug with a normal ratchet with a drop of loctite maybe for good measure (unless the nuts are plastic lined locknuts;)


a suggestion of ca 15 ft/lbs here
