Inspection [12/2013 - ]: Procedure

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

INSPECT PRELOAD

Inspect Driven Pinion Preload:

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

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

PRELOAD (AT STARTING)

Item	Preload
without SST	0.5 to 0.9 Nm (5 to 9 kgfcm, 4 to 8 in.*lbf)
with SST	0.3 to 0.6 Nm (3 to 6 kgfcm, 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.).
Refer to PRECAUTION [12/2013 - 11/2016] , or refer to PRECAUTION [11/2016 - ]
The "with SST" torque value is effective when SST is parallel to the torque wrench.

Inspect Total Preload:

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

PRELOAD (AT STARTING)

Item	Total Preload
without SST	0.4 to 0.5 Nm (4 to 5 kgfcm, 3.5 to 4.4 in.*lbf) + Driven pinion preload
with SST	0.25 to 0.38 Nm (3 to 4 kgfcm, 2 to 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.).
Refer to PRECAUTION [12/2013 - 11/2016] , or refer to PRECAUTION [11/2016 - ]
The "with SST" torque value is effective when SST is parallel to the torque wrench.

INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVEN PINION

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

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)	-	-

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

INSPECT RUNOUT OF RING GEAR

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

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

0.06 mm (0.00236 in.)

INSPECT TRANSFER RING GEAR MOUNTING CASE

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

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

0.04 mm (0.00157 in.)
