Detroit Truetrac – Helical-gear limited-slip (worm differential) is the modern replacement for the classic clutch-type posi. Under normal light throttle driving conditions, a Truetrac operates much like a standard open differential, allowing the rear wheels to rotate at slightly different speeds for smooth cornering.
The Truetrac is a helical gear limited slip differential, not a “locker”. The Truetrac operates by transferring power from the spinning wheel to the wheel with the most traction. If one tire breaks traction, the amount of rotation (or spin) is controlled by transferring the lost traction to the higher traction wheel.
How strong is the Eaton Truetrac?
The Truetrac designs have been produced within a maximum continuous torque range from 2,500 Lb-Ft to 25,000 Lb-Ft. Increased capacity can be accomplished by larger gears and more pinion sets.
Does a Detroit Truetrac work in reverse?
The Detroit Truetrac is a helical-gear style, limited-slip differential that maximizes wheel traction and enhances driving characteristics. Maintenance-free, it features smooth, automatic operation in forward and reverse.
The Truetrac’s proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its toughness, but its smooth and quiet operation as well.
Do Detroit lockers make noise?
When I step on and off the gas pedal, I hear the unit make a “clunking” noise. Why? This happens because Eaton Detroit Lockers have “backlash” or “slack” between the drive and driven teeth and you will hear this in everyday use going through corners and when transitioning from drive to coast.
Does a Detroit locker work in reverse?
It works in forward and reverse, and features unmatched strength, 100 percent automatic locking, and maintenance-free parts.
Can a differential be run in reverse?
You can flip the axle over all you want and you will change the driving direction from backwards to forwards, with the pinion and ring gear always meshing on the driving face of the gears..
How does a Harrop Truetrac work?
Truetrac gears have spiral teeth, and the pinions are mounted in pockets in the case. If one wheel begins to lose traction, the pinions separate slightly from the side gear, and wedge in the pockets. As input torque increases, the separating force increases, thus slowing or stopping the spinout.
Who makes Truetrac differentials?
Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque.
Does Truetrac need additive?
Do I need friction additive/modifier? A quality petroleum/mineral based oil works best in the Truetrac units. We do not recommend synthetic oil. Friction additive/modifier is not required.
A quality, petroleum-mineral based, GL5 rated 80w-90 gear oil should be used. Synthetic oils are not recommended for Truetrac applications.
Which differential locker is best?
For vehicles with open differentials, a rear locker is by far the more popular choice, as it’s more suitable to a diverse range of off-roading situations. “If the vehicle only has open differentials we typically recommend a rear, which will be more effective when off-road hill climbing,” said Sebastian Civitarese.
How fast can you go with diff lock on?
How fast can you drive when the differential lock is engaged on the vehicle? When using the differential lock, your speed should not exceed 25 mph.
Is limited slip better than a locker?
Limited slip differentials are suitable for most driving conditions. This differential’s purpose is to make sure you have the ability to drive under normal conditions without any mishaps. However, selectable lockers make conquering extreme driving conditions possible!
When should you not use a diff lock?
First, a diff lock should not be engaged for on road driving, unless weather conditions such as snow or ice mean that extra traction is required. Use your locking differential when you want to go off road, for driving on difficult terrain, such as dirt, gravel, mud or snow.
Can you turn on diff lock while driving?
Do you use diff lock in mud?
As the name suggests, a diff-lock locks the axle so that the two wheels turn at the same speeds. Here’s an example of when this is useful: you’re driving in muddy conditions and one wheel starts to spin in deep mud while the other wheel is on firm ground.
Some vehicle manufacturers will allow the differential locks to be engaged while moving but only if the vehicle does not exceed 40kph and there is no wheel spin. Let up momentarily on the accelerator pedal to relieve torque on the gearing and allow the sliding clutch to fully engage.
Should you lock your diff on sand?
Having a rear differential lock, like the one in the Ford Everest 4WD, can be handy if you’re on a section of sand that’s very bumpy and is likely to cause your 4WD’s wheels to lift off the ground. An engaged rear differential lock will ensure there’s no loss of forward momentum…
