With that information, we can advise you to select the most adequate power take-off for your application.
Side: The window for installing the PTO is on the right or on the left side of the gearbox, always looking at the gearbox from the rear of the vehicle.
Rear: The opening window is on the rear of the gearbox, most common with ZF, MB ad Volvo transmissions.
Bottom: The window is in the bottom or "belly" of the box.
Based on the application, the pto shall have different outputs. The most common outputs are:
Flange to connect to a transmission (SAE 1100, SAE 1300, SAE 1400, DIN 90, DIN 100, DIN 120, etc.)
Bezares also offers rotation reverse adapters for those cases where there are no different options.
Simple: Also called direct. 1: 1 ratio
Multiplied: The ratio will be 1:> 1
Reduced: The ratio will be 1: <1.
In order to calculate the final ratio you just need to multiply the transmission's output ratio by the PTO's internal ratio.
Depending on the type of actuator, the power take-offs can be classified as follows:
Pneumatic: If the truck has air brake, it means that it has a compressor. They are usually driven at 7kg / cm2 – 8kg/cm2.
In small vehicles, where no compressor is available, it is possible to install one using the Bezares pneumatic pressure kit. It is an independent unit without maintenance, which provides a pneumatic line.
Mechanic: They are manually operated by means of a lever or cable that connects directly to the PTO's piston. With the movement of the cab's lever, the power take-off's fork moves internally and engages it.
Vacuum: When the truck has a depressor, it works through a vacuum line.
If your vehicle does not have one, it's also possible to install it using the Bezares' simple acting shifting kit.
Electric with motor: This actuator includes a small electric motor which moves a bar which diplaces the synchronizer until the pto is enganged. This system ensures always an easy engagement.
In contrast to the electric actuator with solenoid-type, the electric motor only works when engaging and disenganging the pto. This allows long working periods of time without power consume and avoiding possible damage to the vehicles battery.
Electrohydraulic: It incorporates an electrohydraulic actuator. They are normally used in the clutch PTOs for automatic Allison or Aisin gearboxes.
