The threaded bushings are 1" diameter stainless steel rod, 1.8" long, that are drilled and tapped for the 1/2" diameter tierods.
The outer stainless steel bushings have 1 1/8" outside diameter and a 1" inside diameter and are 1 1/8" long. The bushings have a hole cleared in the side for the 1/2" tierods.. Note that the chainplate
s can flex during fabrication, so the sleeves might have to be ground down slightly to provide proper clearance between the ears.
If your boat has experienced a leak at the chainplate
, remove the entire chainplate
from the boat and inspect it carefully. Salt water held against the stainless steel for an extended period at deck level will often cause crevice corrosion that will not be visible from above or below. This corrosion can compromise the integrity of your entire rig. Leaks can often damage these threaded bushings and sleeves as well as the tierods, so inspect each component of the rig support carefully.
