Re: 700R4 build thread.
Reaction Sun Gear Mods.
Grind 4 small notches in the Face of the Sun Gear that rides on the Reaction Planet internal bearing.
This improves oiling to the bearing & Planet.
Replace the Bushing with a Wide Sonnax bushing, In the old day's we doubled the stock bushing.
This adds stability to the Input Planet, Reaction Tube & Sunshell.
Install Sun Gear into the Planet.
