Thread: CDL usage ???

Its a good habit to get into engaging it as soon as you come off the bitumen. It dos'nt matter what range you need to go into after that, but you dont have to worry about the CDL untill you hit the bitumen again. Its too late to engage it once your in a jam??. Also using it all the time whilst off road ensures it works when you need it. Your dash will have a light in it depending on year model as I think the 89 model hade it on the l/h of the dash next to the heater controls, maybe?????.Whatever the case have a good reliable indicator light. Just ask MickG!!!.

Regards Justin

Just adjust by screwing inwards until it lights up when Diff Lock is on fully and positively. Do NOT screw in too far!

CDL can be engaged at any speed. The only time to NOT engage is when the diff is actually working, i.e. turning corners, loss of traction, etc...

Changing from Hi-Lo should only be done at speeds no faster than a walking pace.

The Army doctrine for the CDL in their 110's is everytime you go off road, first thing on is the CDL. by habit I usually do it but the other weekend I had to have 2 stabs at a mud obstacle, being Tail end Charlie I thought it may have been due to the ground torn up by the other 10 vehicles before me but to my dismay I had forgot the CDL..put it on and presto up and over first try

In my experience, almost everywhere off the bitumen. The theory says engage it before you hit an obstacle.

You'll find it faster & more stable on high speed dirt with CDL in. Just knock it out for tight, 3 point turns where there's no tyre slip.

same here

The centre diff lock uses springs to engage it - the lever only applies pressure on the spring and position of the lever does not mean that the diff is locked or unlocked.

The switch should be adusted down the minimum necessary for it's contacts to close. If it is too far down, the spring can not lock the diff.

The switch is on top of the front output shaft housing, behind the linkage from the diff lock lever. It has 2 spade terminals on top for the wiring. The body of the switch is threaded and screws into the housing. A lock nut prevents it from loosening.

The switch is in series with the indicator lamp in the dash panel. The wiring goes from the lamp to one spade terminal on the switch, then from the other switch terminal to earth.

I had to drive through a forest at one time to get to work,, loose gravel yarda yarda--
about 40 kays each way,, at first the CDL was great,, then I discovered the extra fuel bill,
( stop laughing please--)

cdl adds maybe 10-15 %

mind you, the daily trip only took, um, er -- 30 mins with the cdl in---

not really sure if it was more fun with it in or out

I can't believe all you fella's use the CDL on gravel.
I drive the stuff everyday and never want to use it. CDL on fast gravel = understeer
It's got to be really slippery for me to throw it in, otherwise it's much nicer without it.
