Cotters aren't torqued, they are press-fit. You can't get them too tight. I understand how torque values are modified from dry threading to "wet." This is different. There is no torque involved. The press specification is "at least 50lbs of pressure" according to Barnett's.

The idea behind lubrication is that they don't creek and squeek.
