Formula:

NOTE:

Calculation of "T":
When clearances are 0.05 mm (0.0020 in), select up to four adjusting shims from the table, suitable for clearance value.

When clearances are 0.05 mm (0.0020 in)

T = A - B + 0.40 mm

[T = A - B + 0.0157 in]

When clearances are 0.25 mm (0.0098 in)

T = A - B + 0.20 mm

[T = A - B + 0.0079 in]

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 in)

Example: When, A = 90.50 mm (3.5630 in), B = 90.35 mm (3.5571 in)

Calculation for 0.05 mm (0.0020 in) of clearance

T = 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 in)

T = 90.50 - 90.35 + 0.2 = 0.35

[T = 3.5630 - 3.5571 + 0.0079 = 0.0138]
Calculation formula for "T" is applied when measuring using ST (32005073 GAUGE). When not using ST, apply
T = (A - a + 0.45 mm) - (B - ) - H

[T = (A - a + 0.0177 in) - (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 "T" becomes between 0.35 mm (0.0138 in) and 0.55 mm (0.0216 in), therefore select two shims with thickness of 0.2 mm (0.010 in) or one shim with thickness of 0.5 mm (0.020 in).
