Rod cap cotter pin (1 Viewer)

While changing oil pan seal. No Leak just wanted to look at bottom end of Fj40 1969. I found four cotter pins missing and movement on pins on other castle nuts. Best way to install cotter pins to make the tight. Aviation on rotating part they turn them in to the side and into castle nut slots. Is this how or the over under style. They should not move.

I would torque them to spec. if need be tighten slightly more so the castle nut lines up with the hole in the stud and install the correct size cotter pin. I would not leave any castle nut without a cotter pin. Your just asking for trouble later on.

Torque all at 44fp but the cotter pin install method on a rotating mass, is there a preferred way.

Preferred method is stainless steel safety wire. tisted with a tie wire tool.

Can do it that way. But safety wire for drilled heads not a castle nut. I work on airplanes and have never used on the nut end.
