Halo Morningstar Spin Doctor Grease Injector Tool

Halo/Morningstar Spin Doctor Grease Injector tool. Specially developed by Morningstar tooling, this relatively simple tool allows long lasting grease to be pressure injected inside the bearings and pawls of the Spin Doctor freehub - without the need for complete disassembly. To Grease; Push-in the Freehub injector tool into the end of the freehub and apply grease into the tool via a grease gun, until you can see a small amount grease purging out of the backside of the freehub. High quality grease injection will provide long lasting lubrication. This tool can also be used to purge a contaminated freehub of old lube, water and grit. (Simply continue injecting excess grease, and the excess grease will be forced out of the back of the freehub, taking with it existing contaminants.)
