  3. Insert actuating lever (cam end) into position in brake assembly. Install and tighten brake assembly mount bolts. Attach return spring to actuating lever, and bend long end of spring to snap over lever. Place mainshaft with flanged end up in vise using brass jaw protectors.
  4. Install brake drum and output flange onto flanged end of mainshaft. Install output flange onto brake drum, aligning marks made during disassembly. Proper installation maintains proper component balance. Install and tighten output flange mount nuts. Remove mainshaft and drum assembly from vise. Turn assembly over, and clamp in vise again.
  5. Install case onto mainshaft, guiding shaft through oil seal and bearing. Using Bearing Installer (T88T-2598-F), seat output bearing onto mainshaft. Install speedometer drive gear and snap ring onto mainshaft. Using Bearing Cup Installer (T88T-2598-D), install input bearing cup into housing.
    NOTE: Mainshaft shim determines end play. Shims are available in thicknesses increments of.0019" (.048 mm).
  6. Install shim on mainshaft. Install inner bearing onto mainshaft. To measure end play, install bearing spacer, without "O" ring, onto mainshaft. Clamp case assembly and mainshaft in vise. Use Lock Nut Socket (T70T-4252-D) to screw hex nut onto mainshaft.
  7. Mount a dial indicator between mainshaft and case. While rotating case assembly on mainshaft to center bearings, apply up and down pressure to take end play reading. End play should be.0019-.0039" (.048-.099 mm). Select proper shim to reach specified end play.
  8. Coat outer surface of NEW input oil seal with sealant. Install oil seal into case with sealing lip facing inward. Press seal in until it is fully seated.
