Carrier bearing mounting bolts, cotter pin bolts?
Just curious if the carrier bearing mounting bolts are supposed to be cotter pin bolts. I don't see a good reason for cotter pin bolts.
As I found them, there was a bolt and washer below, and a lock washer and nut on top. There were no cotter pins, though one bolt had what was left of one. Thank you

Fine thread too, right? They always have those but I have never seen cotter pins in the holes...

Welcome back, Kotter! Couldn't help myself. Nope, no Cotter pins required in that application. Looks like someone went in and did a little dirty work at some point.

 .......... Judging by Randy & your responses, sounds like it's a normal application, less the cotter pins. Yeah, someone busted a cotter pin in one, left it in there. I didn't even notice until I cleaned it. Thanks for the responses.

Re: Carrier bearing mounting bolts, cotter pin bolts?
Those are the right bolts and nuts. I guess maybe they had voter pin sin them from the factory, I just don't ever remember seeing them.
I lost one of those oddball nuts a couple weeks ago...I know the direction it went so I guess it will turn up. |

Re: Carrier bearing mounting bolts, cotter pin bolts?
I dont think a cotter pin would be as effective as a lock washer in that application. I have had several of these trucks and never observed a hole in the bolt for a cotter pin used in that location. so dont read too much or over analyse the hole deal.
