Abstract
The invention herein comprises a kit and method that may be used to replace damaged and worn stabilizer bearings in both the Echo and Delta Apache helicopter. The kit includes a removal assembly that includes a bolt coupled to a cutting mechanism. Tightening of the bolt causes the cutting mechanism to cut the damaged and worn bearing from its housing. A staking mechanism is disclosed that allows the staking of a replacement bearing in the housing is provided. The staking assembly joins the replacement bearing to the housing so that it is tight. And, an installation assembly is disclosed that utilizes the bolt utilized in the cutting mechanism coupled to a hex nut.

A kit for replacing an aileron bearing in an aircraft stabilizer comprising:
- a removal assembly, wherein the removal assembly comprises:
- a bolt, wherein the bolt has sufficient length to traverse the aileron bearing and all components of the removal assembly when inserted into the aileron bearing,
- a cutting means, wherein the cutting means cuts the aileron bearing when rotated against the surface of the aileron bearing,
- a bearing bushing that is inserted into a ball of the aileron bearing,
- a spacer cup that catches the aileron bearing while the aileron bearing is being removed from the aircraft stabilizer,
- a hex nut, wherein the hex not is formed to screw onto the bolt, wherein tightening of the bolt into the hex nut causes the cutting means to rotate cutting the aileron bearing,
- a staking means, wherein the staking means comprises a staking anvil, wherein the staking means includes a cutting means to cut the edges so that a “V” groove is formed between an outer race of the aileron bearing and the edges of a housing that houses the aileron bearing,
- an installation assembly, wherein the installation assembly comprises:
- an installation bolt, wherein the installation bolt has sufficient length to traverse a replacement aileron bearing and all components of the installation assembly when inserted into the replacement aileron bearing, and
- an installation hex nut, wherein the installation hex nut is formed to screw onto the installation bolt, wherein tightening of the installation bolt into the installation hex nut causes the replacement aileron bearing to be positioned into the aircraft.
A removal assembly for removing an aileron bearing from an Apache helicopter stabilizer comprising:
- a bolt, wherein the bolt has sufficient length to traverse the aileron bearing and all components of the removal assembly when inserted into the aileron bearing,
- a cutting means, wherein the cutting means cuts the aileron bearing when rotated against the surface of the aileron bearing,
- a bearing bushing that is inserted into a ball of the aileron bearing,
- a hex nut, wherein the hex not is formed to screw onto the bolt, wherein tightening of the bolt into the hex nut causes the cutting means to rotate cutting the aileron bearing, and
- a spacer cup that catches the aileron bearing while the bolt is being tightened.
An staking and installation assembly for staking and installing an aileron bearing into an Apache helicopter stabilizer comprising:
- a staking means, wherein the staking means comprises a staking anvil, wherein the staking means includes a cutting means to cut the edges so that a “V” groove is formed between an outer race of the aileron bearing and the edges of a housing that houses the aileron bearing,
- an installation assembly, wherein the installation assembly comprises:
- an installation bolt, wherein the installation bolt has sufficient length to traverse a replacement aileron bearing and all components of the installation assembly when inserted into the replacement aileron bearing, and
- an installation hex nut, wherein the installation hex nut is formed to screw onto the installation bolt, wherein tightening of the installation bolt into the installation hex nut causes the replacement aileron bearing to be positioned into the aircraft.
