In response to poor core availability along with the high cost of replacing broken component parts, AMS offers a comprehensive line of new agricultural clutches. Manufactured by O.E. producers like AP Borg/Beck and Alma, these units fit applications including Fiat, Ford, Holland, and Kubota.

Obviously, tractor applications aren’t nearly as varied as automotive applications. Nevertheless, a variety of pressure plate and disc assembly designs are necessary to handle the high torque levels found in ag applications.

AMS pressure plate and disc assemblies are designed to address application specific requirements. In doing so, we insist on utilizing the following diaphragm and coil spring style pressure plate configurations.

 

Single Drive Plate Type Assembly - While similar to an automotive type assembly, some versions do utilize an independent power take-off (PTO) pack. This is the most common type ag assembly.

   

Split Torque or “Live Drive” Type Assembly - Contains a single driven plate with a spline hub that is permanently fixed to the assembly. The driven plate operates in conjunction with a gearbox input shaft and provides power to a separate PTO pack that is controlled by a separate hand lever.

   

Sequential Type Assembly - This assembly contains two driven plates, one for the transmission and the other for the PTO. A single foot pedal engages the transmission and PTO. Initial pedal movement disengages the transmission, while further movement disengages the PTO.

   

Independent Type Assembly - This assembly also contains two driven plates, however, the transmission and PTO are operated independently of one another. In most instances, a foot pedal engages the transmission, while a hand lever operates the PTO.

   

We also insist on using several application specific disc configurations. These designs include organic or sintered metallic facings, all matched with either rigid or spring dampened designs.

 

Rigid Designs contain no torsional damper springs in the center of the disc.

   

Dampened Designs contain torsional springs in the center of the disc. Torsional springs absorb load fluctuations in the driveline. While interchangeable in many instances, these discs are “design” specific.

   

Although organic material is typically used in most applications, the sintered material found on other applications provides greater resistance to wear and heat. Sintered material is also more tolerant of arduous operating conditions.
