The Kenworth door service manual, publication KM811057, is the cab-section reference for the daylight door assemblies used on the 2005 interior of W900, T600, T800, T800W and C500 trucks. This eight-page factory document explains how to identify the correct door assembly for a given chassis and how to remove the door pad and glass without damage.
Identifying the 2005 interior — Kenworth door service
Kenworth began production of the 2005 interior on 06/27/2005, with some pilot trucks built earlier. A chassis with the new interior can be identified either by appearance or by searching ECAT for the instrument panel control unit, part number Q21-1029. Getting this right matters because the door hardware changed with the new interior, and the older prints no longer apply.
Door assemblies covered — Kenworth door service
The Kenworth door service manual references three daylight door assemblies — R25-1096, R25-1094 and R25-1088 — and explains how to select the correct one. To determine the right diagram, the technician goes to ECAT, enters the chassis number in Visual Search, and searches for “R25”. Companion drawings are cited too, including R97-1124 for door adjustment layout and S97-1171 for door trim installation.
Door pad and glass
The removal sequence is spelled out step by step so trim and glass are not damaged during the job:
- Pry off the two arm-rest screw covers and retain them
- Remove the arm-rest and door-pad fasteners
- Lift the door pad to reach the glass and window hardware
- Follow the order given to protect the trim clips
Why the manual matters
Because it ties the physical repair to the correct ECAT part lookup, the door service manual keeps a workshop from fitting the wrong daylight door assembly or breaking trim on removal. Issued by Kenworth Customer Service as KM811057, dated 07/13/05, it applies to the 2005-interior models above. Brand information is at the Kenworth site.
