Peterbilt is now spec'ing Eaton Fuller's new FR Series 10-speed transmissions on its trucks. The transmissions, which replace the RT Series 10-speeds, provide a weight savings of up to 32 lb. and offer better reliability as a result of wider gears, higher-capacity bearings and larger shafts.
A new shift mechanism means improved shift quality and a tighter shift pattern. Vehicle uptime is also increased, the result of changes in the output seal system, air system and synchronizer design. Gear ratios and shift ratios are unchanged.
The OEM also offers the Eaton Fuller AutoShift Generation II 9 Series. Changes to the 9 Series include a new output seal system for improved durability and performance, and a 54-spline output shaft for greater strength.
