A spline assembly, comprising:
- a spline shaft having a first end and a second end opposite the first end, wherein the first end is splined to engage a spline receiver of a primary drive system and comprises a substantially spherical alignment head, wherein the substantially spherical alignment head comprises an expendable hydrocarbon material that is caused to melt by operation of the primary drive system over time.
A spline assembly, comprising:
- a spline shaft having a first end and a second end, wherein the first end is splined to engage a spline receiver of a primary drive system and comprises a substantially spherical alignment head, wherein the substantially spherical alignment head comprises an expendable hydrocarbon material that is caused to melt by operation of the primary drive system over time, wherein the melted expendable hydrocarbon material mixes with lubricant fluid of the primary drive system.
