Default Pincor / Gen-E-Motor Con Rod Bearings

Posted elsewhere on the 'Stak is a thread about a couple of Pincor Army Radio gensets:

I picked up an operators manual for the Army genny from a friend, and now also have a Pincor manual for the A, AL, AG, ALA, ALB and AM engines.


Does the connecting rod have any bearing material in the big-end, or does it run direct on the crankshaft. Both engines look very similar, although of different part numbers. The Civilian engine has an Alloy rod, I don't know what material the Army genny engine has for the rod.

Any help/info would be appreciated.

All the civilian Pincor "A" series engines I have seen have an aluminum rod with no bearing inserts.
The gen sets shown in that other thread have Pincor generator heads, but the engines are Johnson Iron Horse. It has been quite a while since I've been inside one of those Iron Horse engines and I just don't remember if they used inserts or not...
The picture below is a civilian Pincor Model ALA.
