Lubrication rings for aircraft engine bolts

A method, comprising:

• controlling a temperature of a layer of lubrication material to be below a phase-change temperature associated with the lubrication material, wherein the lubrication material is in a non-solid state when above the phase-change temperature and the lubrication material is in a solid state when below the phase-change temperature;
• cutting a plurality of self-supporting lubrication rings out of the layer of lubrication material while the layer of lubrication material is below the phase-change temperature;
• and
• gathering the plurality of self-supporting lubrication rings for further use while the plurality of self-supporting lubrication remains below the phase-change temperature.

A method of manufacture, comprising:

• forming a self-supporting lubrication ring out of a layer of lubrication material at or below a first temperature, wherein the lubrication material is solid at the first temperature;
• mounting the self-supporting lubrication ring onto a shank of a bolt and axially abutting the self-supporting lubrication ring against a head of the bolt while the lubrication material is at the first temperature;
• arranging the bolt with a first engine component and a second engine component such that the lubrication material is axially between the head of the bolt and the first engine component and the shank of the bolt is disposed in a first aperture of the first engine component and a second aperture of the second engine component;
• and
• preloading the head of the bolt against the first engine component axially through the lubrication material, wherein the lubrication material is at a second temperature that is higher than the first temperature during the preloading of the head of the bolt, and the lubrication material is semi-solid at the second temperature.
