DAF PTOs connect truck gearboxes to hydraulic pumps for tipping, walking floors and cranes. DAF trucks use various transmission types requiring matching PTO configurations.
ZF Traxon 12TX and 16TX transmissions in CF and XF Euro 6 models need rear-mounted units with pneumatic controls. Check transmission plates on gearbox casings for accurate model information before selecting compatible mounting types.
LF models fitted with ZF 6S series gearboxes accept direct-mount PTOs without additional drive shafts. S5-42 transmissions on earlier LF trucks need right-side mounting patterns for proper alignment with hydraulic system components.
Eaton transmissions in older DAF trucks use different mounting patterns. Models with FS/FSO 4106 and 5206 gearboxes accept twin-wheel units for medium-duty applications typical in distribution fleets.
Torque ratings and configurations
Standard 1:1 ratio PTOs deliver 479.5 Nm output for routine distribution-tipping operations. This configuration suits everyday transport cycle demands without adding mechanical strain during operation.
Twin-wheel 1:1.2 ratio units produce 260 Nm through dual-gear engagement systems. Load distribution across multiple contact points reduces wear during extended running periods, which are common in construction applications.

Clutch models with 1:1 ratios generate 531 Nm for walking floors and heavy-duty equipment. These units allow engagement while vehicles move at speeds up to 15 mph, which is beneficial for trucks stopping frequently during routes.
S5-42 transmissions run dual-ratio 1:0.88 configurations with 206 Nm ratings. Side-mounted designs work with compact pump arrangements suited to light commercial applications where space constraints affect installation options.
Confirmation switch integration
Modern DAF PTOs have built-in dashboard indicators showing engagement status. Confirmation switches display visual warnings, preventing drive-away damage when power transfer systems remain active.
ZF Traxon transmissions need electronic integration through solenoid interfaces. Connection ports link directly with vehicle management systems, enabling automated protection based on operational parameters.

Pneumatic control systems on standard units connect via 1/4″ BSP air-line fittings. Cab switches operate through management interfaces and air systems rather than mechanical linkages for smoother engagement without transmission damage.
CF and XF model requirements
CF models with ZF 6S 700 to 9S 1310 transmissions use rear-mounted 479.5 Nm units. Mounting patterns match gearbox casings for direct fitment without additional bracketry or hydraulic line modifications.
XF trucks with 12S and 16S transmissions require quill shaft components with 213mm drive systems. Accessory engagement connects through intermediate shafts matched to specific transmission specifications for optimal performance.
Depending on application demands, Traxon gearboxes in both CF and XF accept twin-wheel or clutch-type designs. The extensive transmission list requires checking compatibility across 12TX and 16TX variants before specification and fitting.
LF model considerations
LF trucks with ZF 6S 850 transmissions work with twin-wheel 260 Nm PTOs. Small chassis dimensions mean compact PTO designs better suit installation constraints than larger units from heavier vehicle ranges.

Due to gearbox design features, S5-42 transmissions need side-mounted units. Dual ratio configurations accommodate 4.65 and 5.72 gearbox ratios without needing model-specific PTO variants for different transmission specifications.
Early LF models with Eaton transmissions use twin-wheel designs. Different mounting patterns compared to ZF units require proper identification before installation to prevent casing damage during mounting.
