I had the same problem although both of mine had siezed up. I had Tony at
Transporter Supply in Surrey fix mine (01932 267979)
This was a posting that Tim Smith sent a while ago (I'm sure he won't mind me
reproducing it here!). I wasn't sure from your posting as to whether you had
already done all this!
Remove two nuts from servo bracket to allow the servo box to float free.
Keeping it STRAIGHT! get some one to work the dash valve. Box should move
in/out when active. If not dead servo, replace (can be split open to check
diaphragm, maybe goop-able) If servo is good, but diff lock wouldn't move
then remove the servo and its bracket. You need to drive out a 3mm drift
pin from the actuator shaft first DON'T bend the servo rod!!!!! Slip a
small nail into the 1/2" diam actuator shaft on the diff and go to it,
penetrating oil, bristle brush/emery cloth etc. and get it moving again..
This is the most likely failure point, gummed up from lack of use, so you
may wish to start here BTW. Once the shaft is free about 1/6th of a turn
of a tire will let the lock engage, about 1" travel inwards of the shaft.
If it is really freed up properly the tiny return spring inside the diff
will push the lock out to 'off' by itself. Very light force to move shaft
is all. At same time see if the dash light came on when shaft pushed in, if
not unplug the connector and bridge the terminals. After that check it as
needed, maybe a dead LED. There is an O-ring around an aluminium sleeve
(that is around the shaft). Sleeve will move out when you tug to expose
ring, replace that via dealer part, cheap.
Regards, Malcolm.
P.S Since having mine fixed, I do operate my diff locks once a week to keep them
free!
