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..... ? |

A bit late to the party, I came upon this a few days ago. The tang for this thrush bearing is smaller than the rest of the cam bearings. My gut is telling me to cut a tiny notch in the case, Dremel.
And why the single thrust bearing?? Another victim of a bean counter? |

And why the single thrust bearing?? Another victim of a bean counter? All VW Type 1 engines came from the factory with a single thrust bearing – the 'hot tip' when building a performance engine was to use two sets of cam bearings and steal the thrust bearing from the second set, filing off the tang so it would fit the case. Nowadays you can buy double-thrust bearing sets with a tang on just one half. |
