 The best tools ended up being a flat aluminum scrap piece and a hammer to 'set' the races in straight and a threaded rod and socket press to pull the races home. \\
 Just slight tapping was all that was required to get them started. \\
+The races will have a certain resistance when pressing them in. You'll feel the resistance and the races moving. \\
+If the resistance changes drastically (tightens suddenly), STOP, remove the tool and find out why. \\

 ====== Pivot Spacer Bushing ======
 ===== Removal =====
+This method uses the lockring inside the pivot to push / pull against for pressing the bushing out and back in. \\
+If the races are installed, simply use the outside pivot surface instead. The process is the same whichever bracing you use. \\
 **The FSM says to replace this bushing only if needed**. \\
 However, there is no criteria / spec to determine if it's needed. Use your best judgment. \\
 If it's really in bad shape, you'll know it when you see it. \\

 **Caution**: Use eye protection as the lockring may pop out on you. \\
 **There is no reason to replace this ring unless it's damaged or rusted to the point it will hinder proper bearing race installation**. \\
 The races butt up against this ring on both sides and that determines distance apart from each other thus how far the inner bearing race sticks out the end. \\
-So the races have to be installed correctly. \\
+This ring didn't need replacing but was replaced anyway for example. \\
-The ring can be used for both internal and external applications. However, the tool for these rings only works on external applications. \\
-It pushes each end outward to expand the ring to remove it from shafts and the like. \\
 There are no known pliers to compress the ring due to it having no holes or slots for pliers. \\
-So it will need to be pried out with screwdrivers in a circle pattern to get the ring out of the groove in the pivot. \\

+===== Installation =====
 The ring needs to be installed with a tapered sleeve so you can set it in one side and knock it into the bore while the sleeve taper narrows the ID of the ring. \\
 But without having that tool, a socket was bolted up into the bearing bore sitting on top of the open end of the ring to keep it from popping out. \\
 Then the other side of the ring was carefully knocked into the bore with a wooden dowel and a hammer. \\
-Once the ring was fully in the bore, the socket was used to know the ring down so it snapped into the groove. ((photos by Hippysmack)) \\
