I recently replaced the old Raymarine ST-40 instruments with B&G Triton 2 at the helm. This involved removing the Yacht Specialties pedestal guard which required removing everything on the pedestal above sprocket. What I found wasn’t promising. The steering shaft has play that seems to be coming...
I discovered I have the original Yacht Specialties Steering Manual, which covers installation, chain, cables, quadrant, stops, Morse cable control head attachments, and so on in detail.
YS is long out of business but was the OE manufacturer for many Ericsons.
See below.
A better version now...
