Service Bulletin

Description of Revisions: This bulletin replaces the version dated
February 2017. Instructions for finding transmission and PTO
procedures are revised. The MODs for the wiring and the air
system have been updated. Tables 1, 2, 4, and 5 are added.

Overview
The DT12 transmission is available with a rear mounted PTO prep option. The option includes all the vehicle
wiring and transmission elements needed to support the PTO without the addition of the PTO hardware on the
transmission. Check the information in PartsPro MOD 362, to confirm the vehicle being fitted with the PTO was
ordered with the prep option.

WARNING
Mounting a PTO to a DT12 transmission is supported only for GHG17 vehicles. Adding a PTO to older
models, or current models that were not ordered with PTO or PTO prep, will not work or may function
incorrectly. Vehicle and transmission warranty will be affected by installing an unsupported option, and
could be dangerous.
The additional hardware needed to complete the installation includes the PTO, a transmission oil pump drive
shaft, and a selection of shims. All the required components are available as three separate kits:
• PTO assembly (includes the PTO service part)
• PTO installation kit (includes the bolts, seals, oil pump driveshaft assembly, and oil pump thrust plate)
• Oil pump shim kit (includes the five most common shims required)

NOTE: Some chassis air system components may also be required.

Installation Information
Transmission
The installation process includes removing the non-PTO oil pump cover and oil pump driveshaft, determining
the oil pump shim needed, and installing the PTO. For the procedure, log into www.DTNAConnect.com, under
My Applications select PSL (Power Service Literature), then select the Transmission category.

Chassis
The wiring is detailed in MOD 885 and in PartsPro for VINs spec’d with PTO and PTO prep.
The air system is detailed in MOD 372, MOD 46D, and in PartsPro for VINs spec’d with PTO. See Table 2,
Table 4, and Table 5 for parts update and BOM reference information on installing the new equipment.

Mechanical
The PTO has length, speed, and pump requirements that need to be well understood by the equipment installer
and the customer. Inform the customer of the web-based information available on the DDCSN website, and
make sure they have access to the DT12 PTO Installation Guide (https://ddcsn-ddc.freightliner.com/cps/rde/
xchg/ddcsn/hs/6229.htm).

Parameters
The parameters needed to make the PTO function are included in the order specifications, and no changes
should be required when the PTO is installed. However, if the customer requires changes to the parameters,
refer to GHG14/GHG17 DDEC13 Electronic Controls Application and Installation manual on the DDCSN website
for available options (http://ddcsn-ddc.freightliner.com/cps/rde/xbcr/ddcsn/ddc-svc-man-0127.pdf).

Parts
