Overdrive Brake: Disassembly

Prior to disassembly, check OD brake clutch pack clearance. Using a feeler gauge, measure clearance between snap ring and flange. See Fig 1. Clearance should be .014-.075" (.35-1.91 mm). If clearance is not as specified, inspect discs. Remove snap ring from OD case. Remove flange, discs, plates and cushion plate. Note location and number of components. See Fig 2.
Remove OD planetary ring gear, thrust bearing and races from OD case. Remove snap ring, spring seat and piston return spring. See Fig 2. Remove brake piston by applying air pressure to OD case. Remove oil seal rings from case and "O" rings from piston.
