`87 446: Starter always worked fine, removed and placed on shelf during engine swap. Light lube on the shaft, reinstalled and carefully adjusted so that it meshes properly with the flywheel. Wired it up to verify oil pressure with my newly installed gauge and now the starter clutch ( what I call the Bendix) doesn`t drive the *&^#%^* f-wheel ! You can view it`s operation through the hole for the coil mount. Drives forward, meshes perfectly, starter motor turning, but evidently the sprag clutches inside decided to take a vacation. Of course had I been smarter I would have tested this BEFORE I installed the blower housing/ PTO / heat exchanger etc. I have replaced more than a few of these on H-D Shovelheads and Sportsters over the past 30 years, BUT they ordinarily give intermittent failure warnings before they give up the ghost. Oh no, not this inaccessable little bastardo. I have two starters in stock and had there been ANY question, I would have swapped one in. So... rather than test firing my new engine on Saturday and motoring happily about the yard, I`ll be digging back inside because I`m stupid. ARRGGG !!!
