Hello DonW here's the torque specs you need....

Hi DonW,
I own a 1966 Oliver 1850 with the Perkins diesel, however, I have a complete original shop/service manual (NOT the I.T. or after market manual, but the "real McCoy" that Oliver mechanics used) for the 1850 diesel and gas, and 1950T, so here are the specs you were needing. In fact here is a list of most torque values for your engine:

Cylinder head cap screws 129-133 *All of these are foot pounds
Cylinder head oil cap screw 129-133
Main bearing cap screws 129-133
Connecting rod nuts 56-58
Manifold nuts 25-27
Rocker arm shaft bracket nuts 25-27
Flywheel cap screws 66-69
Spark plugs 30

I'm a disabled farmer here in Missouri, I try to get on here as often as I can, so if you need any other info I will try to get it for you as quickly as possible, hope this helps you out. Have a nice day!
Best wishes and regards,
Jeff (Continental1850)
