Hi Frank & list!
On my TR4A, the zerks are NOT on or in the trunnions but in the vertical link
with a hole drilled down the center to the insert of the zerk is. You oil
through the zerk & it travles down the center of the Vertical Link & is forced
up around the threads & out the top of the trunnion where the grease cap or dust
excluder is.
