Application Definitions
• Domestic applications - restricted to North America, Europe, Brazil, Japan, Australia,
and New Zealand.
• Export applications - outside of North America, Europe, Brazil, Japan, Australia, and
New Zealand.
*Driveline sizing for export applications is based on Maximum Driveshaft Torque and
Bearing Life calculations only. The wheel slip torque calculation is not used for
Export applications due to overload conditions that can occur in these regions.
Transit Bus Vehicles used to transport passengers over city or suburban routes making multiple stops per hour.
Vehicles used to transport people and equipment to the site of an emergency to extinguish fires and evacuate and
Fire/Rescue
transport injured victims to a medical facility.
Vehicles specifically designed to transport passengers to and from school and extracurricular activities. Includes Prison and
School Bus
church busses.
Vehicles used for non-commercial transportation travelling less than 30,000 mi. (48,280 Km) per year. May pull a small
Recreational Vehicle

* Compare the Low Gear Torque (LGT) calculated in step 1 and the Wheel Slip Torque
(WST) calculated in step 2 and use the lower of the two values as the “application
torque” to select the appropriate driveline Series from table 2 on page 9. The
maximum torque rating of the selected Series must be equal to or greater than the
application torque value.
Step 3 – Calculate the Universal Joint Bearing Life (B10) for the Series
selected in Step 2.
(𝟏𝟎/𝟑)
B10 = 𝟗𝟖, 𝟎𝟎𝟎 𝒙 (𝑨𝑹/(𝑺𝑳𝑹 𝒙 𝟏. 𝟎𝟒))(𝟕/𝟑) 𝒙 <𝑩𝑭/(𝑮𝑪𝑾 𝒙 𝑨𝑭)? (Km)
Note: The bearing life formula assumes a universal joint true operating angle ≤ 3°. For
main driveline applications with static universal joint true operating angles in excess of
3° the formula can be adjusted by replacing the 98,000 constant value with 294,000 ÷
true operating angle.
Step 4 – Compare the B10 universal joint bearing life value calculated in step 3 to
the Bearing Life Requirement (B10) for your application listed in table 1 on page
9. The calculated B10 bearing life must exceed the requirement of the vehicle
application. If the B10 bearing life does not meet the application requirement
repeat step 3 for the next larger Series until the B10 requirement is met.

Note: High angle (45°) interaxle driveshafts are available in C2045, C2055, SPL170,
SPL250 and 1710 Series only.
Step 2 – Calculate the Universal Joint Bearing Life (B10) for the Series
selected in Step 1 using the following formula.

B10 = 𝟐𝟗𝟒, 𝟎𝟎𝟎 𝒙 (𝑨𝑹/(𝑺𝑳𝑹 𝒙 𝟏. 𝟎𝟒))(𝟕/𝟑) 𝒙 <𝑩𝑭/(𝑮𝑪𝑾 𝒙 𝑨𝑭)? (Km)
GCW = Maximum Gross Combination Weight (Kg)
AF = Application Factor (See Table 1 on Page 9)
SLR = Drive Tire Static Loaded Radius (m)
AR = Axle Ratio
BF = Universal Joint Bearing Factor (Nm) (See Table 3 on Page 10)
Note: For interaxle driveline applications with static universal joint true operating
angles in excess of 6 degrees contact Spicer Engineering.
Step 3 – Compare the B10 universal joint bearing life value calculated in step 2 to
the Bearing Life Requirement (B10) for your application listed in table 3 on page
10. The calculated B10 bearing life must exceed the requirement of the vehicle
application. If the B10 bearing life does not meet the application requirement
repeat step 2 for the next larger Series until the B10 requirement is met.
For tridem applications, the 2nd interaxle driveshaft can be the same or one
Series smaller than the forward interaxle driveshaft (torque capacity and B10 life
calculations are not needed).

Driveline Sizing
* Some applications require deep reduction transmissions for speed-controlled operations such
as paving and pouring. In these applications it may be more appropriate to use the second
lowest forward transmission ratio to calculate the Maximum Low Gear Torque. To use the
second lowest forward gear ratio to calculate LGT, all three of the following conditions must be
met:
1. Lowest forward gear ratio numerically greater than 16:1.
2. Split between the lowest forward gear ratio and the second lowest forward gear ratio is greater
than 50%.
3. Startability Index must be greater than 25 (see below calculation).

Series must be equal to or greater than the application torque value.

Note: The bearing life formula assumes a universal joint true operating angle ≤ 3°. For
main driveline applications with static universal joint true operating angles in excess of
3° the formula can be adjusted by replacing the 60,900 constant value with 182,700 ÷
true operating angle.
Step 4 – Compare the B10 universal joint bearing life value calculated in step 3 to
the Bearing Life Requirement (B10) for your application listed in table 1 on page

Center Bearing Mounting
Spicer heavy duty center bearings must be mounted within 3° of perpendicular to the
coupling shaft centerline as shown in Figure 1 below and the center bearing assembly
must not operate with a linear offset greater than 1/8 inch as shown in Figure 2.
Note: The Spicer "Dura-Tune®" self-aligning center bearing may be mounted up to
+/- 10° of perpendicular to the coupling shaft centerline as shown in the side view
of Figure 1. The rubber isolator must remain perpendicular to the coupling shaft
centerline within 3° as shown in Figure 1.

To find the true joint angle of each joint, first find the top-view and side-view angles of each joint. The
top-view angle of Joint A is equal to 0.67 - 0.00 = 0.67 and the side-view joint angle of Joint A is equal
to (-4.0) - (-1.3) = -2.70. By putting the top-view angle (0.67) to the X-axis and the side-view angle
(-2.70) to the Y-axis, the true joint angle of Joint A is equal to 2.78°∠283.94°.
Note: The true joint angle is a vector: the 2.78° is the magnitude and the 283.94° is the argument. The
true joint angles of joints A, B, and C are shown in the following chart.
