Layshaft end bearing retrofit with external positive oil pressure delivery

An end bearing assembly for supporting an end of a rotary shaft, comprising:

• a bushing for captive insertion within the end of the rotary shaft;
• a stud for insertion into the bushing and on which the bushing rotates;
• and
• a flange mechanically secured to the stud for mounting the end bearing assembly to an external surface of an engine.

A method of retrofitting an end bearing assembly for supporting an end of a rotary shaft of an engine, comprising:

• inserting an assembly of a cap and a bushing into a hollow end of the rotary shaft, wherein the cap includes a cap portion and a post portion, wherein the post portion is inserted through a central void within the bushing during the inserting;
• securing the cap and bushing within the hollow end of the rotary shaft by inserting and expanding a snap ring into a groove within the hollow end of the rotary shaft;
• inserting a stud into the bushing and around the post portion of the cap, wherein the stud has a central void for accepting the post portion of the cap;
• and
• securing a flange mechanically connected to the stud to an outer surface of the engine.
