Title: JF2A TRANSFER / 4WD / AWD: TRANSFER ASSEMBLY: INSPECTION (2008 LX570)

INSPECTION

1. INSPECT TRANSFER INPUT SHAFT

(a) Using a micrometer, measure the diameter of the input shaft journal surface.

Minimum Diameter:

68 mm (2.68 in.)

If the diameter is less than the minimum, replace the input shaft.

(b) Using a dial indicator, measure the inside diameter of the input shaft bush.

Maximum Inside Diameter:

46 mm (1.81 in.)

If the inside diameter is more than the maximum, replace the input shaft.

2. INSPECT TRANSFER LOW PLANETARY GEAR ASSEMBLY

(a) Using a feeler gauge, measure the thrust clearance of the pinion gear.

Standard Clearance:

0.11 to 0.85 mm (0.00434 to 0.0334 in.)

Maximum Clearance:

0.85 mm (0.0334 in.)

If the clearance is more than the maximum, replace the low planetary gear assembly.

(b) Using a dial indicator, measure the radial clearance of the pinion gear.

Standard Clearance:

0.01 to 0.04 mm (0.000434 to 0.00150 in.)

Maximum Clearance:

0.04 mm (0.00150 in.)

If the clearance is more than the maximum, replace the low planetary gear assembly.

3. INSPECT REAR TRANSFER OUTPUT SHAFT

(a) Using a micrometer, measure the diameter of the output shaft journals.

Minimum Diameter:

Journal

Specified Condition

A

38 mm (1.50 in.)

B

42 mm (1.65 in.)

C

49 mm (1.93 in.)

If the diameter is less than the minimum, replace the output shaft.

4. INSPECT NO. 1 TRANSFER GEAR SHIFT FORK AND FRONT DRIVE CLUTCH SLEEVE

(a) Using a feeler gauge, measure the clearance between the clutch sleeve and gear shift fork.

Maximum Clearance:

0.8 mm (0.0315 in.)

If the clearance is more than the maximum, replace the clutch sleeve or shift fork.

5. INSPECT AND ADJUST NO. 2 TRANSFER GEAR SHIFT FORK AND HIGH AND LOW CLUTCH SLEEVE

(a) Using a feeler gauge, measure the clearance between the clutch sleeve and gear shift fork.

Maximum Clearance:

3.15 mm (0.124 in.)

If the clearance is more than the maximum, replace the clutch sleeve or shift fork.

6. INSPECT NO. 1 SYNCHRONIZER RING

(a) Apply gear oil to the cone of the input shaft, and check that it does not turn in both directions while pushing the No. 1 synchronizer ring.

If it can turn, replace the No. 1 synchronizer ring.

(b) Push the No. 1 synchronizer ring to the cone of the input shaft. Measure the clearance between the No. 1 synchronizer ring and input shaft.

Standard Clearance:

0.86 to 1.54 mm (0.0339 to 0.0606 in.)

Minimum Clearance:

0.86 mm (0.0339 in.)

If the clearance is less than the minimum, replace the No. 1 synchronizer ring with a new one.
