The popular Eaton No Spin Locker Positraction units are available for over the past 50 years, the NoSPIN differential has been successfully utilized by a variety of on/off road vehicle/axle manufacturers. Traditional applications are Medium/Heavy Truck, Construction, Mining, Forestry, Agricultural, Military and Specialty Vehicles.

 

The following guidelines are examples of successful NoSPIN differential application:
Applications:
• 6x4 (tandem-drive axle) Trucks Primary location - forward rear. Both rear axles for maximum mobility if used 75% off-road.
• 4x4 Off-Road Vehicles Farm tractors (articulated & rigid) front axle. Also rear axle for maximum traction.
• Farm Tractors (straight frame with front-wheel-drive) -front axle only  (cannot be used in rear axle with individual wheel brakes).
• Loader - One axle only, either front or rear.
• Trencher - One or both axles.

• Front drive axles of Light Trucks. 

 

The performance of a vehicle equipped with a Heavy Duty NoSPIN Locker differential is somewhat different from that of a vehicle
equipped with a conventional differential.

 

For example:  When turning a corner, the sound of component disengagement and re-engagement may be audible, and the transfer of
driving torque from both wheels to one wheel may be noticeable.  When going from drive (acceleration) to coast (deceleration) in a turn, a "metallic" sound may be heard as torque flow is reversed (inside wheel engaged during acceleration; outside wheel engaged during deceleration).

 

These characteristics are normal because of backlash designed into the NoSPIN differential, which is of a fixed amount (1 to 2 inches of rotation at the tire tread).  Backlash or slack between the driving and driven clutch teeth is an inherent part of the NoSPIN and necessary to permit automatic operation when driving in forward and reverse. The total backlash in the driveline is increased by the amount of the reduction between the ring gear and pinion. If the ring gear-pinion ratio is 5 to 1, the total backlash in the driveline with the NoSPIN would be about 30°. This in turn is increased by clearances between planetary gear, sliding splines and the ring and pinion gear. We feel that the total driveline slack can amount to as much as 1/4th turn of the driveline without being abnormal, but if it exceeds 1/4 turn, other parts in the drivetrain could be checked.
