How does a shift on the fly actuator work?

How does a shift on the fly actuator work?

Your system is a shift on the fly, which has an electric actuator that shifts the transfer case into 4WD and signals the front axle actuator to engage the differential by moving a spline sleeve onto the axle thereby stopping the front differential from”freewheeling” and effectively putting the vehicle in 4WD mode.

What is the actuator on a 4 wheel drive?

The actuator is a component found mostly on modern four wheel drives and is designed to electronically engage 4 wheel drive. It accomplishes this by means of a small electric motor bolted onto the transfer case that shifts a pin in place to lock the center transfer differential.

How does a 4 wheel drive light work?

It accomplishes this by means of a small electric motor bolted onto the transfer case that shifts a pin in place to lock the center transfer differential. The actuator allows you to shift from 2WD to 4WD on the fly and back to 2WD without stopping and can be engaged and disengaged by means of a switch inside the cabin, usually on the dashboard.

What happens when I change the flashing light from 2WD to 4WD?

When change 2wd to 4wd and vice versa, the actuator moves the actuator shaft, and its position is monitored by the free wheel engage switch. If the actuator is moving and the shaft is free, then the next check is the free wheel engage switch. It either needs replacing or cleaning (bad connection).

What does the blinking 4 wheel drive indicator mean?

So what is that 4 wheel drive indicator blinking on your dashboard means? The purpose of the 4 wheel drive light is to indicate when you have engaged 4WD mode by selecting 4H. When the light flashes continuously for more than 30 seconds it signifies there is a problem somewhere on your drivetrain system and that 4WD has not engaged properly.
