diff lock

[Natt]

Morning all, As some of you know, this is my first landrover i have owned, few Q's

on the transfere box it has diff lock.....how does this work??? can someone please explain this .....nicely


Also, when getting my boat up the ramp and parked around the corner (boat is a bit over 3t) is it ok to use low gear (not the diff lock part just low range)
without doing any damage, hopeing to get a few answers today as i go away for work Monday and wont be on line, Thanks in advance Natt

PS; Its a 2005 130 Defender

The centre difflock is engaged by shifting the little gear lever to the left and disengaged in similar fashion by moving the lever to the left again. this can be done in "High-" and "Low-" ratio, even "on the move" although some people may have reservations doing so.
The difflock locks the differential in the TC, making basically a straight connection between front and rear axle, both of which will then rotate at the same speed. The differential in the TC allows for different rotational speeds of the axles as, e.g., when turning where the rear axle will have to run a smaller turning radius compared to the front axle, hence moving at lower speed. You will feel that your steering will be a bit "stiffer" when difflock is engaged. All this means that your difflock should be disengaged on grippy surfaces to avoid transmission wind-up and consequently damage to the TC. Use it on loose surfaces when there is any risk of getting stuck.
And yes, you can use low ratio when pulling your boat out of the water (in fact, it is rather recommended to do so).
Cheers

A couple of typo omissions in hastily typed answer ................. I think.
If ramp happened to be extra slippery, centre difflock could be engaged together with low range, for short distance, until u=you got back up to the 'grippy' surface again.

You have one of the few 4wds where you can select low range with an open centre diff. This means you can safely move your boat in low range (open diff). The low range with centre diff lock engaged is for off road conditions.

Just when to engage the centre diff lock has an many opinions as there are land rover owners. Simply, in slippery conditions the tyres will slip thus relieving pressure on the drive line (its the inability of tyres to slip on hard surfaces that causes that build up of pressure on the mechanicals as all wheels do not turn at exactly the same speed at all times thereby causing drive line components to twist. Preventing this pressure is what diffs do).

On a good ramp which has little or no slip just use low range by pushing lever forward . If it's slippery go forward and across to lock it but as stated unlock diff before turning on dry tar etc.

You need to be aware of the fact that the lever can be difficult to move when there is load on the transmission. It is quite normal to need to let the vehicle rock backwards and/or forwards slightly so that there is no load on the transmission.

If the vehicle is sitting still with a small amount of "wind up" on the transmission, the lever may be impossible to move.

You also need to realise that the CDL is not unlocked until the light goes out and isn't engaged until the light goes on.

Xtreme, I think the excitment of reply got the better of you.....re read your corrections, there is an error there that jojo got right before you inserted some big red stuff

thank you all that posted so quick, It has cleared a few things on my mind
