TRANSFER ASSEMBLY INSPECTION

PROCEDURE

1. INSPECT PRELOAD

   
   

   1. Inspect Driven Pinion Preload:

      
      
      1. 

         *a	Length of SST 50 mm (1.97 in.)
         *b	Length of Torque Wrench 130 mm (5.12 in.)

         Using SST and a torque wrench, measure the preload of the backlash between the driven pinion and ring gear.

         SST

         09326-20011

         Preload (at Starting)

         Item	Preload
         without SST	0.5 to 0.9 N*m (6 to 9 kgf*cm, 5 to 7 in.*lbf)
         with SST	0.3 to 0.6 N*m (4 to 6 kgf*cm, 3 to 5 in.*lbf)

         Note

         
         

         • The "with SST" torque value is effective when using SST with a fulcrum length of 50 mm (1.97 in.).

         • The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 130 mm (5.12 in.).

         • The "with SST" torque value is effective when SST is parallel to the torque wrench.

   2. Inspect Total Preload:

      
      

      1. Using SST and a torque wrench, measure the total preload.

         SST

         09326-20011

         Preload (at Starting)

         Item	Total Preload
         without SST	0.4 to 0.5 N*m (4.1 to 5.0 kgf*cm, 3.6 to 4.4 in.*lbf) + Driven pinion preload
         with SST	0.25 to 0.38 N*m (2.6 to 3.8 kgf*cm, 2.3 to 3.3 in.*lbf) + Driven pinion preload

         Note

         
         

         • The "with SST" torque value is effective when using SST with a fulcrum length of 50 mm (1.97 in.).

         • The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 130 mm (5.12 in.).

         • The "with SST" torque value is effective when SST is parallel to the torque wrench.

2. INSPECT RING GEAR BACKLASH

   
   

   1. Using a dial indicator, check the backlash of the ring gear.

      Backlash
      0.14 to 0.25 mm (0.00552 to 0.00984 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.

3. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION

   
   

   1. 

      Coat 3 or 4 teeth at 4 different positions on the ring gear with Prussian blue.

   2. Rotate the ring gear 10 times or more.

   3. Rotate the ring gear to inspect the tooth contact pattern.

      

      *a	Proper Contact	*b	Heel Contact
      *c	Face Contact	*d	Select an adjusting washer that will shift the drive pinion closer to the ring gear (*b, *c)
      *e	Toe Contact	*f	Flank Contact
      *g	Select an adjusting washer that will shift the drive pinion away from the ring gear (*e, *f)	-	-

   4. If the tooth contact pattern is not correct, select a new transfer output shaft washer that is thicker or thinner as necessary and recheck.

4. INSPECT RUNOUT OF RING GEAR

   
   

   1. 

      Place the transfer ring gear mounting case on the V-blocks.

   2. Using a dial indicator, check the runout of the ring gear.

      Maximum Runout
      0.06 mm (0.00236 in.)

5. INSPECT TRANSFER RING GEAR MOUNTING CASE

   
   

   1. 

      Place the transfer ring gear mounting case on the V-blocks.

   2. Using a dial indicator, check the runout of the ring gear mounting case.

      Maximum Runout
      0.04 mm (0.00157 in.)
