Thrust Needle Bearing
Thrust needle bearingVTD MODEL
Insert the rear driveshaft into the reduction drive gear and center differential assembly.
(A) Rear drive shaft
(B) Center differential carrier
Using the special tool, measure the distance A between the mating surface of extension case and multi-plate clutch (LSD) piston.
ST 32005073 GAUGE
A: Measured value
Using the ST, measure the distance B between the mating surface of transmission case and reduction drive gear edge.
ST 32005073 GAUGE
B: Measured value
Formula:
Note:
^ Calculation of "T":
When clearances are 0.05 mm (0.0020 inch), select up to four adjusting shims from the table, suitable for clearance value.
When clearances are 0.05 mm (0.0020 inch)
T= A - B + 0.40 mm
[T: A - B + 0.0157 inch]
When clearances are 0.25 mm (0.0098 inch)
T6: = A - B + 0.20 mm
[T = A - B + 0.0079 inch]
T: Shim clearance
A: Distance between extension case edge and rear driveshaft edge
B: Distance between transmission case edge and reduction drive gear edge
T: Shim thickness
0.05 - 0.25 mm (0.0020 - 0.0098 inch)
Example:
When, A = 90.50 mm (3.5630 inch), B = 90.35 mm (3.5571 inch)
Calculation for 0.05 mm (0.0020 inch) of clearance T6: 90.50 - 90.35 + 0.4 = 0.55
[T: 3.5630 - 3.5571 + 0.0157 = 0.0216]
Calculation when clearance is 0.25 mm (0.0098 inch)
T = 90.50 - 90.35 + 0.2 = 0.35
T = 3.5630 - 3.5571 + 0.0079 = 0.0138]
^ Calculation formula for T6: is applied when measuring using ST (32005073 GAUGE). When not using ST, apply T6: (A - a + 0.45 mm) - (B - H
T = (A - a + 0.0177 inch) - (B - B) - H].
T = Thrust needle bearing thickness
A: Distance from end of extension case to rear drive shaft ball bearing outer ring contact surface
B: Distance from end of transmission case to end of rear drive shaft ball bearing
a: Collar thickness used when measuring A
B: Collar thickness used when measuring B
0.45: Gasket thickness (mm)
H: Shim clearance
After calculation, the value of T6: becomes between 0.35 mm (0.0138 inch) and 0.55 mm (0.0216 inch), therefore select two shims with thickness of 0.2 mm (0.010 inch) or one shim with thickness of 0.5 mm (0.020 inch).
