Connecting Rod Journal Diameter

[Price]

I am trying to decide if I have standard rod bearings in my 170 engine. It's a 2R5 truck.

I looked in the shop manual and wasn't able to find a spec. My crankshaft diameter is 1.812. The bearing caps have a zero stamped on them.

Any information or help is appreciated.

Thanks

According to my "Motors Truck repair manual" the con-rod diameter is 1.81175-1.81275. The mains' diameter is 2.437-2.4375. Neal
