Rear Difflock problems Iveco 40-10

My difflock mechanism is not engaging the lever in the cab is working but the lever on the diff wont budge. can I just remove the unit from the diff to free it up?

Has anyone else had the same problem?

Rear Difflock

Yes Graysworld!

I've had the same problem (mine went in after a struggle but wouldn't release without tapping the lever with a hammer!) and just fixed it last week. I believe it's a common problem on 40.10's. Yours should be the same as on my WM. Basically it just gets too tight for the springs.

Take the mechanism off the axle, 4 bolts (2 long, 2 short) after disconnecting the pull and return springs. It works via a peg which locates in slots in a collar located on splines on the half shaft. There's a roll pin on the lever; if you were to drift it into the housing it should be possible to release the cross-shaft and get the pin out again but I didn't fancy trying it just in case! However, between the lever and the housing you'll see a felt washer (when the muck's cleaned off). The lever was almost solid but after soaking the felt washer in WD40 and leaving in the vice overnight it was much better. Another overnight soaking and working the lever back and to and it was nice and free. Then I soaked some '3-in-1' oil into it. Put it all back together and check the return spring can pull the lever back again and that the peg is well clear of the slot when in the 'off' position. (Jack up the left hand wheel and turn it by hand). While I was at it I lubricated the cable and the clevis pin on the other end under the cab floor. I suppose you could do the same without removing the assembly just by cleaning the felt and oiling it in situ but I wanted to see how it worked! A drop of oil now and again is now on my regular service list!

Apparently the RH shaft is driven all the time, the LH one can be locked with the peg engaging one of several slots in a collar which is splined on to the LH shaft (the LH shaft has two sets of splines, one at the end for the diff and another about 6" along the shaft for this lock. So it's not so much a difflock as a halfshaft lock, but the effect is the same anyway!

Hope this works for you too!

Cheers

Nigel.

Smile Difficult Diff

Hi Graeme
Yes mine was the same, the lever operated, but the cable was rusted solid, the throw is very short, so make sure the cable is actuating the lock.

A basic question

Hello all,
I have a very basic question about the rear diff lock: what is the position of the lever in the cabin to operate de lock? To the front or to the back? I'm a firefighter and just moved to another brigade that has an IVECO 40.10 but there is no user manual or nobody that knows even what the lever is for...

Hi,
No experience with Ivecos, but....if you jack up one back wheel and try to rotate it, if it turns (whilst the other rear wheel is on the ground) then the dif is not locked. Throw the lever, if the wheel will now not turn, diff lock is engaged and working.
It usually wouldn't matter, but from Nigels post, i guess you should jack up the L/H wheel to do this.

Hello Sam,
thanks a lot for the answer. I will try it like you described. I've just read an IVECO Daily Repair Manual and there is a rear differential that looks just like the one used on the 40.10, with the locker mounted on the left wheel axle.

Return spring

Hi all,
the lever in the cabin operates the diff lock but when freed up the return spring won't pull the transmission lever back to the initial position. I have to pull it by hand or with a hammer. The return spring is too long.
Anyone had this problem?
