Diff Lock

[td5130]

Can every Defender owner go out to there Defender and grab hold of the diff lock lever and see how many positions the lever has from diff lock to unlock left side being locked and right side unlocked mine seems to have 3 positions lock, unlock and nowere but in nowere it moves itself back to unlock and today in lock it moved itself to unlock

mine unlocked twice on the weekend i thought it was just me not putting it thru properly i was switching between high and low for about five hours and thought i might have made mistake when it did pop out after a couple of gear changes it jumped into neautral........

Mines not coming out of gear its coming out of diff lock and there seems to de 3 positions on the stick instead of 2

working for a transmission and gearbox company i have seen this a few times, the pivot on the selector fork in the transfer case has a brass bush which can sometimes wear. I had it on mine when i first bought it but using esso lt71141 oil a decent stabilizer has seemed to fix it in mine. it mainly happened when it was hot. As for the ones we have repaired it is mainly due to lack of lubrication, due to oil leaking and stuff all oil in the transfer case. hope this helps

I am using good oil penrtie MTF 95 So does this meen I have to remove the box to fix it

you push it to the left and it klicks back to the middle push it to the right and it clicks back to the middle

Move the vehicle slightly - drive forward or back, so the gears mesh in and engage.

or, I'm not understanding what you're saying.

grab hold of the diff lock leaver and push it to the left and it locks the diff then move it back to the unlock position and there is a small clik and diff unlocks but then I can move it to the right as well and back again and get the same click I seem to have a mistry spot that does nothing Problem is when in the left position and locked it is only just in and has come out twice on its own

All I can say is that mine has two definate positions, it never feels like it wants to stop in the middle.
When engaging and disengaging I found it neccessary to put the gearbox in neutral to ensure the cdl went in easily and properly.

Riped up the floor to day and all I can see is a limit plate on top of the transfer lever that is stopping the lever from going over to the left and engaging diff lock. So what I have done is left out the plate for now and will see what happends but I think the real problem is inside the front housing of the transfer case :BigCry:

From you user name I assume you have a TD5 130, which has an LT230 t/case.

If you look at how the diff lock works in an LT230, the lever has an infinite number of positions between fully left and fully right.

There is a linkage between the lever in the drivers cab and a lever on top of the front extension on the LT230. Land Rover has devised several variations of this linkage over the years - ranging from ok to very bad engineering (and not necessarily getting better as years advanced). All in my experience have thin wall plastic bushes that wear out. With some, correct adjustment and replacement of worn parts to eliminate lost motion is important.

Inside the extension housing, the difflock lever pushes against a spring. The spring pushes the selector fork to engage the diff lock, once the dog teeth are in alignment. So if the lever in the cab is fully left, the dog teeth may not have aligned, and not be locked.

The spring also has to push against the indicator lamp switch. If the switch is adjusted a smidgen too far down, or is sticking, it can prevent the diff locking (regardless if the lamp is illuminated).

I suggest looking for 2, 3 or more positions is miss-directed.

First of all I would would look underneath where the linkage comes from the top of the gearbox to the top of the extension housing on the LT230. Give everything are good wash if there is a deal of mud and crap there, then spray liberal amounts of your favourite spray lubricant at the connecting and pivot parts of the mechanism. Also spray the diff lock switch.

Operate the lever several times and repeat the lubricant spay.

Get someone to operate the lever, while you watch what is happening, looking for lost motion - motion at the lever in the cab that is not producing proportional motion at the lever on top of the front housing of the t/case. The lost motion can be due to tilting or twisting of the intermediate lever where it pivots on the side of the gearbox (the plastic bushes that wear). This lost motion is made worse when the different parts (including difflock switch) are not free to move.

Its Fixed Its Fixed Its Fixed got it sorted to day I pulled all the floor mats and the center hump and drivers floor and removed the diff lock actuator and could not find any thing wrong so I put it all back together and wile I was doing it I adjusted the piviot point arm that bolts to the side of the gear box I wound it out 2 turns and it fixed every thing that was wrong So if you ever find the diff lock playing up check all the linkages and adjust them first

Thanks everyone for your help
