Installing the bearing is actually quite easy. It requires some threaded rod, use at least 1/2", about four nuts, and some large and thick washers.
The most difficult part is actually getting the bearing started. You want it to go in perfectly straight so care must be taken to get it perfectly straight before beginning to tighten the threaded rod. If it goes in crooked it will bind and yo can ruin the bearing.
You may want to lube the inside of the strut and the outside of the cutlass with regular Ivory soap in bar form. Once the soap gets wet it dissipates and unlike grease or other lubes will not compromise the press fit of the bearing in the strut.
