Differentiation by Matched Gearbox Model
Different QD40 series PTOs need to match specific gearbox models, which is the core basis for differentiation:
1.Matching 8JS75,8JS85C,8JS85E , 8JS85E-C, 8JS95E-C ,8JS75TE gearbox:
QD40A (18/19,0.92), QD40J (18/34,0.92), QD40J-A (16/34,1.06),QD40K (16/34,1.18),
QD40C (16/34,0.93) ;Aftermarket part 16/30, SQD-FS34/29(1.25),FLQ34-29,FLQ-3029, HWP-F34/31( 0.94)
Associated number: 17JK-G18569 (may be the assembly number of the PTO matched with this gearbox)
2.Matching 8JS75TC gearbox:
◦ QD40L (22/42,1.1), QD40B(21/31,1.07) ,8JS85F QD40B(22/31,1.07)
◦ Associated number: G30468 (corresponding to the PTO matching number of this gearbox)
3.Matching 8JSX95TM gearbox:
◦ QD40N(19/28 ）
II. Differentiation by Gear Tooth Ratio and Speed Ratio
The gear tooth ratio (drive gear: driven gear) directly determines the speed ratio, which in turn affects the output speed and torque characteristics of the PTO, making it a key performance parameter:

III. Differentiation by Performance and Application Scenarios
1.Speed-increasing type (speed ratio < 1, e.g., QD40A):
Suitable for equipment requiring high-speed output (such as high-speed operating devices driven by hydraulic pumps), commonly used in light special vehicles (e.g., small sprinklers, cleaning vehicles).
2.Speed-reducing type (speed ratio > 1, e.g., QD40K, QD40L, QD40N):
Suitable for heavy-duty equipment requiring high torque output (e.g., concrete mixers, large cranes, dump truck lifting systems), which increases torque by reducing speed.
3.Near-constant speed type (speed ratio ≈ 1, e.g., QD40B):
Balances speed and torque, suitable for scenarios with high requirements for speed stability (e.g., precision hydraulic control systems).
IV. Differences Between Original and Aftermarket Parts
• Original parts (e.g., QD40A/J/K/L/B/N):
Strictly match the size, tooth count, and strength standards of the corresponding gearbox, with high reliability. They usually have formal numbers (e.g., 17JK-G18569, G30468) and guaranteed compatibility.
• Aftermarket parts (16:30 teeth):
As replacement parts, they have different tooth counts from the original, which may lead to dimensional deviations or insufficient strength. It is necessary to test the installation compatibility and transmission stability with the gearbox. They are recommended for non-heavy-duty or temporary replacement scenarios.
In summary, when differentiating QD40 series PTOs, it is necessary to first confirm the matched gearbox model, then judge their performance characteristics based on tooth count and speed ratio, and finally select the appropriate model according to operational requirements (speed/torque) and the nature of original/aftermarket parts.
