MF1A TRANSFER / 4WD / AWD: TRANSFER ASSEMBLY: INSPECTION

1. INSPECT PRELOAD

(a) 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):





NOTICE:
* 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.) Service Precautions.
* The "with SST" torque value is effective when SST is parallel to the torque wrench.
(b) Using SST and a torque wrench, measure the total preload.

2. INSPECT RING GEAR BACKLASH

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





Backlash:

0.14 to 0.25 mm (0.00551 to 0.00984 in.)

(b) If the backlash is not within the specification, adjust the side bearing preload or repair as necessary.

NOTICE:
Check at least 3 positions on the circumference of the ring gear.

3. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVEN PINION

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





(b) Rotate the ring gear 10 times more.

(c) Rotate the ring gear to inspect the tooth contact pattern.





(d) 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 RING GEAR RUNOUT

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





(b) 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 RUNOUT

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





(b) Using a dial indicator, check the runout of the ring gear mounting case.

Maximum runout:

0.04 mm (0.00157 in.)
