ORIGINAL
Press one bearing cone of the bearing assembly (1) on to the bevel pinion and seat securely against the pump drive pinion. Install bearing cone set spacer on to the bevel pinion. Install the bearing cup retaining ring into the groove in the carrier bore.Place the carrier assembly onto bench with the pump side facing up. Install one bearing cup of bearing set (1) and seat against the retaining ring.Turn the carrier over so that the pump side faces down. Install the bearing cup spacer with the shoulder inside of the retaining ring. Install the remaining bearing cup and seat firmly against the bearing cup spacer and retaining ring.Place the carrier over the bevel pinion so that the pump side bearing cup seats on the bearing cone.Press the remaining bearing cone securely onto the bevel pinion, seating into the bearing cup.Lubricate and install O-ring (5) onto the bevel pinion against the bearing cone. Install seal spacer (9) over the bevel pinion with internal tapered edge toward the bearing cone and O-ring.Install the oil seal retaining ring (7) into the carrier bore groove. Apply non-hardening sealant to the outside surface of the oil seal (8) and install the oil seal firmly against the retaining ring (7).Install the bearing lockwasher (4) and locknut (2) onto the bevel pinion. Tighten the locknut to 150 lb-ft (203 N m) torque and bend tang of lockwasher (4) into slot of locknut.CURRENT
Clean preservative oil off of bearing cups and cones. Press bearing cone (4) onto bevel pinion and fully seat against pump drive pinion as shown. Install bearing cups (3) into bevel pinion carrier (1) with thick edge; small inside diameter against the shoulder. Install the bevel pinion sub-assembly into the carrier. Install the remaining bearing cone onto the bevel pinion. Install O-ring (7) onto pinion against the outer bearing cone. Install retaining ring (5) into bevel pinion carrier bore. Apply Permatex Aviation Form-A-Gasket liquid sealant to the outside surface of seal (6) and press into carrier bore with the open spring side of the seal facing the bearings. Apply light grease to the inside and outside surface of seal spacer (8) and install inside diameter chamfer for O-ring (7) toward the bearings.Install bearing lockwasher (9) and bearing locknut (10) onto pinion. Clamp pinion gear in workshop vise equipped with aluminum or bronze jaw protectors. Rotate bevel pinion carrier to align bearing cone rollers as you slowly tighten the bearing lock nut. When a slight drag is noticed as the bevel pinion carrier is rotated, remove carrier from vise and wrap nylon cord around the bevel pinion and slowly pull the cord at a steady rate and measure the resistance with a "fish scale". At the pump drive pinion diameter, the
