With this configuration the PTO drive shaft angle must be in the range of 1° to 6°.
Bolts and nuts for attaching the driveshaft to this adapter flange are not included in either of the Spicer kits.
Use standard torque values to attach bolts to adapter flange based on hardware material and grade.
3. DT12 Hydrocar P89 Rear Mounted PTO with Prep for Hydraulic Pump (1:1 PTO Ratio).
This configuration is the same as configuration #1 above, except that the PTO Drive ratio here is 1:1.
With configuration #3:
- The Rear PTO drive assembly mounting flange offers SAE-B mounting for 2 or 4 bolt configurations
and an SAE B-B 15 tooth spline as shown in Figure 3 above.
- The thread type for the 2 or 4 bolt pattern is M14 x 2.0 with a depth of 20mm. It is recommended to
use a bolt length that allows for thread engagement of 1-1.5 times the diameter of the bolt used to
connect the hydraulic pump. Unless otherwise specified by the pump manufacturer, use a bolt torque
of 26-30 lb-ft (35-40 Nm) for the fasteners mounting the pump to the PTO drive assembly.
- A transmission cooler will be added to DT12 configuration in SpecPro.
- Some exhaust configurations are not compatible with DT12 PTO. Please consult with your local
vehicle representative to obtain specifics.
- Harnesses and controls are included for PTO operation.
- The pneumatic line is installed.
- The PTO is ready for operation via dashboard mounted switch.
- Consult Section 8.28 of the GHG14/17 DDEC13 A&I Manual (DDC-SVC-MAN-0127) for CPC
parameterization.
4. DT12 Hydrocar P89 Rear Mounted PTO for Driveshaft (1:1 PTO Ratio).
This configuration is for applications utilizing a driveshaft in place of a direct mounted hydraulic pump. From
a hardware perspective, it is identical to configuration #2 above, except that the PTO Drive ratio here is 1:1
instead of the 1:1.32 of configuration #2 above.
With configuration #4, the customer must order the following parts from the DTNA PDC:
- Spicer 1350/1410 or 1310 flange kit. See Figure 4-5 above for installation pics of the driveshaft
adapter. The two available Spicer flange kit part numbers are:
 Spicer 1350/1410 Flange: A9472600317 (See Figure 6 for the dimensions)
 Spicer 1310 Flange: A9472600417 (See Figure 7 for the dimensions)
- A transmission cooler will be added to DT12 configuration in SpecPro
- Some exhaust configurations are not compatible with DT12 Rear PTO. Please consult with your local
vehicle representative to obtain specifics.
- Harnesses and controls are included for Rear PTO operation
- The pneumatic line is installed
- The PTO is ready for operation via dashboard mounted switch
- Consult Section 8.28 of the GHG14/17 DDEC13 A&I Manual (DDC-SVC-MAN-0127) for CPC
parameterization
To correctly install a Spicer flange kit onto the DT12 Rear PTO:
1. Remove cover plate on DT12 Rear PTO housing
2. Insert the stud “1” into the center of the splined PTO drive on the DT12
3. Tighten stud to a torque of 11 + 1.5 lb-ft (15 + 2 Nm)
4. Install the spacer “3” on the back of the flange “4”
5. Apply grease “OKS 200” on the profile spline of the flange “4”
6. Install flange “4” into the PTO gear, then install nut “5” and torque to 26 + 3.5 lb-ft (35 + 5 Nm)
