I was reinstalling my UIM and the bolt (13-366A) would not tighten, I was using a torque wrench and it was set to ~17ft-lbs (FSM says 14-19ft-lbs if I remember correctly), but that doesn't mean it hadn't been over-torqued in the past. I've checked my normal sources, Mazdatrix and Atkins Rotary, and haven't had any success. I even went to my local Mazda dealership and they said the part is discontinued, which a web search of the part number seems to confirm.

Anyone else run into this before? Do I find a random bolt with the same dimensions?

I'm also not sure if I've completely trashed the threads in the LIM or not. So I may need some input on fixing that as well.

 

I've continued to do some research on this, and I think this bolt may be listed under a new part number (13-366B).

Anyone have experience with some of these web sites (e.g. BOLT | Genuine Mazda | L3K9-13-366B)?

EDIT: based on talking to shopmazdaparts.com the full part number for the bolt is actually; NF01-13-366.

 

Worst case scenario, if you HAVE stripped out the LIM, you can always drill it and helicoil it..

 

Believe the chrome bolt was discontinued and the later model greeny-black painted bolt was stocked....or it might be vice-versa....that was the case several years ago at any rate, the last time I bought one.

 

I've got a spare bolt, if needed.

Here is a link to the bolt, it does look like the one in your pictures.

 

Amayama.com is cheapest if you have the part#

 

Yep that bolt is fucked. Visibly twisted and stretched. Probably 1/4 of a turn from snapping.Doesnt take much to do it on such a long and skinny and soft bolt. I had mine go like that too, took it to a bolt shop and got a matching one- albeit without the flanged head.
