Transfer Assembly: Inspection

WARNING: This page is about a different variant/trim than selected.

INSPECT PRELOAD
1. Using SST and a torque wrench, measure the preload of the backlash between the driven pinion and ring gear.
  SST 09326-20011
  
  Torque: Preload (at starting)
  
  0.30 to 0.53 N*m (3.0 to 5.4 kgf*cm, 2.6 to 4.7 in.*lbf)
2. Using SST and a torque wrench, measure the total preload.

  SST 09326-20011
  
  Torque: Preload (at starting)
  
  0.49 to 0.86 N*m (5.0 to 8.8 kgf*cm, 4.3 to 7.6 in.*lbf)
INSPECT RING GEAR BACKLASH
1. Using a dial gauge, check the backlash of the ring gear.
  Backlash: 0.10 to 0.18 mm (0.0039 to 0.0071 in.)
  
  If the backlash is not within the specification, adjust the side bearing preload or repair as necessary.
  
  NOTE: Check at least 3 positions on the circumference of the ring gear.

INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION
1. Coat 3 or 4 teeth at the 4 different positions on the ring gear with red read.
2. Rotate the ring gear, inspect the tooth pattern.

INSPECT RUNOUT OF RING GEAR
1. Place the transfer ring gear mounting case on the V-block.
2. Using a dial gauge, check the runout of the ring gear.
  Maximum runout: 0.06 mm (0.0024 in.)

INSPECT TRANSFER RING GEAR MOUNTING CASE
1. Place the transfer ring gear mounting case on the V-block.
2. Using a dial gauge, check the runout of the ring gear.
  Maximum runout: 0.14 mm (0.0055 in.)
