MPT Model
Measure distance "A" from end of extension case and rear drive shaft with ST.
ST 32005073 GAUGE
- A: Measured value
Measure the distance "B" from the transmission case mating surface to the reduction drive gear end surface with ST1 and ST2.
ST1 32005073 GAUGE
ST2 32005133 GAUGE
- B: Measured value
Calculation formula:
- Calculate "T":
T = A - B + 35.4 mm
[T = A - B + 1.3937 in]
T: Thrust needle bearing thickness
A: Distance from end of extension case to end of rear drive shaft
B: Distance from end of transmission case to end of reduction drive gear
Example:
When, A = 33.6 mm (1.3228 in), B = 65.05 mm (2.5610 in)
T = 33.6 - 65.05 + 35.4 = 3.95
[T = 1.3228 - 2.5610 + 1.3937 = 0.1555]
After calculation, the valve of "H" becomes 3.95 mm (0.1555 in), therefore select bearing thickness of 3.8 mm (0.150 in).
- Calculation formula for "T" is applied when measuring using ST (32005073 GAUGE, 32005133 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 end of reduction drive shaft
B: Distance from end of transmission case to end of rear drive shaft
a: Collar thickness used when measuring "A"
b: Collar thickness used when measuring "B"
0.45 (0.0177): Gasket thickness (mm (in))
H: Shim clearance
