Komatsu D41P-5A–D65P-12E: older chassis and D65-12 steering
The D65EX-12 steering motor does not replace its torque converter
Komatsu’s American AESS453-00 brochure identifies a TORQFLOW transmission for the D65EX-12, EX-12 LT and PX-12. Its converter and planetary powershift gearbox provide the three forward and three reverse ratios. HSS describes another part of the driveline: a hydraulic motor and differential planetary steering mechanism.
Calling the entire machine hydrostatic would blur that distinction.
The steering arrangement keeps power flowing to both tracks as their speeds change through a turn. The brochure also describes counter-rotation. Its left joystick combines direction, steering and wrist-operated gear selection, while the right lever controls the blade.
The CLSS implement circuit links blade response to lever movement and maintains work-equipment control when steering takes priority.
For inspection, the same publication locates power-train pressure test ports beside the operator platform on the right. The equalizer-bar center pin has remote greasing. Gas-assisted gull-wing covers expose the engine compartment.
Those locations help distinguish an inaccessible service point from one simply concealed by added guards.

The Japanese DJS141003 brochure covers D60P-12 and D65E/P/EX/PX-12 configurations. It explains that the new HSS machines and the conventional clutch-and-brake machines use the same steering-lever operating pattern. A familiar lever therefore does not prove that the internal steering mechanism is identical.
That publication reserves its HSS explanation for the D65EX and D65PX. Its diagram shows a steering motor, planetary mechanism and wet disc brakes. The service-access section separately describes a coolant reserve tank, grouped filters and an engine-side opening assisted by a gas spring.
The listed equipment belongs to that Japanese publication; it does not turn every earlier D65A or D41 into the later EX arrangement.

SEBM001922 starts with serial60001 for the E, P, EX and PX models. Its cover names four engine families and directs engine work to the separate 125-Series or 125-2-Series book. The chassis document alone is not a complete engine repair manual.
Read the engine plate as well as the dozer serial number before selecting that companion volume.
