What 4WD has low range?
In 4L (four-wheel drive, low range), all four wheels are driving your vehicle and a low gear ratio is being used. Your vehicle’s wheels will turn much more slowly than they would in high range, so slower speeds and more torque are the go.
Does 4 low lock the differential?
4 low is for slow crawling, 4 lock locks the differential so you can keep from getting (or get unstuck) stuck. Neither should be used on pavement and neither should be used at speed.
What is the difference between 4WD high and low?
Without an Auto setting, 4WD High is what you’d use in any situation that’s low-traction but relatively high-speed—a dirt road or snowy paved road. 4WD Low is strictly for slow off-roading or places where torque multiplication would really help you out (like deep sand).
How does the transfer box work on a Land Rover?
The transfer box is the heart of the beam axle Land Rovers’ four-wheel drive system. It transfers the drive (from the gearbox) across and out at the front and rear of the transfer casing to drive the propshafts to the front and rear axles.
Why do you need a transfer box in a car?
A so-called centre differential inside the transfer box allows the relative speeds of the front and rear propshafts to vary, thus allowing the front axle to rotate faster than the rear, which it needs to do when turning a corner.
Is the LT230 a rear wheel drive transfer box?
Unlike the earlier transfer boxes on Series Land Rovers which had rear-wheel drive and manually selectable front drive, the LT230 provides permanent drive to both axles, thanks to its integral differential.
Where does the drive go in a transfer box?
It transfers the drive (from the gearbox) across and out at the front and rear of the transfer casing to drive the propshafts to the front and rear axles.
Why is my transfer box in low range?
Overdrive! However, if your rotary potentiometer is faulty, there’s a small possibility that exercising the shift motor in this way may cause it to get stuck in Neutral or Low Range. The potentiometer voltage is the only feedback that the NV225 transfer box ECU receives to tell it where the shift fork/rail is and therefore which range it is in.
How does the transfer box work in a car?
The transfer box is, of course, driven by the gearbox mainshaft which protrudes into the transfer box casing to drive the transfer gear. This, in turn, drives the intermediate gear, which continually drives the high and low ratio output gears on the right-hand side of the transfer box.
Unlike the earlier transfer boxes on Series Land Rovers which had rear-wheel drive and manually selectable front drive, the LT230 provides permanent drive to both axles, thanks to its integral differential.
Which is the best Land Rover transfer box?
LT230: The best ever transfer box? The LT230 is the most prolific Land Rover transfer box, and it’s certainly stood the test of time and survived arduous use.
