The Minor's method of pivoting the swivel pin (upright) on a threaded housing is quite foreign to most of us, but it actually works fine when everything is in perfect condition. The lower trunion has the steel fulcrum pin riding directly on bronze bushes. When wear occurs here it is possible to replace just the pin, but this usually accounts for only half the wear. The best long range solution is to replace the entire trunion assembly. A trunion kit includes the trunion itself, pivot pin, nuts, washers, dust seals, etc.
