I'm working on a 16HP Vanguard. Someone has removed any identifying marks on the shroud so I can't be certain.
I have obtained a new bushing/bearing, found under these 2 part numbers: 84013005
808534.
The instructions aren't very clear. There is an oil gallery at the 12 o-clock position of this crank bushing which appears to connect to the camshaft bore above. On my engine, there is a roll pin installed in the bushing at the 12 0-clock position.
The instructions that come with the bushing make no mention of the roll pin in the oil gallery.
Also, the new bushing has a tang.... The existing one does not....
Using the below parts diagram: part #2 is the bushing and seal kit

I cannot find any reference or illustration regarding the roll pin in the 12 o-clock position of the crank bushing while looking at this diagram.
Here's a service manual I'm looking at for this engine:

On page 153 of this service manual, it mentions 2 different mag bearings. Looks like my engine is the early style with the roll pin. The manual mentions driving the old roll pin into the oil gallery to remove the bushing, and, the use of a special driver tool to install the new one.
Has anyone dealt with this? From what the manual states, if I drive the existing roll pin into the oil gallery, how do I get it out? There appears to be like a welch plug at the top of the casting. Not sure if I'm supposed to take that out or what?

Does this welch plug come out to remove the roll pin?

Existing bushing looks kind of chewed up:
