Assembling my engine. I noticed that the cam thrust bearing as a smaller tang. My case does not have the notch.
Since this is a smaller tang, designed a bit different. I am I supposed to tap it in place and let the action of bolting up the case crush it in place? I built a 1911 about 7 years ago, and I do not remember having issues like this. I am pretty sure I bought all my innards from Type4 store back then too. Clark  Notice no notch in the saddle..... ?  |

Tang is to prevent rotation of the bearing,there must be notch in the other case half otherwise that's the strangest case I have seen.

QUOTE(porschetub @ May 30 2020, 08:19 PM)  Tang is to prevent rotation of the bearing,there must be notch in the other case half otherwise that's the strangest case I have seen.  Close but no cigar. Even if it did fit, the last bearing has a tang and the saddle has no notch. Fuzzy pic but i tried to install the thrust bearing in the right half and the tang and the notch don’t line up. |
